    Abstract: An apparatus is disclosed for the continuous manufacture of fiber reinforced plaster sheets which apparatus includes a conveyer for supporting a plurality of sheet casting moulds, a casting station for casting slurry into said moulds and a fiber station at which means are provided for depositing fiber for reinforcement across the surface of the casting slurry. The apparatus also includes a pair of rollers having radial extensions to force the fibers to or adjacent the lower surface of the cast slurry. A second fiber depositing means is also provided for depositing a second batch of reinforcing fibers across the surface of the slurry and a second pair of rollers having an open mesh surface are provided for forcing the second batch of fibers into the slurry to a level at or adjacent the upper surface thereof. The fibers used may be sisal or fiberglas as individual randomly oriented lengths, continuous meandering strands or a random mat deposited over the surface of the slurry.

    Abstract: A machine for packaging articles such as meat slices; the package is formed by opposed films one of which is vacuum formed to form cavities and the other is applied thereto to complete the package; the film that is vacuum formed is heated gradually (not on-off) and substantially uniformly throughout its thickness and in the heating step, the temperature of the film is maintained at a predetermined minimum; the packages are made first in units containing two cavities and the units are perforated at a center point and the package units are nitrogen-purged at the center aperture; the films making up the packages are registered relative to a label pattern on the cover film and the cavities in the bottom film, through tension variation, under the control of a PE cell; the machine includes conveyor means intermittently advanced, the rate of speed being variable but of dwell intervals that are of predetermined length independent of the speed during travel; final cutting means includes circular friction grippers for pulling a package unit having two packages therein, and rotary cutter elements.

    Abstract translation: 用于包装肉片等物品的机器; 包装由相对的膜形成，其中一个被真空成形以形成空腔，另一个被施加到其上以完成包装; 真空形成的膜在其整个厚度和加热步骤中逐渐加热（非开 - 关）并基本均匀地加热，膜的温度保持在预定的最小值; 包装首先以包含两个空腔的单元制成，并且单元在中心点被穿孔，并且包装单元在中心孔处被氮气吹扫; 在PE电池的控制下，通过张力变化，构成包装的膜相对于覆盖膜上的标签图案和底部膜中的空腔进行登记; 机器包括间歇地提前的传送装置，速度可变，但是具有预定长度的停留间隔，与行进中的速度无关; 最终切割装置包括用于拉动其中具有两个包装的包装单元的圆形摩擦夹持器和旋转切割器元件。

    Abstract: A CONTROL ARRANGEMENT FOR A PLSTICS MATERIAL MOULDING PLANT IS DISCLOSED. THE ARRANGEMENT COMPRISES AN ENDLESS CONVEYOR FOR CARRYING A PLURALITY OF MOULDS DISTRUBUTED ON THE CONVEYOR AND MOULD FILLING MEANS FOR SUCCESSIVELY DISCHARGING MOULE DILLING MATERIAL INTO THE MOULDS. THE CONVEYOR IS MOTIVATED SO AS TO POSITION THE MOULDS SUCCESSIVELY AT THE MOULD FILLING MEAND AND THE CONVEYOR IS COUPLED TO A ROTARY SELECTOR OF A SELECTOR SWITCH. THE FIXED CONTACTS OF THE SELECTOR SWITCH ARE CONNECTED TO A PLURALITY OF FIRST CONDUCTORS OF A CROSSED-BAR SWITCH. THE CROSSED-BAR SWITCH IS PROVIDED WITH A PLURALITY OF FURTHER CONDUCTORS WHICH ARE SELECTABLY INTERCONNECTABLE TO THE FIRST CONDUCTORS. THE FURTHER CONDUCTORS ARE CONNECTED TO CONTROL MEANS FOR CONTROLLING THE QUANTITY OF MOULD FILLING MATERIAL DISCHARGED INTO THE RESPECTIVE MOULDS IN DEPENDENCE ON THE INTERCONNECTIONS BETWEEN THE FIRST AND FURTHER CONDUCTORS.

    Abstract: A SEMI-AUTOMATIC PLANT FOR CASTING BUILDING COMPONENTS IN WHICH HORIZONTAL MOULDS HAVING SWINGABLE SIDE WALLS ARE CONVEYED PAST A NUMBER OF STATIONS FOR SHUTTERING, POURING, HARDENING, REMOVING OF THE SHUTTERING AND CLEANING. THE SHUTTERING STATION AND THE STATION FOR REMOVING THE SHUTTERING ARE PROVIDED WITH SWING ARMS DRIVEN BY A COMMON SHAFT AND ADAPTED TO SWING THE SIDE WALLS FROM

    A SWUNG-OUT POSITION INTO A SWUNG-UP POSITION AND VICE VERSA. THE SWING ARMS ARE COOPERATING WITH SWINGABLE SPRING BOWS MOUNTED ON THE MOULD BOTTOM AND ADAPTED TO LOCK THE SIDE WALLS IN SWUNG-UP POSITION AND TO CARRY THEM IN SWING-OUT POSITION.

    Abstract: An automatic block-forming apparatus in which the blocks are formed by compressing the block material in a mold box until the material takes the shape of the mold cavity. The compression stroke is automatically timed and compared each cycle to a range of acceptable times that will result in a block having an acceptable density. If the compression time falls outside of the acceptable time range, a control circuit sounds an alarm and indicates whether more or less material must be fed into the mold box to either increase or reduce the density of the compressed blocks.
