    Abstract: PCT No. PCT/AU88/00212 Sec. 371 Date Dec. 21, 1989 Sec. 102(e) Date Dec. 21, 1989 PCT Filed Jun. 24, 1988 PCT Pub. No. WO88/10157 PCT Pub. Date Dec. 29, 1988.A vibration generator including an inertial body and a housing which are relatively movable and where hydraulic fluid is directed into the inertial body through a control valve mounted in the inertial body, the fluid being directed alternately into one or another working chamber which causes oscillation of the housing and any attached load. A wave form shape of pressure or flow rate of the hydraulic fluid flow is detected and used to control the frequency at which the vibration generator oscillates so that the frequency is maintained at a resonant frequency. The device has particular application in a frequency range of 20 Hertz to 1000 Hertz.

    Abstract: 25,385. Stewart, G. D. Dec. 1. Platen presses.-Guard for preventing accidents. A strip or plate of thin sheet metal A is hinged at H to the upper end of the platen P. The guard is connected by the lever and link L, L to the oscillating piece R. In the forward motion of the platen, from the position shown in Fig. 2 to that shown in Fig. 3, the guard A is thrown forward so as to cover the space between the platen and type bed.

    Abstract: A height adjustable urinal 200 integral with the cistern 101 of a domestic toilet comprising a cistern with a lid 102, opposing front and back walls 110, 101, and a base. The front wall comprises a section 114 hinged at its bottom such that it can be tilted forward, slide rails (122 figure 2) and a bracket (123 figure 2) are mounted to the back of the front wall section. A mount (221 figure 2) is slidably fixed to the slide rails and secured between the bracket. A urinal comprising a bowl (210 figure 2), and a tube like body 211 extending downwards from the bowl, the tube like body adjustably held in the mount and the bowl of the urinal above the mount such that in use the urinal and front wall portion are moveable between a closed position, wherein the urinal is held within the cistern and the front wall section is flush with the rest of the cistern, and an open position, wherein the front wall section is tilted forward and the urinal is exposed.
