Title: Improvements relating to emulsifying and homogenising apparatus
IPC: B01F11/00
Filed: 1936-02-08
Abstract: <PICT:0470083/III/1> In emulsifying-apparatus, pressure produced by relative movement of a piston and cylinder forces the material to be emulsified through two or more apertures arranged to form jets which impinge on one another or which impinge against an obstruction, and enter a delivery tube.  Externally adjustable means are provided to adjust the extent of the apertures to vary the thickness of the cream and to allow the apertures to be freed if they become choked. According to the arrangement shown in Fig. 1 a cylinder C<1>, having an agitator D attached, and fitting over a tubular piston E, is reciprocated by handle B.  The material in the container enters through apertures f<4>, axial passage f<5>, past ball valve H and is force  out <PICT:0470083/III/2> <PICT:0470083/III/3> <PICT:0470083/III/4> through holes j in a delivery tube J fitted to the top of the cylinder.  These holes are diametrically opposed so that the jets impinge and their area is regulated by a plunger K operated by milled nut k.  The axial passage f<5> is continued through the ball and socket joint e and f and is closed by the externally operated conical valve G, which permits the de-salting of the butter used for making artificial cream by means of hot water. In the emulsifying valve shown in Fig. 2, the material is forced through holes c<9> and the jets impinge against the opposite wall of an annular chamber e.  The jets are varied by movement of a plunger K. Fig. 3 shows a device similar to that shown in Fig. 1 except that the tubular piston E is hinged to the tubular fitting F and the delivery pipe J is fixed in a thimble j<1> which is screwed into the cylinder head.  Opposed apertures j are provided in the end of the thimble. In the construction shown in Fig. 4, a solid piston E<2> is used and is linked to the handle B.  The material is drawn from the container through a openings c<8> and is forced into an annular chamber c<10> from which it passes through apertures c<11> into a delivery passage N formed in a screw plug n which adjusts the size of the openings c<11>.

Title: Improvements in automatic compressed air brake systems
IPC: B60T15/54
Filed: 1949-02-15
Abstract: 661,572. Fluid pressure brakes. VERWALTUNGSGES DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 15, 1949 [Feb. 16, 1948], No. 4158/49. Class 103 (i). The triple valve of an automatic compressed air brake system has provided on the brake pipe 1 side of the slide valve piston 3, a guide bush 4, on which is pivoted at 6 a rocker 5, one end of which is opposite the spindle 8 of a local release valve to atmosphere. When during a brake application the pressure in the train pipe is initially reduced, the leftward movement of the piston 3 and guide bush 4 causes the rocker 5 to open the release valve 8, 9, thus providing an accelerated reduction of the pressure in the train pipe. Just after opening the valve 8, 9, the lateral extremity of the rocker 5 abuts against a shoulder 10 on the valve casing causing the rocker to pivot about pin 6 and become disengaged from the valve 8, 9 which may then close. The rise in pressure in the brake cylinder III causes a plunger 11, 14 to engage in a groove 12 in the guide bush 4, thus rendering it inoperative for any immediately subsequent reductions in train pipe pressure. The guide bush 4 will only be released when the brake cylinder pressure has been reduced to such a value that the train pipe pressure can push back the piston 14.

Title: Improvement in hydraulic locking means for motor vehicles
IPC: E05B65/38
Filed: 1938-02-11
Abstract: 492,864. Hydraulically - operated fastenings. WEBB,D.E. Feb. 11, 1938, No. 4392. Convention date, Feb. 20, 1937. [Class 44] A lock mechanism for the doors of motor road vehicles of the kind having two doors on each side with their hinges remote from one another, comprises hydraulic transmission mechanism situated in the jamb separating the two doors on one side, which mechanism transmits the motion of the usual manually operated bolt on one of the doors to a bolt arranged to lock the other door. The jamb on the other side of the vehicle may be provided with two hydraulically operated bolts, one for each door, connected to the transmission line by a pipe. The bolt 16 of the lock 12 on one of the doors passes, when projected, through the wall 30 of the jamb and through an opening in the end of a casing 28 housed in the jamb, thus locking the door and displacing a piston 38 in the casing 28. The bolt 48 in the casing 28 is projected by the displaced liquid acting on the piston 42 to lock the other door. A casing 128 having two hydraulically operated bolts may be connected to the casing 28 by a pipe 24 to lock the doors on the other side of the vehicle. In this case the piston 38 is made larger in diameter than the pistons 42 which actuate the bolts 48. Springs 40, 44 return the pistons and bolts to their retracted positions when the key-lock 12 is operated to release the doors. The liquid, which is preferably a mixture of oil and alcohol, is prevented from coming in contact with, or passing, the pistons by washers 52. A passage 56, closed by a screw 62 and a check valve 64, allows liquid to be added to the system whilst a passage 66, closed by a screw 70, allows liquid to be removed. In a modification, the two bores in each casing are offset from each other so as to enable the mechanism to be accommodated in jambs which are too narrow to allow the bores to be arranged in axial alignment.
