Abstract: 960,539. Anti-dazzle rear view mirrors. T. FAULHABER, and G. BECKMANN. Sept. 18, 1962 [Sept. 20, 1961], No. 35509/62. Heading B7J. [Also in Division G2] A rotatable rear view anti-dazzle vehicle mirror comprises a housing 11, Fig. 1, in which are arranged a plain glass double plate 1 and a mirror double plate 2 under pressure from a spring 12 and spaced from the plate 1, synthetic plastic lamination foils 3 welded at their periphery and providing a liquid space 5, and a liquid conduit 9 connected to a pump 17 which may pump light-absorbing liquid to and from the space between the plates 1, 2 to vary the reflecting quality of the mirror. The pump comprises a rigid part 30, and a flexible diaphragm 31 riveted at the edges thereto and which may be drawn away from the base 30 by pulling on a rod 34 attached to the diaphragm until a retaining plate 41 engages in a locking position in a groove 42 in the rod. In this retracted position liquid is withdrawn by suction from between the plates 1, 2, the mirror is undimmed, and the liquid passed into the pump. Occluded air within the tube 9 and pump may be expelled through a filler tube 27 after a plug 29 has between withdrawn and pinch clips 25, 26, 28 have been sequentially applied or removed to push the air upwardly. When the mirror is to be dimmed again to prevent dazzle, the knob 44 on the rod 34 is pushed downwardly against a spring 45, the plate 41 is removed from the groove 42 and the rod and diaphragm allowed to snap back to the position shown, thus forcing liquid from the pump back into the space between the plates 1 and 2. In a modification, Figs. 7 and 9 (not shown), the pump comprises a flexible tube which is compressed by a pivoted hand lever. In another embodiment, a pivotally mounted internal mirror, Fig. 3, has a pump 17 which may be compressed by a lever 51 attached thereto, and the mirror plate 2 is under pressure from a flat plate spring 12 (see also Figs. 4 and 5, not shown). An individual pump may operate several mirrors, and several sealing devices for the plates 1, 2, and the mirror housing are described and shown.

Title: Process for refining benzole with sulphuric acid
IPC: C07C7/171
Filed: 1963-09-10
Abstract: Crude benzole or a fraction, e.g. a benzene fraction, thereof is refined by spreading as a thin film on a surface and dispersing sulphuric acid in the film in the form of finely divided droplets. Preferably benzole and sulphuric acid are fed to the same or separate, flat or conical discs on a rapidly rotating shaft in a cylindrical chamber so that they are flung against the wall; using two discs benzole is fed to the upper and acid to the lower.  In one embodiment the apparatus is divided into three compartments each provided with two dispersing discs on a common shaft; the products from each compartment are separated and partially purified benzole fed with fresh acid to the next compartment. Acid from the final stage may be re-used in the first stage.  The benzole is neutralized and may be distilled.  In one example five fractions from benzole are separately refined each with about 8% by weight of oleum corresponding with 106% sulphuric acid; in another a toluene fraction is refined with 6% of 96% acid.

Title: Improvements in or relating to Machines for Deforming Sheet Metal
IPC: B30B15/28
Filed: 1968-07-26
Abstract: 1,195,448. Deforming metal sheets. PROMECAM SISSON-LEHMANN. 26 July, 1968 [26 July, 1967; 11 June, 1968], No. 35700/68. Heading B3E and B3W. A machine for deforming sheet metal such as a shearing machine or a folding press comprises a fixed bolster 2, a moving bolster 3 and a fixed frame 1 having a pump unit for supplying fluid pressure for operating at least one thrust ram 4, the movement of the moving bolster 3 being controlled by a synchronizing device which maintains the bolsters in a predetermined relative angular position by the action of sensors 5 which detect angular deviations from this predetermined angular position and actuate a pressure medium distributor valve 7 which feeds the synchronizing device with fluid pressure, the sensor including a correcting device 26 which is actuable to modify the action of the valve 7 so as to compensate differences in elastic deformations under load of lateral walls 1c and 1d which support the bolsters. An inclination of the moving bolster 3 in the counterclockwise direction will create a high pressure in conduit 22a of the sensor circuit and a low pressure in conduit 23a. This pressure difference is transmitted to the correcting device 26 and forces piston 28 downwards. The movement of the piston 28 acting through a cable 10 pulls the valve 7 downwards so that conduit 23c is connected to discharge while conduit 22c is connected to the feed supply of the thrust rams 4. The two sensor rams which have opposite directions of action, then produce a couple in the clockwise direction. Microswitches 34 and 35 control the correcting device 26 so that the operation of the machine is stopped as soon as the difference in the deformations of side walls 1c and 1d reach a predetermined limit. A modification of the correcting device comprises a ram 38a, which is fed by conduit 23c, and ram 38b fed by conduit 22c which are connected by a pivotable lever 39. The pressure difference, created by counterclockwise inclination of the moving bolster 3 in the conduits 22c and 23c causes a lever 40 connected to the ram 38b to pull the valve 7 downwards via the cable 10.

Title: Improvements in or relating to apparatus for inflating inflation bags
Inventor: POHLER DERRICK MARSHALL
IPC: F02K9/72
Filed: 1959-10-22
Abstract: 904,345. Injectors. KIDDE CO. Ltd., WALTER. Jan. 20, 1961 [Oct. 22, 1959], No. 35794/59. Class 71. In an injector for inflating an inflation bag, a relatively slow-burning combustion substance e.g. cordite, is electrically ignited in a capsule 2, and the resulting combustion products are directed as a jet into the throat of the device 1 and gas e.g. carbon dioxide is released from a storage 6 to the throat to cool the jet of combustion products. When the charge is fired, rising pressure in the tube 3 closes a switch 4, causing storage cylinder 6 to release carbon dioxide through a tube 7. Alternatively the pressure of the combustion products may be used to release gas for cooling, either directly or by release of a latch holding the gas storage closed. A flexible shroud may be arranged around the efflux of the inflation device.
