Title: Improvements in steering-brake means for motor vehicles
IPC: B60T11/18
Filed: 1964-02-13
Abstract: 989,680. Fluid-pressure brakes. DEUTSCHE PERROT-BREMSE G.m.b.H. Feb. 13, 1964 [Feb. 15, 1963], No. 6075/64. Heading F2F. [Also in Division B7] In a vehicle braking system including pressbutton actuated valves for isolating the brake master cylinder from some of the brake cylinders at the wheels, thereby enabling the wheels to be selectively braked to assist the steering action of the steerable wheels of the vehicle, closure of either valve A or B in the supply lines 3, 5 for the brake cylinders of one axle of the vehicle results in closure of a valve C in a supply line 4 common to both brake cylinders on a steerable second axle so that only the remaining wheel on the first axle is braked upon actuation of the master cylinder. By means of bridge member 15 and rockers 16 each of push-buttons 21 protected by a flexible cover 24 is arranged to operate one of the valves A, B and, independently of one another, the valve C. Depression of either button 21 results in depression of the stem 9 and head 8 of the associated valve A or B and of the valve C to isolate the respective supply line 3 or 5 and the supply line 4 from chambers 7 interconnected by passages 6, 6<SP>1</SP>, 6<SP>11</SP> provided with a bleed valve 25 and supplied through a delivery pipe 2 from the master cylinder. Upon exerting a light force on the brake pedal fluid pressure in the chambers 7 retains the valve heads in the closed position and ejects the detached stem 9 of the valve C, which movement is transmitted to the button 21 to serve as a signal that the button may be released, the valve remaining closed so that a heavier pressure on the brake pedal produces differential braking until the pedal is finally released. In another embodiment the chambers 7 of the valves A, B and of the valve C are separately supplied by the master cylinders of a dualcircuit braking system.
Patent GB-452641-A (GB)
Title: Process for utilising film waste
IPC: C08J11/04
Filed: 1936-02-28
Abstract: Film waste material is freed from the gelatine layer, and then heated under pressure with water which has been so deprived of any acid-neutralizing constituents such as lime, magnesia, and iron, or so neutralized, that the acid freed by decomposition of the nitrocellulose during the pressure heating operation is not neutralized and can react on the albumin layer, whereby removal of this layer from the film waste and diminution of the viscosity characteristics of the nitrocellulose are simultaneously effected. The recovered nitrocellulose material may be used in the production of lacquers and varnishes.  The removal of the albumin layer is retarded if any additions which lower the surface tension are present during the treatment.  In an example, film waste is soaked in cold water and then in hot water.  The gelatine layer containing the silver is thus removed.  The film material is then heated with softened water until boiling point is reached in 1--2 hours.  Air is released and the autoclave then heated for 30--45 minutes, the pressure rising to 2,5 atmospheres above atmospheric pressure.  The pressure is maintained for several minutes.  The film waste is subsequently removed, washed, and dried at low temperature.

Title: Improvements in and relating to seismic prospecting
Inventor: BORKOVSKY GENNADY MIKHAILOVICH
IPC: G01V1/24
Filed: 1969-02-06
Abstract: 1,261,836. Seismic prospecting; automatic gain control. VSESOJUZNY NAUOHNOISSLEDOVATELSKY INSTITUT GEOFIZICHESKIKH METODOV RAZVEDKI. 6 Feb., 1969 [8 Feb., 1968], No. 6353/69. Headings H4D and H4R. [Also in Division G4] Multi-channel seismic signals are fed through a commutator to a single stepped-gain amplifying channel which provides dynamic range compression, the amplified signals being recorded in digital form. In the embodiment shown, seismographs 1 are connected through pre-amplifiers 2 to commutator 3. Commutator 3 couples the seismic channels in turn to amplifying channel 4, each for a 30 Ásec. period. Amplifying channel 4 comprises n cascaded stages 6, 7, 8, each with a gain which is some multiple of two (e.g. eight), coupled to the signal inputs of n + 1 gates 9, 10, 11, 12. The gate outputs are coupled to sample- and-hold circuit 24 and level comparator 13. Timer 18 provides pulses at 5 Ásec. intervals to one input of a coincidence gate 14 coupled to a counter 15 (e.g. comprising bi-stables 16, 17) whose logical "1" and "0" outputs are the inputs for n+ 1 coincidence gates 20, 21, 22, 23. At the start of a 30 Ásec. period of commutator 3 the counter outputs give coincidence in gate 20, thus opening gate 12 to pass signals with an amplification of 8<SP>3</SP> to comparator 13. If the amplified signal level exceeds a reference level in the comparator, a comparator output signal is given and will result in a coincidence signal from gate 14 after 5 Ásec. This coincidence signal advances counter 15, thereby closing gate 12 and opening gate 11 to pass signals with an amplification of 8<SP>2</SP> to comparator 13. If these amplified signals still exceed the reference level, counter 15 is again advanced after a further 5 Ásec. interval. This procedure repeats until the reference level is not exceeded, the amplification then being held constant. 5 Ásec. after the nth pulse from timer 18, circuit 24 is allowed to sample the amplified signal and the sample is converted to digital form by A-to-D converter 25 and recorded magnetically at 26. After the sampling, timer 18 resets counter 15. During this reset a code signal representing the prevailing amplification factor is derived from the counter 15 outputs and stored in memory 19. The stored signal is then recorded at 26 and the memory is erased. -The digitally recorded seismic signals and amplification code signals may be played back, amplified and shaped at 27 for application at 32 to a digital computer, and the seismic signals may be reconstituted and recorded in their analogue form with their original dynamic range by applying the output of amplifier/shaper 27 to D-to-A converter 28, dynamic range restorer 29, de-commutator 30 and analogue recorder 31.

Abstract: 788,033. Protective arrangements ; transmission line arrangements. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. March 2, 1956 [March 18, 1955], No. 6573/56. Class 38 (4). A power line with phase conductors 6 starts from a station 1 comprising a transformer 2 which is connected to a bus-bar 5 mounted between supporting poles 3, 4, the transformer neutral being directly earthed. On the supporting poles 7 for the power line are located overhead earth-wires 8 which are separated from the overhead earth-wires 10 of the station by means of an insulating link 9 at the pole 4. The wires 10 are metallically connected with the earth network 11 of the station, and the poles 7 are earthed by connections 12 which may be interconnected by a ground wire 13. The purpose of the link 9 is to prevent the passage of excessive current through the wires 8 in the event of flash-over between the lines 8 and 6 in the neighbourhood of the station. The provision of the link 9, which may consist of a thread of insulating material, increases the resistance of the earth fault circuit so that the current therein is considerably reduced. The insulation of the link 9 must be sufficient to prevent flash-over when lightning strikes the overhead earth-line. When a counterpoise wire is located in the ground between the earth connections 12, it may be suitable for this wire also to be metallically isolated from the earth network of the station.
