Abstract: 1,234,652. Electro-photographic process. XEROX CORP. May 27, 1968 [June 1, 1967], No.25211/68. Heading G2H. A method of imaging comprises the steps of:  providing an imaging member having a substrate supporting an overlayer of electrically insulating solvent softenable material containing electrically photo-sensitive fracturable or particulate material, uniformly electrostatically charging the member and exposing the member while the softenable layer is soft to an imagewise pattern of electromagnetic radiation to form a migration image. If the substrate is conductive, the member is charged conventionally, e.g. using a corona charger, and if insulating the member is charged with the substrate contacting an earthed plate or by using two corona chargers one on each side of the imaging plate. The softenable layer may be a plastics material e.g. a polyolefin, a polystyrene or an epoxy or acrylic resin, and the photo-senstive material may be inorganic e.g. selenium or an organic dye pigment. The plate is imagewise exposed to visible U.V., infrared or X radiation, while the softenable layer is softened in a liquid or vapour solvent or by heat. Suitable solvents include, for example, acetone, chloroform, ethyl ether, benzene and toluene. An additional uniform exposure to activating electromagnetic radiation may be included between the charging and imagewise exposure.

Abstract: 1,238,974. Antiskid brake systems. ALFRED TEVES G.m.b.H. 14 Oct., 1969 [18 Oct., 1968], No. 50442/69. Heading F2F. An antiskid device for controlling the hydraulic pressure in a motor vehicle brake system in dependence on the acceleration and speed respectively of wheels of the vehicle by means of a signal transmitter at the input of a control system and an electronic circuit which triggers a final control element 5 such as an electromagnetically operated valve to influence the hydraulic brake system is so arranged that the signals produced for triggering the element 5 are produced in dependence on acceleration thresholds and speed thresholds. A D.C. generator 1 rotating with the wheel supplies a voltage, proportional to the rotary wheel speed, to a control system 4 whose circuit is closed by a pressure switch 6 when the brake pedal is operated and whose output triggers the element 5 when the input voltage is of a value lower than that corresponding to the initial speed. If the valve 5 is closed by the output signal of control system 4 the hydraulic pressure provided by master cylinder 7 cannot rise further and a bypass to a supply tank is opened, thus reducing the braking pressure. The deceleration threshold control system 3 receives its input from the same generator via a differentiating circuit 2 and controls the brake pressure in conventional manner by closing the input valve and opening the output valve at a predetermined deceleration value.

Abstract: 1290245 Transistor pulse circuits; pulse modulation circuits INTERNATIONAL BUSINESS MACHINES CORP 13 Oct 1970 [16 Oct 1969] 48516/70 Headings H3T and H4L [Also in Division G4] A delta encoder or decoder (see Division G4) includes a shift register which supplies a high signal (see the signal at times t 1 , t 2  on "line 33" in Fig. 2) whenever four successive identical bits are detected in the encoder output or the decoder input. This signal comprises one input, IN1 of an exponential level stepper (Fig. 4), the other input, IN2 comprising clock pulses. The high level signal at time t 1  switches off a transistor T2 and a negative clock pulse switches off a transistor T1 so that a transistor T3 conducts. The voltage change transmitted by a "pump ' capacitor C1 causes a transistor T5 to conduct and a "hold" capacitor C2 is therefore charged. Thus each time a clock pulse occurs whilst the signal on line 33 is high the voltage across the capacitor C2 increases in steps as shown at "line 36" in Fig. 2, the amplitude of successive steps increasing exponentially. When the signal on "line 33" drops to its low level the capacitor C2 discharges through resistors R1 R2 to provide an exponentially decreasing voltage. The signal shown at "line 36" in Fig. 2 is fed to the base of a transistor T8 in a pulse width modulator supplied by clock pulses at an input 1N3. When a positive clock pulse is applied to the input 1N3, a transistor T6 becomes non- conducting and a capacitor C3 is charged via a diode D3 and a resistor R4. When the clock pulse disappears a transistor T7 conducts and a current I flows through the capacitor C3. The voltage across the capacitor C3 decreases to -Vh where Vh is the voltage across the capacitor C2 thus the transistor T8 conducts and the transistor T7 becomes non-conducting. The width of the output pulses at 3 see "line 38" of Fig. 2 is given by C3.Vh/I which is proportional to Vh since I is constant.

The switch is basically that of Specifications 1,216,186, 1,306,072, 1,306,073, 1,306,074 and 1,306,075. The interponent construction is detailed in copending application 40949/69. In Fig. 19, a flat U-shaped core 141 is spring- urged (147) against a pin 145 carried by a common stop-plate 134. The core carries a winding 152 on a bobbin 151 which is located by another pin 148 carried by the plate 134. The shown housing is in two parts, an upper part containing seven electromagnets and a lower part containing six electromagnets which alternate (when viewed downwardly in the plane of the paper) with the upper electromagnets. Each magnet co-operates with an armature 143 which is faced with a non-magnetic nickel-silver alloy for reducing residual holding flux or deenergization of the magnet. Each armature is carried by prongs at the end of an associated select bar 120 and is forced against a pin 146 on stop-plate 134 by virtue of the spring loading at the remote end of the select bar. A vertical extension 122 (which is in fact forked as depicted in Fig. 21, not shown) at the end of the select bar serves to distribute the select bar spring pressure over a considerable portion of the armature. In another embodiment, Fig. 25, the vertical extension of the select bar is held in contact with that face of the armature which engages the core by means of a spring-clip 172. The extension 170 is apertured, e.g. at 174 to allow the armature to be drawn on to the core 141 when this is energized. The same face of the extension 170 that engages the armature also engages a projection 178 of the stop-plate 176. The select bar 182 is spring-urged 183 at the electromagnet end thereof in this case.
