Abstract: 1516537 Semiconductor switching circuits RCA CORPORATION 26 Aug 1975 [3 Sept 1974] 35176/75 Heading H3T In a switching circuit comprising a first device Q 1 A arranged to respond to an input signal V 1 and to switch current into a load RL for the duration of said input signal V1, the turn-off time of QIA is reduced by a feedback path from the output electrode of QIA to the signal input via a charge storage device such as capacitor C1 and a further switching device Q2, turned on momentarily when the main device Q 1A is to be turned off. As shown, the main switching device may include a reciprocally coupled complementary pair of transistors Q1A, Q1B which are both turned on for the duration of the input pulse V1. At the end of V1, transistor Q2 is turned on by the differentiated trailing edge of V1 so that the charge stored in C1 helps to turn off Q1A and hence Q1B. During repetitive operation, the voltage at Y is equal to twice the supply voltage at terminal 10. In Fig. 1 (not shown) Q1B is omitted. In Fig. 2 (not shown) an inductor is included in series with C1 and clamping diodes are connected to Y and to the base of Q1A. In Fig. 3 (not shown) Q2 is replaced by a reciprocally coupled complementary pair of transistors. Fig. 6 (not shown) depicts a four-layer silicon controlled switch having loads in series with the anode and cathode, a first capacitor connected via a first switching device between the anode and a first gate layer and a second capacitor in series with the second switching device connected between the cathode and a second gate layer.

Abstract: 1,236,909. Spray-producers. MONTECATINI EDISON S.p.A. 15 July, 1969 [15 July, 1968; 24 April, 1969], No. 35654/69. Heading B2F. [Also in Divisions A5, C4 and C5] Fires are extinguished by ejecting on to the fire symmetrical dibromotetrafluoroethane under a pressure of from 4 to 20 atmospheres through a spray nozzle having an internal bore substantially in the shape of a truncated cone with a conical angle from 4‹ to 20‹ the cone converging in the direction towards the outlet orifice of the nozzle. (The "conical angle" is one-half the flare angle of the cone.) The outlet orifice may be circular, or elliptical in which the ratio of the major axis to the minor axis of the ellipse is between 5:1 and 1:1. The dibromotetrafluoroethane may be pressurized by a mechanical pump or through the use of a gaseous propellant, exemplified by: (1) nitrogen, helium or air (insoluble in the dibromotetrafluoroethane); (2) carbon dioxide (partially soluble); and (3) halogenated hydrocarbons such as CF 2 Cl 2 , CHClF 2 , CBrF 3  or CF 4  (completely soluble). According to one of many examples, 180 Kg of dibromotetrafluoroethane was loaded into a 100 litre tank of a wheeled extinguisher and this was then pressurized at room temperature with nitrogen. The combustion of a benzene - gas oil mixture was extinguished by the ejection of about 1 kg of the dibromotetrafluoroethane through a nozzle having an orifice of elliptical shape and a conicity of 8‹ and 6‹. The area of the orifice surface amounted to 20 mm<SP>2</SP> and the ratio of the major/minor half axes was 3:2. Other combustible materials are detailed.

Title: Improvements relating to automatic feeds for machine tools
IPC: B23Q35/06
Filed: 1956-11-22
Abstract: 813,207. Lathes. WARNER & SWASEY CO. Nov. 22,1956 [Dec. 13,1955], No. 35725/56. Addition to 783,151. Class 83 (3). The automatic positioning arrangement for the transverse location of the tool, to machine a progressively-stepped workpiece, as in the parent Specification, is modified, as regards the spring motive means and the transmission from the movable control element to the tool-rest. The latter may have a pivoted tool-holder 117, Fig. 2, or a sliding holder 244, Fig. 9. In each embodiment the tool-holder is connected to a rack-bar 121, Fig. 4, loaded by a compression spring 126, Fig. 2, which is compressed when the tool T is in its inner position, the tool moving outwardly, urged by this and a second spring, in steps as the control element (see below) is released. The rack-bar 121 engages a pinion 138, Fig. 4, at the lower end of a vertical spindle 139, the upper end carrying a gear 145 engaging another rack-bar 157 which is loaded with the second compression spring 159, Fig. 2. An internal-gear 153 is secured to the gear 145 and is engaged by a pinion 178, Fig. 4, secured to a short vertical-spindle 177. The upper end of this spindle carries a worm wheel 180 engaged by a worm (Fig. 5, not shown), on a shaft carried by the control element 170. The worm-shaft may be clamped by a hand-knob 194, Fig. 2, to prevent relative rotation between the worm and wheel. The control element, in this condition, when allowed to rotate, also controls the tool movement outwardly to a new turning-diameter position. When the worm-spindle is unclamped the relative positions between control element and tool-cutting diameter may be adjusted. The outside of the control element 170 is recessed to take a series of control rings 206-209, Fig. 2, and these are each provided with an external notch 218, Fig. 3. A series of spring-pressed pawls, corresponding to the control rings and arranged adjacent the control-element head on the same supporting bracket 110, Fig. 1, slide against the rings until the first pawl in the series engages one of the notches 218, Fig. 3. The control element is arrested and the tool starts its traverse at this pre-set diameter. As the toolcarriage E moves longitudinally for the cutting- traverse, the control-element moves past a rail 235 carrying pre-adjusted stop-members 233, which lie in the path of the roller-equipped ends 231, Fig. 3, of the pawls. The firstengaging pawl is thus lifted by a stop such as 233 and the control-element is released, turning under spring pressure to a new position when the second pawl in the series engages the second ring notch. The tool is thus adjusted automatically to a new and larger diameter.

Abstract: 1470180 Programmable electronic calculators HEWLETT PACKARD CO 14 Aug 1974 [30 Aug 1973] 35806/74 Heading G4A A programmable electronic calculator 10 comprises a keyboard 12 having 35 keys, including 9 digit keys and 26 non-numeric keys, each key being assigned a unique six-bit key code by a keyboard encoder 14, the key code of an actuated key being held in a read-write memory buffer (RWM buffer) 16 and establishing an address in a read-only memory (ROM) 20, holding a display microinstruction to which a central processing unit (CPU) 24 refers. When a program is being entered, the CPU 24, under control of the ROM 20, instructs the RWM buffer 16 to insert the key codes into a read-write memory (RWM) 18. The results of a calculation are decoded by a display decoder 26 coupled to a LED output display 28. The keyboard 12 includes a singlestep key, (SST), Fig. 1 (not shown), actuation of which causes the decoded key code of the last actuated key to be shown on the output display 28. The displayed key codes are as follows:- (a) for a digit key k, the displayed key code is the two-digit number 0k; (b) for a non-numeric key in row r (counting from the top of the keyboard) and position s along that row counting from the left, the displayed key code is the twodigit number rs. (No key code is displayed for the (SST) key.) A modification is described wherein the key code association of type (b) above is applied to all the keys. The calculator is operable in either of two modes by means of a program-run switch 22, programs being entered in the "program" mode. In this mode, actuation of the (SST) key causes the CPU 24 to interrogate the RWM buffer 16 for the address of the corresponding display instruction, in ROM 20, of the last key depressed; successive actuation of the (SST) key causes the RWM buffer 16 to retrieve the key codes of previously actuated keys from the RWM 18, enabling the use of an "edit" mode to correct or modify program instructions. In the "run" mode, the key codes are not transferred to the RWM 18 from the RWM buffer 16, but the key code of the last actuated key may still be displayed by setting the program-run switch 22 to "program" and actuating the (SST) key, since that key code is stored in the RWM buffer 16, In a modification, the calculator may have more than 35 keys, each key having assigned to it a unique key code.
