Abstract: 316,623. Konemann, H. Aug. 1, 1928, [Convention date]. Optical apparatus.- In the photographic copying of a combined picture and sound film provision is made for illuminating the records on the negative film differentially during the simultaneous printing. To effect this, a single lamp d, Fig. 5, in a casing, directs light on to a single, aperture f in a film guide for the negative and positive films a, b, and the parts of the aperture opposite to the picture and sound records respectively are adjustable separately by sliding shutters controlled by handles o, n, or the shutter for the picture portion may be omitted. The Specification as open to inspection under Sect. 91 (3) (a) states that the differential printing can be effected by adjusting a single source of illumination so as to be nearer to one record than the other by the interpolation of damping screens of semi-transparent material; by variation of the size of the exposure apertures, or by using two separate sources of illumination for the two records, and shows in Fig. 6 (Cancelled), separate lamps d<1>, d2 for the picture and sound records in addition to the adjustable shutters h, i controlled by handles o, n, the two lamps being adjustably mounted in separate compartments of a light tight box which may also have semi-transparent screens r1, r2 to regulate the light. This subject-matter does not appear in the Specification as accepted.

Title: Multi-emitter transistors and circuit arrangements incorporating same
Inventor: THOMPSON PHILIP MARTIN
IPC: H03K3/288
Filed: 1963-06-18
Abstract: 1,082,519. Multi emitter transistor circuits. PLESSEY U.K. Ltd. May 28, 1964 [June 18, 1963; July 5, 1963], Nos. 24129/63 and 26718/63. Heading H3T. [Also in Division H1] A multi-emitter transistor uses one emitter in the normal forward conduction mode and one or more others in a reverse bias mode to couple an input to the base. The coupling may be capacitive or by Zener conduction. Fig. 4 shows a comparator in which the first transistor J 1  has its base potential clamped by a Zener diode formed by the right-hand emitter-base junction. The transistor becomes conducting when a negative voltage is applied to the lefthand emitter which operates in the normal manner. Transistors J 2 , J 3  have their normal emitters commoned, the other emitters operating as Zener diodes to provide a coupling to the bases. One or other of the two transistors conducts depending on the value of the input voltage on the reverse conducting emitter of the left-hand transistor with reference to the voltage on the reverse conducting emitter of the right-hand transistor. Further inputs may be applied to additional reversely conducting emitters such as A. Fig. 5 (not shown) is a bi-stable circuit in which the collector to base cross-coupling is effected through Zener diodes formed from emitter-base junctions. Set and reset pulses are applied to the bases of transistors (J4 and J7) connected in parallel with the main transistors, to reduce the collector voltage of the non-conducting transistor to zero. The charge stored in the coupling Zener diode at the other transistor is used partly to switch off the transistor, the rest being held until the end of the trigger period to ensure that the previously conducting transistor is held non- conducting while current builds up in the other. Fig. 8 shows a logic circuit in which the emitters on the same side as the base connection operate as Zener diode couplings to the base to provide an OR input and the conventional diodes B provide an AND connection between the stages. Fan-out is provided by diodes T and further logic by inputs C and D. The transistors may also be used in an amplifier (Figs. 6 and 7, not shown) in which case a reversed biased emitter junction (Ex) serves either as a Zener diode coupling to the base from the previous collector or as a capacitor in shunt with a resistive connection (Rc) to the base. The circuits may be assembled on a single chip of material, and when the reversed biased emitter is used as a capacitor it may be of the large area type.

Abstract: 1,037,804. Solid state devices. SIEMENSSCHUCKERTWERKE A.G. June 18, 1963 [June 19, 1962], No. 24156/63. Heading H1K. In a series PNPN structure the shortest distance, as measured on the surface of the semi-conductor body, between an end zone and the junction between the next two zones is at least 20 times as great as the diffusion length, at the surface of the body, of the minority carriers in the zone adacent the said end-zone. In one embodiment (Fig. 1) a disc of N-type silicon 2 is subjected to surface diffusion of aluminium to produce a P-type zone, and by etching or mechanical grinding a pit 5 is formed which subdivides this zone into two regions 3 and 4. The diffusion process and etch procedures are described in detail in the Specification. An aluminium foil 6 alloyed to the region 3 provides an electrode therefor and a goldantimony annular disc alloyed to the zone 4 provides a further N-type zone 7 and also electrode 8. A further foil 9 containing gold and boron is added to the assembly and provides a further electrode; the assembly is then heated to about 800‹ C. in a furnace. In a further embodiment (Fig. 2, not shown) after the aluminium diffusion step the whole disc is provided with a silicon oxide layer and a ring- shaped region thereof on the body surface is subsequently removed. A boron diffusion is then effected in this oxide free region to reduce the diffusion length of the minority carriers in the surface layer of the zone 4.

Patent GB-242810-A (GB)
Abstract: 242,810. Eller, F. Dec. 22, 1924. Tickets, issuing and cutting off; printing arrangements.-A ticket printing and issuing machine comprises a number of similar sections 5 adapted to be actuated by a common powerdriven shaft 6, and arranged out of reach of the operator, by whom they are controlled, through push buttons 11. The buttons are connected by Bowden cables 31 to pivoted release levers 30 which control the actuation of feed rollers 46, 47, printing rollers 48, 49, severing mechanism 44, 44<1> and a counter 53 in each faction. The severed tickets are guided to the operator's table 2 by shoots 13. Continued depression of a button 11 results in sevaral tickets of one kind being issued. When the supply of paper 57 on the roll 15 in a section is exhausted, a spring pressed feeler 58 is rocked on its pivot 59 and rocks a lever 61 into the path of one end of a lever 26, and so locks the section against further actuation. The strip feeding and printing rollers are geared by a pinion 45 to a pinion secured to a cam 18 which is clutched to the constantly revolving shaft 6, when the lever 30 is rocked, by a spring-pressed pawl 21 pivoted on a pin 22 on the cam. The pawl is normally held out of action by a nose 26<2> on a spring-pressed lever 26 pivoted at 29 this lever being held by the engagement of its tail 26<3> with one arm 30<1> of the lever 30. Upon the lever 30 being rocked by the Bowden wire 31, the lever 26 is released, and the cam 18 is clutched to the shaft 6. The reciprocating cutter 44 is then actuated by a pivoted lever 33 which has a roller engaging a cam-groove 38, thus severing a previously printed ticket. The feeding portions of rollers 46, 47, and the printing rollers 48, 49 then become effective, mechanism 51 being provided to print a serial number. If the push button has been released, the lever 26 is reset after one revolution by the engagement of a roller 26<1> with the cam edge 73. The counter 53 is driven from the feed roller 47, and the inking device 55 from the roller 49. Backward rotation of the cam 18 is prevented by a pawl 39.
