Title: Arrangement for transforming electrical energy
IPC: H02M7/62
Filed: 1934-05-31
Abstract: 443,882. Commutator switching arrangements. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. May 31, 1934, No. 16301. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 1, 1934]. [Class 38 (ii)] In an arrangement for generating oscillations in which a source of D.C. is connected periodically through an interrupter K to a transformer Tr which is tuned by a condenser C connected in parallel with its primary or secondary windings, the circuit is tuned so that when the contacts of the interrupter are closed the voltage across the condenser, referred to the primary side of the transformer, is equal in magnitude and sign to the voltage of the D.C. source. The circuit may be tuned so that the contacts re-close the first, or second or other occasion on which the said voltages are equal. The Specification includes a theoretical discussion of the optimum conditions of frequency, periods of contact closure, &c. The interrupter may be of the electromagnetic type, the contact and magnet winding being in series with the transformer primary, and the condenser being connected across the secondary winding. Alternatively, the transformer primary itself may constitute the winding of the interrupter and the condenser is connected in series with a resistance across the primary winding. Such an arrangement may provide buzzer current in a telephone system as shown in Fig. 9 in which the transformer primary acts as the interrupter winding and its armature 10 is connected to the supply through a winding of a relay RL and contacts 15, 16 controlled thereby. Two further windings on the relay RL are connected through wiper contacts RV to the telephone set H and to the supply. The arrangement is such that when the telephone set has been connected to a free register which has been found by the register finder RV, contacts RV are closed and the relay RL is energized thereby energizing the interrupter Tr. The secondary S of the interrupter transformer Tr is coupled to the lead from the armature to the relay winding RL by a condenser C1 so that the buzzer current is passed into the telephone set by transformer action between the windings on the relay RL. The interrupter and transformer may be of the double acting type in which the condenser C is connected across the whole of the primary winding which is centre tapped and connected through a battery to the centre armature of a switch which oscillates between two contacts connected one to each end of the transformer primary.

Abstract: 1421212 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 April 1973 [8 April 19.72] 16310/73 Heading H1K In a method of making, for example, integrated circuits in which inset regions of silicon oxide are formed in a monocrystalline silicon wafer by oxidation through apertures in a layer of masking material a layer of polycrystalli ne silicon is provided between the masking and the wafer surface. As described an isolated transistor is formed in a 3 ohm cm. P-type silicon wafer by diffusing boron and arsenic respectively into one face at the desired locations of the isolation regions and an N+ subcollector, depositing a 4 Á epitaxial layer of N type 1À5 ohm cm silicon and a 0À1 Á layer of polycrystalline silicon from silane at 1050‹ and 700‹ C. respectively and then depositing a masking layer of silicon nitride 0À1-0À2 Á thick by reaction of silane and ammonia at 1050‹C. After etching grooves through the nitride into the silicon to a depth of Á the wafer is heated at 1000‹ C. in water saturated nitrogen to fill the grooves with oxide and out-diffuse the boron and arsenic to reach the oxide. After removing the nitride and optionally the polycrystalline silicon the surface is oxidized and the base zone 15 (Fig. 9) formed in island 123 by diffusion of boron while island 122 is masked with photoresist. The oxide exposed via photoresist mask 152, 153 is etched away and after removal of the mask phosphorus is diffused in to form an emitter zone within the base zone and a collector contact region 163 (Fig. 11) in island 122. Contact windows are then formed over the ease and emitter zones and region 163 exposed and aluminium vapour deposited overall and etched back to form the electrodes shown.

Title: Improvements in or relating to clutch devices
IPC: F16D11/06
Filed: 1960-05-09
Abstract: 929,637. Clutch control. COMPAGNIE DES MACHINES BULL. May 9, 1960 [May 22, 1959], No. 16322/60. Class 80 (2). A one-revolution clutch, particularly for use in record-card machines, comprises a driving sleeve 45 having an abutment surface 46 drivingly engaging a pawl 68 pivoted on a driven member 53 and an abutment surface 47 engaging a counter-pawl 69 to prevent rebound of the driven member. At the end of one revolution, if an electromagnet 124 is not energized, an end of an abutment lever 98 engages an arm 77 of a retraction lever 72 which is pivoted about 63 to disengage the pawls from the driving sleeve. A stop 54 on the driven member 53 then engages the end of the lever 98 and a counter abutment lever 115 bears with a ledge 118 against the back of the stop 54 so that the driven member is prevented from rotating in either direction. The shock of stopping the driven member is absorbed by the abutment lever 98 which is provided with a pin 99 urged to one end of slots 100 in a supporting means by a spring 102 which also biases the abutment lever 98 in a clockwise direction. The shock is damped by displacement of the pin 99 against the spring pressure. To engage the clutch an electric impulse is applied to the electromagnet, the armature 127 of which is thereby withdrawn from the path of a tripping lever 104 and allows a cam follower 111 which is supported by a lever 110, to enter a recess of a cam 43 which is fast with the driving sleeve 45. The cam follower supporting lever 110 is fast with the tripping lever 104 and is biased towards the cam by the spring 102 acting by way of co-operating arms 97, 103 on the abutment and tripping levers 98, 104. When the follower enters the recess the abutment lever 98 is pivoted clockwise by the spring, releasing the lever 72 so that the pawls are released and engage the abutments of the driving sleeve 45 under the influence of a spring 70. The electromagnet is de-energized at the end of the impulse and during the course of a revolution of sleeve 45 the cam 43 returns the levers 98, 104, 115 to their stop positions so that, unless the electromagnet receives another impulse, the driven member 53 is arrested after one revolution as the armature 127 blocks anticlockwise movement of the lever 104 and consequently prevents the follower 111 from entering the cam recess. The supporting means for the electromagnet and levers 98, 104, 115 is adjustable with respect to the clutch housing so that the angular locking position of the driven member 53 can be adjusted.
