Title: Means for checking cash registers and the like
IPC: E05B35/08
Filed: 1961-12-12
Abstract: 966,999. Keyholders. M. CARAGE. Dec. 12, 1961 [April 14, 1961], No. 44382/61. Heading A4G. [Also in Divisions E2 and G4] A receptacle for holding the cash from a cash register releases a key, which is used to operate the cash register to print on a slip the grand total standing in the accumulator only when the receptacle is locked. In a first embodiment, the key 1 is retained in slotted brackets 8, 9 by means of a stud on the bolt 11 (Figs. 1, 3, 5). The action of a supervisor in turning a lock 6 by means of a key 25 carries the noses 17, 23 of two bell-cranks 18, 22, connected by a spring 20 and a stud 21 on bell-crank 18 bearing on one arm of bell-crank 22, away from notches 14 to 16 in bolt 11 freeing it so that stud 10 can be moved to retain key 1 in the brackets 8, 9. When key 25 is withdrawn nose 17 engages notch 16 and nose 23, notch 14. When the cash has been transferred, the keeper is swung anticlockwise, locking the cashbag, releasing nose 23 and causing nose 17 to engage notch 15. The key 1 can now be removed and used to operate the cash register. Beneath the key location is an orifice 26 into which the printed total slip is to be inserted. The key 1 is then replaced in the brackets 8, 9 and the keeper extracted slightly. The bellcranks 18, 22 then both engage the central notch 16 positively, locking the keeper in a position in which both the cash receptacle and the key 2 are -locked. In another embodiment, Fig. 10 (not shown), a straight bolt is operated by a rack successively to unlock and lock compartments, one of which receives the key 1, on each side of the lock mechanism, in the final position locking both compartments. In Fig. 11 (not shown), a straight bolt is linked to another bolt operating in a parallel direction to lock compartments of a handbag or the sliders of a pair of sliding clasp fasteners. In a final embodiment two compartments 47, 48 are closed by a single sliding lid 46, studs 60 engaging slots in side flanges of the lid and limiting so that both compartments are not uncovered at the same time. When the key compartment 47 is uncovered a spring cylinder lock is released which prevents the cash compartment being uncovered thereafter. When the key and cash slip are returned to the compartment 47, the lid 46 is secured by engagement of a flange 61 with a spring catch 63 on the lock cylinders (Fig. 18). The lock (Fig. 13) has a cylinder 51 which can be depressed into its casing against a spring (not shown) when a key 50 is inserted so that the surfaces of contact of pairs of pin tumblers 53 are aligned with the boundary of the cylinder and its casing. The lock is kept depressed by the lid until compartment 47 has to be uncovered. The lower part of the casing 52 has a sprung wall so that the key can be removed.

Abstract: 1278889 Gas turbine jet engine - select combustion control MOTOREN-UND TURBINENUNION MUNCHEN GmbH 18 Sept 1970 [11 April 1970] 44691/7C Heading F1J A gas turbine jet engine is provided with an afterburner also with a variable area jet nozzle, the engine having control apparatus which is effective to vary the area of the jet nozzle as desired, also fuel control means responsive to a signal from the nozzle actuating device to increase or decrease the fuel supplied to the afterburner in dependence on the actual area of the nozzle. The engine shown comprises a jet pipe 7 in which is disposed afterburner equipment comprising fuel manifolds 23, 24, 25 and flame stabilizing gutters 26, 27, 28. A variable area nozzle comprising pivoted flaps 10 is mounted at the downstream end of the jet pipe. The engine is controlled by a throttle lever 11 which controls supply of fuel to the engine combustion equipment 3, 4 through a fuel control unit 13. When the throttle is moved beyond the position a for example to the positions 21 or 22 a signal is transmitted through line 33<SP>1</SP> and electronic control unit 34<SP>1</SP> and lines 35, 36 to nozzle actuator 37 which acts through linkage 38 to open the jet nozzle 10. Simultaneously a signal is transmitted from actuator 37 through lines 39, 40, 41 to afterburner fuel control unit 32 which controls supply of fuel to afterburner 23, 24, 25 in dependence on the actual area of the jet nozzle. A signal dependent on certain engine parameters is supplied through lines 43, 44 to a further control unit 45 which acts to vary the nozzle area in the event of any difference between the nominal and actual values of one or several engine parameters, a signal passing from control unit through line 46 to summation point 47 in line 35, 36. A signal from line 43 is also passed to afterburner fuel control unit 32. When throttle lever 11 is moved to afterburner range, fuel is injected through burners 48, 49 in the main combustion equipment so as to cause an afterburner ignition flame which is sensed and a signal passed through line 52 to control unit 34<SP>1</SP> which acts to unlock the nozzle actuator 37. In the event of afterburner flameout the signal in line 52 is cancelled and the nozzle is restored to its minimum area position.

Title: Improvements in or relating to thermoelectric arrangements
IPC: H01L35/08
Filed: 1962-12-03
Abstract: 1,014,546. Thermo-electric devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 3, 1962 [Dec. 6, 1961], No. 45614/62. Heading H1K. In a method of manufacturing a thermoelectric arrangement comprising the series connection of thermo-electric elements which alternately consist of different semi-conductor materials with the interposition of contact members between elements, prior to the assembly of the elements and contact members a layer of insulating material is applied to the entire lateral surface area of each element. The elements may be cut from bars of semiconductor material. The insulating layer may be applied to the bar before subdivision, or may be applied separately to the individual elements. The layer may be formed by laquering with, for example, a silicone-based laquer or by gluing on or shrinking on a resin sleeve. Apart from their insulating function, the layers may serve to prevent poisoning of people handling the elements, to protect the elements from atmospheric contaminants, to prevent areas of the elements from being wetted by solder during drip-coating processes, in assembly to indicate solder-free faces or the orientation of the element, or they may serve for example by colour coding to identify the nature and type of element. The Specification outlines dipcoating methods in which either one end of an element or an entire element is immersed in a bath of liquid tin solder to coat one or both end faces with solder. As described with reference to Figs. 9 and 10 a series of insulated P- and N-type elements are soldered to a copper bar 16 and their end faces 11 coated with solder by dip-coating in liquid solder 13. A second copper bar 18 is then soldered to these faces. The two copper bars are then severed to provide alternate series connection of the P and N elements. The assembly is then embedded in insulating material to increase its mechanical strength. It is used as a Peltier cooler.
