Abstract: 1,053,823. Bottle cleaning apparatus. H. SILBERZAHN. Feb. 20, 1964 [Feb. 25, 1963; May 17, 1963; Oct. 22, 1963], No. 7126/64. Heading B8T. Apparatus for cleaning bottles comprises a wheel 3, Fig. 1, rotatable about a horizontal axis in a tank 1 containing cleaning liquid, bottle holders 4 mounted non-radially on the wheel and each having a tapered inner portion for receiving a bottle neck, a stationary arcuate retainer 13 which keeps the bottles in their holders whilst they pass through the cleaning liquid, and spray nozzles 6, 7 for rinsing the bottles inside and outside mounted above the cleaning liquid and screened off therefrom. In one embodiment, Fig. 1, the screening is by a trough 5 with a discharge pipe 8. The bottles are inserted into their holders from a sliding carriage 10 by hand or by a pneumatic cylinder 11 and leave the holders under gravity. The wheel 3 is mounted on a shaft 2 rotated intermittently by means of a pedal 12. In a second embodiment, Fig. 7, the shaft 2 carries a disc 15 with holes 16 corresponding to each bottle holder and engageable by a spring-loaded detent. A rocking lever 18 on shaft 2 carries an eccentric which acts to release the detent and allow disc 15 to rotate one step as the lever is rocked by hand or by a jack 23. A jack 32 actuates levers 33, 34, 36, which advance rollers 29 in slots 30 and feed bottles to the wheel. The lever 36 also operates a valve to allow rinsing liquid to pass to spray nozzles 6, 7. Operation of jacks 23 and 32 is by limit switches which control valves in a pneumatic circuit. In a third embodiment, Fig. 16, hoops 57, driven by rollers 58, carry rings 60 and transverse webs 61, on which the bottle holders 4, Fig. 19, are clipped by detents 62, 63. A U-shaped projection 65 on each holder grips a projection 64 on the adjacent one and the holders may be joined by split pins at 70 and 71. The holders comprise tubular members 74, Fig. 23, which direct cleaning liquid from nozzles 77 between the outside of the bottle and the inside of the holder when the bottles are horizontal to remove lables. The nozzles 77 may form an integral structure 78, Fig. 25, fed with cleaning liquid from the tank 1 via a pipe 80 and a built-on tank 81, by a pump 79. The cleaned-off labels are deposited on a perforated drum 82 and discharged into a collecting container 85 by an impeller 83. The nozzles 6, 7 may be stationary, or may rotate with the wheel a short distance and then return rapidly.

Abstract: 1,068,825. Welding by fusion. BRITISH OXYGEN CO. Ltd. Aug. 5, 1964 [Aug. 7, 1963; Feb. 21, 1964], Nos. 31175/63 and 7378/64. Heading B3R. In electroslag or electrogas welding, weld metal is supplied to the melt along a line approximately perpendicular to the surfaces being welded. A strip electrode orientated along the line or a pair of electrodes 5, Fig. 2, spaced along the line or two pairs of electrodes spaced along parallel lines perpendicular to the surfaces being welded may be used. In this way a weld pool 3 shaped as shown, in Fig. 2, is produced and there is a more gradual transition of the directions of grain growth from one side of the weld to the other. Stationary consumable metal electrode guides, which may be coated with insulating slag may be used. The guides may consist of circular tubes (32), Fig. 6 (not shown), which may have flats (35) welded together. The tubes may be of rectangular section, Fig. 7 (not shown), or made of one or more shaped strips 41, Fig. 9, welded to a flat strip 42.

Abstract: 1,124,055. Cash registers; clockwork bells. KASSEN FABRIK EMIL MOGLER. 3 Dec., 1965 [3 Dec., 1964], No. 51494/65. Headings G4T and G5J. [Also in Division E2] A combination lock mechanism, e.g. for the drawer of a cash register comprises a plurality of T-shaped members 8 each mounted on a rocker member 7 which is indirectly actuable by a hand operated lever 4, said members 8 co-operating with a hook-lipped locking bolt 12 which in turn co-operates with a retaining keeper means 27 attached to a fixed part of the cash register. A bell alarm is also provided. As illustrated in Fig. 1, the levers 4 are mounted on a pin 3 underneath drawer grip 2 and actuate rockers 7 via levers 6. The T-shaped members 8 are pivotally mounted whereby they may be set either in their operative position with the T facing the rear of the drawer or in their inoperative position with the T facing the front of the drawer. In the locked position each rocker 7 is held in contact with pin 10. In this position the operative members 8 tilt bolt 12 such that its lip lies behind the hooked edge of the retaining keeper rail 27. When the appropriate levers 4 are operated the rockers 7 are pivoted into contact with pin 11, and the members 8 release the bolt. If a lever 4 is operated corresponding to a member 8 in its inoperative position, this will hold the bolt 12 and thus lock the drawer even if the correct levers 4 are operated at the same time. If an attempt is made to open the drawer while bolt 12 engages retaining member 27, the hinge pin 13 of bolt 12 moves through the length of an elongated hole and in so moving tilts a lever (15), (Fig. 3, not shown), which co-operates with a second lever 16 (Fig. 5) to trigger the alarm. A latch is provided to prevent the return of the hinge pin. Alarm (Figs. 5 and 6B). The automatic winding of the bell spring 35 is effected by a ratchet lever 20 operable by a V-armed winding lever 21 which engages deflector plate 22 when the drawer is closed. In order that the spring is wound only when necessary a sensing lever 25 moves with the spring, its movement being limited by slot 36 in plate 37. When the spring runs down, lever 25 moves sliding bar 39 which causes spring 41 to pull a lever 42 to the right to the position shown in Fig. 6B. The roller 44 carried by lever 42 withdraws from contact with plate 22 and allows lever 21 to contact the plate.

A method of starting and running a compressionignition engine M, Fig. 2 having an exhaust driven turbo-charger 1 including a turbo-compressor set having a turbine distributor and compressor diffusor with variable cross-section, comprises starting the turbo-compressor to operate it independently using a combustion chamber 2 to achieve pressure and temperature conditions for compression ignition, turning the engine and supplying it from the compressor outlet, extinguishing the combustion in the combustion chamber to drive the turbine from the engine exhaust gas whilst controlling the variable distributor or diffusor cross-sections to maintain compression ignition conditions. The turbo-charger is started by a starter 4 and the compressor delivery may be passed through a heat recuperator 3 to extract heat from the turbine exhaust gases and raise the energy level available to a turbine 5 driving a cooling air fan 6. A control valve, responsive to engine coolant temperature may be included in the supply circuit of the fan 6. The turbo-charger may be used to turn the engine M through a mechanical system including an electromagnetic clutch 7. A hydraulic jack (not shown) acts on the turbine distributor to maintain the speed of the turbo-charger set constant and a further hydraulic jack acting on the turbine diffusor may be used to maintain the compressor delivery pressure constant. In another embodiment the clutch 7, heat recuperator 7 and fan 6 are omitted.

The presence or absence of an object at an orifice in the wall of a chamber is sensed by determining the acoustic impedance of the chamber. For sensing a document 22 on a conveyer 25, a standing wave is set up in tube 10 by sound generator 12 but is destroyed when the document covers orifice 16 of the tube. The resulting acoustic loading change at generator 12 produces an electrical impedance change which is sensed by initially-balanced A.C. bridge circuit 28, the unbalance signal being amplified and rectified to trip a threshold circuit 40. Open end 17 of tube 10 prevents accumulation of dirt in the tube, which would cause malfunction of the sensor.
