Title: Improvements in and relating to machines for making frozen confections
IPC: A23G9/26
Filed: 1963-11-08
Abstract: 1,106,622. Frozen confections. A. C. BILLINGHAM. 5 Nov., 1964 [8 Nov., 1963], No. 44087/63. Heading A2B. [Also in Divisions B8 and F4] Apparatus for making ice-confection comprises a mould-carrying conveyer 2, a second conveyer 5 for transporting vertically movable stick-engaging devices 6 and a common mechanical drive for synchronously advancing the conveyer in a step-wise manner and for raising and lowering the stick-engaging devices when the conveyers are stationary. The drive comprises a motor 14 which drives a shaft 15 via reduction gearing 16, a first cam 20 which drives conveyer 2 via a toothed wheel 23 and a second cam 21 which is arranged to reciprocate a rod 29 carrying a defrosting tank 36 and a rack 30. The conveyers are linked by a drive and rack 30 engages a pinion 31 which is linked to a second pinion 32. Pinion 31 engages a rack 34 which effects vertical movement of the stick-engaging means while pinion 32 engages a rack 35 which effects movement of the confection into and out of a chocolate-coating bath 12. The coated confections are subsequently dropped into a bagging device. A mould-filling device (Figs. 4a, b, c and 5a, b, not shown) is provided above the opposite end of conveyer 2 and comprises a supply tank and a plurality of depending cups which fill and discharge under the control of valves actuated by a pneumatic device. The latter is controlled by one of a plurality of cams 22 mounted on shaft 15. After being filled, the moulds are lowered into a freezing tank (Fig. 10, not shown) in which cooled brine from a perforated supply pipe (71) rises through the perforated bottom (70) of an inner tank and is extracted for further cooling from between the walls of the inner and outer tanks. While the moulds are in the tank sticks are inserted in the partially frozen confection, the stick-inserting device (Figs. 11 to 14, not shown) being mounted for limited horizontal movement above the conveyer and comprising a sloping channel (72) containing a plurality of upright sticks. A pneumatic device (76) controlled by one of cams 22 reciprocates a blade (75) which forces the lowermost stick in the channel into the mould on its downward stroke.

Title: Improvements in or relating to the clearing of minefields
Inventor: STEGBECK WERNER
IPC: F41H11/14
Filed: 1960-12-24
Abstract: 924,634. Clearing of minefields. COMET-APPARATEBAU G.m.b.H. Dec. 24, 1960, No. 44380/60. Class 9 (2). A line 10 is fired across a minefield by means of a rocket 12 from a launcher 13, after which explosive charges 11 spaced along the line are exploded by the detonator at the free end of the line. To prevent snarling as the line runs out, it is mounted on a backing in a container 14 to which it is anchored at one end. The striker 15 is rendered safe by a spring hook 16 which imposes a time delay to allow the line to reach the ground before detonation. The charges 11 are so spaced that their spheres of action intersect, and therefore mines lying between the charges are exploded. In a modification a plurality of explosive charges 11 is arranged in staggered rows on lines such as 10 mounted on a backing strip. Extensible members such as helical springs or telescopic tubes may be placed between the network of charges and the anchoring means 14.

Abstract: 1,132,467. Determining the position of a web photo-electrically. GPE CONTROLS Inc. Oct.22, 1965 [Dec. 17, 1964], No.44745/65. Heading G1A. The centreline position of a longitudinallytrowelling, light-impervious web is determined by means of a light source positioned transversely across one face of the web to project a beam which partially passes outside each lateral edge of the web to impinge upon first and second elongated arrays of photo-voltaic devices positioned transversely adjacent each web edge on the side opposite the light source, the cells of the respective arrays being connected in parallel and each across a respective impedance, to provide an output in accordance with their voltage difference. The arrangement may include a switch whereby the position is determined by one photo-voltaic device, and a reference voltage. The lamps in the two devices may be connected in pairs in series, with one in each pair forming part of its respective source, so that the sources remain balanced in the event of a single bulb failure. The construction of a sensor in which a number of cells, which may be silicon p-n junction devices, are mounted adjacent each other on an aluminium base to make a two-foot length of sensor is described. The source and sensor may include elongated obstructive slits and the relative widths of the slits is discussed. Diffusing means may be employed to provide uniform light intensity, and the intensity may be such as easily to saturate the cells. The photo-sensor devices may be fixed, manually adjustable, or automatically positionable in relation to the edges by a servo-mechanism, and the cell output may control a web positioning servo.

Filed: 1972-10-05
Abstract: 1393017 Label printing apparatus T H CLARK 26 Sept 1973 [5 Oct 1972] 46005/72 Heading B6C Labels 64 on a roll 66 are printed in a machine in which the printing head rocks such that the curved part of the impression member rolls over a likewise curved part of the head carrying the printing plate. The head oscillates about its longitudinal axle, the movement of the head during its non-printing stroke being under the action of a spring. In the machine shown hand operated rotation of the impression member 58 causes the clockwise movement of the head 14 so that the curved flexible printing plate supported therebeneath prints a label 64 using the contacting carbon ribbon 72 for image media. The plate is readily released from the head 14 by swinging an arm 30 which, firstly, causes the head to move to its "printing start" position and, secondly moves apart spring-loaded lips 18 and 20 thus releasing the plate. Spacer members 78, 62 are carried by the head and the impression member to ensure correct printing.

In Fig. 3, a third coil 9 is fed with the incoming signals, a temperature variable resistance R2cu being located in the voltage supply circuit. In a further modification, the coil 9 is connected between temperature constant and temperature variable resistances, the constant part being a shunt on the third coil.
