Title: Apparatus for the simultaneous maí¡í¡ an filling of packages
IPC: B65B3/02
Filed: 1957-07-04
Abstract: 835,610. Packaging machines. DECKERS, J. July 4, 1957 [July 20, 1956; Oct. 30, 1956], No. 21226/57. Class 94(1). A machine for packaging fluent material in plastic containers extrudes a tube of plastic which is closed at the free end by sealing and cutting off a previously formed container, the tube being cooled and then filled by a conduit movable within it prior to being separated from the next tube portion to be filled. Heated material is extruded through an annular opening 5 into a container 8 through which water circulates via conduits 22, 25. Extrusion may be facilitated by gas passed through a pipe 2. The material being packaged is fed from a conduit 3 which descends into the tube and then rises with the level of the material. The supply of contents is controlled by photoelectric means 16, 21 operated by the sealed end of the extruded tube. When filling is complete, elements 6, 7 seal and separate the package which falls on to a conveyer 24 operating beneath the water level A-A. The packages are discharged on to a conveyer 26 for drying by infra-red means 27 and on to a conveyer 28 for printing, and are finally collected in a box, &c. 30.

The catalytic material may be applied in powder form to a body from which the surface skin has been removed; or it may be incorporated in the material prior to forming the body, the formed body being prepared by sanding, blasting, brushing, tumbling or chemical etching; or it may be forced into the surface whilst simultaneously freshening the latter, eg. by wet or dry heating, buffing, tumbling, sanding or wire brushing using a mixture of abrasives and catalyst or using the latter also as the abrasive.  The catalyzed surface may be subjected to spray washing with a detergent or to vapour degreasing prior to immersion in the plating bath.  In a further alternative, the body, after surface freshening, is immersed in a solution of the chloride, nitrate, bromide or sulphate of palladium, rinsed with water, immersed in a solution of a reducing agent such as hypophosphorous acid, hydrazine hydrochloride or hydroquinone and again rinsed prior to immersion in the plating solution.

Title: Improvements in and relating to brakes for controlling rotary motion
Inventor: TAIT JOHN NOEL HUTTON
IPC: F16D49/08
Filed: 1954-07-24
Abstract: 777,726. Band brakes. BIRMINGHAM SMALL ARMS CO., Ltd. Dec. 15, 1955 [July 24, 1954], No. 21684/54. Class 103 (1). In order to provide substantially equal braking power in both directions of torque application in a flexible brake band system used in conjunction with an epicyclic driving gear in which two secondary brake bands are arranged within a primary brake band element, one secondary band having an anchorage independent of that on the primary band, the lining associated with the secondary band elements are disposed substantially equally in relation to the anchorage or reaction points of the elements, the linings being so fixed to the elements that gaps between the adjacent ends are disposed substantially diammetrically opposite the respective anchorage points. In the embodiment illustrated, the primary brake band 1 is anchored at 11 and is provided with a projection 13 for attachment of an operating lever (not shown). Within the brake band 1 are two secondary brake bands 3 and 9 each provided with a friction lining 7, 5 respectively and arranged to operate on a brake drum (not shown) which is provided with circumferential grooves of about 55 degrees included angle to increase the friction hold of the brake lining by a wedging action. The secondary brake band 9 is secured at one end to the primary band 1 such that the gap between the ends of the band 9 is diammetrically opposite to the gap between the ends of brake band 1. The secondary brake band 3 is arranged side by side with band 9 and is arranged so that the gap between its ends is diammetrically opposite to the gap between ends of bands 9, the anchorage point 15 in lug 3a of band 3 being opposite anchorage point 11 of band 1. In operation the frictional hold applied by the brake will be approximately equal in either direction of rotation of the drum since in any circumstance approximately half of the length of each brake element will tend to wrap on and half to unwrap. Specification 220,021, is referred to.

Switches 45-49 accessible as tabs, Fig. 2 (not shown), may provide single pulses to activate any of the percussive circuits. The clock oscillator frequency is increased for the march rhythm by disconnecting capacitor (71), Fig. 13A (not shown) from the oscillator circuit, and a tempo lamp, Fig. 13A gives visual indication of the tempo pulses. The frequency dividers 51-53 are gated via a foot switch to initiate any tempo sequence, and the tempo is adjustable. All frequency dividers are of J-K flip-flop configuration, two on each integrated circuit. The audio circuitry is on a single circuit board, Fig. 12B (not shown), and another circuit board, Fig. 13B (not shown), supports the logic circuits. The audio circuits may feed the organ amplifier and speaker (21, 22) Fig. 3 (not shown), or have their own amplifier and speaker.
