Abstract: 1,252,570. Laminates. NEPTUNE MICROFLOC Inc. 24 Dec., 1968 [15 April, 1968], No. 61313/68. Heading B5N. [Also in Divisions B1-B2 and C1] A baffle construction unit made of plastics (exemplified), plywood or metal and used as packing in a cooling tower or contact filter or in settling tank for sewage or water treatment, comprises vertical parallel sheets 22 and transverse, inclined baffles 24 dividing the space between each pair of sheets into parallel passages, the passages between adjacent pairs of sheets being relatively inclined. In Fig. 2, sheets and baffles are initially separate, but in Fig. 9 (not shown) a similar construction is made by joining a number of square-sectioned tubes, and in Fig. 10 (not shown) the basic unit is a sheet with integral baffles, formed by extrusion. Fig. 1 (not shown) represents a complete baffle construction unit with 16 sheets 22 and end recesses (52) to accommodate suspension supports (Fig. 4, not shown). In use in an annular settling tank (Figs. 3, 5, not shown), spaced radially extending units (20a) support groups of circumferentially extending units (20b), and sewage flows upwards through the passages 26, liquid overflowing at outer rim (12) and solids settling to sump (15). In Fig. 6 (not shown) groups of units are supported between pairs of radial straps. Alternatively parallel units could be used in a rectangular tank.

A golf ball consists of a solid centre of moulded elastomeric material covered with a thin winding of thread of elastomeric material, both materials preferably being natural or synthetic rubber. A one piece, seamless cover is injection moulded over the centre, this cover being an ionomer resin, i.e. a copolymer of a major proportion of an α-olefin with an α, /3-ethylenically unsaturated carboxylic acid having preferably 3 to 8 carbon atoms, the copolymer having from 10% to 90% by weight of the acid groups ionized by neutralization by metal ions. A preferred α-olefin is ethylene. Titanium dioxide may be incorporated. in the resin to improve the whiteness of the cover and eliminate the use of paint. Alternatively the cover can be painted, in which case it is etched to help the coat of polyurethane paint adhere to it.

Abstract: 1,258,904. Machinery guards. CRAWFORD, HANSFORD & KIMBER Ltd. 20 June, 1969 [21 March, 1968], No. 13724/68. Heading F2J. A press brake has a safety guard system comprising a floor mat arranged to surround the parts of the machine accessible to an operator, the mat incorporating pressure sensitive switch means, and a control switch accessible to an operator from beyond the periphery of the mat, the arrangement being such that, with the machine tool in a dangerous condition, actuation of the pressure switch means renders the machine inoperative, whilst operation of the control switch returns the machine tool to a safe condition and renders the pressure sensitive switch means ineffective. The mat assembly may comprise a steel plate provided with a rubber surface and located within a bevelled frame, the plate being upwardly spring-loaded into an idle position from which it can be depressed under the weight of an operator to actuate a switch located below the plate. A foot switch for initiating the working stroke of the press brake may be located at the inner periphery of the mat, adjacent the machine. An isolating switch may be coupled to two spaced backstops of the machine in order to isolate the foot switch unless a workpiece is pressed firmly into contact with both backstops. Alternatively initiation of the working stroke may be effected by contact of the workpiece with the backstops. Adjustable means are provided for limiting the maximum throat opening.

Abstract: 1,266,951. Pointing. GEORGE A. MITCHELL CO. 28 Feb., 1969 [3 Oct., 1968], No. 5295/69. Heading B3P. A tube or bar is pointed to allow subsequent drawing by forcing a succession of dies over its end. In one embodiment, Figs. 1 and 3A, a tube 64 containing a mandrel 112 is clamped between a stationary clamp 66 and a clamp 68 which is movable by an hydraulic cylinder 78 via linkage 88-100. The mandrel is retained in position by dimples formed in the tube 64 by the clamping operation. A die 118 carried by a cylinder 26 is forced to the left by hydraulic cylinders 46, 48 over the end of the tube 64, after which the tube end is further reduced indiameter by first moving a cylinder 28 carrying a die 120 and then a cylinder 30 carrying a die 122. In another embodiment, Fig. 6B, a first die 160 carried by a crosshead 154 is forced by an hydraulic cylinder over the end of a clamped tube 1. As the first die 160 is being forced over the tube, further crossheads 156, 158 each carrying a pointing die are urged into engagement with the tube end by a member 188, constantly biased to the left by an air cylinder, in order to prevent bowing of the pointed end. When the die 164 in the last crosshead 158 is moved over the tube end, the extreme end of the tube is directly engaged by the member 188. In a further embodiment (Figs. 7 and 8, not shown), dies (244) are mounted by spring-loaded balls (242) in slots (238) of a rotary die holder (234) mounted on a crosshead (218). In operation, the uppermost die in the die holder (234) is forced over the tube end by moving the crosshead (218), after which the die is retracted, the die holder (234) rotated to bring the next die into position and the crosshead (218) again moved.

Abstract: 1308204 Screening apparatus SELECTION TRUST Ltd 20 Oct 1971 [20 July 1970] 35073/70 Headings B2H and B1D A screening apparatus, e.g. for separating industrial diamonds from alluvial gravel, comprises a rotatable frusto-conical drum screen 6, means for feeding the material to be screened into said drum at the smaller diameter end thereof, means for spraying a liquid from the drum axis towards the screen, means 31 for directing a fluid through the screen from the outside, and a set of flexible beaters arranged to strike the screen as it rotates over substantially all of its external surface. In operation, a mixture of the material to be screened and water is pumped from a supply 15 along the hollow shaft 2 into the rotating drum where it leaves the shaft through radial openings. Water from a supply 21 is pumped along the shaft in the opposite direction and also leaves through radial openings, the streams of water produced being directed by deflectors 22 which are arranged to direct said streams as shown or towards the smaller diameter end of the drum. The material travels along the inner surface of the screen 6 under the action of a component of the centrifugal force, the smaller particles passing through the screen and being removed through a connection 29 whilst the larger particles travel the whole length of the screen and are removed through a connection 25. The screen 6 extends between two rings 7 and 8 each ring consisting of two parts a and b between which the screen is clamped. The position of the ring past 8a is adjustable in an axial direction by means of bolts 12 and 13. The beaters striking the outside of the screen are preferably made of rubber and are mounted on a frusto-conical rotor driven about an axis parallel to and spaced from that of the drum. When the screen material is magnetic electromagnets may be located near the outer surface of the screen and fed with a suitable voltage waveform so as to vibrate the screen. Other modifications include the provision of flexible discs on the shaft 2, the periphery of each disc being arranged closely adjacent the inner surface of the screen, and the provision of a helical guide on the inner surface of the screen. The cone angle of the screen may be varied either continuously or stepwise.

Abstract: 1309910 Pulse laser distance-measuring BRITISH AIRCRAFT CORP Ltd 21 Jan 1972 [23 Oct 1970] 50526/70 Heading H4D In a pulse laser automatic range tracking rangefinder utilizing early and late gates an additional gate earlier than the early gate is utilized; there may be a further gate, later than the late gate. The invention obviates difficulties due to back-scatter, e.g. from smoke or fog, Figs. 1 to 8 (none shown). In the embodiment a range ramp generator 17 is triggered from a monostable 16 which also produces a delayed pulse to clamp the input of a range integrator 18. Whenever the range ramp voltage passes the voltage of the integrator, a comparator 19 generates a pulse to trigger a pulse generator 20 which produces the additional gate A, the early gate B and the late gate C. Unit 22 produced from received signals a signal corresponding to B-(A + C) and if this is non-zero the output of integrator 18 changes such as to alter the timing of the gates so that the echo energy is equal in gates B and C. A search generator 23 is incorporated. When the fourth gate is utilized, generator 20 generates an additional pulse (D, Fig. 3, not shown) initiated by the trailing edge of gate C, and unit 22 corresponds to (B+D)-(A+C).
