Title: Projectile Driving Bands.
Inventor: CROSSLEY HENRY MORTON
IPC: F42B14/02
Filed: 1966-10-25
Abstract: 1,164,299. Moulding ring members; thermosetting laminate. HENRY CROSSLEY (PACKINGS) Ltd. 12 Oct., 1967 [25 Oct., 1966], No. 47844/66. Headings B5A and B5N. [Also in Division F3] A projectile driving band which fragments and is discarded from a projectile as the projectile leaves the muzzle of a gun is made by impregnating a length of fibrous material with a thermosetting resin, dipping the impregnated material in an inert filler, cutting the impregnated and dipped material into strips, superposing the strips in a mould and bonding them together by pressure, e.g., of 1 ton per square inch without complete curing of the thermosetting resin, forming the laminated structure into narrow wedges by punching or cutting, loading the wedges in a circular die so that the planes of the laminates are radially disposed, and applying heat and pressure, the temperature preferably being 320 F. and the pressure 3 tons per square inch, so as to bond the wedges together to form a rigid moulding. The fibrous material may be woven asbestos cloth, jute, woven cotton cloth, hessian or glass cloth and may incorporate small amounts of metallic strands, e.g., of copper. The resin may be a phenol resin such as cresol formaldehyde or phenol formaldehyde. The inert filler may be P.T.F.E. which is coated on to the strips before the partial bonding or an ebonite solution consisting of "Hycar" (Registered Trade Mark), butyraldehyde/aniline complex, zinc oxide, light calcined magnesia, red iron oxide, dibutyl phthalate and carbon black made up as a solution in toluol and ethylene dichloride. The solution may incorporate P.T.F.E. powder. To increase the fragmentation effect of the band the wedges may be warmed and dipped into P.T.F.E. powder prior to moulding and bonding.

Abstract: 1,270,357. Lateral adjustment of endless conveyers. GOODYEAR TIRE & RUBBER CO. 8 Oct., 1970 [3 Nov., 1969], No.47891/70. Heading B8A. [Also in Division B7] Conveyers C and D, Fig. 1, form part of means for conveying tyre building stock S from a supply roll R thereof to a tyre building drum 22 in a tyre building apparatus (see Division B7) and are arranged one above the other extending between their respective stock receiving ends 200, 202 which ends are elevated substantially above the respective supply rolls R, R<SP>1</SP> while the respective delivery ends 204, 206 of the conveyers are disposed at a lesser elevation above the drum 22. The conveyers C, D have first drive means in the form of a gear motor 250 operative to advance a leading edge portion of the stock S towards the drum 22 and in a reverse direction and also a second drive means which maintains the surface speed of the drum 22 and endless conveyer belts 220, 226 equal. The apparatus 10 has detector units 374, 376, Fig. 4, in the form of photocell units on guide assemblies 349, 351 to locate the respective transverse leading edges E, E<SP>1</SP> of the stock S at predetermined positions represented by transverse lines 370, 372 respectively on conveyers C and D. Timers (574) and (582) which form part of an electrical control means of the apparatus 10 are adjusted to provide a time interval such that the leading edge E of the stock on the belt 226 is moved from its predetermined transverse line 372, at which the stock at rest terminates, to a predetermined position relative to the drum 22, where the leading edge E of the stock intersects the mid-circumferential plane of the drum 22 in its upper quadrant Q. Further, the apparatus 10 has means to effect lateral displacement of conveyers C and D from a generally centred position relative to a plane 36, displacement being provided for by supporting side members 210, 212 on a cross slide bar 400 fixed at its respective ends to columns 18 and 20 and extending parallel with axis 24 and a second crossslide bar 402 fixed at its respective ends upon beams 14, 16 and extending parallel with the bar 400. The bars 400, 402 are each translatably engaged by a pair of linear bearings 404, 406 of the circulating bell type, the bearings 404, 406 being secured to the side members 210, 212. Lateral movement of conveyers C, D is effected by a gear motor 410. Operation of the apparatus 10 is effected by a plurality of circuits including particularly a stepping programme controller by which successive circuit combinations are established in a preset sequence.

Abstract: 1351380 Vending machines GLORY KOGYO KK 20 Oct 1971 [23 Oct 1970] 48684/71 Heading G4V In a vending machine signals from article selection switches P 1 -P 6 , signals produced on lines J 1 -J 6  of a price setting circuit J according to the value of coins dropped into the machines, and signals succeedingly and repetitively produced on lines L 1 -L 6  of a rotation converting circuit Mx fed by pulses from a pulse oscillator O, are fed to a three-condition collating circuit NA 2  having gates A 1 -A 6  which in the event of suitable inputs feed a signal to a clutch section K to control respective ejection devices for delivery of the selected article. The circuit NA 2  produces a further signal when the input conditions of any one of the gates A 1 -A 6  are satisfied to block a control gate NA 1  between the pulse oscillator O and the converting circuit Mx so that the output of this circuit is held on the particular line L 1 -L 6  connected to that gate. The pulse oscillator O is preferably arranged to be switched on when the first coin of each transaction is dropped into the machine. In a further embodiment (Fig. 2, not shown) the gates A 1 -A 6  are connected to a common flip-flop (M), the output of which is fed to gates (A 11 )-(A 16 ) of a two-condition collating circuit (NA 3 ), these gates receiving at their other input the signals on lines L 1 -L 6  and having the outputs connected to the clutch section K. In order to ensure that no more pulses are fed to the converting circuit Mx after the input conditions of one of the gates A 1 -A 6  are satisfied, which might occur if say a selection switch were closed near the end of the duration of a signal on one of the lines L 1 -L 6 , a delay circuit (D) and further two condition collating circuit (NA 4 ) may be added (Figs. 4 to 6, not shown). This result may also be achieved by arranging the pulse oscillator to be operated only after closure of a selection switch.
