Abstract: 700,875. Splicing rubber tubes. PIRELLI SOC. PER AZIONI. April 23, 1951 [Aug. 4, 1950], No. 9420/51. Class 70 A machine for joining the ends of unvulcanized rubber tubes comprises a pair of clamps in which the tube ends are placed in such positions that the extremity of the end in each case protrudes beyond the front of the clamp towards the opposite clamp, the clamps being automatically closable upon the tube ends so placed in position, as a first stage in the cycle of operations of the machine, and automatically operable to enable the joined ends to be removed, as a later stage, and an automatic knife to cut off the protruding extremities of the tube ends in position in the closed clamps, at least one of the clamps being reciprocatable towards and away from the other clamp once in each cycle of operations, and three driven cams transmitting their motions through associated lever systems to open and close the clamps, operate the knife and reciprocate the movable clamp in timed sequence so that freshly cut edges of the tube ends are brought into contact with one another, and are then, by continued movement of the clamp, compressed together. In the apparatus of the drawings (Figs. 8, 9, 10) the clamp halves comprise body portions carrying clamping faces 23 for the tube ends 41 and 42 and fillets 18 and 27 at the front ends of the clamps, which fillets have freedom for sliding movement relative to the body portions inwardly and outwardly against springs in the clamp halves, the fillets of each clamp half being disposed to underlie and overlie the portion of the tube end which projects beyond the body portion of the clamp half and to abut the corresponding fillet of the opposite clamp during the end of the relative approach of the clamps and the beginning of their recession. These fillets support the projecting portions of the tube ends during the cutting by the knives 43 and 44 and during the approach of the clamps to present the freshly cut edges of the tube ends, at the end of the approach of the clamps, into register with one another. The fillets recede into the body portion of each clamp under thrust from the opposite clamp to permit pressing together of the freshly cut edges of the tube ends during the end of the approach of the clamps. The knives 43 and 44 skim the front faces of the fillets in cutting through the tube ends; to facilitate cutting and complete severance of the tube ends and also to cause the severed ends to fall clear, the protruding extremitv of each tube end 41, 42 bears. during the cutting, against a surface 45, 46 disposed near the path of traverse of the knife blade.

Abstract: 1308805 Making electric coils; winding and reeling G CAMARDELLA 26 Feb 1970 [3 March 1969] 9453/70 Headings B3A and B3E A plurality of working operations, which include a basic working operation requiring a relatively long time and a complementary working operation requiring a relatively short time, are performed on successive workpieces, such as coil supports 2, by moving them stepwise through a series of working stations 0-VII wherein the basic working operation is performed simultaneously on two or more workpieces at two or more stations respectively, and thereafter the workpieces are advanced to a station or stations where the complementary working operation is performed. A machine for winding electric coils includes an intermittently rotatable turret 1 for feeding coil supports and wound coils 2 to operational stations around the turret. At 0 a device 3 automatically feeds the coil supports on to holding spindles 4 on the turret. No operation is effected at position I: in positions II and III winding heads 5 and 6 wind two coils simultaneously to produce identical or different windings: at position IV the windings are waxed by apparatus 7; at position V shears 9 are provided for cutting the wire connecting two coils at either of places 10 or 11: at position VI terminal bending and/or tinning devices may be located: at position VII a mechanical 12 or pneumatic (not shown) unloaing device for the wound coils is provided. In operation after the winding steps at positions II and III, the turret is rotated one step to bring the first wound coil to waxing station IV for a brief stop where it is waxed. An operation is carried out on the second wound coil at position III. The empty spindle at 0 is loaded with a coil support. The next step is a prolonged one as empty coil supports have arrived at positions II and III for the winding operation. The indexing turret therefore exercises a series of brief and prolonged stops. In another embodiment a further winding head is installed at position I in which case the turret is rotated to make two short stops and one long stop every three steps; alternatively the machine may have six heads for winding six coils simultaneously. In a further embodiment the winding heads in positions II and III are each provided with four parallel wire guides operating in correspondence with four spindles 4 on the turret or a plurality of wire guides operating on shorter coils mounted on the same spindle 4.

Filed: 1920-04-06
Abstract: 160,366. Fairbrother, H., (Lynch Glass Machinery Co.). April 6, 1920, Blowing. - Relates to machines for blowing glass hollow-ware of the type in which a number of turnover parison moulds and an equal number of finishing- moulds are carried on two separate rotating tables on the same level, the transfers of the blank from the parison mould to the conesponding blowing - mould taking place where the mould paths meet. The machine is pneumatically operated and is arranged so that, in charging the parison mould, the gatherer strikes a valve lever with the gathering-iron, after which all operations are automatic, including the delivery of the finished article. The machine is shown in plan in Figs. 1 and 2a taken together, and in vertical section on the line 2-2<a>, Figs. 1 and 1<a>, in Figs. 2 and 2a taken together. Figs. 1 and 2 show the parison mould table and Figs. 1<a> and 2<a> show the blow mould table. The parison moulds 45 are charged by hand at station I, Fig. 1. The gatherer depresses the lever 138 which admits air to the cylinder 117, Fig. 3, operating shears 111 which cut off the charge. An air-cooled neck rod 133 rises and a cover 105 descends, air being admitted through the latter to compress the charge. At station II the blank is partly blown. In passing from station II to station III, the parison mould is inverted and at the latter station the blank mould opens and releases the blank, and the finishing-mould closes upon it. At station III<1>, the blank is blown and at V' it is lifted from the open blow mould on to a conveyer 245 by pneumatically-operated grippers 235, 236, Fig. 6, mounted on a slide 220.

Abstract: 1313125 Taximeters KIENZLE APPARATE GmbH 19 April 1971 [29 April 1970] 9872/71 Heading G4T [Also in Division H1] A keyboard control unit for a taximeter (Fig. 1, not shown) comprises a switching key 34 to 39 associated with each function of the taximeter, locking means 30 being provided to prevent the actuation of some of the keys 34 to 37, the locking means being releasable to permit actuation of these keys by a " For-Hire " key 38. This arrangement ensures that the taximeter is returned to the " For-Hire " position before the start of each new journey. In the embodiment described the keys 34 to 37 are associated with different tariffs and key 39 is a "Cash" " key. Actuation of a tariff key 34 to 37 is normally blocked by a pin 19 on the key shaft 11 engaging an abutment 48 on the spring-urged locking slide 30. Depression of " For-Hire " key 38 displaces slide 30 to the right on engagement of pin 19 with sloping abutment surface 33 of slide 30 and allows the pin 19 of another key to enter a recess 31 in the slide. The ends 25 of the key shafts 11 act on respective contact banks 26. Keys 34 to 38 are held in their depressed positions by means of a spring urged locking comb 40 the teeth of which co-operate with respective recesses 20 and noses 21 of the key shafts 11. The actuation of one of these keys releases any other depressed key, the actuated key then being held depressed. The " Cash " key 39 serves as a common release key for any depressed key but is not itself held in a depressed position, and also acts to disconnect the timedrive to allow for luggage unloading &c. To prevent the simultaneous depression of more than one key displaceable blocking discs 28 are provided arranged so as to allow the entry of only one projection between any two adjacent discs. A depressed key is illuminated by a lamp 15 underneath the key-buttons 10 which are pivotably mounted on the key shafts to permit easy replacement of the bulbs. The taximeter itself (Fig. 1, not shown) has a blind (3) with windows (4), (5) and (6) for the fare, extras and totals indicators respectively.

Patent HK-134196-A (HK)
Title: Video coder
Inventor: MORRISON DAVID GEOFFREY
IPC: H04N21/242
Filed: 1996-07-25
Abstract: A coder assembles bursts of blocks of image data (eg transform coded coefficients) and associated overhead data into a sequence of data which are then transmitted. Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory stores (21)(22). The blocks of transform coded coefficients have a 'last coefficient' flag accompanying the last coefficient, and the overhead information contains a unique word SWITCH, after the header information but before the 'end-of-block' flag. The 'last coefficient' flag and the SWITCH word are recognised by a toggle controller (29) which controls the reading of the stores so that the coefficient data and overhead data are selectively passed to a buffer (30) in a desired sequence. The buffer (30) is followed by a variable length coder (31) which supplies the output of the coder at a constant bit rate. Provision (34-38) is made to calculate the quantity of output data represented at any time by the contents of the buffer and the result is used to control the rate of generation of image data.
