Abstract: 1,053,189. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 21, 1964 [Nov. 4. 1963], No. 42820/64. Heading H4P. Data is regenerated by sampling at a rate higher than the data rate and producing an output in accordance with the state of the largest number of samples having that state in a data pulse period. The Specification describes a binary pulse data regenerator in which the input signal is sampled seven times during an interval assumed to be equal to a data pulse period but which may be longer or shorter or otherwise non-coincident due to frequency or phase differences between the transmitter and receiver clocks. Reference is made to the use of multi-level data and to multiplex operation. In Fig. 1 (not shown), data received on line 10 sets a toggle LBT which is reset by clock pulses at seven times the assumed bit rate and provides the data samples. Each sample is carried to the appropriate one of two counters CTRI, CTRII, which respectively count the " 1 " and " 0 " samples. The countersare interrogated before receiving the next sample, and when a count of four is detected in either counter, memory LBT passes a 1 or 0, according to itscurrent state, to the output shift register 42. This bit is also set in to " Past Bit Store " PBT, for use during the next sequence, and sets a " Cycle Control Circuit " CCT which prevents further signals being applied to the register when the counters are again interrogated between any remaining samples of the sequence of seven. Once a counter has reached a count of 4, any further input pulses to it are passed to the other counter so that after the seventh sample one counter is at " 4 " and the other at " 3 ". whereupon decoder 78 causes the counters, memory LBT and circuit CCT to be reset for the next sequence. If the clocks are not synchronous some of the samples in the sequence may belong to another data pulse. Accordingly there is provided a " Previous Sample Memory " PST which is set to correspond to the binary condition of the sample. This is compared with the next sample and if they are the same a third counter CTRIII is advanced from its reset value of " 1 " to a value of " 2 ". If the next sample is different CTRIII is reset to 1. If however, four successive samples are the same a test is made firstly to see whether the bit has already been recognised by counters I and II, this being indicated by the state of CCT, and secondly to see whether the bit state of the four samples is the same as the state of the preceding received data bit stored in memory PBT. If the states are different and the bit has not already been recognized, counters CTRI and CTRII are reset to " 0 " and that corresponding to the present sample is then set to " 4 ". As a result. and as previously described, a pulse is fed to the register. After three more samples decoder 78 causes a new sequence to be started.

Abstract: 1,228,124. Contact printing apparatus. NATIONAL CASH REGISTER CO. March 12, 1969 [March 25, 1968], No. 12945/69. Heading G2A. In a contact printing apparatus, the master plate 46 is bowed into linear contact with the photographic film 16 by air pressure, and then the two are pressed into complete contact by a platen 48. As shown, the apparatus comprises a base plate 10 on which is mounted a die plate 13, above which is a support member 18 carrying a glass plate 26 thick enough to prevent flexing. Above this is mounted a glass master plate 46 which carries on it the master negative image. Plate 46 is thin enough to flex, and its edges rest in grooves 42, 44 in a guide member 20 secured by screws to support member 18. A lip portion 30 of member 20 has air-sealing O-rings 34, 32 above and below it, so that upper and lower glass plates enclose between them an air-tight chamber 47, into which air under pressure can be passed through a bore 54, 56. The film 16 is in the form of a continuous strip, passing step by step through the apparatus in a direction perpendicular to the plane of the paper. Above the film is a platen 48 of slightly resilient material (e.g. silicone rubber), mounted for vertical movement on a die plate 50. Light from a light source passes upwards through the two glass plates. Initially, after the film 16 has been advanced to the required position, the pressure inside chamber 47 is increased until the master plate 46 is bowed into the convex shape shown. Platen 48 is now lowered until the film sheet 16 just touches plate 46, in a line contact down its centre. Platen 48 is now pushed down further still, which tends to straighten the curved plate 46, and also to press film 16 against it Fig. 3 (not shown). Thus air pockets between film 16 and plate 46 are gradually squeezed out, and the two brought into good printing contact.

Abstract: 1,229,102. Endless conveyers for cigarettes. AMF Inc. 20 May, 1969 [29 May, 1968], No. 25719/69. Heading B8A. In an endless conveyer in which a plurality of containers 8 are carried past the bottoms of serially arranged delivery channels 11 of a hopper 10, and in which means 168 are mounted on each of the containers 8 for removing a rodlike article such as a cigarette S from the bottom of a stack supported on each of a plurality of shoes 165 respective to each channel 11 and causing the cigarette S to drop into the container 8 on its movement past the channel, the support shoes 165 are pivotally mounted at the rear edge of each respective channel 11 so as to extend forwardly in the direction of motion of the conveyer and oscillate vertically from an upper position (R.H. of Fig. 2) maintaining cigarettes S out of contact with the removing means 168, to a lower position (L.H. of Fig. 2) in which the lowermost cigarette S of the stack is positioned in the path of the removing means 168. Oscillation of the shoes 165 is actuated by cams 114 of a cam-shaft 119. Each shoe 165 comprises a laterally spaced pair of shoes, each of which has a suction duct 109 to retain a cigarette in position. A latch 121 can be operated by a solenoid 124 so as to retain any desired pair of shoes 165 in their raised position. The means 168 comprises a pair of laterally-spaced plates 168 on each container 8. Co-operating with the latter is a spring-loaded member 71 on the next immediately downstream container 8. If a cigarette fails to enter the intended channel 11, it engages an arm 125 (Fig. 1). This rotates a member 127 which carries two pulleys 130, 131 positioned below and above a longitudinallyextending wire 132. A predetermined increase in tension of the latter operates a microswitch 134. This energizes the catches 121, thereby causing all the shoes 165 to be retained in an upper position closing the outlets of the channels 11.

Abstract: 1,237,889. Typwriters. VARITYPER CORP. 7 Nov., 1968 [8 Nov., 1967], No. 52894/68. Heading B6F. A hammer impression arrangement in a typewriter includes a spring 22 for driving the hammer 18 for impression, and a second spring 42 which is normally applied to oppose the spring 22 and reduce the hammer impact for characters of small area, but which may be rendered inoperative for characters of large area. The mechanism is included in a proportional spacing typewriter wherein an escapement is selectively released for one, two, three or more increments according to the width of the character being printed. For characters corresponding to an escapement release of three or more increments a linkage 58 operates through a crank lever to rotate a rod 55 so that a finger 59 is depressed out of engagement with a leg 65 of a lever 44 to which the spring 42 is connected, permitting the lever 44 to pivot about a pin 47 so that the spring 42 is rendered inoperative, and the hammer 18 is driven by the spring 22 with maximum impact. For characters of less than three increments width, the rod 55 is not rotated so that the finger 59 prevents pivotal motion of the lever 44 and the spring 42 is rendered operative, reducing the impact of the hammer 18. A weak spring 67 is provided to reset the lever 44 after a maximum impact impression action. The force of the driving spring 22 is variable by means of a lever 24 which acts to move the lever 29 to which the spring 22 is connected. The opposing force of the spring 42 is also variable by a lever 53 which acts to pivot a lever 46 on which the lever 44 is pivotally mounted. The hammer may be reset by mechanism described in Specification 1,237,890.
