Title: Data transmission apparatus
IPC: H04L7/00
Filed: 1969-11-20
Abstract: 1275446 Digital tsansmission systems; synchronizing INTERNATIONAL BUSINESS MACHINES CORP 20 Nov 1969 [28 Feb 1969] 56770/79 Heading H4P [Also in Division G4] A synchronization detector system for an input train employing pseudo-random sequence data coding of specific length comprises a generator for producing a reference pseudo random sequence in response to the input train, a comparator comparing the reference sequence with the input train, bit by bit, and giving an indicator signal for each equal comparison, and a detector generating a synchronizing signal in response to a predetermined number of successive equal comparisons less than the number of bits in the train, and a second detector identifying the position in the train. The reference sequence is generated in a shift register 1 coupled with an OR gate 2 in manner known per se, the register producing a series of bits which are compared serially and sequentially with an incoming train of 31 bits in an example described, each identity being registered in a counter having a detector of a specified number less than 31, the specified number being dependent on the probability of error, e.g. 22 successive agreements indicate a probability of error of 1 Î 10<SP>-8</SP>%. When synchronism is sought the input train is passed through gates 6, 7 to shift register 1 which is coupled to exclusive OR circuit 2 generating a sequence of 31 bits are compared in circuit 16 with the incoming train bit by bit. Agreement at any point(s) sends a signal over line 17 through gate 12 to step a counter 19 one count. If there is no agreement a signal on line 18 through gate 13 sets the counter 19 to zero. When a determined number of counts is reached a detector 15 applies a synchronizing pulse to a flip-flop 9 which switches through gates 6-8 the input to register 1 to OR gate 2, the register continuing to generate the reference sequence until a detector 3 recognizes a selected one of the 31 patterns of 5 bits thus establishing a point of reference with respect to the input train. The selected one may be designated as a last bit. The output from gate 2 continues to be compared with the input train in the comparator 16 the output from which is switched through gates 10, 11 to a detector 14 which may be in the form of a counter counting up for each equality and down for each inequality and at a determined number will provide an output to switch the circuit back to its synchronizing state.

Abstract: 1,243,636. Olefin copolymer elastomer compositions. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd., and D. A. SMITH. 10 Dec., 1968 [29 Dec., 1967], No. 59194/67. Heading C3P. [Also in Division F3] The lining of a case-bonded solid propellant rocket motor comprises an elastomeric-containing compound including 100 parts of elastomer, 40-100 parts of filler material, and 20-80 parts by weight of at least one chemical compound compatible with the other contents of the elastomer-containing compound and having a temperature of endothermic decomposition above the temperature of the initial decomposition of the elastomer. In a typical embodiment, the 100 parts of elastomer consists of 75-100 parts of a terpolymer of ethylene and propylene and a diene containing unsaturated linkages of unequal reactivity (e.g. Shell ECP 900) and 25-0 parts of a chlorosulphonated polyethylene (e.g. Hypalon 40). The filler material is SiO 2  powder. Either Ca(OH) 2  or Mg(OH) 2  may be used as the chemical compound, both having an endothermic heat of decomposition in excess of that of the elastomer. Heat is absorbed by the chemical compound, thus reducing the temperature of the liner and thereby the rate of loss of the elastomer content itself. The abovedescribed terpolymer results in a low density liner but if density is relatively unimportant, other elastomers such as nitrile rubbers, chlorosulphonated polyethylene rubbers, styrene-butadiene rubbers, butyl rubbers, polyisopropene rubbers, ethylene-propylene copolymer rubbers, and silicone rubbers may be used.

Abstract: 1367365 Charging coke ovens WOODALLDUCKHAM Ltd 10 Nov 1972 [29 Dec 1971] 60494/71 Heading F4B A horizontal coke oven battery with a single collecting main at one side connected to each oven by an ascension pipe and with lidded breeches pipe connections at the other side, comprises a breeches pipe carriage running on a track extending between parking areas beyond each end of the battery, a breeches pipe on said carriage with means for handling it and means for handling the lids of the connections, coupling means on said breeches pipe carriage and on a charging car for coupling said carriage and said car together at either of two relative positions in the direction of motion thereof, said positions being spaced apart by the distance between adjacent connections, actuating means near each parking area for coupling or uncoupling said carriage and said car, and control means on said car for actuating said breeches pipe handling means and said lid handling means when the carriage is coupled to the car. As shown, the charging car 6 carries coupling jaws 9 by which it is attached to or detached from the breeches pipe carriage 11 by means of stanchions 14 or 15. It also carries conductor rails 10 engaging collector shoes 13 on said carriage. The latter travels between stops 5 on rails 4 over the lidded connections 2 and the charging car 6 runs on rails 7 from a bunker 8 one of said rails 7 having ramps 37 and 38 at opposite ends of the battery and on opposite sides of the rail. The jaws 9 have individual members 9a, 9b pivotally mounted at 16 on sliders 17a and 17b and urged into an extended position by springs (21a, 21b, Fig. 3), the sliders being similarly loaded by springs 23a and 23b. Each jaw member 9a, 9b has a lock bar 24a, 24b carrying rollers 25, 26 and urged forward by springs 28a, 28b, whereby the rollers 25 engage the jaw tail plates preventing rocking about the pivots 16. The locks may be retracted by cables 29a, 29b. The lock bars 24a, 24b also have a nib (30a, 30b, Figs. 3 and 4) released by linkages from a pivoted lever (36a, 36b) operated by a ramp 37 or 38 as the car moves away from the battery. The arrangement is such that the trailing jaw is thus unlocked releasing the carriage. As the charging car 6 approaches the battery from the bunker 8, the jaws 9 will pick up the carriage 11 by stanchion 15 and any oven subsequently being charged will be connected by the breeches pipe 12 to the next oven in the direction of movement. At the far end of the battery, before the last oven can be charged, the car 6 runs past said far end, is disconnected from the carriage by ramp 38, and then returns picking up the carriage by stanchion 15 so that when positioned over the end oven its connection 2b is connected by the breeches pipe 12 to the adjacent connection 2. Controls on the charging car 6 operate the breeches pipe and lid handling mechanisms on the carriage 11 through conductor rails 10 and collector shoes 13. Suitable interlocks provide for correct sequential operation with the other charging car controls.

Title: Monitoring angular position in cycle
IPC: H02P5/56
Filed: 1978-07-14
Abstract: A displacement encoder (3), mounted on a shaft (1) in a loom transmits a first signal (S1) once during each revolution of the shaft in a preselected angular position thereof, and transmits second signals (S2) in response to incremental angular displacements of the shaft. A counter (11) is reset to zero in response to reception of each first signal, and then counts the second signals until the loom shuttle (117) causes the generation of a third signal (S5) when it reaches a predetermined position. A logic circuit (15) begins transmitting the second signals to the counter on receiving a first signal, and terminates transmission of second signals to the counter on receiving the next following third signal. The number of second signals stored in the counter denotes the angular displacement of the shaft from its preselected angular position. <IMAGE>

Title: Displacement sensing device and liquid gas tank gas level indicating system
IPC: G01F23/38
Filed: 1978-08-22
Abstract: A gas tank gas level indicator utilises a float 2 which rotates a shaft 7 via gears. The shaft 7 drives a shaft 10 outside the tank through a ss magnetic coupling 8 and 11. An optical pick off utilises a light emitting diode 13 and a cadmium selenide photoresistor 14 with mutually compensating temperature characteristics. A variably opaque rotary disc 12 (also Fig 2, not shown) on the shaft has five discrete sectors of which one is white, one is black and the remaining three are of graded shades of uniform grey in effect, the "grey" being produced by finely drawn alternate lines and spaces whose relative widths vary from one grey sector to the next. The light detector has a relatively wide field of view and, over much of the range of rotation of the disc, the light detector is receiving light through parts of one or other pair of adjacent sectors, the relative proportions of the parts of the sectors through which the light passes being progressively variable as the disc rotates, so as to give a sloped characteristic. A signal processing circuit is disclosed (Fig 3 not shown). <IMAGE>
