Title: Apparatus for monitoring changes of multiple inputs
IPC: G07C3/00
Filed: 1975-02-12
Abstract: 1487266 Selective signalling ASAHI KASEI KOGYO KK 12 Feb 1975 [15 Feb 1974] 5950/75 Heading G4H Apparatus for monitoring a change in a plurality of inputs scans the inputs, compares the scanned outputs with the scanned outputs of the same inputs in a previous scan from an update memory and, in the event of a change, reads from a main memory, and records, information relating to the input showing a change, the main memory including memory elements detachably mounted on a printed substrate. In a first embodiment, a clock-driven counter-chain controls the scanner and addresses the update memory which however stores the scanner output only in the event of change. When change occurs, the counter-chain output and scanner output are stored in a temporary memory (a shift memory or random access memory) which can store a sequence of such data so that scanning need not halt. The data is taken from this memory on a first-in-first-out basis and used to address a read-only main memory (which uses a removable labelled plug, incorporating one or more diodes, for each character) to obtain a message identifying the input which has changed and its status, this message being printed out together with the time from a clock. The temporary memory is read-out as fast as the printer can accept the information, and may be omitted if the printer is fast enough. In a modification, four groups of inputs are scanned concurrently to feed four comparators, the update memory being updated every scan. If any of the comparators shows a change from the previous scan, the comparator outputs, scanner outputs, scanner counter output and the time are entered into the temporary memory (which may be omitted) and passed from there on a first-in-first-out basis to a register from which the input which has changed (of the four) is identified by scanning, this identity and the other contents of the register (apart from the time) being decoded to address the main memory, the output of which is printed together with the time.

Title: Improvements in and relating to valves
Inventor: GOWER ARTHUR CYRIL
IPC: F16K5/06
Filed: 1953-03-04
Abstract: 748,888. Valve closure members. SAUNDERS VALVE CO., Ltd. March 3, 1954 [March 4, 1953], No. 6078/53. Class 135. A fluid controlling valve has a closure member in which is incorporated a non-return valve, the closure member, which is movable within the valve body for control purposes, being capable of occupying two positions in either of which the non-return valve directly communicates with the same fluid port in the valve body adjacent to the closure member but in one of which positions the action of the non-return valve is opposite to that which it has in the other position. In Fig. 1, a spherical plug cock similar to those described in Specifications 571,285 and 655,078 has a plug 11 engaging seating rings 13 sealed to the valve body 12 by flexible diaphragms 14 and the plug has a duct 15 which co-operates with aligned body ports 18, 19. The duct- 15 is widened as at 29 to accommodate a spring-closed lift valve in the form of a dish 21. The dish has a conical depression which receives the head of a push rod 24 carrying a spring 25 and guided in a boss 26 on a cross-bar 27. The dish 21 seats on the end of shouldered sleeve 28 held in the duct 15 by radial pins 34 engaging a groove 35, a circlip 36 engaging notches in the ends of the pins. The fluid flow may be cut off entirely or permitted in one direction or the other depending on the position of the plug. Fig. 3 shows a three-way cock having a plug 45 with an angular passage 44 containing a non-return valve 46. Fluid may pass from the connection 42 to the connection 41, the connection 43 being cut off or by turning the plug clockwise through 90 degrees, the connection 41 may be cut off and flow permitted from the connection 43 to the connection 42. A modified plug cock has three body connections and a plug with two passages at right angles. One of the passages permits an uninterrupted flow in either direction. A non- return valve allows flow in one direction through the other passage. Fig. 4 shows the invention applied to a gate valve. The valve body 52 has aligned connections 53, 54 between which moves a gate member 51 co-operating with flexible seating rings 58 and having a bore 55 flow through which in the direction of the connection 53 is prevented by a non-return flap valve 56. The gate 51 is raised by a crank pin 59 co-operating with an extension 61 of the gate. The gate may be taken out of the valve body and reversed so that flow in either direction may be arranged. The Provisional Specification also refers to Specifications 655,077 and 692,085.

Title: Lock
Filed: 1924-03-10
Abstract: 226,408. Fairbrother, H., (National Brass Co.). March 10, 1924. Sliding bolts; locks, square-key and like; cases for; keyhole escutcheons. - A tubular sheetmetal bolt is slid in a casing comprising two semi-cylindrical halves secured together by end caps having bayonet-joint connections with the casing, by means of a link pivoted at one end to the end of the bolt and at the other end to an arm on a hub turned by a square or like key. The tubular bolt 18 is reduced at its inner end 18<a> to pass under the operating hub 13, and has a pair of ears 19 at the end between which ears 20 on the link 21 fit and through which passes the pivot pin 22. The hub 13 turns in holes in the pressed-in parts 10 of the casing halves 3, 4 and has slots 14 for engagement with the ends 16 of the key 15. The other end of the link 21 is pivoted to an arm 17 of the hub. The front cap 8 and end cap 7 engage the casing, to hold the halves together, by pins 5 and bayonet slots 6. A front plate 9 is attached to the front cap 8 by bending over segments 32 of a flange to engage the inturned end of the cap, as shown in Fig. 6. The parts 31 of the flange form guides for the bolt. Fig. 3 shows the bolt withdrawn. To shoot the bolt, the key is inserted and turned to rotate the hub and swing the arm 17 over, causing the link 21 to pull the bolt to its position. The spring 24 round the pivot 22 causes the pivot to lie normally below the dead centre line so that pressure in the end of the shot bolt cannot cause it to enter the casing. A slot 30 is cut in the top of the casing so that the arm 17 can be made long enough to utilize the full size of the mortise of the door 1 and permit the longest possible throw of the bolt. An escutcheon plate 25 is mounted on one or both sides of the door and has a rotatable key-guide 27.

Title: Error detection in pcm systems
IPC: H04L25/48
Filed: 1973-02-08
Abstract: 1423776 Data transmission STANDARD TELEPHONES & CABLES Ltd 24 Jan 1974 [8 Feb 1973] 6211/73 Heading H4P In an arrangement for determining errors in the transmitted signals in a PCM system, in which for transmission purposes, digital words having one disparity polarity are transmitted when the accumulated disparity of the transmitted signals is of the opposite polarity, and vice versa, the polarity of the accumulated disparity of the transmitted signals is determined at the conclusion of each digital word and is temporarily stored at 3, the polarity of the disparity of a word in the transmitted signals is determined at the conclusion of each digital word and logic BB, CC determines when the polarity of the disparity for a digital word is the same as the polarity of the accumulated disparity stored at the conclusion of the previous digital word. In addition an error output is generated from DD, EE when the output of the logic BB, CC indicates that the two polarities are the same and the information in the temporary storage means 3 is connected when an error output is generated. As shown in Fig. 2 a 3 bit binary word representing word disparity is fed into a store 1 and a 3 bit binary word giving the accumulated disparity is fed from an arithmatic logic unit 2 to a further store 3. The stores 1 and 2 are controlled by a word rate clock and the outputs of the stores I and 2 control OR gate BB and NOR/OR gate CC. These gates BB and CC compare the polarities of the word and accumulated disparities to determine no error, positive or negative errors for controlling select function inputs #S0, #S1, #S2, #S3 of the arithmetic logic unit and NOR gates DD EE which provide an error pulse output for each disparity error. As the accumulated disparity can only have 6 possible values and must be either positive or negative and word disparity in a 4B 3T system such as disclosed in Specification 1,156,279 can have 7 possible values-3 positive, 3 negative and one of neither polarity this will introduce errors into the output of the unit 2. To overcome this a NOR gate AA is provided which functions to control gates BB CC and so prevent these errors. When the accumulated disparity is positive and is followed by a word disparity of +1 or the accumulated disparity is negative and is followed by a word disparity of - I an output F from gates FF and GG provides an inhibiting signal to the store 3 so as to help the accumulated disparity output AD from the store 3 unchanged. When an error is detected, the nature of the error is determined by gates AA, BB and CC and the function of arithmetic unit 2 is selected to apply the necessary correction to the erroneous accumulated disparity which is to be held in store 2 while the error is indicated at the output of gates DD and EE.

Title: Improvements in or relating to fabrics having crepe or similar figured effects and their manufacture
IPC: D06C23/04
Filed: 1931-03-02
Abstract: A process for the production of textile fabrics exhibiting cr<\>zepe or similar figured effects from medium or high twist yarns of non-thermoplastic filaments such as artificial silk of the reconstituted cellulose type, comprises subjecting the yarns, before or after weaving, to an embossing operation under heat so as to bring about a displacement of the yarns or the component filaments thereof. An enhanced cr<\>zepe effect is thus obtained, or alternately, yarns of lower twist than that required to produce a cr<\>zepe effect without further treatment may be employed.  For the woven fabric the embossing may be obtained by a roller having a raised surface corresponding to the surface of a cr<\>zepe fabric, or surfaces consisting of a series of small intersecting geometrical figures such as circles, squares, triangles, &c., may be used, the usual finishing process in the latter case obliterating the figures and leaving the cr<\>zepe effect on the surface of the fabric.  The embossing surfaces, e.g. rollers, are adjustably spaced apart so as not to injure the fabric and may have intermeshing patterns thereon which, however, do not contact with each other.  If the yarns, either warp or weft, are treated before weaving, the embossing devices may be similar to those used for the woven fabric or may consist of a series of regularly or irregularly disposed axial or diagonal ridges which flatten or corrugate the yarns.  Cr<\>zepe yarns prepared as described in Specifications 357,576 and 357,577, [both in Group IX], may be employed and the embossing treatment may be applied before, during, or after twisting.  Further, in order to improve the effect, yarns may be treated with swellable sizes such as are described in Specifications 348,589, 352,451, and 357,169, or swelling of the yarns may be resorted to as described in Specifications 352,000, 356,233, and 357,084.  Further, fabrics having alternate disposition of right- and left-hand medium or high twist yarns may be employed, or either the weft or warp may have low twist yarns.  The yarns may be moistened before being treated.

In a process for the production of a semiconductor component, one face of a monocrystalline body of semi-conductor material of one conductivity type is stepped so as to provide the face with a plateau-like portion, metal containing doping material is applied to the top of the plateau-like portion in the form of a metal foil of such extent that it does not overlap the perimeter of the top and that the shortest distance of the edge of the foil from the perimeter is nowhere substantially greater than the thickness of the foil, and the metal containing doping material is then alloyed-in to the top of the plateau-like portion so that a zone of opposite conductivity type is produced in the body, the zone extending completely across and being included completely within the plateaulike portion so that the PN-junction between the zone and the rest of the body is substantially planar. The plateau-like portion may stand proud of the rest of the face of the semi-conductor body, or it may be formed by etching or mechanically working a groove in the face. In the production of a transistor a number of concentric annular plateau-like portions may be formed. The semi-conductor material may be germanium or silicon, and the foil may be made of aluminium or gold and antimony.
