Title: Improvements in or relating to tool-setting indicators for machine tools
IPC: B23Q17/22
Filed: 1941-08-16
Abstract: 549,404. Position Indicators. FERRANTI, Ltd., BEESLEY, J., and HOLMES, S. W. Aug. 16, 1941, No. 10445. [Class 40 (i)] [Also in Group XXII] A tool setting indicator for a machine tool such as a capstan lathe, particularly for repeatedly setting a tool p, Fig. 2, to precisely the same position for making a succession of workpieces of the same dimension, comprises a push rod i secured to an armature e associated with inductance coils a, a<SP>1</SP> carried on iron cores c, c<SP>1</SP>, the coils forming arms of an inductance bridge fed from an A.C. supply and having connected in circuit a microammeter (not shown) which is responsive to the axial position of the push rod. The armature is mounted on a strip spring f and the bridge circuit is normally adjusted to give zero reading when the armature is in a central position. The indicator K, Fig. 2, may be secured to a lathe saddle and the rod i is engaged by one of a series of stops o associated with the tools p of the tool head n mounted on the cross slide m. The stops are adjusted so that movement of a tool to the desired position gives a small displacement to the push-rod and consequently an indication on the microammeter, the same indication being obtained for each repeated operation. The push-rod is supported only by the armature and by metallic bellows j secured to the frame so that friction is eliminated. In a modification the E-frames are reversed and two spring- mounted armatures are secured to the push rod which has turn-buckle adjustment. In another modification, Fig. 4, the push-rod is carried by two diaphragms r, r<SP>1</SP> fixed to the frame and passes through holes in the centre limbs of the E-frames; or the diaphragm may be replaced by two sets of bellows similar to those shown at j, Fig. 1.

Abstract: 734,633. Control of two A.C. motors. BROOKHIRST SWITCHGEAR, Ltd., and SHREEVE, A. G. April 20, 1954 [April 18, 1953], No. 10662/53. Class 38 (3). Two polyphase induction motors 11, 12, driving opposite ends of an ore bridge are adapted to be connected in parallel on the stator and rotor sides for operation in synchronism, means being provided for initially interconnecting those secondary phase windings of the two motors which are most closely in phase which regard to terminal voltage. Relays 20, 21, 22, are connected in the rotor circuit of the motors, and, when the current-supply to the stators 13, 15, is first switched on, the highest voltage is applied to that relay which interconnects the two rotor windings which are most out-of-phase. Similarly, the next highest voltage is applied to the relay connected to the rotor windings which are next most out-ofphase. The selective operation of these relays causes the closure of a contactor 17, 18, or 19 which thereby inter-connects the windings of the two rotors which are most closely in phase. Starting, slow-down, and inching resistances 23 are provided in addition to slip resistance 24. The relays 20, 21, 22, may have capacitors in parallel with their coils fed through a permanent resistance and rectifier.

Abstract: 309,999. Wagner, K. W. April 19, 1928, [Convention date]. Drawings to Specification. Combined transmitting and receiving systems; duplex signalling.-In a two-way carrier wave system, transmitting by wire or radio, the same carrier wave is used in both directions. At the control station, the wave is generated and modulated, and the carrier and both side-bands. are transmitted, although the carrier may be partially suppressed. At the other station, the carrier is separated from the side-bands and after amplification is modulated for sending signals back to the control station. For the reverse transmission the carrier is suppressed and only one side-band is communicated, de-modulation being effected at the control station by combining the received side-band with the local carrier.

Title: Improvements in automatically operating heat control means in sterilisers
IPC: A61L2/24
Filed: 1954-04-14
Abstract: 809,062. Sterilizers. PETERS, C. W. July 11, 1955 [April 14, 1954], No. 10929/54. Class 81 (1). [Also in Groups XIII and XXIX] A thermostatically-controlled device to control a valve controlling the supply of heating medium to a sterilizer, comprises a housing A having a branch B through which vapour from the sterilizer passes and temperatureresponsive bellows F, G arranged in tandem and connected to a spindle H to operate the spindle K of a steam or gas supply valve L. On initial boiling of the sterilizer the vapour-filled bellows F anchored at its upper end and enclosed in a perforated shroud expands to move the bellows G, and through it the spindles H, K to move the valve towards closure. Should the boiling be excessive the vapour creeps down the housing to envelop the less sensitive liquid-filled bellows G which also expands to close the valve still further. To prevent excessive boiling when the lid is raised a spring Q held compressed through linkage M by the lid is released to close the valve. The spring Q abuts a collar R slidable on the spindle H so as not to interfere with the normal operation of the valve. The bellows F, G may be fitted separately, with or without the lid-operated spring. The bellows F is used when quick boiling from cold is essential but fine adjustment afterwards is unnecessary. The less sensitive bellows G is used when quick boiling from cold is unnecessary but fine adjustment afterwards is desirable.

Title: Data network terminal unit
IPC: H04L1/00
Filed: 1971-04-23
Abstract: 1362653 Speed changing in digital data transmission systems STANDARD TELEPHONES & CABLES Ltd 8 Feb 1972 [23 April 1971] 11016/71 Heading H4P To match the slower operating bit rate of a subscriber data terminal to the higher line transmission speed, a unit adds, or extracts according to the direction of transmission, M control bits for every N data bits transmitted, or received. In the arrangement described for every group of eight data bits a control bit is added after the fourth and eighth data bits, for synchronization or error correction purposes. Fig. 1 shows a circuit for receiving bits D from the line arriving at a bit rate A which are sampled by clocked bi-stable FF2 at n/n+m, i.e. 4/5, the rate A, i.e. with a sampling signal having a bit period 1<SP>1</SP>/ 5 th of the bit period of the arriving bits D, whereby no sampling takes place during the periods of the two control bits per group of eight, which control bits are sampled by bistable FF1 clocked by signal G. A synchronization clock F is compared with that one of the control bits acting as a synchronization bit to maintain the system in synchronism by adjusting the counter which generates clock signals F, G and C from the fundamental bit rate A and twice this frequency B. In the transmitting circuit Fig. 2, data from the terminal is sampled by bi-stable FF3 clocked by signal C at 4/5ths the transmission line bit rate A, to produce a data stream J, which is blocked by gate GG1 for the period of the synchronization control bit, i.e. overlapping the junction of bits 4 and 5 of signal J, which synchronization bit is then introduced by gate GG2 clocked by signal K, and for the other control bit period overlying data bit 8 of one group and data bit 1 of the next group, which second control bit is introduced by bi-stable FF4 and gate GG3 clocked by signal L. The data bits J and two control bits are combined at OR gate GG4 and then sampled for transmission to the output line by bi-stable FF5 clocked by the line bit rate signal A.
Patent GB-850998-A (GB)
Title: A method of and machine for manufacturing wall, roof and like covering elements
IPC: E04C2/26
Filed: 1959-04-01
Abstract: <PICT:0850998/III/1> Covering elements are made by placing wood boards end to end, joining the ends to form a continuous run, coating at least one side of the run of boards with a sheet of metal or synthetic plastic material, or with asphalt, and cutting the coated run into required lengths at places other than at the joints between the boards, so that these joints are covered with the coating.  As shown, wood boards are advanced longitudinally one after the other to and through a planer 2 where their longitudinal edges are grooved. Feed rollers 3 advance them to the stop 4.  The board is then moved transversely as indicated by arrows 5, during which movement the end of the board is faced by the cutter 6 and coated with adhesive or hardener for adhesive by the brush or roller 7. The board is then moved longitudinally as shown by arrow 9 to the stop 10, when it is again moved transversely and the other end faced by the cutter 11 and coated with adhesive or hardener by the member 12.  Adhesive may be applied to one end of the boards, and hardener to the other.  The board is then longitudinally advanced to feed rollers 16 and 17, of which the latter rotates more slowly than the former, so that the ends of consecutive boards are pressed together.  The resulting run of boards is passed through an apparatus 18 which coats at least one side, and preferably part of the longitudinal edges with a sheet of metal or synthetic plastic material or with asphalt.  The run is then advanced to an electric contact device 19 where it is cut to length by a crosscut saw 20, which during the cutting operation is moved synchronously with the run of boards, the cutting being other than at the joins of the original boards.  The cut boards are moved transversely on to a conveyor 21 which feeds them to a bundling apparatus 22. The stops 4 and 10 may be electric contact devices controlling the feed rollers.

Title: A method of and apparatus for identifying objects
IPC: G07G1/00
Filed: 1970-03-09
Abstract: 1300965 Automatic vending machines ZELLWEGER Ltd 9 March 1970 [21 April 1969] 11121/70 Heading A4T In an automatic vending system an article is provided with information, e. g. a price or weight label, which is automatically read and, if found to be within predetermined limits, is automatically released to the customer. This prevents two articles being placed on top of each other and the customer being charged for only one. In the Fig. an article 1 is marked and passed on a conveyer into the reading zone 2 of a reader 3, which may be a photo-electric device. The reading from the article is passed by way of a line 3a to a computor 4 which identifies the article from its marking and passes the result to a store 5. The article then passes by means of a conveyer 6 to a measuring device 7 which weighs the article and passes this information to a comparator 8 which also receives information from the reader 3 by way of lines 3c, 3d. If the comparison of these results are within predetermined limits the article is discharged by a conveyer 9 to a container 11 and a signal is passed by way of a line 8c to the computor which passes the signal to the store 5. This system is repeated for as many items as the customer passes through the reader and the signals from the store 5 are passed to a totalizer 13 which passes the total cost to a cash register 15 and, when payment has been made, or credited to an account, the customer presses a button 12 on the reader 3 which releases the articles from the container 11. If the comparator 8 finds the readings incompatible a conveyer 10 passes the articles back to the reader 3. In the event of a faulty or unsuccessful reading a conveyer 6a may return the article to the start of the system. The sequence of reading and weighing may be reversed or both may be performed simultaneously.
