Title: Gate valve for high pressure abrasive carrying fluid
IPC: F16K3/02
Filed: 1954-03-03
Abstract: 749,932. Manually-actuated valves. VALVES, Inc., E. March 3, 1954 [Aug. 18, 1953], No. 6214/54. Class 135. A composite removable seat unit for a gate valve 28 comprises spaced parallel resilient rings 120, 122 interconnected along a part of their circumference at 124 by a resilient bridge and rigid reinforcing rings 130, 134 lining and bonded to the resilient rings. The rigid rings have retaining lips 136 engaging under body shoulders. Inlet pressure at 32 moves the gate, loosely attached to its spindle 24, to sealingly compress the ring 122 which has ridges on its opposite faces so that inlet pressure passes the ring 120 to enter the chamber 41 and press on the ring 122. A crescent-shaped raised portion 125 not bonded to the rings seals with the base of the gate while a projection 139 reinforced by metal 142 enters a body recess 140 to prevent the seat from turning. Four modifications are shown in which different methods are used to prevent the seat turning. The handle bar 76 secured to a loose ring 72 passes with lost motion through an opening 82 so that an initial impact is applied for turning the boss 90 operating the stem through differential screws 64, 68.

Title: Telephone system
IPC: H04M9/02
Filed: 1972-02-10
Abstract: 1363357 Multi-station systems STANDARD TELEPHONES & CABLES Ltd 10 Feb 1972 6234/72 Heading H4K In a "ring main" p.c.m. system a plurality of substations are connected into a closed loop unidirectional transmission line which line starts and terminates at a control station. The system described differs from that described in Specification 1,187,488 in the provision of a separate signalling channel so that substations only need to monitor this channel as the control station transfers any signals from a speech channel on to the signalling channel after retiming and regeneration. The control station also provides all synchronizing and operating tones, the latter being sent on speech channels as a predetermined digital code with one digit modulated. To make a call the calling substation seizes a speech channel which is marked as free by the control station and receives dialling tone on this channel. The number of the called substation is sent and this is put, together with the identity of the speech channel, on to the signalling channel. The called substation recognizes its identity code and locks on to the respective speech channel. Ringing tone is sent around the loop on this speech channel until the called party answers when speech between the parties can occur.  When the called substation is engaged it does not send the special code (inviting ringing) back to the control station and an engaged tone is sent to the calling substation. The calling data is continuously sent on the signalling channel since the transmitting store in the control station is reset only on receipt of the special code. Thus the system automatically provides a camp-on-busy facility. Each substation may be provided with a plug-in identity card so that the subscriber can be reached on any substation where his card is inserted.

Patent GB-1499752-A (GB)
Title: Apparatus for testing the functioning of a timing device
IPC: G05B19/048
Filed: 1975-02-14
Abstract: 1499752 Testing electrical apparatus SIE SOC ITALIANA ELETTRONICA SpA 14 Feb 1975 Heading G1U The timing device tested is of the type used in protective systems, which on receiving an input, gives an output to an alarm or protective relay while the input continues for longer than a predetermined duration. The timing device output is used to operate a device, e.g. a relay, which requires a signal at least of duration T r , to respond. In the apparatus, the control circuitry of the timing device is modified to provide 'subliminal' testing, i.e. an input of short duration (testing) causes the timing device to emit a pulse shorter than T r , which does not operate the alarm device. A normal 'fault condition detected' signal received at any time produces the correct output from the timing device. The timing device comprises mainly a counter C driven by an astable multi-vibrator whose frequency is adjusted by P. When counter C is full (equivalent to the minimum duration criterion Tt of the input I), output Q locks the oscillator output to a high level. Capacitor C2 charges sufficiently to operate the following threshold detector which, produces the beginning of the output U. The counter C is initially set to zero after a delay (R4, C4) from the beginning of the input pulse I. This delay is much shorter than T t , therefore during a test cycle in which the input pulse length C t  is also shorter than T t , the begining of U occurs when inputs I r , I, have already returned to zero. After a delay T3, due to R3, C3 and preferably equal to Ct, a signal AB appears, signal AU disappears, and since IR is zero, C" goes to a high level resetting the counter to zero and thus unblocking the oscillator with the subsequent disappearance of U which thus lasts for a time T3. With the next test pulse input, after the delay T4, IR appears removing C" and unblocking the counter C. With the removal of C", AB also disappears after a delay T 5  due to R5, C3. When I now ends, AU therefore appears, re-establishing the initial conditions. If the input pulse I (and thus I r ) lasts for longer than T t , zero when AB appears after T t  + T3, this does not change AU, therefore C" remains low and the oscillator remains blocked. Consequently the output U remains until the input (IR) disappears, changing C" to high and resetting the counter to zero. A monitor circuit (M), Fig. 1 (not shown), compares the actual time delay T t  produced under test with a predetermined value. By making the delay T3 and thus the test output pulse equal to C t , a number of timing devices can be tested in series, the output U forming the input I to the next device.

Abstract: 971,363. Electric selective signalling. S. G. DEHN. (Telecomputing Corporation). Feb. 20, 1962, No. 6564/62. Heading G4H. The invention provides a system for digitizing the output of a resolver, and comprises a reference signal which is passed direct, and also via the resolver, to a phase comparator, the output of the comparator being digitized. Means are provided to multiply the phase shift of the signals applied to the comparator and to digitize this to provide a second order measurement of the resolver displacement. Resolver 20, Fig. 1 produces a phase shift in a reference signal fed to it, and this signal is compared with the reference signal by unit 24. The resultant signal represents the most significant digit, which is displayed at 28. The phase shifted signal is also multiplied by ten at 30 and mixed with the reference signal, which has been multiplied by nine. After detection at 36 a signal is obtained which represents the second digit. Further multiplication of the phase shifted signal and mixing with the reference signal provides, upon detection, the third digit. In a second embodiment, Fig. 7, (not shown), there is means to correct for phase errors caused by the velocity of the resolver.

Abstract: 1,150,651. Tapwinding. T.M.M. (RESEARCH) Ltd. 11 May, 1966 [16 Feb., 1965], No. 6679/65. Headings D1D and D1N. A web 11 coming from a scutcher passes to be wound into a lap 24 on driving rollers about calender rollers 13, 14, 15, 16 and passes 22, 23 the axes of which lie in a plane inclined to the horizontal. The lap roller 21 onto which the web is wound has pressure applied to its ends by a pneumatic piston-cylinder arrangement 25. When a length measuring device initiates doffing rollers 22, 23 are accelerated to break the lap. Subsequently the pressure in arrangement 25 is reversed so that the piston rods rise and levers 31, operated by fixed cams 33, engage the ends of the lap roller 21 and push it forwards onto a tray 34. An empty lap roller 35 resting in front of driving roller 23 is then lifted by levers 36 onto the driving rollers 22, 23. During rotation of levers 36 the hollow interior of the perforated lap roller 35 is connected to the interior of driving roller 23 which in turn is connected by a duct 37 to a source of low pressure; this air flows into the lap roller and the engagement of the web thereon is ensured. After a predetermined time an electrical timing device returns levers 36 to their initial position and cuts off the suction to the lap roller. In an alternative form the suction is applied to the interior of roller 35 directly through a tube connectable thereto and not through the interior of roller 23. The calender roller stack 13, 14, 15, 16 is weighted by a pneumatic arrangement 19, 20. The Web is threaded therethrough by a plate 17 and a nozzle 18 which is operable from the front of the machine by a push button to direct a blast of air and oil mist onto. the web and force it between rollers 14, 15. Plate 17 and nozzle 18 may be replaced by a nozzle directing air between rollers 14 and 15 and' a further nozzle to direct air between roller 15, 16.
