Filed: 1973-05-08
Abstract: 1436639 Remote reading of meters GAZ DE FRANCE 8 May 1973 [8 May 1972] 21957/73 Heading H3H  In remote reading of meters which actuate a switch upon passage of a predetermined amount of metered substance or devices which actuate a switch upon detecting a particular event, the switches are scanned by a MxN switching matrix which, connects successive groups of the switches into circuit, the switches in a group being each associated with a different valued resistance so that each different combination of switch states within a group produces a different overall group resistance, there being a further resistance in each group not associated with any switch for fault detection, an analogueto-digital converter 20 marks lines 27 0 -27 3 , Fig. 6, according to the states of the switches in the connected group, and half-adders 35 9 -35 3  compare the states on lines 27 0 -27 3  with the least significant bits of the accumulated totals for the respective switches, stored on a tape 28, a stored total being incremented by 1 if the compared states differ. Inputs.-The resistances of a group may be weighted in a binary sequence and connected in series or parallel (Figs. 1, 2, not shown). Each switch may be operated by an individual gas, water or electricity meter or device for detecting entry of burglars, or tampering with a connection box. Alternatively a group of switches may be in the form of a binary encoded position sensor (Fig. 3, not shown) the position may depend on pressure. Fault detection.-Open/short detector 21 detects when the combined resistance of a group is over or under an acceptable range and signals via OR gate 25 and inverter 44 to inhibit AND gates 41 in the half-adders thereby blocking further accumulation, the output of half-adder 35 4  causing a fault signal to be recorded on the tape 28 alongside the stored accumulated totals for the group concerned. Scanning.-As shown in Fig. 4 this is done by fast and slow switches 13, 14 and storage tape 28 is advanced in synchronism therewith. Fast and slow relay cards may be used instead (details, Fig. 10, not shown), these being interchangeable (e.g. M=N=32) for equalizing wear. A circuit responsive to the relay switching currents may be provided to detect "sticking".

Abstract: 464,019. Moulding rubber articles by dipping. SPANEL, A. N. Aug. 2, 1935, No. 21965. [Class 87 (ii)] A hollow rubber article having a reinforced edge is made by applying a coating of an aqueous dispersion of rubber to a form having a shoulder at which said edge is to be produced, and setting the dispersion on the form while the latter is so disposed that an accumulation of rubber is retained at the shoulder by surface tension against the action of gravity. An abrupt edge on the form serves to produce a line of weakness near the reinforcement, and the article is subsequently torn along this line. The article may also have edges defined by ridges of the 'teardrop ' type. The invention also comprises forms having shoulders and supporting means so disposed as to enable the process to be carried out. In the Figure is shown a rubber article having an edge 114 produced by surface tension at a boss 172, the line of weakness being obtained at an edge 173. The article is also provided with a tear-drop reinforcement 107. Specification 450,732, [Group XVII], is referred to.

Filed: 1952-09-02
Abstract: 732,137. Bobbin supporting devices. PLESSEY CO., Ltd. Aug. 31, 1953 [Sept. 2, 1952], No. 22033/52. Class 120(2). A bobbin supporting device comprises bobbin supports 3 movable into and out of a bobbin supporting position, a rotatable spindle 7 and a collar 15 mounted so as to be slidable in the axial direction of the spindle and means operable as a result of axial movement of the collar to effect rotation of the spindle to permit movement of the supports into or out of the bobbin supporting position. As shown bobbin support levers 3 are pivotally mounted on a pin 2 which extends transversely across the bore of a tubular sleeve 1. The sleeve 1 is provided with slots 5 through which the detent portions 4 of the levers 3 may project. Mounted within the bore 6 of sleeve 1 is spindle 7 which is axially displaceable and also rotat-  able during such movement. For this purpose the surface of spindle 7 is provided with eight  splines 8, 9, the four splines 8 being situated immediately above and between the four splines 9. The ends of each spline are saw-toothed providing upper and lower cam surfaces 10, 11 and a pin 13 is arranged in the bore of sleeve 1 to project radially into one of the grooves 14 between the splines on the spindle. The spindle 7 is adapted to be moved axially within the bore 6 by a collar 15 arranged exteriorly of sleeve 1 and axially slidable thereon, pins 16, which extend through slots 17 in sleeve 1, being provided to engage groove 18 in spindle 7. The spindle 7 is maintained in the lower position shown, by a compression spring 22. In this position abutment surfaces 20 engage the upper ends of levers 3 so that detents 4 are held radially apart in their bobbin engaging position. Upward axial movement of the collar 15 from this position causes similar movement of the spindle 7 and by engagement of pin 13 with cam surface 11 causes partial rotation of spindle 7. Return axial movement of spindle 7 to the lower position by spring 22 causes pin 13 to engage cam surface 10 to effect further partial rotation of spindle 7 such that slots 21 in spindle 7 now register with the levers 3 and the detent ends 4 of these levers are free to be moved radially inwards out of their bobbin engaging position. Further up and down axial movement of collar 15 when another bobbin is applied to the device rotates the spindle 7 to bring the abutment surfaces 20 on spindle 7 in register with the levers 3 to push the detent portions 4 outwards again into their bobbin supporting position. The device is adapted to be suspended by its upper end so as to be freely rotatable by a universal ball joint 27, 28, 29 on the lower end of a spigot 32 adapted to be fixed in a machine creel.

Load pulley 1A is driven by reciprocating handle 9A, the handle being furnished with two pawls which co-operate respectively with ratchets 7B and 7. When the load is to be raised, ratchet 7B is driven by the handle through its respective pawl, the ratchet being splined on to shaft 2 so that pulley 1A is thus directly driven and the load raised. The tendency of the load to fall is prevented by splines 53 formed in housing 1, backward rotation of the pulley causing ratchet 7 to screw itself along shaft 2 till plate 5 is gripped between ratchet 7 and backplate 3 fixed to shaft 2, the plate 5 having slots 2 engaging in the splines 6 of casing 1. When the load is to be lowered, ratchet 7 is driven by the handle through the other pawl so that ratchet 7 is screwed leftwards along shaft 2 to free plate 5 from splines 6, the alternate reciprocating strokes of the handle permitting the fall of the load in steps, each step terminating when the load has screwed the ratchet 7 till plate 5 is fixed by its splines. The back plate 3, alternatively, may be appropriately splined or screwed on to shaft 2. Handwheel 2C serves to free the clutch to permit freewheeling of the chain.

Title: Improvements in and relating to automatic railway signalling systems
IPC: B61L23/16
Filed: 1933-08-10
Abstract: 423,941. Railway signalling systems. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Aug. 10, 1933, No. 22411. Convention date, Aug. 29, 1932. [Class 105] The entry of a train into a section puts the signal to danger by dropping the track relay and an auxiliary relay, likewise dropped by the train shunt across the rails, cuts off the track circuit current; the auxiliary relay is picked up to resume the track circuit feed only when the train has entered the next section and protected itself by dropping the track relay of such section. A train in section A de-energizes the auxiliary relay 30 so that a stick contact 31 thereof opens the primary circuit of the feed transformer T for section A. When the train enters section B the track relay 10 of such section B drops and its back contact 11 closes the primary circuit of the feed transformer T for section A so that the auxiliary relay 30 of section A picks up and closes its stick contact 31 whereby section A continues to be fed after the train has left section B. The signals, such as lamps, are controlled by a track relay contact 12. The lamps may be supervised by making the auxiliary relay 30 a two-winding relay as shown in Fig. 2, one winding 33 being included in the lamp circuit so that on failure of a lamp the relay 30 will not pick up and thus the rear signal remains at danger. With a burnt-out lamp, a contact 34 prevents the rearward track circuit being energized, as it otherwise would be, during the time the track relay 10 is dropped and closing the contact 11. In the Specification as open to inspection under Sect. 91 it is stated that the auxiliary relay may be inserted in the current supply to the track circuit and used for approach energization of the track circuit, approach lighting of the signals, or for a normal danger signalling system. This subject-matter does not appear in the Specification as accepted.
