Title: Improvements in or relating to railway signalling and/or points control systems
Inventor: BROWN ANDREW
IPC: B61L19/14
Filed: 1951-02-16
Abstract: 721,355. Route-setting. STANDARD TELEPHONES & CABLES, Ltd. Feb. 8, 1952 [Feb. 16, 1951], No. 3819/51. Class 105. [Also in Group XXXVII] In a route-setting system the control key comprises a movable switch member which is set and held as by friction in any one of a number (including one) of switch positions each having associated therewith respective electrical contact means which are operated when the switch member occupies the associated position to prepare the system to set up the corresponding route and non- holding switch means which on operation after the setting, operates a further set of contacts to cause the route to be set if circuit conditions permit. As shown, a multi-position manual switch comprises a rotatable axially movable shaft 2 having a pin and slot connection with the indicator collar 9; a contact spring pile-up 14 in each of the respective angular positions of the shaft; a spring-pressed stud 28 carried in a sloping bracket 13 on the shaft 2 and riding over an undulating cam surface 26, 27, Fig. 2, on rotation of the shaft to bias the shaft, when the stud is located in the grooves 26, to predetermined angular positions; a spring plunger 17 on each spring pile-up riding up the sloping bracket 13 and into a shallow depression 23, Fig. 1, when the shaft is moved axially so as to hold the switch in that position and to control all springs in the pile-up to prepare the system to set up the corresponding route; a further set of contact springs 25, Fig. 1, common to all positions of the switch and operated to cause said route to be set, if circuit conditions permit, by a further axial movement of the shaft, rendered non-holding, when released, by the pressure of the springs 25 and by the spring pressure of the pile-up 14 exerted through the plunger 17 on the right-hand side of the depression 23; and inwardly projecting lugs 30 formed on the inner periphery of the switch body engaging with the end of the bracket 13 to prevent axial movement of the shaft when not in a predetermined position. The non-holding movement may alternatively be effected by a plunger housed within the shaft, Fig. 5 (not shown). In a circuit, Fig. 4, employing the control switch, the contacts rk1, normally open, are contained in the pile-up 14 and closed on the first axial holding movement of the switch. Contacts a or b will be open if for any reason the required sequence switch for the route setting is not available. If available, on the non-holding axial movement of shaft 2 to close contacts 25, relay RL operates to energize sequence switch control relay ssc which closes a stick circuit at contacts ssc1 to bridge contacts rh1 and to render the route setting independent of contacts 25. Relay RL may be dispensed with and its contacts replaced by contacts 25. Specification 520,580 is referred to.

Patent GB-1191991-A (GB)
Title: Improvements in and relating to Strap Feed and Tensioning Devices
IPC: B65B13/22
Filed: 1968-01-29
Abstract: 1,191,991. Strap-tensioning apparatus. SIGNODE CORP. 29 Jan., 1968 [31 Jan., 1967], No. 4533/68. Heading B8C. Apparatus for feeding a strap around a package, and for tensioning the strap, comprises two wheels around which the strap is guided. The first wheel is driven in one direction at high speed to feed the strap, and is then reversed to take up the slack. The second wheel is driven at a lower speed than the first in order to apply final tension to the strap. Strap 4 is drawn from a roll (2), Fig. 1 (not shown), by a feeding and tensioning mechanism 6 driven by a shaft 14 which is connected to a motor (12) through a clutch 16. A pinion 17, mounted on the shaft 14, drives a tension gear 18, which is geared on its opposite side to a further pinion 20, which drives a feed wheel 26 by way of a slip clutch 24 and a shaft 22. The strap is directed around the feed wheel 26 by pinch rolls 27, 29, and then enters a guide 30 which surrounds a tension wheel 32. The rigidity of the strap keeps it within the guide 30 and away from the periphery of the wheel 32 during feeding towards a package (10). When sufficient strap has been fed, the drive is reversed and the feed wheel pulls the strap back, taking up any slack. In so doing, the strap is brought into contact with the wheel 32 which is thus caused to rotate on its shaft 34, which is freely mounted at the centre of the tension gear 18 through an overrunning clutch 36 fixed on the gear 18. The tension wheel can thus rotate at the high speed of the feed wheel by virtue of the clutch 36. When the slack has been taken up, the torque on the shaft 22 acuses the clutch 24 to slip, and the speed of rotation of the wheels 26, 32 decreases until the clutch 36 locks, when the tension wheel 32 will be driven at this lower speed to apply further tension to the strap. At the required final tension, the clutch 16 is arranged to slip, and a ratchet 44 is engaged to retain the tension while the strap is secured by a mechanism (8) which may apply a seal or fuse together the overlapped portions of the strap.

IPC: G10H5/02
Filed: 1916-04-04
Abstract: 100,358. Forest, L. de. April 24, 1915. [Convention date]. Instruments with plates &c. electrically vibrated.-Electric oscillations generated by an audion and varied in frequency by means of a graduated series of resistances are employed for producing musical notes in a telephone receiver or an equivalent device. Two or more audions with their connected circuits may be associated. In the arrangement shown, the audion 1 comprises a filament electrode 4, two grids 3, and two plate electrodes 2. A variable capacity, consisting, for instance, of condensers 14, 15, 16, one. two, or all of which may be connected up by a switch 20, is placed in a circuit from the grids 3 through a transformer coil 10 to the filament 4. The other coil 11 of the transformer is in series with the plate electrodes 2, telephone receiver 8 or the like, main battery 7, and filament 4. A variable capacity 12 shunts the transformer coil 10 in the grid circuit, and the other coil, or the coil and receiver, may be similarly shunted. Between the grid and filament electrodes is a set of high resistances 22, preferably non-inductive, and consisting, for instance, of ground glass or streaks made by a hard graphite pencil. Taps from the resistances, which are adjusted .to produce a scale, lead to switches, preferably in the form of pianoforte keys of light touch. In a modification, the high resistances are in parallel, so that operation of two keys produces a note higher than that obtained with either key alone. The general pitch of the instrument is determined by the variable capacities. According to the Specification as open to inspection under Sect. 91 (3) (a) a continuous change of pitch may be obtained by varying a condenser, giving a siren note. This subjectmatter does not appear in the Specification as accepted.
