Patent GB-673106-A (GB)
Title: Centralized street signalling system
IPC: G08G1/081
Filed: 1949-09-12
Abstract: 673,106. Road signals for controlling traffic. TELEFONAKTIEBOLAGET, L. M. ERICSSON. Sept. 12, 1949. [Sept. 24, 1948] No. 23520/49. Class 118 (ii). Signals indicative of the operation of road pads are transmitted from a crossroads over a two-wire line to a central station and signals to control the traffic lights are sent from the central station over the same two wire line to the crossroads. At the crossroads, the road-pad contacts DA or DB in the blocked road are connected by relay R10 or R11 to relay R7 and the contacts in the free road to relay R9. Assuming road A to be blocked, the operation of contacts DA energizes relay R7 which locks up and short-circuits the lower winding S2 of a polarized relay R6, this short-circuit being completed over front contacts of a slow-release relay R8 (released by relay R7) in case relay R9 is operated at this time. Relay R6 is connected over twowrie line La, Lb and contacts of a reversing relay R2 to the windings of a marginal relay R3 at the central station. On the short-circuiting of winding S2. relay R3 responds, energizing relay R4, which locks and opens the operating circuit of a relay R5. Relay R5 is made slow to release by a condenser C and is held over its locking circuit including back contacts of relay R3 as long as the interval between vehicles in the free road B is not greater than the release time of relay R5. When this relay releases, relay R2 operates over its lower winding, reversing the battery connections to conductors La, Lb, so that relay R6 responds to change the signal lights, at the same time operating relay R11 and releasing relay R10 whereby relay R7 is released and the connections between contacts DA, DB and relays R7, R9 are changed over. Relay R2 releases relay R4 and locks in series with the lower winding of relay R1 which re-operates relay R5. With road B now blocked, contacts DB control relays R7, R3, R4 in the manner described above and when relay R5 releases, the upper (opposing) winding of relay R2 is energized and the relay releases to send a further reversal over the line La, Lb. Relay R1. also releases and the cycle of operations as described is repeated. Opening of contacts K at the central station causes relay R6 to assume a neutral position in which all lamps are extinguished. An overall control of the signal lamps can be effected from the central station by connecting positive potential directly to the upper armature of relay R1. Telephone communication may be effected over the line La, Lb in a simplex circuit without interference with the signal control operations.

Filed: 1934-08-16
Abstract: 442,876. Chimney - shafts. CLARKE, H. F., Snowdon Road, Middlesbrough. Aug. 16, 1934, No. 23654. [Class 25] In a chimney-shaft h having a lining formed in sectional lengths b, c .. , each separately supported on an internal ledge g, a portion e at the lower end of each lining section is enlarged outwardly and downwardly and the upper end of the adjacent lower length of lining fits or telescopes thereinto. As the lining becomes heated by the passage of hot smoke or gases, the main portion d of a lining section such as c will expand uniformly while the lower enlarged portion e, being protected by the upper end a of the section b will have an expansion decreasing from a point opposite the top a of the section b to the lower end f resting on the ledge g. As a result of such expansion the whole of the section will become substantially cylindrical when hot and when cold will resume the form shown in the Figure. The lower ends f will not move laterally on the ledges g and consequently no lateral stresses will be applied to the shaft h. Protecting ledges m prevent the passage of dust into the annular spaces k between the shaft and the lining sections.

The coupling ring 21 has radial spokes 24 which pass through axial slots in a driving clutch bell 14 and through recesses 17 in the synchronizing rings 16. Baulk surfaces 26 on the spokes 24 coact with baulk surface 19 on the synchronizing rings to prevent engagement of the spokes 24 of the coupling ring with the clutch teeth 6 1 , 9 1  until synchronism is attained. When the coupling ring 21 is in its central, neutral, position it engages the groove 29 in the thrust sleeve 27 and holds the synchronizing rings 16 disengaged from the friction surfaces 6 2 , 9 2  When, on synchronism, the coupling ring moves into engagement with the clutch teeth it rides up the outwardly flared portion of the thrust sleeve 27 and thus maintains the synchronizing ring 16 in engagement with its co-operating friction surface. The double positive clutch may be incorporated in a two-speed gear associated with a main change speed gear.

[Class 40 (i)] [Also in Group XXIV] In a system of remote control for positioning a plurality of shafts, more particularly the control shafts of a plurality of circuit elements for effecting wave changes in a radio transmitter, the shafts 9 (only one of which is shown) are driven by a common motor 1 through flexible shafts 8 and friction clutches 7 by gearing 6 and are provided with angularly and longitudinally adjustable abutment members 10 which co-operate with adjustable stop members 13 to determine the positions of the shafts. The members 13 are set in predetermined positions under the control of a common motor 17 and a selector switch system 18. The motors and switch system 18 are controlled in such a manner that the following sequence of operations is effected: ( 1) the motor 1 is operated to restore all the shafts 9 to their zero positions ; (2) the motor 17 operates the stop members 13 into positions determined by the switch system 18 ; and. (3) the motor 1 is again operated to rotate the shafts 9 until the abutments engage the stop members. Before being stopped, the motor 1 is allowed, by the friction clutches, to over-run the shafts and tension a spring 4 so as to maintain the abutments in engagement with the stops. The rack and pinion drive 11, 12 for the stops 13 may be replaced by the gearing shown in Fig. 2, which comprises a slide 27 carrying a stop 13 (not shown) and a projection 29 engaging a threaded shaft 19 which moves the slide longitudinally at alternate half revolutions. The thread is formed by parallel grooves 25 and helical half-turns 24 of the same pitch provided respectively on semicylindrical members 21, 20 which are separated by longitudinal grooves 23.

Convention date, Aug. 24, 1933. [Class 135] For adjusting a valve such as a relief valve on a tyre inflating device, the exposure to pressure of the pressure actuated member is varied. A pump nipple 1 has an air passage 2 in which is secured a tube 3 screw-threaded at its rear end. A valve 5 is normally held against a flat valve seat by a spring 6 to prevent escape of air through ports 12 in the tube 3. The spring 6 is initially adjusted to the approximate desired loading by a nut 8 which is then soldered in position. Fine adjustment of the blow-off pressure is effected by radially movable sections 11 of the valve seat by which the area of the valve 5 exposed to pressure is varied, the sections 11 having pins 13 engaged by a scroll groove 15 on a ring 14 which is turned by a sleeve 19 having a scale 25. The sleeve 19 is held in position by a sleeve 17 screwed on the end of the tube 3, a pin 22 engaging a pin 23 on the ring 14 to confine the adjustment to one revolution of the ring. Passages 26 allow air to escape from the sleeve 17. According to the Specification as open to inspection under Sect. 91 adjustment may be effected by a disc swingable to and fro upon the valve surface. This subject-matter does not appear in the Specification as accepted.
