Title: Improvements in the manufacture of tubes of cement-asbestos or of similar substances
IPC: B28B21/48
Filed: 1921-03-02
Abstract: 159,832. Mattei, D., and Mazza, A. March 2, 1920, [Convention date]. Moulding pipes and tubes; moulding pulp.- Cement-asbestos and like pipes are moulded on a roller 20 from pulp led thereto on an endless band from vats 1. The usual drying means are provided and squeezing rollers 13, 13<1> are added for further drying the mixture before it reaches the roller 20. The upper roller 13<1> is weighted and kept clean by a travelling band 14. The pipe is formed by pressure applied by a travelling band 32 and rollers 21. The band drives the rollers which are so journaled that they move outwards in curved or straight guides as the pipe thickness increases, thus reducing the applied pressure. The rollers 21 are supported in a frame which can be raised to the dotted line position to allow removal of the finished pipe.

Title: Automatic safety circuit-breaking device for vehicles
IPC: H01H35/02
Filed: 1934-03-06
Abstract: 422,372. Gravity and inertia switches. RODEL, G. M. J., 227, Avenue de Tivoli, Le Bouscat, Gironde, France. March 6, 1934, No. 7135. Convention date, Aug. 18, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 10, 1934.] [Class 38 (v)] In a safety switch for motor and other vehicles, of the type in which a pendulum controls a circuit-breakeradapted to disconnect the electrical systems in the event of an abnormal inclination of the vehicle or a collision, the heavy mass of the pendulum is constituted by the storage battery 31 of the vehicle. The battery is mounted on arms 29, 30 rigidly secured to arms 25, 26 carrying the circuitbreaker, the battery and circuit-breaker being pivotally and slidably mounted on a rod 20 secured to fixed brackets 21, 22. The movable contact 6 of the circuit-breaker is carried by a leaf spring 5 and is normally held in engagement with the fixed contact 7 by a plunger 9 which is restrained from movement by a stop 19 secured to the rod 20. On abnormal tilting of the vehicle the plunger 9 escapes from the stop and the circuit is opened by the spring 5. The same effect takes place if the motion of the vehicle is suddenly arrested, when the storage battery and circuit-breaker proceed on their course by inertia until the plunger 9 escapes from the stop at one of the edges a, b. The Specification as open to inspection under Sect. 91 comprises also modifications in which the storage battery does not constitute the heavy mass of the pendulum. In one construction, Fig. 2 (Cancelled), the pendulum comprises a weight 16 carried by a rod 15 secured to the plunger 9 which engages the spring 5 carrying the contact 6. The contact 6 is normally held against a contact 7 by the engagement of pins 13 on the plunger with the cover 2 of the casing 1, but when the vehicle is tilted through a predetermined angle, the pins 13 enter slots 12 in the socket 10 carrying the plunger, and the spring 5 is released. In another construction, Fig. 4, (Cancelled), the pendulum weights 16<1> are carried by the bent end 23a of a rod 20 slidably mounted in fixed supports 21, 22 carrying the switch casing 1<1>. The plunger 9<1> is normally held in the position in which the contacts 6<1>, 7<1> are in engagement by a stop 19 on the rod 20. The plunger escapes from the stop either on tilting of the vehicle or in the event of a sudden impact, when the pendulum tends to proceed on its course by inertia, carrying with it the rod 20 and stop 19. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1928-03-07
Abstract: 313,113. Automatic Telephone Manufacturing Co., Ltd., and Beale, C. E. March 7, 1928. Automatic exchange systems.-An exchange of the relay type with junctions to a step-by-step exchange has switches OPS which keep idle feed circuits associated with idle outgoing junctions and switches IPS which keep idle incoming junctions associated with idle feed circuits. Outgoing call. A calling line is extended to an idle feed circuit 61, 62. If a digit is dialled signifying the step-by-step exchange a marker (not shown) momentarily grounds wire 10 and connects battery to wire 11 to energize relay ST, which locks in series with FB over 26, energizes K, disconnects the circuit 61, 62 from feed relay FA and extends it over OPS to the repeating relay OA of the pre-selected junction 74, 75. Ground from 25 steps idle switches OPS to find the next idle junction but magnet DMI of the engaged switch is disconnected by K. Further digits are repeated by OA to the step-by-step exchange. When the calling subscriber hangs up ST is unlocked at 25. All junctions busy. Relay JB is energized in a chain circuit and disconnects ground 77 so that the switches OPS stop on their last terminals. If a subscriber now calls, relays TA, TB are energized, tone is sent back from 76, and all idle switches OPS are again set hunting by ground from 36. Incoming call. A relay T is normally energized over 44, 45, 15, 47 in series with the lower winding of relay BM in the pre-selected feedgroup. When a call arrives over junction 40, 41, relay IA is energized and shunts T to energize BM, which closes a circuit through FB over 54, 53 for IB, which extends the junction over 61, 62 to relay FA in the feed-group. Relay FG cuts out BM and keeps FB, IB locked and IA is locked in a local circuit 65. Further digits reach the relay FA and the connection is completed in known manner. When the calling subscriber hangs up, relays FA, FG, IB, IA fall back. The pre-selective hunting of the switch IPS is controlled by relay T, which is energized over 44, 45, 15, 47 when an idle feed group is reached, this circuit being open at 15 if the feedgroup is engaged in an outgoing call or at 47 if engaged in an incoming call. All feed circuits busy, The FB relays, which are energized when a feed circuit is engaged in either an outgoing or incoming call, close a chain circuit to connect a low-resistance relay BH to the last terminal in the bank of wiper 44 so that idle switches IPS stop in this position. If a call now comes in from the step-by-step exchange the shunting of relay T at 50 energizes BH which closes a circuit for IB at 67; relays IT, TH are energized, tone is sent back from 69. and the circuit of BH is opened at 72 to start all the idle IPS switches hunting again. Two-way junction working may be effected by connecting the junction over front and back contacts of relay OB to wires 74, 75 and 40, 41.
