Title: Electronic telegraphic system
IPC: H04L25/49
Filed: 1961-08-28
Abstract: 960,273. Telegraphy. C. D'EVELYNES. Aug. 28, 1961 [Sept. 14, 1960], No. 30991/61. Heading H4P. Two systems are described for remotely controlling a plurality of electric typewriters of the type described in Specification 960,272 which,is referred to. In the first system. Fig. 1 100 typewriters are sequentially controlled the arrangement being such that in a complete cycle of the system each typewriter is given the opportunity of printing one character (or executing one function such as " space Timing is effected by a character timer comprising multi-cathode tubes 39, 40, these being arranged to have a 20-position cycle-that is first tube 39 advances 10 steps while tube 40 rests in its zero state, and then tube 40 advances 10 steps while tube 39 rests in its zero state- and a typewriter timer comprising multicathode tubes 41, 42, these being arranged to select the 100 typewriters sequentially and to advance one step after each character cycle. Each typewriter has associated with it 14 thyratrons arranged as two groups of 6 and 8 (only two 32, 33, one from each group of typewriter No. 00 being shown in the drawing) and in order to print a character it is necessary to fire one tube from each group (giving 48 possibilities). This is effected by using 14 of the 20 sequential pulses from the character timer 39, 40 to sequentially prime the 14 thyratrons of a typewriter and by applying the signal representing the character it is desired to print-this signal being in the form of two differentially timed pulses-to all 14 thyratrons, whereby the coincidence of timing and date pulses causes the firing of the appropriate thyratrons. As shown, each character to be printed is received 20 as a long pulse which is differentiated 27 and shaped 30 to produce two pulses which are applied, via a reactor 37, to the typewriter thyratrons, such as 32 and 33. Received data is also said to effect synchronization of a local oscillator 25 which advances the timing circuits. In the second system (Fig. 6, not shown) each character cycle has 50 positions, each typewriter has 15 thyratrons and data is represented by a single pulse differentially timed in the cycle of 50. It is stated that a similar arrangement could be used as a transmitter and also that a cyphering unit could be included.

Title: Shock absorber for power driven vehicles
IPC: F16F9/22
Filed: 1924-12-29
Abstract: 235,788. Moldenhauer, E. Dec. 29, 1924. Dashpots. - A shock-absorber for vehicles is arranged to damp only those movement's which occur below the normal position of equilibrium of the wheel axle, the shock-absorber automatically adjusting itself to the positions of equilibrium due to various vehicle loads. As shown, the shock-absorber comprises a fluid chamber integral with an arm attached to the wheel axle, while the other arm is adapted to rock an arm 8 to operate pistons in the chamber. A brake piston 9, provided with a non-return valve 12, is arranged inside another piston 11 and connected to it by a spring 13, a groove or recess 15 being provided in the piston 11 of such a length that it extends to both sides of the brake piston 9 in the position of equilibrium of the shock-absorber. To and fro movement above the position of equilibrium of the wheel axle, i.e. to the right of the brake piston 9, are freely allowed bv the valve 12 and recess 15. On the brake piston 9 moving to the left of the position shown, the end of the recess 15 is passed or covered so that the brake piston 9 moves the piston 11 through the thrust of the spring 13, the movement of the piston only being permitted to occur slowly by reason of the small aperture 14. The return movement of the piston 9 is permitted by the valve 12 and drags the piston 11 until at the position of equilibrium the recess 15 is uncovered and continued movement is freely permitted. When the vehicle load is altered, the piston 9 takes up a fresh position and the drag or thrust of the spring 13 causes the piston 11 to move slowly until it is again brought to the same distance away from the piston 9 as before, so establishing a new position of equilibrium of the shock-absorber.

Title: Improvements in or relating to prepayment apparatus for telephone systems
IPC: H04M1/677
Filed: 1936-11-16
Abstract: 485,117. Substation equipment. ENGEL, H. Nov. 16, 1936, No. 31297. Convention date, Nov. 16, 1935. [Class 40 (iv)] [Also in Group XVIII] At a prepayment substation, a number-selecting device and a coin-receiving device are interconnected by control means which permit the transmission of selecting impulses by the numberselecting device only when the amount prepaid corresponds to the fee chargeable for the number selected. As applied to apparatus in which the number selector has a lever for each digit the four levers which select the code number determining the charge are connected with respective insulating segments L, M, N and O passing between pairs of contacts interposed in a series of parallel circuits arranged between a motor D operating the impulse transmitting mechanism and an arcuate series of contacts engaged by a contact arm c of a coin-summating mechanism S. When, as shown, there are six rates of charge, six parallel circuits are provided, and six arcuate series of ten holes (corresponding to the digits 0-9) are provided in each of the segments. Contact elements are inserted in certain of the holes in such a manner that, when a number is selected, the four pairs of contacts of the appropriate one of the six parallel circuits are closed. If the correct value of coins is inserted into the apparatus, the coin summating mechanism S advances its contact arm c to engage the contact connected to the circuit completed by the segments L, M, N and O, and the motor D is energized to transmit the selecting impulses for completing the connection. A second contact arm a of the coin summating mechanism S moves over contacts to transmit audible impulses to the exchange to enable the operator to check the amount inserted for non-automatic calls. Different coins are inserted into separate slots and are received by corresponding inclined plates X, Y and Z on a counterbalanced rocking arm P. Each coin depresses the arm P until it rolls back off the plate X, Y or Z, the inclinations of the latter being so adjusted that the rotations of the arm P are proportional to the three coins. The rotation, or successive rotations when coins are inserted in succession, are transmitted through a one-way-drive ratchet and pawl to the contact arms a and c, which consequently assume a position corresponding to the total value of coins inserted. The contact arms are restored when the receiver is replaced. Relay contacts n connected between pairs of the contacts engaged by the arm c enable the charges to be reduced, at night time for example.

Member 10 is oscillated by a roller 13 which engages a slot 12 and is mounted on a ball-bearing carried eccentrically by a disc 24. The motor 2 drives the axles 16, 20 through a worm 14 and worm-wheel 15 and gears 17, 18, 19. A worm 21 on the axle 20 drives a worm-wheel on the shaft 23 which carries the disc 24. A number of alternative tapped holes of different eccentricities are provided in the disc 24 to receive the ball-bearing journal of the roller 13, to permit adjustment of the amplitude of oscillation. The frequency of oscillation can be varied by changing the ratio of the reduction gearing. An additional set of blades 4<SP>1</SP>, separated from the blades 4 by a baffle 26, may be provided, to give an upwardly directed current of air. It is stated to be known to vary the inclination of the axis of the fan each time it reaches the end of its run; or to provide stops at intervals on the track which strike the carriage to change the direction of the axis of the fan or of fan nozzles. It is also known to mount two fans on a carriage, arranged laterally and inclined in relation to the track, the inclination being varied automatically.
