Title: Improvements in or relating to an Arrangement for Driving the Carriage of a Typewriter
IPC: B41J11/24
Filed: 1968-05-14
Abstract: 1,181,035. Typewriters. PAILLARD S.A. 14 May, 1968 [26 May, 1967], No. 22727/68. Heading B6F. In a typewriter, the carriage is driven for letter-spacing, back-spacing and carriage return by an electric motor (7), Figs. 1, 2, 5 (not shown), which exerts a continuous force on the carriage through a worm (6), gears (5, 4) and a rack (3), which force is opposed by one of two escapement catches 12, 13, Fig. 3, engaging teeth 11 on a second rack 10, the motor being normally supplied with reduced voltage and a pulse of increased voltage being supplied to the motor whenever the carriage is stepped. Letter-spacing.-Depression of the space bar energizes an electromagnet 23 and causes an armature 22 thereof to push upwardly on a projecting end 20 of the catch 12 (as shown), having a nose 18 engaging a tooth 11 of the rack 10. The nose 18 is disengaged from the tooth 11 and as the motor under increased voltage forces the rack 10 and hence the carriage in the the direction F 1  until the tooth 11 engages the nose 19 of the second catch 13. The catch 13 is pushed by the tooth so that the right-hand end of an elongate opening 15 therein engages a stud 16 which passes therethrough, and the projecting end 21 of the catch 13 is in position for engagement by the armature 22. The disengaged catch 12 is urged to the right by a spring 17, so that the end 20 is out of alignment with the armature 22. The motor is short-circuited before the tooth 11 engages a nose 18 or 19 to lessen the noise of engagement. Carriage-return.-For carriage return, the polarity of the electric motor is reversed to drive the rack 10 in the direction F 2 , Fig. 4, and an electromagnet 24, Fig. 3, is energized to disengage both catches 12, 13 from the teeth 11. At the end of the line a switch 36 is opened to decrease the voltage supplied to the motor, and a switch 59 later opens to deenergize a relay (D), Fig. 6 (not shown), which effects re-reversal of the polarity of the motor. The carriage return is initiated by closure of a switch (55, Fig. 6) which effects energization of relays (A, D, B) to operate switches which act to energize the electromagnet 24, reverse the polarity of the motor through switches (d 1 , d 2 ), Fig. 5 (not shown). Back-spacing.-Back-spacing is initiated by closing a switch (56, Fig. 6), thus energizing relays (C, D) which act to reverse the polarity of the motor, increase the voltage of the supply thereto, and energize an electromagnet 33, Fig. 4, to pivot a catch 27 into engagement with the teeth 11. The catch 27 is forced to the right by the force of the motor against a spring 32 so that a switch 34 is opened to end the cycle by re-reversal of the polarity of the motor. Back-spacing can be repeatedly effected by closure of a switch (60, Fig. 6) to activate a multivibrator (61) which repeatedly energizes the relays (C, D).

Void [Published under Sect. 91 of the Acts]. [Class 7 (iii.).] To facilitate dismantling, the float chamber cover is formed integrally with the mixing chamber, the float chamber which contains the fuel and aerating-air passages being secured to the cover by bolts and applied laterally against the mixing chamber. The mixing chamber 1 of a downdraught carburetter has a Venturi tube 6, an air throttle 4 and a mixture throttle 7. The float chamber cover 5 is in one with the mixing chamber and, by means of bolts, supports the float chamber 8 to which is attached by a vertical joint 71 a block 14 which enters slots 15, 16 in the body 1 and Venturi tube 6 respectively. The block has fuel and air passages 32, 36, 37 and carries at its upper end the emulsion nozzle 10. The float chamber contains an accelerating pump consisting of a barrel 17, and piston 19 with collar 59 loaded by a spring 61. The piston is actuated from the throttle through a lever 63. The lower end of the piston has orifices controlled by a disc valve 22. The lower end of the barrel has a spring-loaded valve 26 whereby fuel may be discharged to duct 24, but it may also reach this duct through duct 28 and calibrated orifice 29. The duct 24 communicates with the nozzle 10 through calibrated orifice 30 and ducts 31, 32. The float chamber also communicates with nozzle 10 through duct 33, calibrated orifice 34 and ducts 35, 36. Aerating air is admitted to duct 36 through ducts 37, 38 the latter opening at 39 into the upper part of the float chamber. Ducts 36, 37 may communicate at different levels through openings such as 40, 41, 42. Duct 38 may also supply air to duct 32 by duct 43 and orifice 44. Idling fuel is fed from duct 37, past orifice 46 and is mixed with air on entering orifice 47 and radial ducts 49. The emulsion is diluted with air controlled by valve 53, and is then conveyed through duct 57 to orifice 58 near the throttle valve 7. The connection of the float chamber to a horizontal carburetter is shown.

Abstract: 504,247. Valve amplifying circuits; impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 2 1938, No. 22880. Convention date, Sept. 30, 1937. [Classes 40 (iii) and 40 (v)] In amplifiers of the type comprising parallelconnected channels coupled at the output through an impedance-inverting network, the channels providing normal and peak amplification separately, distortion due to phase shift of the side-bands in the phasing circuits in the input of the amplifier of one channel is compensated by producing a similar side-band phase shift in the other channel. The two channels B and C of the modulated carrier amplifier consist of valves 5, 6, with the common output circuit 7. Valve 5 is biassed to cut-off and provides amplification of waves up to the carrier level. Valve 6 is biassed beyond cutoff and amplifies the modulation peaks. Valve 5 is connected to the output circuit through an impedance-inverting network 10 which introduces a 90‹ phase change and permits the valve 5 to carry an increased portion of the load when valve 6 commences to operate. The common input circuit 8 supplies modulated carrier through the 90‹ phase-shifting network 11 to the grid of valve 5. The grid tuned circuit 13, provided to maintain a high input impedance, causes an undesirable side-band phase shift on either side of the 90‹ shift provided by the network 11. The grid of valve 6 is fed through a circuit 15 comprising two networks 16, 17, in cascade which produce a total phase shift of 180‹ ; a tuned circuit 18 is inserted between the networks to introduce in the channel C a side-band phase shift similar to that occurring in the channel B. As a result of the equal side-band phase shifts no resultant distortion of the modulation envelope occurs. In a modification of the circuit arrangements, Fig. 4 (not shown), the common input circuit is detuned to provide the first filter coils of both channels and the other parallel inductances are replaced by single coils. Specification 471,423 is referred to.

Abstract: 1,034,119. Selective signalling. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. June 1, 1964 [June 10, 1963], No. 22992/63. Heading G4H. In a system of communicating between a central station and any one of a plurality of field stations over a common channel, means are provided for preventing the initiation of a transmission if one is already in progress. Transmissions can be initiated either by the central station or by a field station. Data is transmitted as a pattern of bits, the " one " bits being represented by a first frequency and the " zero bits by a second frequency. Adjacent bits are separated by a neutral third frequency. A central station transmission, Fig. 4, commences with a long pulse S of the first frequency Ofe which seizes the transmission channel and prepares each field station for reception. This is followed by three bits V, W, X, identifying the field station being called, and by three control bits Q, P, KS. During the bit KS the called field station (assuming no faults have developed) applies the neutral frequency Ffn to the channel which signifies to the central station that it is ready to receive data and which also stops other field stations initiating a transmission. The data, comprising bits TO to Tn and TP (parity) is then transmitted and is followed by a unique end of message signal EC, the reception of which causes the field station to transmit the frequency Ffd. Normally, a field station only transmits when any change occurs, but by use of the Q bit the central station can call upon any field station to transmit the states of the equipment thereat at any time. The P bit is a parity bit. Transmissions by field stations are preceded by their identity code. If two field stations commence transmitting simultaneously resulting in a garbled message being received by the central station both transmissions are cancelled and each field station has to start again. To reduce the possibility of a subsequent simultaneous transmission each field station includes a random pulse generator and cannot start again until it has produced a pulse.
