Title: Improvements in or relating to television and like systems
IPC: H04N7/00
Filed: 1934-09-10
Abstract: 444,065. Television. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Sept. 10, 1934, No. 26016. Convention date, Sept. 9, 1933. [Class 40 (iii)] Relates to television systems, as disclosed in Specification 431,561, in which the synchronizing signals consist of reductions of the transmitted carrier to zero, and the picture signals vary upwards from a minimum value A. According to one aspect of the invention, the receiver is unresponsive as regards picture reproduction to received carrier below the minimum value A, so that interference from neighbouring transmissions is reduced. Preferably a valve is biassed to be blocked until signals exceeding the minimum value are received. According to another aspect of the invention, a plurality of transmitters operating on adjacent carrier waves and serving a common area have their carriers reduced to zero at the same times so that the synchronizing signals of one transmission are not subjected to interference from other transmissions. Preferably the transmitters are electrically or mechanically coupled, or derive their synchronizing signals from a modulated carrier wave which may also be used for sound transmission.

Title: An hydraulic injection adjuster for internal combustion engine injection pumps
IPC: F02M41/14
Filed: 1961-07-18
Abstract: 932,829. Reciprocating pumps. MOTORPAL JIHLAVA, NARODNI PODNIK. July 18, 1961 [July 19, 1960], No. 26059/61. Class 102(1). A hydraulic injection adjuster for fuel injection pumps for multi-cylinder I.C. engines, comprising a single pump unit with opposed pistons and a rotary distributer, the amount of fuel fed to the I.C. engine being regulated by spilling a variable part of the fuel delivered into an overflow conduit whereby the beginning of the effective delivery and hence the amount delivered to the injection valves is varied, is characterized in that automatic adjustment of the beginning of injection and the quantity injected as the speed of the pump increases, the spill regulating element remaining fixed, is obtained by throttling the fuel spilling off into the overflow conduit. In an injection pump for a two-cylinder I.C. engine, fuel passes through a duct 10, a radial intake 9, an axial conduit 8 in a rotor 1 driven by the engine, to a radial bore in which slide pistons 3 and 4 actuated by rollers 5 and 6 which are located in radial cut-outs in the rotor 1 and are in contact with a cam ring 7 fixed to a housing 2. Cam lobes on the ring 7 are displaced 180 degrees with respect to each other. When the pistons 3 and 4 begin their delivery stroke duct 11 registers completely with duct 12 or duct 13 each leading to an injector, and an overflow duct 15 registers with a bore 17 or a bore 16, in a rotatable control sleeve 14, only to a varying degree which is adjustable automatically, by means not shown, by varying the angular position of the sleeve 14 with respect to the housing 2. At low engine speeds fuel is delivered under slight pressure by the pistons to the overflow until the bore 17 or 16 is no longer in connection with the duct 15 after which the fuel is delivered to one of the injectors through duct 12 or 13. The pistons 3 and 4 are moved apart after delivery, firstly by centrifugal force and then under the pressure of fuel delivered to the chamber between the pistons. A throttle 18 provides automatic adjustment of the beginning of injection and the amount of fuel delivered, according to engine speed. The effect of the throttle on the fuel is relatively small at low engine speeds but increases with increases in engine speed, for a given position of the control sleeve 14, to result in the pressure of the fuel in the conduit 8 reaching the required injection pressure before the connection between the ducts 15 and 17 or 16 has been broken, and thereby cause the injection to begin earlier.

In order to determine the acceleration and torque produced in a particular servo-system by its control unit, the output from the unit 1, in the form of an angular rotation #, is fed into an auxiliary servo-system 3, and also into a network 26 which is the electrical synthesis of the particular servo-system, the acceleration in the output of the network 26 being indicated at 27 and its torque output at 29. The auxiliary servo-system 3 comprises a selsyn receiver 4, a unit 5 for correcting the error signal for phase and amplitude, a cathode follower 9, an amplifier 11 and motor 12 for repositioning the rotor of selsyn receiver 4 through a backlash absorbing device 17, until the error signal is removed. Negative feedback between the motor 12 and amplifier 11 is provided by a tacho-generator 18, whose output is added algebraically to the output from the cathode follower 9, giving a signal representing # which is differentiated at 25 to give ##, and fed to the network 26, so that the acceleration output from the servo-system image 26 is indicated at 27. A further network 28 transforms the acceleration output from 26 to torque, which is indicated at 29.

Title: Improvements in or relating to means for maintaining the motion of a train of wheelwork
IPC: F16H39/01
Filed: 1961-07-21
Abstract: 918,639. Spring motors. DEVON INSTRUMENTS Ltd., and SHORTT, W. H. July 21, 1961, No. 26586/61. Class 10. Apparatus for periodically re-engaging a maintaining spring for a train of wheelwork comprises a gas-operated motor and valve means for controlling a pressure gas supply to the motor the valve means being controlled to cause the motor to re-energize the maintaining spring periodically so that the train of wheelwork is substantially constantly driven. Gas under pressure is admitted through an inlet 25, Fig. 1, and a constriction 27 to a chamber 24, Fig. 2, closed by a diaphragm 20, thereby moving the diaphragm downwardly against the action of a spring 22 to tilt a bell-crank 35 into the position shown. In this position, the bellcrank 35 allows a T-lever 16 to be rotated about its pivot 15 from the position shown by means of a maintaining spring 17, whereby a pawl 12 causes rotation of a ratchet-wheel 11. Towards the end of this movement, a toggle-spring 33 snaps over and turns a valve-operating lever 32 about the pivot 15 to move a valve 28 quickly from the position shown to a position in which it vents the chamber 24 through an outlet 26. This allows the spring 22 to push the diaphragm 20 inwardly to its original position. The spring 22 also acts through the bell-crank 35 to return the T-lever 16 to the position shown, thereby reenergizing the maintaining spring. Toggle spring 33 snaps back to its former position, thereby reclosing the valve 28, whereupon the cycle of operations recommences. The ratchet-wheel 11 is coupled to a train of escapement-controlled wheelwork through a spring which maintains some driving force while the maintaining spring 17 is being re-energized. The wheelwork may drive the chart drum of a recording instrument.
