Abstract: 1507796 Pulsators for milking machines ORION MACHINERY CO Ltd 30 July 1976 [5 Dec 1975] 31770/76 Heading AIM The milking machine pulsator described in Specification 1495621 having a housing with a pair of diaphragms 8, 10 on either side of a partition 9 having an adjustable aperture 15 to provide interconnected chambers 13, 14 which are filled with liquid and control the rate of reciprocation of the diaphragms under the influence of alternating vacuum and atmospheric pressure an chambers 7, 11, is modified by the provision of means for removing air, which has leaked into chamber 13, from this chamber. This is effected by a pasageway 39 leading from near the top of chamber 13 to the aperture 15 so that any air in chamber 13 is transferred to chamber 14 during leftwards movement of the diaphragms. Removal of air from chamber 13 is desirable since air in this chamber gives rise to fluctuations in the pulsation frequency of the pulsator, the regulating valve of which is connected to diaphragm 8 bounding chamber 13, whereas air in the other chamber 14 has little effect on the frequency.

Title: Improvements in or relating to circuit arrangements for energising loads
IPC: H03K17/18
Filed: 1962-08-20
Abstract: 1,011,547. Selective printing. F. H. SHEPARD. Aug. 20, 1962 [Aug. 21, 1961], No. 31888/62. Heading B6F. [Also in Division H3] In a high-speed printer of the type described in Specification 825,646, 190 solenoid controlled type-hammers are each controlled by a separate transistor circuit (see Division H3), all energized from a common D.C. power supply. The capacitor 14 of each circuit is normally charged from a common supply 22 via transistor 16. When it is desired to operate any hammer, a pulse is fed via terminal 46 to a pair of transistors 32, 30 which arrange for transistor 24 to be turned on, discharging capacitor 14 through the appropriate solenoid 12. Transistor 16 is turned off during this time so as to isolate the capacitor 14 and solenoid 12 from the common power supply 22. This conductive state continues until capacitor 40 has discharged, when all four transistors are automatically restored to their original state. The printer contains type wheels mounted side-byside in the form of a cylindrical drum carrying alpha-numeric characters around their peripheries. The assembly is rotated at 1,200 r.p.m. and the paper moves step-by-step, each step occupying 10 to 15 milliseconds. Each hammer takes the form of a long, thin rod which is electromagnetically impelled upwards against the paper to press it for 50 microseconds against a selected one of the characters around the rim of the corresponding type wheel. Specification 825,646 is referred to.

Title: Web speed control system
Inventor: LAUKAITIS JOSEPH FRANCIS
IPC: H02P23/00
Filed: 1969-06-26
Abstract: 1,273,009. Automatic speed control. EASTMAN KODAK CO. June 26, 1969 [June 28, 1968], No. 32330/69. Heading G3R. In a web winding apparatus, e.g. for winding lengths of photographic film from a large reel 10 on to individual small spools 14, a first train of pulses is produced, e.g. by a photo-electric tachometer generator 18, whose duration represents the linear speed of the web 12; a further train of pulses of fixed duration is produced each pulse of the first train initiating a pulse of the further train; and a capacitor 30 controlling the speed of a take up motor 16 driving the spool 14 is arranged to be charged up through a first resistance 38 (to increase motor speed) while the first pulses are longer than the fixed duration pulses and to be discharged (to reduce motor speed) through a second resistance 36 when they are shorter. The speed pulses are applied to an amplifier 46 having two antiphase outputs. One output triggers both a bi-stable 52 and a monostable 54. After a time, pre-set by resistor 56 and representing the desired web speed, the monostable resets the bistable. The two outputs of the bi-stable 52 are compared with the two outputs of the amplifier by AND gates 62, 68 and other AND gates 64, 66 are opened to connect the capacitor through resistors 38, 36 to a supply V or ground respectively if the speed pulses are longer or shorter than the bi-stable pulses respectively. Transistor circuits for the amplifier, bi-stable, monostable and gates are described, Fig. 4 (not shown). A start switch is included which applies a starting pulse to set the circuit in operation (before the tachometer issues pulses) and to short the capacitor 30 ensuring a smooth start from standstill.

Title: Improvements in or relating to automatic control mechanism
IPC: G05B11/01
Filed: 1955-11-14
Abstract: 822,896. Automatic control systems. SILVA, L. M. Nov. 14, 1955 [May 9, 1955], No. 32472/55. Class 38 (4). In a system in which any difference between a controlled and a controlling variable is applied through a limiting amplifier to automatically regulate the controlled variable, feedback is applied from the output to the input of the amplifier through a composite network including an element having a time lag related to the delay between initiation and detection of the regulation. In Fig. 7 deviations from a desired value of the pH value of a fluid flowing in a pipe 50 are detected by electrodes 53 the output of which determines the position of a valve 56 so that the supply of reagent from a tank 57 is adjusted to correct the pH value. The difference between the direct voltage output from electrodes 53 and a reference voltage obtained from a potentiometer 71 is applied through an interrupter switch 74 to a thermionic valve A.C. limiting amplifier 66 the output of which energizes one phase of a two-phase servomotor 55 adjusting valve 56. To counter the effect of time-lag due to the fact that adjustments of valve 56 are not immediately detected by electrodes 53, a portion of the output of amplifier 66 is rectified by an interrupter switch 77, synchronous with switch 74, and applied as feedback through a resistor 84 and a thermionic valve D.C. amplifier 90 to a second contact of switch 74. This feedback is cancelled after a time equal to the above-mentioned time-lag by opposed feedback produced through a magnetic delay unit 83. Control systems, Figs. 11-17 (not shown), having additional feedback paths, feed-forward paths, and/or elements introducing additional transfer functions, including integral and differential functions, are described with the aid of block diagrams. Specification 813,262, [Group XXXVIII], is referred to.
