Title: Starting and stopping of a motor controlled by electrical pulses
IPC: G06F7/68
Filed: 1973-09-05
Abstract: 1446474 Automatic frequency control FUJITSU Ltd and FUJITSU FANUC Ltd 5 Sept 1973 [5 Sept 1972 13 Sept 1972 20 Oct 1972 (2)] 41862/73 Heading H3A [Also in Divisions G3 and H2] Apparatus for providing driving pulses PO to a stepping motor is arranged that under equilibrium conditions the frequency of the output pulses PO equals that of input pulses Pi and that the response of the frequency of the output in response to a stepped change in the frequency of pulses Pi may be linear, exponential or both, the response time of the motor being thereby controlled. The embodiment shown comprises a first up/down counter 1, the input pulses Pi being applied to an incrementing input thereof, a comparator 2 for comparing the count at 1 with that at a second up/down counter 3, and "UP" or "DWN" signal being provided depending upon whether the count at 1 is greater than that at 3 or otherwise respectively. The signal from comparator 2 causes pulses from an external source having a frequency F1 to be counted up or down at 3 by enabling one of two AND gates 5, 6. The numerical output from counter 3 is multiplied at 4 by a frequency F2 from a further external source and a frequency PO is provided to the motor and these pulses are also fed back to the decrementing input of counter 1. A full mathematical treatment is given in the Specification and it is shown that the shape of the response curve of the frequency of pulses PO in response to step changes in the train Pi is dependent on the relative values of F1 and the frequency of pulse Pi. The multiplier 4 may be replaced by a D/A converter (7), Fig. 9 (not shown), controlling a voltage controlled oscillator (8), or the counter 3 may be connected to an adder (21), Fig. 10 (not shown), whereby at each pulse in a train of frequency F2 the count at 3is added to that in aregister (22) and overflow pulses are produced by this register. In a modification, Fig. 12 (not shown), the counter 1 is connected to an adder, register arrangement (31), (32) of the type described above to give an output frequency proportional to F1 times the count at 1. This frequency is compared with that of the pulses PO at (35) to provide the "UP" and "DWN" signals to the gates 5, 6 controlling counter 3.
Patent GB-419059-A (GB)
Abstract: 419,059. Time-alarm signals. FERRANTI, Ltd., and HOLMES, W., Hollinwood, Lancashire. Feb. 27, 1933, Nos. 5886/33 and 6457 /34. [Class 118 (ii).] In an electrically driven clock wherein the alarm is released every twenty-four hours, two independent alarm-arresting means are provided one of which is temporarily operative at will after release of the alarm and when so operated is subsequently put out of action automatically by the other arresting means. The invention is described as applied to a synchronous motor clock, the alarm consisting of a vibrating reed k, Fig. 2, actuated by the magnet o, Fig. 1, which may also drive the motor rotor u. The reed is pivoted to a polepiece n and its free end is normally pressed against the pole piece v by a twenty-four hour cam b acting through resilient levers c, m and a stud s on lever m, a lost-motion device q being provided between levers c, m which are biassed by tensioned springs r, p respectively. On continued rotation the raised portion of cam b passes into a notch t in lever c and spring r which is stronger than p retracts levers c, m, releasing the alarm. The alarm may be arrested by depressing a knob 2 to rock a pawl w into a position against lever c thereby locking the reed, the pawl remaining in this position until rotation of the cam b depresses lever c still further and releases the pawl. If the knob 2 is not operated the alarm sounds until the cam 2 rotates and depresses the lever c into arresting position. The cam b is rigid with a shaft a, Fig. 3, normally driven through a friction clutch e by a gear wheel d loose thereon. The wheel d is rigid with a graduated dial g on which a pointer h fixed to shaft a indicates the alarm setting, the setting being altered by rotating a knob j. In another embodiment the members c, mare dispensed with, the cam b and pawl w acting on an extension of or attachment to the reed. In a further embodiment the cam b and pawl w, Fig. 7, actuate a lever 4 corresponding to the reed to close contacts 7, 8 to operate a vibrating alarm 12. According to the second Provisional Specification the cam spindle may be driven by clockwork mechanism other than electric, and the member corresponding to 4 in Fig. 7 may be substituted by a member controlling clockwork or other alarm sounding mechanism. Specification 15044/00, [Class 139], is referred to.

Title: Improvements in or relating to devices for wrapping wrapped connections
Inventor: SILINS ALEKSANDRS
IPC: H01R43/033
Filed: 1961-11-23
Abstract: 949,105. Wrapping electric terminals. GENERAL ELECTRIC CO. Ltd. Nov. 19, 1962 [Nov. 23, 1961], No. 41937/61. Heading B3E. A device for wrapping wrapped connections of the form in which wire is wound around two terminals in contact with one another comprises a spindle having at one end a hole which extends lengthwise of the spindle to receive the terminals to be wrapped, a path over which wire may be supplied to said end of the spindle adjacent said hole, whereby when the spindle is rotated the wire is wrapped around the terminals to form the wrapped connection, two adjacent portions of said path being in abutting, relatively rotatable members and said portions meeting at a point off-set from the axis of rotation of the members, means relatively to rotate said members when a wrapped connection is to be made so that the wire is cut at said point, the part of the wire cut off being of the required length for the wrapped connection, and means which operates to realign said portions of the path when the wrapped connection has been wrapped so that the wire can again be supplied to said end of the spindle. Wire 6 from a groove 44 in a spindle 42 is wrapped around a pair of contacting terminals received in a hole 43 in the spindle as the spindle is rotated through a clutch 28, 29, shaft 30 and block 45 by an electric motor. Initial rotation of the block 45 causes the wire to be cut at the junction of this block and a block 38, held non- rotatable by a tube 23, as a bore 48 in the block 45 rotates out of alignment with a bore 41 in the block 38. When the motor is stopped after wrapping and the clutch 28, 29 disengaged, a spring 34, surrounding the shaft 30 and secured at its front end to a fixed housing 31 and bearing at its rear end against the clutch plate 29, tends to unwind to rotate the shaft 30 in the reverse direction. This reverse rotation is stopped by a pawl 35 when the bores 41, 48 are aligned. Jaws 21 on a slide 16 then grip the wire 6, which passes from a reel 5 and over a pulley 11 and through a tube 22 on the slide, as the slide is pushed forwards by a handle 17. Wire 6 projecting through the tube 22, and tube 23 and bore 41 is thus pushed through the groove 44, the tube 22 telescoping in the tube 23. A spring 19 thus returns the slide 16, jaws 37 on the block 38 preventing the wire from being drawn back. Specification 890,730 is referred to.

Title: Method of maintaining the pressure in a liquid heating plant and plant for carrying out the method
Inventor: BREJNER G
IPC: F24D3/10
Filed: 1972-09-14
Abstract: 1398569 Pressurized liquid heating G BREJNER 14 Sept 1972 [17 Sept 1971] 42714/72 Heading F4A In a pressurized liquid heating system in which the pressure in a chamber 1, connected by pipe 2 to a heating plant, prevents the liquid from boiling at its operating temperature, a method of maintaining pressure comprises feeding the chamber with vapour generated in a separate evaporator 3 and using a supplemental supply of pressurized gas, e.g. nitrogen from container 7. A pressure sensitive element B operates regulator B1 to switch on a heating element 4 when the pressure in the chamber 2 falls below a predetermined minimum; the liquid in evaporator 3 boils and the vapour passes to raise the pressure in the container. If the vapour supply is insufficient to maintain the predetermined minimum pressure element A reacts to operate gas release valve A 1 . At increasing pressure the vapour content of the gas/air mixture in the container condenses, and when this effect can no longer compensate for the pressure increase pressure sensitive element C reacts to operate vent valve C1. In the tape of system which employs a boiler as the heating source with a gas supply connected to the boiler vapour space, the method may be carried out by connecting an evaporator 3 between the water and vapour spaces. Fig. 2 shows a boiler having an overhead drum, a liquid connection being provided between the evaporator and the bottom of the boiler at 8. To reduce the effect whereby liquid in the evaporator is carried into the chamber by the generated vapour a construction of the evaporator 3 is described (Figs. 3, 4, not shown) in which one or more open ended concentric tubes are arranged in the liquid space of the evaporator with heating elements being arranged within a central tube and between tubes.

Abstract: 1417475 Agglomerating hydrous sodium silicate STAUFFER CHEMICAL CO 13 Sept 1973 [12 Oct 1972] 43037/73 Heading C1A A material comprising at least 75% hydrous sodium silicate is agglomerated by vigorously agitating particulate hydrous sodium silicate (SiO 2  : Na 2 O wt. ratio 1À6 : 1 to 3À4 : 1) so that the particles are forced together, at 130- 230‹ F. and a loss-on-ignition at 1470‹ F. of 18- 30% for long enough to increase the size of substantially all the particles. Up to 12% water may be added during agglomeration. Mere agitation in pans or kilns is not sufficient, there must also be a compacting action by balls, rods or mixing screws. The material may be preheated before entering the agglomeration zone and may be partially dried after leaving it which further increases the bulk density. The product may be graded for size, fines being recycled and oversize ground and re-cycled. The starting material may be obtained from a sodium silicate solution by spray-drying or by drum-drying and grinding.
