Abstract: 554,623. Automatic control systems for coiling machines. ENGLISH ELECTRIC CO., Ltd., CARNEGIE, H. S., ENGLISH, R. L., and TABB, R. P. E. Oct. 31, 1941, No. 14040. [Class 38 (iv)] Current; tension.-A D.C. dynamo-electric machine coupled to a reel for wire, strip &c., and controlled to maintain constant tension on the material has compensating means operating on the control device or devices in proportion to the angular acceleration or rate of change of angular velocity of the reel itself. These means may operate upon a vibratory or other regulator maintaining constant armature current upon a field winding of the dynamo electric machine or upon a booster to vary the E.M.F. applied to the armature. A flywheel machine is used to obtain a control factor proportional to rate of change, of speed. As shown in Fig. 1 the coiling machine 1 has its field current controlled by a vibratory regulator 3 responsive to armature current and an additional control is applied by a coil 3b carrying the current in the armature of a flywheel machine 8 having a .like excitation to the coiling machine and responsive to the difference between or the source of a constant E.M.F. 10 and the E.M.F. and a pilot exciter 6 driven by the reel. A booster 5, in series with the coiling machine and a generator 2 driven by the mill, may also be excited in part by this current In a modification the coil 3b is omitted and compensation control is applied through the booster 5, which is excited by a machine driven by the reel but itself excited by the current through the flywheel machine. The excitation of the flywheel machine in this case is constant. Specifications 554,624 and 554,625 are referred to.

Abstract: 290,669. Lebre, F May 20, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Compressor w i t h fluid chambers exposed to varying fluid pressures.-Fluid is compressed in stages by the expansion of another or the same kind of fluid in stages, each partial expansion causing a corresponding partial compression of fluid at a slightly different pressure, either by direct communication of the two bodies of fluid or by direct or indirect action on a piston or other separator. Fig. 3 shows a nest of rotary chambers 1 surrounding a distributor 7 formed with connecting passages and with inlet ports 9, 10 for the motor and compressor fluid. In the sector a-b, the chambers fluid is being compressed by inlet from the chambers in the sector c-d; the sector b-c constitutes the motor exhaust and the sector d-a the compressor delivery. If the walls separating the chambers are in the form of blades, their rotation will effect the inlet and delivery of the fluid. Figs. 4. 5 show a rotary set of chambers each having a free piston &c. Compressible fluid is drawn in through the inlet 13 and delivered through the outlet 11, while the motor fluid is supplied and withdrawn at the parts 9, 10. The piston rods 6 may be controlled by links or by the cam 14. In modifications, two nests of chambers may be employed rotating relatively without a distributor; the chambers may be fixed, with a rotating distributor; the cylinders may be disposed parallel in a ring around the distributor; the pistons may be replaced by blades.

Title: An entry or exit recording control apparatus
IPC: G07C9/00
Filed: 1967-03-30
Abstract: 1,117,728. Time - recording apparatus. TATEISI ELECTRONICS CO. 30 March, 1967 [6 April, 1966], No. 14568/67. Heading G4T. Apparatus for recording information such as the time and identification numbers of employees passing through a gateway is controlled by employee identification cards, each having an identification number recorded thereon and reason cards, each bearing coded information justifying unusual passage through the gateway, whereby on presentation of a reason card together with an employee identification card to the apparatus, means controlled by the reason card determine whether the employee identification number is recorded. Insertion of an identification card closes a switch to place a signal on line 100. A proximity switch 10 is operated if the identification card is genuine. Solenoid 18 is energized to close hold-on contact 19 and latch the identification card in position. Flip-flop 21 applies a signal on line 101 and actuator collation circuit 201. The identification number is fed along line 104 and compared with numbers stored in circuit 201. If genuine, a " valid " signal is applied to line 105 through INHIBIT element 24, flip-flop 25, and over line 102 to recording control circuit 203. This produces a signal on line 113 to pulse counter 204 controlling the recording of the identification number at 205 together with a time signal from clock 202. The final pulse from the counter 204 is applied to line 116 through OR element 34 to reset the circuit and release the identification card. The signal on line 102 also causes a lamp 7 to be illuminated and generates a pulse on line 107 to free the gate. Outside normal working hours, an inhibit pulse is applied to element 24 under the control of clock 202 to prevent recording of the identification number. If the identification number does not correspond to a number stored in circuit 201, an " invalid " signal is generated on line 106 to reset the circuit and release the identification card. If in addition to an identification card, a reason card is inserted in the apparatus, proximity switch 36 operates and a signal placed on line 117. AND gate 41 is opened by signals from the identification and reason card sensing means to energize solenoid 45 latching the reason card in position. If no information is to be recorded at this time, the reason card operates a detector to place a signal on line 118 and inhibit element 24. In addition, the signal passes through OR element 46 to energize means 52 withdrawing the reason card within the apparatus. If information is to be recorded, a signal is placed on line 119 to open AND gate 52 and operate recording control circuit 203. Information from the reason card is supplied over line 120 and recorded together with the identification number from the identification card.

IPC: H04L1/00
Filed: 1961-04-21
Abstract: 974,756. Pulse code modulation systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 24, 1962 [April 21, 1961], No. 14576/61. Heading H4L. In a pulse code modulation of data transmission system wherein one or more of the code elements in each code combination are used for a parity check, use is made of one or more additional code combinations which do not meet the parity requirements, these additional code combinations being detected by special equipment which carries out an operation in response to the additional code combination in use and also inhibits equipment which normally would operate on a parity failure. Parity bits, which contribute nothing to the information transmitted are inserted or not as necessary to make the total number of pulses in each character meet some arbitrarily chosen requirement. The system described uses all the possible pulse combinations complying with parity requirements for normal signalling purposes, and combinations not meeting parity requirements are used for START and STOP signals. Since the START signal cannot have parity check it is necessary for it to be repeated as a check before it becomes effective, but the STOP signal need not be repeated as it acts in the same way as a parity check failure and returns the apparatus to the standby condition.
