Patent GB-705699-A (GB)
Title: Improvements in electric motor control system for spooling apparatus
Inventor: BRUESTLE CARL OTTO
IPC: B65H59/38
Filed: 1951-07-13
Abstract: 705,699. Winding. wire &c. SYNCRO MACHINE CO. July 13, 1951, No. 16671/51. Class 120(2) [Also in Group XXXVII] A spooling. machine comprises a reversible three-phase motor 10 driving a spool 15 through gearing 14 and. a magnetic slip clutch 11 which has an exciting winding 18 controlled by rheostat 19. Another motor 20 similarly drives a spool 25. When a wire-drawing or other processing machine which feeds material to the spooling machine is started, contact 30 is closed to energize both a timing, mechanism 70 and a starting relay 90 for the motor 10, the tension of the material being wound on spool 15 being regulated by adjustment of rheostat 19. Upon expiration of the period to which the timer 70 is set the motor 20 is started and the spool 25 is kept at a desired speed by means of a tachometer generator 26 which supplies a vibratory relay 150 having contacts 153 in the circuit of winding 28 of clutch 22, the clutch being alternately energized or de-energized according as to whether the speed of the spool 25 is too low or too high. The initial energization of relay 150 causes the completion of a circuit through reactance coil 38 and a relay 170 which controls a relay 80. the arrangement being such that the relay 80 will only be actuated when a rod- 37, coupled to the transverse mechanism of the spooling machine, moves into the coil 38. When relay 80 is actuated the coil 200 of an electro-pneumatic valve is energized and a piston is moved to transfer material from the full spool 15 to the empty spool 25. The relay 150 is now connected to the tachometer generator 16 and stops vibrating so that the energization of clutch coil 28 remains constant. The motor 10 is braked by application of reverse current and the timer 70 is re-set to zero. As the motor 10 approaches standstill a plugging switch 12 disconnects the motor, the timer 70 then being restarted for another similar cycle of operation during which the full amount of material is wound upon the spool driven by the motor 20 and is then transferred to that driven by the motor 10. When shutting down the spooling machine, the closure of contact 71 of the timer 70 causes the wire-drawing or other processing machine to be stopped, and then the contact 30 is opened to initiate reverse current braking. Specification 691,991 is referred to.

[Class 7 (ii)] An internal combustion engine comprises a stationary housing 10 bored to receive a partitioned sleeve 11 having both reciprocating and continuous rotary movement, the sleeve being provided with ports which cyclically register with intake, .ignition 'and exhaust ports in the housing, compression heads 17, 18 within the sleeve co-operating with the partition in the sleeve to form combustion chambers and the reciprocation of the sleeve being converted by cam means 14, 15 into rotary movement to operate the power take-off means. The cams 14, 15 define a track 16, Fig. 4, of simple harmonic form and are engaged by opposed followers 57 on a body 56 having inwardly-extending bearing members guided on cylindrical members 44 secured to a head 41 which carries the driving-gear 19 of the engine power-shaft 54. The members 44 are also secured to a head 46a and combustion head 18 which thus partakes of the rotary movement of head 41. The block 20 has longitudinal exhaust opening 22 and inlet opening 23 coacting with ports 29, 30, one on each side of the partition 26, which in conjunction with the rotary head 18 and a stationary head 17 provides two combustion spaces 27, 28. The head 17 is cooled by an oil spray 37 comprising orifices 39a opening against a conical baffle 39b. Each combustion chamber has a sparkplug cluster 60, 60a. In operation, considering the upper combustion chamber only, the port 30 first opens to inlet port 23, Fig. 5. The induction stroke follows and then the compression stroke. Before top centre, the port 30 opens to the plugs 60, ignition being timed to occur about 25 degrees before top centre. Towards the bottom of the power stroke the port 30 opens to exhaust passage 22, and remains open during the exhaust stroke. The combustion chamber 27 is associated with a similar four-stroke cycle. A number of power units similar to that-described may be arranged horizontally in line in an airplane wing, or they may be arranged vertically, or a radialtype engine may be arranged with pinions 19 engaging a ring gear.

Title: Punching presses
IPC: B21D55/00
Filed: 1975-04-23
Abstract: 1497938 Controlling shearing operations SMG SUDDEUTSCHE MASCHINENBAUGmbH 23 April 1975 [23 April 1974] 16831/75 Heading B3W In a fine punching press, a press table 5 is raised by a main piston 8, 10 and quick acting pistons 9. Resting on pistons 9 are sensing pistons 7 in cylinders 17 in the piston part 8. In operation fluid is supplied above the pistons 7 and the pistons 9 are then actuated, raising the piston 8, 10, table 5 and punch 4. In normal operation, a switch 6 is operated by the piston 8 before a switch 16 is operated by the closing of a gap 15. This sequence of switch operation causes a valve 12 to open to allow fluid to flow into the cylinder below piston part 10 which with pistons 9 carry out a punching stroke. Should a foreign body 3 be present in the tool space, increase in pressure above the pistons 7 causes the pistons 9 to move relative to the piston part 8 and thus close the gap 15 and operate switch 16 before the switch 6 is operated. This sequence of switch operation automatically stops the press, the piston 8, 10 being lowered and the gap 15 being restored.

Title: Improvements in electrical remote control or indicating systems
IPC: H04Q9/04
Filed: 1953-06-22
Abstract: 777,036. Selective signalling. BRITISH TRANSPORT COMMISSION and DELL, R. Aug. 3, 1954 [June 22, 1953], No. 17279/53. Class 40 (1). [Also in Group XL (b)] Signalling between, for example, the control office and the stations of a railway C.T.C. system is effected by a time-division system in which the distributers comprise one or more multi-electrode cold-cathode counter tubes. In the system described for indicating the condition of the station apparatus at the control office, each distributer has a tens counter and a units counter driven continuously from a common source and an impulse of abnormal amplitude is' sent in a particular position of the counter of each denomination at the office to synchronize the corresponding counter at the stations in each of its cycles of operation. Synchronous operation of counter tubes. Impulses from an A.C. generator at the office after amplification in VIA and V2 are fed to the operating circuit of a local units counter tube A and via line wire 2 or other communication channel to the operating circuit of units counter tube D at one or more stations. The pulse across the cathode resistor due to the ninth discharge is amplified by V1B and combined with the normal pulse from VIA to give a pulse in line 2 of abnormal amplitude. At the station(s), the discharge cannot pass from the eighth to the biased ninth cathode except in response to such an abnormal impulse. Consequently, if the counters at the office and the station get out of step they are re-synchronized on the ninth pulse in each cycle. The cathode pulse due to each tenth discharge in tube A after amplification by V3A and V4 operates a local tens tube B and, via a second line or other communication channel, the remote tens tube(s) E. The tens tubes are kept in synchronism in the same way as the units tubes. Signalling condition of station apparatus. Contacts 101 . . . 128 &c. indicate the condition of the station apparatus. They are associated with the units tube(s) in groups of eight (the ninth and tenth discharges being allocated to synchronization and transfer) and each group is associated with a discharge tube CT10, CT11, &c. These tubes are primed in turn by impulses from the tens tube(s). Consequently, each discharge of a units tube that corresponds to an operated contact 101 . . . 128 &c. causes a momentary discharge of a tube CT10 &c., and this in turn causes a momentary discharge of a tube COT to deliver an impulse over a further line or other communication channel 4 to the office. At the latter, discharge tubes CR101 . . . CR108 &c. equal in number to the number of indicating contacts at the station(s) and grouped in the same way receive impulses from the counter tubes so as to discharge in turn. These tubes apply priming impulses respectively to an equal number of tubes OP101 . . . OP108 &c. to enable them to respond to the amplified line impulses received from V5. These tubes energize relays 101 . . . 108 &c. to control indicator circuits.
