Abstract: 537,681. Stapling continuous filaments. TENNANT, W. J. (Comptoir des Textiles Artificiels). Sept. 19, 1939, No. 26195. Drawings to Specification. [Class 120 (iii)] A sliver of staple fibres is formed from a bundle or lap of continuous filaments by feeding the bundle &c. obliquely between two co-operating sets of shearing discs disposed on parallel shafts, the bundles being given a movement transversely of the feeding movement which is at right-angles to the shafts. In an example the bundle is given a transverse reciprocating motion of 2-10 strokes per minute over a width of 1 mm. ; strippers may be provided to prevent accumulation of fibres between the knives.

Filed: 1927-10-07
Abstract: 280,175. Wilson Welder & Metals Co., Inc., (Assignees of Churchward, A.). Nov. 8, 1926, [Convention date]. Supplying consuming devices.-To ensure rapid recovery of no-load voltage when an arc-welding load is removed from a shunt wound or undercompounded generator a resistance in the shuntfield circuit is temporarily short-circuited. An electromagnetic switch with spring-closed contacts 14 tends to short-circuit a rheostat 7 in the shunt-field circuit. A coil 18 in the load circuit, or across a current-carrying device such as a choke 9, holds these contacts open whilst welding is in progress, and a coil 19 across the dynamo brushes holds them open when normal open circuit voltage is attained. The coil 19 may be in series with the field or in a parallel circuit including a resistance 21 whereby the switch, may be adjusted for a particular voltage. The field rheostat may be interlinked with this resistance for simultaneous adjustment.

Abstract: 958,541. Lubricating. GES. FUR LINDE'S EISMASCHINEN A.G. July 24, 1961 [July 22, 1960], No. 26735/61. Heading F2A. [Also in Division B1] In a means for lubricating a rotary compressor 1, oil is forced by compressed air from a sump 4 on which the compressor is mounted, is passed through an oil-cooler 21, a conduit 24, an oil-cleaner 25, a valve 26, through bearings 8, 9 of the compressor, which are cooled as well as lubricated, and into a chamber 16. Air entering the compressor at 13 also passes to the chamber 16 and is compressed by slidable vanes 7. The mixture of compressed air and oil is then passed to the sump 4 via a separator 17 and a filter 19. The oil-free compressed air is discharged through an outlet 18 and the separated oil is again passed through the cooler 21 which is mounted in a tubular jacket 20 positioned in the sump, so as to recommence the lubrication cycle. The compressor is coupled to, and is driven by, an electric motor, also mounted on the sump.

Title: Improvements in electrical impulsing circuits
IPC: H04Q1/32
Filed: 1945-10-13
Abstract: 602,388. Impulse correcting circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 13, 1945, No. 26843. Convention date, Nov. 23, 1944. [Class 40 (iv)] In an impulse correcting circuit the duration of the corrected impulse is determined by the time required for a condenser to be charged or discharged through a resistance until its potential is such as to cause the striking of a gas discharge tube. In the circuit shown, impulses incoming from wires 1, 2 are repeated by relay J to the vertical magnet V of a group selector switch under control of the correction circuit 10, 12, 13. On connection from the preceding switching stage dialling relay C operates immediately to earth on wire 3. Impulsing relay A operates to the incoming loop over wires 1, 2 followed by release relays B and D and by relay G. Relay D connects dial tone to line. Relay B earths wire 3 to hold C and the preceding switch. On impulsing, each release of A operates J which locks at J1, energizes the vertical magnet V and releases G which disconnects the operating circuit for J. On operation, J disconnects the charging circuit for condenser 12 which discharges for a predetermined time through resistance 13 until gas discharge tube 10 fires, whereupon its anode current through the lower winding of J neutralizes the effect of the holding current in the upper winding and J releases, re-operating G, de-energizing the vertical magnet V, restoring the charging circuit for condenser 12 and opening the anode circuit of 10 at J1. Vertical magnet springs V1 at each impulse complete a pre-energizing circuit for A to' assist re-operation when the impulsing loop recloses. On the first vertical step F operates to disconnect dial tone and transfer the circuit of the upper coil of relay C to the back contacts of A. Relay C is now held mainly by pulses over its lower winding by relay J, but partly also by the initial pulse over its upper winding from relay A so that the effective length of the impulse received by it is increased sufficiently to ensure that it does not release during impulsing. At the end of the impulse train C releases and completes a rotary stepping circuit and when an idle outlet is found, E operates over wiper 6 to stop the switch stepping and switching relay H operates in the usual manner, the remainder of the relays, except F, releasing. If all outlets are .busy, 11th step cam springs CS release relay D which opens the rotary stepping circuit and sends out busy tone. The selector releases in the usual manner, F releasing when the switch is normal.

Divided out of 601,133, [Group XIII]. , [Class 38 (iv)] [Also in Group XIII] A refrigerated display case has a lower opentopped display chamber communicating with an upper chamber, there being refrigerating coils in each chamber operated by a common machine M, a thermostat 30 in the upper chamber for starting the refrigerating machine after defrosting, and a thermostat 32 in the lower chamber for stopping the machine and defrosting the upper coil by a heater 28 when a predetermined low temperature has been reached in the lower chamber. The description is identical with that of Specification 601,133. When the temperature in the display chamber reaches a predetermined low value, feeler bulb 32 opens a thermostatic switch 31 de-energizing the solenoid 35 of a magnetic contactor 33 to open switches 37, 38, stopping the compressor motor M and closing a refrigerant valve 17 and the switch 36 of the heater 28. The switch 31 then closes, but the solenoid 35 is not energized until a feeler bulb 30 in contact with the upper coil reaches a predetermined high defrost temperature. Thermostatic switch 29 is then closed, energizing the solenoid to open the heater switch 36 and the valve 17 and close the switches 37, 38 to start the motor.
