Title: Improvements relating to air or gas compressor apparatus or plant
IPC: F04B49/06
Filed: 1937-11-17
Abstract: 511,679. Gas compressors. WORTHING- TON-SIMPSON, Ltd., (Worthington Pump & Machinery Corporation). Nov. 17, 1937, No. 31673. [Class 8 (i)] [Also in Group XXXV] Gear for operating the control or unloading valves of air or gas compressor plant and actuated by fluid pressure under control of a device responsive to pressure conditions in the compressor is constructed so that a time delay interval is ensured between the successive operations of the valves. The control or unloading valves 3-8 of the compressor are connected up in pairs to solenoid-operated distribution valves 12, 15, 17, the solenoids of which are actuated through switch mechanism including the stationary contacts 27, associated with movable contacts 28, carried by blades 31, Fig. 2, which are operated by cams 33 on a main shaft 34. The master switch which inter alia controls the motor 37 driving the cam shaft 34, includes a contact 52 located between further contacts 48<1>, 491 and controlled by a diaphragm which is exposed to the pressure prevailing in the compressor. With appropriate rise or fall of the fluid pressure contact 50 engages either contact 48<1>, 49<1> to close the circuit including the motor 37, thus causing a rotation of the shaft 34 and opening of the appropriate switch with the resultant de-energisation of the solenoid 18 connected in circuit with the switch thus operated. The re-positioning of the contacts 48<1>, 49<1> to effect a further unloading or loading is accomplished through a cam 76 mounted on a shaft 74 which rotates at the same speed or same proportional speed as the shaft 34. The cams 33 ensure a time delay interval between successive operations of the unloading valves. A second motor 85, acting on the shaft 74 through differential gear 66 and controlled from a cam 81 operates in an overriding fashion to return the contacts to their normal position. A modification is described in which pressure responsive devices are employed to operate the electric circuits controlling the solenoids. In this form the required time interval in the operation of the pressure responsive means is ensured by providing a restriction between a pair of receivers.

Patent GB-482055-A (GB)
Title: Improvements in straight-bar knitting machines
IPC: D04B11/00
Filed: 1936-11-21
Abstract: 482,055. Knitting. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. Nov. 21, 1936, No. 31896. [Class 74 (ii)] Automatic means for adjusting the pattern chain of a straight-bar machine in step with the other moving part comprise a spring actuated bolt A, which when projected puts the chain-advancing mechanism out of action and a latch lever G, controlled by pilot studs H<1> on the chain H to hold the bolt withdrawn; an arm J connected to the draw-bar may also hold the bolt out of action. The bolt A, when slid to the right in its bearing B intercepts one arm of a cam lever D. The lever D, when free of the bolt A, is moved by a cam M<1> and by means of a lever E and pawl E<1> feeds the pattern chain H forward. The studs H<1> are mounted in advance of those studs which control the adjustments necessary to produce full fashioned garments automatically. Just before the machine starts to fashion, a stud H<1> arrives under the latch lever G and lifts it out of engagement with a collar A<3> on the bolt A, which is thus free to slide under the influence of a spring, unless otherwise held back. If the draw-bar is at the far end of its traverse the bolt will be held back bv an arm J attached to the bolt and connected by a cable or link to the draw-bar. The amount of slack or lost motion in the connections is such that the draw-bar moves the arm J, only at the end of its traverse. In this case the bolt is drawn back or held back by the engagement of a roller A<2> with a cam J<1> on the bearing B. Should the pattern chain be out of step with the other moving parts, the draw-bar will not be at the end of its traverse when the stud H arrives under the lever G. In this case the bolt A is tripped and the advance of the chain is held up until the draw-bar reaches the end of its traverse. The cam lever D is then released by the bolt A and the pattern chain, which has thus been brought into step, is advanced to start the fashioning.

A U-tube device, for use in apparatus for measuring changes in volume of soil samples with respect to time under a constant water pressure, comprises a U-tube formed by two bores 2, 3 and a connecting cross-passage 5 in a block of transparent material e.g. "Perspex" (Registered Trade Mark), which has in it, at its end remote from the cross-passage 5 a by-pass passage 15 provided with a closure valve 16. The device has two inlet unions 7, 8, the union 8 being connected to a tube 9A leading to the soil sample: Passages 7, 13 leadine from the union 7 communicate wjth the bore 2, and passages 14,10 lead from the bore 3. An air vent passage 11 closed by a valve 12 is also provided. The lower part of the U-tube contains a liquid immiscible with water e.g. a fluorocarbon, and the rest of the device is filled with water. The valve 16 has two reduced portions 17, 18 separated and sealed by rubber O-rings 19, 20, 21, in the bypass passage 15. With'the valve 16 in the position shown, the passages 13, 14 communicate with the bores 2, 3 respectively and as the soil sample decreases in volume, the water-immiscible liquid interface rises up the bore 3, the movement being measured by graduations on the outside of the transparent block. When the interface reaches the top of the bore 3, the valve 16 is moved to the left in the drawing so that the passages 13, 14 and the top ends of the bores 2, 3 all communicate via the reduced portion 17, and the interface level in the bore 3 falls until it is level with that in the bore 2. By returning the valve 16 to the position shown a further set of readings of the change in volume of the soil sample may be obtained. The device may be used as an inverted U-tube,if desired.
