Title: Loading Apparatus
IPC: B24B41/00
Filed: 1967-08-01
Abstract: 1,190,225. Grinding; work transferring. HEALD MACHINE CO. 1 Aug., 1967 [8 Aug., 1966], No. 35220/67. Headings B3B and B3D. A loading apparatus comprises: (i) a shaft slidably and rotatably carried in a base, (ii) an arm extending laterally from one end of the shaft and having a workpieceholding means located a substantial distance from the shaft, (iii) a first actuator for rotating the shaft, (iv) a second actuator for sliding the shaft, (v) means causing the actuators to move the shaft and the workpiece-holding means in a cycle to successive positions relative to the base, and (vi) stop means assuring that the workpieceholding means has reached one of the said positions before the workpiece-holding means starts to move to the next successive position in the cycle, the stop means further assuring that the rotative movement of the shaft does not extend beyond a predetermined range and consisting of a cam follower extending from the shaft and a cam plate associated with the base and having guide surfaces to be contacted by the cam follower, the cam plate being a curved plate arranged concentrically of the shaft, the cam follower comprising a roller arranged with its axis perpendicular to the shaft axis, and the guide surfaces comprising edges of the cam plate. A shaft 12 slidable and rotatable in a base 11 has a laterally extending arm 13 provided with a loading plug 14. An hydraulic piston 15 rotates the shaft and an hydraulic piston 16 slides the shaft. Rotation of the shaft when the apparatus is inoperative is prevented by a piston 18 biased by a spring 19 to carry a pin 21 into engagement with the side of an arm 22 extending radially from the shaft. To limit movement of the shaft the arm 22 carries a roller 23 engaging a cam plate 24 having guide surfaces defining shoulders 25, 26, axial slots 27, 28 and a surface 29. A plate 31 on the tail end of the shaft co-operates with a switch 32 whose condition is indicative of whether the shaft is at the inner or outer end of its axial movement; the plate also co-operates with a switch 33 which indicates the position of rotation of the shaft when it is at the inner end of its axial movement. The apparatus may be used in an internal grinder. Cycle.-With the shaft 12 in " IN " position and the arm 13 in " UP " position, the plug 14 lies in a workpiece in a loading shoot. The plug is then moved to " OUT " " UP " position, and then to " OUT " " DOWN " position. The machine chuck is opened and a finished workpiece ejected. The plug is then moved to " IN " " DOWN " position, inserting the workpiece in the chuck; the plug is contracted to release the workpiece and the chuck is closed. The plug is moved to " OUT " " DOWN " position, and then to " OUT " " UP " position where it is parked between cycles.

Title: Differential pressure transmitter
Inventor: LUND JAN FREDRIK
IPC: G01L11/00
Filed: 1961-09-29
Abstract: 962,742. Pressure difference indicators. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Jan. 14, 1961], No. 35243/61. Heading G1N. A differential pressure transducer contains an electrically conductive fluid sealed between elastic members to which the differential pressure is applied, the resulting deflection of the elastic members beingused to control an electric current which is passed through the fluid perpendicularly to a magnetic field to create an opposing pressure differential whereby the current is a measure of the applied differential pressure, the fluid and the elastic members being wholly within the same housing. Mercury 4 is contained between diaphragm 2 and bellows 6, the remainder of casing 1 being filled with a non-conductive fluid 5, e.g. silicone oil, and closed by a second diaphragm 3. Bellows 6 supports an armature 7 close to a coil 8 in series with an A.C. source supplying a D.C. amplifier 20 through rectifier 18. Movements of bellows 6 cause the current to amplifier 21 to change. The output from amplifier 21 is applied through electrodes 10 to mercury 4, perpendicular to a magnetic field 9, thus causing an electromagnetic pumping action which produces a pressure in opposition to the applied pressure differential. The amplifier is adjusted to give zero output at zero pressure differential. In a modification bellows 6 is replaced by a third diaphragm which carries a carbon contact close to fixed carbon contact. These contacts are connected in series with contacts 10, a D.C. source and a meter, the current in the circuit depending upon the pressure between the carbon contacts. In a third embodiment (Fig. 3) the whole of casing 1 is filled with mercury 4, 4<1>. One diaphragm 3 carries an insulating member 8 which can seat on the tip of a nozzle 7 thus insulating region 4<1> from region 4. The electromagnetic pumping action tends to close the nozzle in this way, cutting off the current and allowing the diaphragm to return to its original position again. A train of square waves therefore flows in ammeter 15, the mean value representing the pressure differential. Alternatively pulse height and width controlling circuits may be provided and the frequency may be measured. If the carbon contacts in the second embodiment are replaced by metal contacts the device will produce a square wave output. If the output current is used to produce the magnetic field 9 the current will be proportional to the square root of the pressure differential, and if such an arrangement is used with flow restriction means in a pipeline the current will be proportional to the liquid flow in the pipeline. The total flow over a period may be determined by counting the pulses produced in the device shown in Fig. 3.

Title: Improvements in apparatus for untwisting material in twisted rope form
Inventor: MOORHOUSE WILLIAM JOSEPH
IPC: D06C3/00
Filed: 1954-12-08
Abstract: 794,429. Finishing fabric. BRADFORD DYERS' ASSOCIATION, Ltd. Dec. 8, 1955 [Dec. 8, 1954], No. 35595/54. Class 42 (1). [Also in Group XXXV] In apparatus for taking the twist out of cloth or other material in twisted rope form in which a twist detector, e.g. of the type comprising pairs of spring-loaded rollers, electrically controls a reversible twist remover, e.g. a turntable, and the untwisted but still gathered material is opened out to pass at full width between a pair of cloth guiders, there is located between the twist detector and the cloth guiders a width detector involving mechanically - operated switches or photo-electric devices which only renders the twist detector effective to control the twist remover when the width of the material is less than normal, indicating the existence of twist. In the width detector described, Figs. 1 and 2, the material (not shown) passes between tubular members 1 and U-shaped members 12 which are pivoted at 8 and normally maintain switches 6 open by virtue of pressure of the material. If, however, due to twist of the material, decrease in width allows one or other of switches 6 to close, the twist detector (not shown) is rendered operative. The distance between members 12 is adjustable by releasing clamps 11, satisfactory switch operation being maintained by corresponding adjustment of the position of switch operating stud 20 in two directions by lock-nuts 21 and collars 18 respectively. The location of the width detector relative to the twist detected may be adjustable to suit different widths of material and there may be coupling between this adjustment and adjustment of the cloth guiders.
