Title: Improvements in and relating to electromechanical transducers
IPC: H04R17/04
Filed: 1951-02-15
Abstract: 732,226. Gramophone pick-ups. COSMOCORD, Ltd., KELLY, S., and BROWNLEE, J. W. March 7, 1952 [Feb. 15, 1951], No. 3708/51. Class 40 (4). [Also in Group XXXVIII] A piezo-electric pick-up for lateral-cut records is provided with means to prevent strain on the crystal due to excessive vertical movement of the cantilever stylus arm. The crystal is supported in clips 18, 19, Fig. 2, which are pivotally mounted in members 23, 22 respectively. The stylus arm 14 is mounted in a tube 24 which is soldered to the clip 19. The tube 24 is extended to the level of the clip 18, so that if the arm 14 is raised excessively, the tube 24 engages the clip 18 and takes the strain. In a modification, Fig. 4, the clips 18, 19 have lugs 18a, 19a through which passes a shaft 30 pivotally mounted at its ends and fixed, e.g. by soldering, to the lug 19a. Thus the shaft 30 takes the strain due to excessive vertical movement of the arm 14. The desired torsional oscillation of the crystal is obtained (a) in the first construction by restraining the upper part of the crystal by means of clamping pads between the crystal and the walls of the body or the body can be filled with a viscous gel as described in Specification 732,225, and (b) in the second construction by soldering the clip 19 to the shaft 30. The transducer has a removable cover 11. Electrodes on the crystal surface are connected by flexible leads 26 to contacts 13.

Abstract: 640,317. Conveyers. BOBST ET FILS SOC. ANON., J. Feb. 9, 1948, No. 3774. Convention date, Feb. 10, 1947. [Class 78 (i)] A receiving accumulator for folded and stuck cardboard pieces comprises a lower endless conveyer belt having a receiving section and a section passing over a lower set of cylinders pivotally mounted near the delivery end, and an upper endless belt, pressed downwards by a set of cylinders with parallel axes and mounted in a frame pivoted about a vertically adjusted axis near the receiving end, some of the cylinders of the upper set are capable of independent vertical movement, and the pieces may be received by the accumulator from a direction either in alignment with or at angle to the line of travel. The lower belt 1 passes over a series of cylinders 3 in a frame 5 and pivots about a cylinder 4 mounted in a frame 6. The upper belt 12 presses on the belt 1 and passes under joined pairs of cylinders 9 and pivots about an end cylinder 10. The frame 5 is forced upwardly by a spring and bolt 7, 8. The upper frame 14 is urged upwardly by a spring 16 on a rod 15 interconnecting the two frames. The cylinders 9 are independently movable. Their axes are joined by members 17 having vertical racks 18 movable on toothed rods 19 interconnecting the frames 14. The rods 19 carry opposed springs 21, 22 connected to a central pinion 23 meshing with a pinion 24 rotated by a rod having a claw coupling 26 for limiting the drive of the pinion and prevent breakage of the springs and a locking coupling 27. Rotating the rod causes the cylinders to rise or fall. The cylinder 10 is adjustable vertically in the frame and the lower conveyer may be made horizontal for delivery at an angle to it.

Title: Improvements in or relating to gauges for internal measurements
IPC: G01B5/08
Filed: 1943-03-16
Abstract: 565,504. Gauges. KAPELLA, Ltd., and COOKE, E. A. March 16, 1943, No. 4269. [Class 106 (ii)] A gauge for measuring internal diameters of gun barrels or other tubes comprises a body A carrying two relatively movable gauging elements F, F<4>, the relative movement of which controls an indicating or recording instrument, and two pairs of ligament springs A<1>, A<2> and A3, A<4> (not shown) by which the body A is supported from a guide member C<1> slidable along the tube to be gauged. The guide member, which may constitute the tool for boring the gun barrel, carries an adapter C to which are connected the springs A<3>, A<4> supporting an annulus B bearing the springs A<1>, A<2> connected to the body A, which is accordingly free to move with its axis parallel to itself. Mounted on ball bearings in the body is a hollow member D bearing three adjustable reaction points F<4> and F<6>, F<7> (not shown) and the feeler F which is spring-pressed inwards against a spring-pressed lever H<1>, pivoted at H<2>. The feeler F is adjusted initially by a wedge H controlled by a worm H<7>. Movement of the feeler and hence of the lever H<1> affects the reluctance of coils H<4>, leads from which pass through a tube C' to a meter and a potentiometer, Fig. 6 (not shown) affording a measure of the movement. The hollow member D is rotated through a small angle for successive measurements. The weight of the gauge body A is compensated by an adjustable spring A<5>. A follower member G<1> is normally locked up clear of the tube, but in gauging the bore of a rifled barrel, an end cap G is released and turned until the follower G<1> lies'on the base of one of the grooves and the feeler F lies on one of the crests. The end cap and follower are then locked in position, and the gauge is passed through the bore once for each groove. In the modification shown in Fig. 8, movement of the feeler S rocks a block R, pivotally secured to the frame by springs R3 at right angles, and the block displaces an armature axially to affect the reluctance of coils Q. In this case, the guide member C' embraces the gauge body. The reaction point S<1> may be adjusted through a block similar to R, Fig. 13 (not shown), and instead of the other two reaction points, a steadying plate V, Fig. 14, with suitably shaped ends V<1> may be employed.

The ester is used in quantities of 0.2 to 5.0 and preferably 0.5 to 2.0% v./v. of the medium.  The ester is an animal or vegetable oil such as palm, arachis, sunflower seed, lard, castor or rape seed oils.  It may be an ester of a monohydric alcohol such as methanol and ethanol or a polyhydric alcohol such as glycerol, wherein one or more hydroxyl groups are esterified, with one of the above fatty acids and particularly palmitic, stearic, oleic, linoleic, ricinoleic or erucic acid, e.g. methyl oleate, ethyl oleate, glycerol ricinoleate and glycerol trioleate.  The medium may contain a source of (a) organic nitrogen, e.g. fish meal, meat meal, meat extract, casein, dried autolysed yeast, malt extract, urea, soya bean meal, corn meal and corn steep liquor, and (b) carbon, e.g. sucrose and/or lactose and ammonium acetate.

Abstract: 548,308. Looms with stationary weft supply. SULZER FRERES SOC. ANON. April 3, 1941 No. 4461. Convention date, April 6, 1940. [Class 142 (ii)] In a loom having a stationary weft supply at one or both sides of the shed, the weft needles move simultaneously in opposite directions, and one at least of the needles moves beyond the middle of the shed. The needles are so operated that the needle introducing the weft into the shed enters the shed later than the needle receiving the introduced weft. Each needle, 10, 11 has two gripper members 12, 13, 14, 15 having nippers 17, 18 and spreading devices 21, 22 fixed on the slay serve to open the nipper towards the middle of the shed. In this form the weft to be transferred is disposed in a direction parallel to the direction of movement of the needles. In a modification, Fig. 5, a laterally bent hook member 35 mounted upon the transferring needle 33 holds the weft at right angles to the movement of the needles so that one pair of nippers does not have to pass through the other pair of nippers. A lateral projection 36 ensures that the weft is firmly held by each pair of nippers 33a, 34a. A hook 37 on the needle 34 serves to guide a weft introduced by the needle 34 from its side of the shed.
