Title: Improvements in or relating to injection syringes and an injection needle for use therewith
IPC: A61M5/34
Filed: 1954-01-16
Abstract: 739,753. Hypodermic syringes. VOORHORST, J. Jan. 16, 1954, No. 1361/54. Class 81 (2). An orifice is formed in a needle mount which may be opened by relative turning of the mount and syringe nipple on which it is placed, so as to vent the bore of the nipple to atmosphere. Such venting ensures that there shall be no sucking back of the contents of a used needle as this is withdrawn from the syringe. In its simplest form a drilling 4 communicates with the bore 3 of the nipple 1. The needle mount is provided with a longitudinal slot 7, communicating with its axial bore, so that, by rotation, this slot may be aligned with the hole 4 before the needle is removed. The hole 4 and the slot 7 may be replaced by axial surface grooves if desired. In a modification the mount is screwed on to the syringe nipple and has a lateral drilling leading to an internal cavity. When the mount is screwed tightly on to the nipple the end of the latter is pressed tightly against the further end of the cavity and is sealed except for its communication with the needle. Immediately the mount is unscrewed this seal is broken and the nipple is vented to atmosphere through the cavity and lateral aperture.

Title: Improvements in feeding mechanism for biscuit & other ovens
IPC: A21B5/02
Filed: 1923-01-19
Abstract: 219,344. Vicars, T., and Vicars, E. L. Jan. 19, 1923. Biscuits.- In a plant for making and baking biscuits comprising a feeding or panning conveyer placed between the cutting-apparatus and the oven, a variable speed gear is interposed between the cutting-mechanism and the drive for the oven conveyer and means are provided for independently varying the speed of the feeding-conveyer. The invention is described in relation to a conveyer oven having vertical baking and cooling chambers. The main driven shaft 1 is connected by gearing to the cutter shaft 5, and bv a chain and sprockets 6, shafts 8, 9. suitable bevel gearing, a crank disc 27, connecting-rod 92, pawl and ratchet mechanism 30, 31, 32 to a shaft 33 carrying the sprockets 34 of the feeding-conveyer 35. The conveyer 35 carries the trays 36 from the cutter to a point adjacent to the baking-tower 37 into which they are shot by a known skip mechanism. A number of pawls engage ratchet wheels 31. 32, on the shaft 33, and are carried by a bridge 30 on the connecting.rod 29, and the intermittent motion is varied by adjusting the crank pin 28 in a radial slot in the disc 27. The box 10 encloses a variable gear for, and common to, the oven chains, cooling-chamber chains, the top transfer mechanism and discharge conveyer 26, an operating handle 14 being provided. The discharge conveyer 26 is driven by the, variable speed shaft 13, gearing 15, 16, bevel gearing 19, 20, shafts 17, 18, sprocket chain 22, and a shaft 23 having a disc 90 thereon carrying pins 24 which engage the spaces in a Maltese-cross wheel 25 on the conveyer shaft 80, the pins 24 being followed by a stop portion 91 which prevents the conveyer 26 from moving during the motion of the cooling-chamber chains. The vertical shaft 18 extends upwardly and is connected by bevel gearing to a crank disc which actuates a ratchet arm and moves the baking and cooling chains intermittently. A conveyer operated by another Maltese-cross device transfers the trays from the baking-chamber to the cooling-chamber.

Title: Improved means for controlling the phase displacement between driving and driven members in systems for transmitting angular motion
Filed: 1944-01-29
Abstract: 582,144. Toothed gearing; cams. HOMERSHAM, B. R. M. Jan. 29, 1944, No. 1717. [Classes 80 (i) and 80 (iii)] [Also in Group XX] A phase-adjustable rotary motion transmission, for introducing a deviation-correction in a compass repeater, or for calculating-machines or predictors, comprises a differential gear 34 (not described), the sun-wheels 3a, 4a of which are geared respectively to an input shaft 1a and an output shaft 6, whilst its planet carrier 34 is subjected to a further motion controlled in phase, sign and magnitude by an adjustable cam 17, driven through gearing 16 by the input shaft 1a, and serving to oscillate a bellcrank 19, pinned at 24 to a rotatable disc 25, which drives the planet-carrier 34 through worm gearing 31, Fig. 2. The cam 17 comprises a series of rods 17 axially adjustable on a detachable supporting drum 14, in grooves if desired, and clamped by external bands 18 to expose an overhanging cam end-face tracked by a spring-loaded roller 22 on the bellcrank 19, or the roller may engage grooves in the rods so that the roller-loading spring may be dispensed with. As applied to compass deviation-correction, the input shaft 1a is driven by a motor 1, which rotates at a higher speed than the compass transmitter motor (not shown), whilst the cam 17 is geared down to rotate at the same speed as the compass transmitter, so that deviation corrections, in degrees can be indicated directly as axial ordinates on a circumferential scale on the cam drum 14 and the idle ends of the cam rods 17 can be adjusted directly on the scale. Correction for magnetic variation can also be made by angular adjustment of the disc 25, which carries the pin 24 of the bellcrank 19, this adjustment being effected by turning a pinion 36, meshing teeth on the disc 25 which is afterwards clamped by screws 30 in its supporting disc 26 which carries a scale 29. The output shaft 6 drives cams 8 operating contacts 12 of an electrical impulse transmitting system leading to the compass repeater, which thus gives corrected readings.

Abstract: 798,885. Separating solid materials. MCINTYRE, R. C. Nov. 9, 1956 [Jan. 18, 1956; Oct. 2, 1956], Nos. 1772/56 and 30037/56. Class 117 A pneumatic separator includes frustoconical casings 1, 2 defining between them an annular space 3 for the upward flow of an air current which carries away the lighter particles of a material flung from a centrifugal disc 6, the heavier material falling into a hopper 10. Means are provided to vary the speeds of the air current and disc, and the rate of material fed to the disc from a shoot 7. Air is drawn through the apparatus by a suction unit 5a, Fig. 3, and via a cyclone separator 5b, and the air current may be adjusted by the unit or. by moving the outer casing axially relative to the inner one thereby varying the width of the space 3. Fig. 3 shows pins 1a on the outer casing adjustably engaging slotted pillars 2a extending from the base of the inner casing. In the embodiment of Fig. 4, louvres 11 are provided around the periphery of the inner casing for the overflow of air to assist the separation, said outflow being adjustable if desired by a rotatable louvred sleeve. Fig. 5 shows an alternative arrangement in which surfaces 13 and 14 extend from the inner casing and disc, and provide a diverging outlet for an air current, the outlet being adjustable by relative movement between the disc and inner casing. The air may be heated before and during its passage through the apparatus, and its linear speed may be kept substantially constant over a vertical distance below and up to the disc level. For the latter purpose the space 3 is arranged to have a substantially constant cross-sectional area over that distance i.e. the inner and outer casings may have different apex angles or a skirt 2a, Fig. 6a may be provided. The disc may include a conical member with flutes, vanes &c. centrally positioned thereon. In Fig. 7 the material is fed through a duct 7a which has a conical member 7b providing, in effect, a continuation or the inner casing.

Title: Hand grenade
IPC: F42C14/02
Filed: 1973-01-12
Abstract: 1413253 Hand grenade fuzes C A LECANDA 12 Jan 1973 1810/73 Heading F3A A hand grenade fuze which can be set for impact and/or delayed detonation comprises a striker 8 held at a safe distance from a percussion cap 19 by a safety pin 15; a spring-driven slide 30 carrying a detonator 37, a percussion cap 40 and a long delay 35; a viscously damped plunger 27 holding the slide at a safe distance from a striker 36; a further safety pin (not shown) holding the plunger 27 in its safety position; and a handle 1 holding both safety pins in their operative positions. A withdrawable safety means (not shown) holds the handle in position. When the grenade is launched, a mass 13 sets back and pushes the striker 8 tightly against the pin 15. However, when the acceleration phase is over, the mass is returned to its original position by a spring 10 and the pin 15 is withdrawn by centrifugal force to free the striker for action on impact. Meanwhile, the safety pin securing the plunger 27 is withdrawn by spring means and so facilitates delayed withdrawal of the plunger 27 from the slide 30. The percussion cap 40 is thereby ignited by the striker 36; and the detonator 37 is ignited by the delay 35 if the striker 8 has not previously been actuated. To set the fuze for delay action only, a plug 5 is turned so that the striker 8 is urged tightly against the pin 15 and prevents its subsequent withdrawal.

Title: Improvements in work holders of the centreless type for grinding machines
IPC: B24B41/06
Filed: 1956-01-20
Abstract: 823,384. Grinding. ULVSUNDA VERKSTADER A. B. Jan. 20, 1956 [April 7, 1955], No. 1938/56. Class 60. A workpiece 16, Fig. 1, is radially supported in relation to the rotary workholder 12 of a grinding machine by means of fixed supports, while bearing against an end surface 14 of the holder and is caused to be rotated by frictional drag produced on such end face by the action of fluid pressure introduced into a chamber 68 defined by rotatable and stationary walls 52, 56 having radiallyextending clearances provided between such walls to prevent contact between them. Surrounding the workholder are three brackets, 20, each of which is formed with a cylindrical chamber 22 provided with flexible diaphragms 28, 30 for supporting centrally within the chamber a bolt 34. An annular plate 5b provided with three lugs 58 for mounting it between nuts 60, 62 on the three bolts is arranged to co-operate, so as to form the chamber 68, with a second annular plate 52 which can rotate relatively to the plate 56 and has a centering cone 54 for contacting the workpiece 12. By admitting fluid under pressure, e.g. compressed air, to the chambers 22 through inlets 24, the bolts 34 are moved axially away from the workholder and carry with them the plates 56 to permit the insertion of a workpiece ; stops 70 on the plate 56 ensure that the plate 52 will move with the plate 56 during this operation. After insertion of a new workpiece, fluid supply to the chambers 22 is cut off so that springs 50 retract the plates towards the workpiece. The admission of pressure fluid to the chamber 68 through an inlet 66 then causes the plate 52 to urge the workpiece against the workholder with an axial force which is chosen to cause sufficient frictional drag between the workpiece and surface 14 to rotate the former and yet provide a clearance gap between the plates 52, 56 on both sides of the chamber 68, preventing contact between them ; the cone 54 ensures that the plate 52 assumes its correct radial position relatively to the workpiece. In the modification shown in Fig. 2, the bolts 72 are fixedly mounted in the brackets 20 and provide support for an annular plate 74 which carries by means of two diaphragms 76, 82 a second annular plate 56 so as to provide a chamber 78 between the two plates. A chamber 68 with clearance spaces is provided between the plate 56 and the relatively-rotatable plate 52. During grinding, fluid under pressure is supplied to both chambers 68, 78 so that the plate 52 urges the workpiece into driving relation with the workholder ; a lip 88 associated with the plate 74 defines the smallest clearance between the plates 52, 56. The workpiece may be released by interrupting the supply of fluid to at least the chamber 78. If desired, the clearance gap may be maintained at a predetermined width by suitably setting the pressure in the chamber, and it may be formed of labyrinth type.
