Abstract: 699,163. Extruding. SIEMENS-SCHUCKERTWERKE AKT.-GES. Dec. 7, 1951. [Dec. 8, 1950], No. 28775/51. Class 83 (iv). In a method of extruding from solid billets in a press in which the receiver is exhausted of air, the open end of the receiver is sealed in an air-tight manner by a metal disc after the introduction of the billet and the disc and billet are pressed by the ram after the air has been exhausted. In a press for extruding an aluminium or aluminium alloy cable sheath the receiver 11, Fig. 2, for a heated billet 12 has a flared end 15 in which a frusto-conical disc 18 of the same material as the billet is seated. An annular recess 16 connected to an exhaustion duct 17 permits removal of air from the receiver before the ram 19 descends and the disc is finally forced past the recess to completely seal the receiver during extrusion and may be finally extruded as part of the cable sheath. The lower end of the receiver is sealed by residue metal 13 remaining from the preceding pressing operation. The solid metal disc 15 may be replaced by a thin sheet metal disc with an upwardly flanged edge, molten metal being poured on to the receiver and the ram being lowered before the metal solidifies. In a modification adapted for use in a receiver having no exhaustion duct, a suction head 20, Fig. 5, having a seating 21 for the disc 15 and an annular recess 22 and exhaust duct 23 is attached to the open end of the receiver using a heat-resistant annular seal 24 of asbestos or aluminium. The head 20 may be readily. detachable as by a flange 25 which is inserted into a retaining pocket 26 secured on the receiver by a quick-release means, the head 20 being shifted by mechanical or hydraulic means.

Title: Process for automatic and rapid manufacture of crystallised or preserved fruit
IPC: A23B7/08
Filed: 1922-10-23
Abstract: 199,661. Fraisse FrÞres, and Navarre et Fils, P. July 6, 1922, [Convention date]. Coating confectioners' goods.-In a process for crystallizing fruit, the fruit is first bleached by immersing for several hours in boiling water containing a chemical, such as suphurous anhydride or tartaric acid, and is then immersed in syrup which is maintained at a constant temperature, the bursting of the fruit by the internal vapour pressure being avoided by maintaining a super-atmospheric pressure. The fruit is enclosed in a vessel a, which protects it from the air and light, and syrup contained in a tank c flows through the pipe d, percolates through the fruit and maintains the pressure in the vessel a. The syrup passes through a pipe e to a tank f to which sugar and glucose are added to counteract evaporation losses. The syrup is then sucked by a concentrating and re-heating apparatus g and delivered by a pump h and pipe i to the tank c. A vent j is opened during the introduction of the syrup to permit the escape of air. The constant temperature employed promotes osmosis and varies with different fruit. A temperature of 60‹ C. is mentioned. The vessel a may be enclosed in a water-bath chamber b, heated by a coil b<1>, bubbling-through device, or naked fire. A hotair stove may be used for heating or the vessel a may be logged or heated internally.

Title: Improvements in propeller pencils
IPC: B43K21/08
Filed: 1933-10-18
Abstract: 417,896. Pencil holders. BINA & BARREY, Ltd., BINA, F. C., and BARREY, F. F., 231, Liverpool Road, Islington, London. Oct. 18, 1933, No. 28822. [Class 146 (iii).] A propeller poncil is provided with a screw action comprising a screw-threaded tubular element and a relatively rotatable spiral spring. A tube a is provided with an embossed thread a<3> and with split portions a<1> at one end which are bent over so as to rotatably engage with an annular groove d<1> in a gland d which forms a screwed connection between the barrel band point portion p of the pencil. A sleeve s may surround the portions a<1> if they are flexible, and the upper end of the gland d may be rounded so as to permit easy engagement with the portions a'. A lead carrier e<2> is formed on the lower end of a tube e which is of non-circular cross-section so that it will slide but not rotate in the central aperture of the gland d. A spiral spring a<4> engaging with the thread a<3> is mounted on the tube e, with an inturned lower end passing through a hole in the tube and an inturned upper end passing through a longitudinal slot in the tube and then extending downwards through the tube to form a pusher-rod for the lead b. At the lower end of its travel the spring passes into an enlarged part a<3> of the tube a, when the further advance of the upper part of the spring and pusher rod expels the lead; the compression in the spring is sufficient to return it to the thread when the direction of rotation is reversed. An enlarged portion a<3> at the rear end of the tube a prevents overwinding in a similar manner at that end of the travel. The upper end of the tube a forms a lead reservoir, which is closed by a friction-tight head c which acts also as an operating knob.

Title: Apparatus for positively controlling a plurality of devices
IPC: B63H21/22
Filed: 1974-07-01
Abstract: 1450856 Change-speed control; Bowden mechanisms; linkwork STEUERUNGSTECHNIK mbH & CO GES FUR 1 July 1974 [3 July 1973] 29017/74 Headings F2D and F2K A single actuator imparts differing movements to a plurality of linearly guided output members through transmission means comprising a plurality of endless loops, e.g. chains, belts, ropes, each of which carries an entraining member engaged with gating means, e.g. a slot, on a respective output member, and each of which is associated with a respective rotary member on a shaft operated by the actuator and with respective guiding means. An embodiment has a shaft 2 with actuator lever 3 and key 11 by which it is coupled to a pair of chain wheels 9, 10. If the shaft is displaced axially in the direction of the arrow A, only the wheel 9 is rotated by the shaft. Endless chains 14, 15 pass round the respective wheels 9, 10 and around various guide wheels 16, and entraining members in the form of blocks 14a, 15a fixed to each chain are slidable in slots 12f, 13f of respective carriages 12, 13 which are guided by rollers 12a ... 12d and 13a ... 13d for rectilinear movement in a housing. Due to the arrangement of the guide wheels 16, rotation of the shaft 2 in either direction from the position shown will firstly cause the block 14a to move the carriage 12 to the right, whilst the carriage 13 remains stationary as the block 15a moves along the slot 13f, and further rotation of the shaft 2 will cause the block 15a to move the carriage 13 in either direction, depending upon the direction of rotation of the shaft. The carriages 12, 13 may be connected to the inner members of flexible push-pull cables connected respectively to the throttle of an engine driving a concrete-mixer drum and to coupling means for controlling rotation of the drum for mixing or emptying. Other arrangements of guide wheels 16 are described giving different relationships between the movements of the carriages 12, 13 to suit combined control of engine throttle and reversing gearing for a boat, and combined control of reversing gearing and drive means of vibratory mechanism in a soil compacting machine. A third control may be effected, e.g. switching off of a boat engine, by movement of the outer casing of one of the flexible cables. To this end the outer casing is grooved at 21, Fig. 10, so that it is retained in a housing by a pin 7. Movement of the pin against a spring (not shown) to bring a concave portion 7a into alignment with the outer casing allows the latter to be moved downwardly by rotation of a handle 8 connected to a crank-pin 8a engaging the groove 21. It is stated that more than one flexible cable may be connected to a single carriage, and also that the slots 12f, 13f may differ from each other in direction and configuration, e.g. each slot may be of arcuate form.

Filed: 1926-11-18
Abstract: 267,085. Dieckerhoff, E. C., (Assignee of Werder, H.). March 4, 1926, [Convention date]. Bell cases; bell strikers; bell-operating mechanism, hand and mechanical; plate vibrators. - Warning devices for vehicles comprise a number of sounding members such as bells mounted on a rotatable axle and brought into the path of a stationary striker. In one construction, Figs. 1 and 2, four bells 12 secured to an axle 7 are rotated by a hand crank 16 through gearing 9, 15 so as to strike a pivoted spring-controlled striker 21. The casing 1 is in the form of a surface of revolution with a hole at the top to which a horn 4 is fitted. In modifications, the axle 7 may be driven by an electric motor either through worm gearing or by mounting the bells directly on the field magnets so as to rotate therewith, or the axle may be driven from the engine through a friction clutch controlled by a rope from the driver's seat. In another construction, Fig. 5, the bells 12 are mounted obliquely so that only one edge engages the striker 21, and the axle 7 is rotated by a spring-controlled push-rod 33. Alternatively, the bells may be mounted symmetrically, the single operation of the bells being obtained by raising one edge of the rim. A number of sets of bells may be arranged on a single axle. The sounding members may be suitably tuned to give a pleasing musical effect. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction in which the bells are fixed to the inner wall of the casing, a series of resilient strikers being arranged on the rotating axle 7, and a further construction, Fig. 9 (Cancelled) in which the sounding members are steel bars 40 which are struck in succession by strikers 41, the axle 7 being rotated by a hand crank 42 through gearing 43. This subject-matter does not appear in the Specification as accepted.

Abstract: 564,793. Selective systems. YARDENY, M. Nov. 3, 1939, No. 29349. Addition to 524,410. [Class 40 (i)] In order to avoid hunting and overrunning the stop points on the contacts in the parent Specification, the motor shaft a<1> is connected to the shaft a<3> of the tuner through resilient members j<1>, d provided on one or both shafts. In the example, a reduction gear p, r is also provided. If desired, the knob b moving the pulley p direct may be given end play so that, on pressure, it actuates one end of a lever, forcing prongs on the solid part f of the resilient member d into corresponding holes in the drum r of the reduction gear, to give a positive drive for hand adjustment. In addition to the stopping effort of the motor due to opposing currents, as described in the parent Specification, the brush 17 borne by the selector shaft may be springy through attachment to the selector disc 1 near its centre and may be provided with a ball 22, coacting at the ends of the contacts 9, 10 with a circular depression to exercise a mechanical braking. Another feature is that the breaking of the circuit of the motor when the selected station is reached, by a relay as described in the parent Specification, is delayed as by coating the engaging surfaces with adherent material such as rubber. It is also stated that the drive for the selector discs may be effected from a universal motor, made so that when an impulse current has been sent through the windings by a push-button, the shaft is moved axially to complete and hold the circuit closed until the end of the tuning operation.
