Title: Improvements in or relating to machines for applying cream and like materials to biscuits and the like
IPC: A21C15/00
Filed: 1927-08-11
Abstract: 285,739. Peek Frean & Co., Ltd., and Rondolin, L. Aug. 11, 1927. Flat endless-band conveyers. - In machines of the kind wherein material, such as cream &c., is applied to biscuits &c. automatically from a hopper 10 with 'the aid of an endless supporting band 4 and an endless stencil band 1, one or each of these bands is so made that it does not have to be maintained in tension. As shown, the flexible band 1 consisting of appropriate gauge metal with or without a rubber covering is cut to provide or carry stencils and is arranged to travel in a circular path passing between the supporting band and the hopper. The band 1 passes loosely around guide-rollers 5 each of which is adapted to be retracted axially against the action of a spring for the positioning or the removal of the band, the hopper 10 being detachably secured as by nuts 12. The invention is particularly applicable to mechanism wherein one band is used to drive another directly as in Specification 240,104, [Class 28 (i), Bread-making &c.], and for this purpose the teeth of the lower band 4 may act against metal clips clinched over the driving edges of the holes in the band 1.

Abstract: 658,607. Paper and like bags. FAIRWEATHER, H. G. C. (American Bag & Paper Corporation). Aug. 15, 1949, No. 21223. [Class 94(ii)] In forming a self-opening rectangular bottom bag from a flattened tube 10 of paper or the like with bellows folds along each side, one wall is provided with two symmetrically disposed longitudinal cuts at one end, spaced from the sides to form a tab or tongue 14 so that when that end is formed into a diamond fold, as shown in Fig. 9, with a pair of longitudinal flaps 15, the end portions 16 of these flaps are united by a vertical fold or crease, and the tab 14 remains as a projection to form a closure member after further folding of the bottom of the bag. The bag is preferably of the kind provided with an impervious lining 11 of thermoplastic material, both bag blank and lining being comprised initially by inner and outer tubes which are cut and folded together and, with the flaps 15 standing vertical to the rest of the bag heat is applied along their length to cause the abutting inside faces of the relative portions of. the lining to adhere together. The flaps 15 are next folded downwardly to lie flat upon the adjacent portion of the bag bottom, Fig. 8, after which heat is applied transversely across the protruding portion 17, Fig. 3, and the triangular portion 20 of the diamond folded bottom is bent over along a crease line 21, Fig. 5. Finally the portion 17 with the tab 14 is folded inwardly along the line 19, and the tab is secured to the portion 20 by adhesive. The lining may consist of material other than thermoplastic in which case an adhesive is applied between the abutting faces at the requisite places.

Abstract: 597,459. Electromagnetic switches. PLESSEY CO., Ltd. Aug. 20, 1945, No. 21252. Convention date, Aug. 18, 1944. [Class 38(v)] In a vibratory interrupter wherein a driver coil 12 maintains a reed 14 in vibration, a deformable member 24, mounted on the reed, is adapted to be bent so as to adjust the operating frequency of the interrupter. In the Fig., this member comprises a T- shaped ferro - magnetic plate 24 clamped to the armature 15 so as to compensate for fluctuations of operating voltage by lessening the effect of the coil 12 on the armature. In a modification, Fig. 3 (not shown), the deformable member is of non - magnetic material, such as brass, and acts by changing the effective mass of the vibrating system upon bending the part 24. In Fig. 5 (not shown), the deformable member is a bimetallic plate, whose free part, which is preferably normally arranged at rightangles to the reed, bends upon temperature changes to compensate for such changes. In further modifications (not shown), combinations of these various embodiments are described.

Title: Method of producing homogeneous ingots of metallic alloy
IPC: C30B11/00
Filed: 1971-04-19
Abstract: 1316406 Casting processes TEXAS INSTRUMENTS Inc 19 April 1971 [16 Feb 1970] 21263/71 Heading B3F [Also in Division C7] An ingot of an alloy containing a component of relatively high vapour pressure compared with the other components of the alloy is prepared by heating the components together to form a homogenous liquid mixture, in a sealed chamber containing a vapour space and quenching the alloy from a liquid to a solid while maintaining a high vapour pressure in the vapour space. In the examples, Hg-Cd-Te alloy is prepared by melting appropriate quantities of the component elements in a quartz ampoule 16 which has been etched, rinsed with deionized and distilled water and vacuum fired. The component elements are loaded into the ampoule in a glove box filled with N 2  and before sealing with an H 2 /O 2  blowtorch the ampoule is evacuated. After heating for 24 hr. in a rocking furnace 10 at 810 C., the alloy is quenched by directing a stream of N 2  on the ampoule base through a tube 32 while maintaining the top ampoule end and the vapour space 20 by a refractory heat-insulating shield 22. Alternatively, the lower end of the ampoule is lowered into a quenching oil while the upper end is surrounded by a heat shield. The heat shield can include an electric heater. The heat shield may be replaced by a heat sink.

Apparatus for the mass chromium-plating of metal parts or articles comprises an electrolyte container 12, Fig. i, the axial inclination of which is adjustable, within which is mounted an openwork basket 10 to receive the articles and serving as cathode connection thereto, the basket being inclinable with the container and rotatable relatively thereto. As shown the container has double walls through which cooling liquid is circulated. The basket 10 is rotated by a shaft 7 mounted in a flange 11 on the container 12 and driven through a worm 8 and worm wheel 9 from a mechanically driven shaft 2; the shaft is enclosed within a column, not shown, upstanding from the bottom of the container and extending above the electrolyte level to prevent access of liquid to the shaft bearing. The flange 11 together with the shaft ,7 and worm wheel 9 are mounted on a member 3 journalled on a stand and provided with a worm wheel segment 4 whereby it may be pivoted about the axis of the shaft 8 by means of a hand wheel 5 and worm 6. A worm conveyer 21 is mounted between the inner wall of the basket i and an inner cylinder ioa whereby on rotation of the basket in the appropriate direction on completion of the plating operation the articles are conveyed to the upper rim of the basket and fed into a sieve 22 to drain. The anode 28 is mounted adjustably within the basket 10 according to the amount of the work present therein; connection is made thereto by a bar 27 insulatedly fitted to the pivot member 3. Cathodic connection is made to the shaft 7 by a brush engaging a slip ring 26, and thence through a pipe 20 surrounding the column above referred to, to the basket 10. Electrolyte vapour is withdrawn by suction at 24. In a modification, Fig. 3, the basket driving shaft 32 is hollow and connection to the anode 34 is made through a bar 33 mounted in insulating bushes 30, 31 in the shaft; the shaft is surrounded in turn by the column 13 for preventing access of liquid to the bearings and by the pipe 20 conveying the cathode current.

Abstract: 1,272,178. Arc welding systems. LINDE A. G. 5 May, 1970 [6 June, 1969], No. 21505/70. Heading H2H. An A.C. welding arc or D.C. arc, is stabilized or struck by means of a high current pulse produced by discharging a capacitor, through a silicon controlled rectifier, whose control circuit contains a diac. A storage capacitor 10 is charged via a rectifier 8, and has a silicon controlled rectifier 15 in its discharge circuit, which includes pulse transformer 14 connected to electrode 3 and workpiece 4. Blocking capacitor 12 and inductor 13 function as commutators for the thyristor. The thyristor 15 is switched to a conducting state when the A.C., or D.C. input voltage reaches a certain magnitude. The magnitude at which the thyristor is fired is determined by means of potentiometer 27, and diac 20. Repeated firing of the thyristor 15 during a half cycle of an A.C. welding current, is prevented by means of a second thyristor 23, which shorts out capacitor 19 when it is triggered to the conducting state by the first output pulse passing diac 20. This circuit is inoperative if switch 26 is opened, The circuit just described only provides positive pulses. If pulses of alternating polarity are to be provided thyristor 15 is replaced by two thyristors arranged in anti-parallel, and each having its own control circuit, or by a triac.
