Abstract: 905,090. Variable-speed friction gear; expanding-wheel gear. BATTISTIN, F. Oct. 14, 1960 [Oct. 29, 1959], No. 35260/60. Class 80 (2). In a variable-speed friction gear for motor vehicles, wherein conical driving (or driven) discs such as 8, 7, 11 frictionally engage driven (or driving) rings such as 13, 14 and the ratio is varied by varying the distance between the rotational axes thereof, each ring comprises and retains therein two sets of rotatable, cylindrical rollers 2, 3 which are tangentially arranged in circumferentially equispaced, parallel, contacting pairs, and project from the sides of the ring to engage the discs. The rollers may be hollow or pierced and their height is preferably less than their diameter. As shown, an intermediate shaft 12, transversely movable with respect to coaxial input and output shafts 10, 18, carries driven rings 13, 14 engaging input shaft driving discs 8, 7, 11 and driving discs 15, 16, 17 engaging output shaft driven rings 19, 20. The discs 7, 11 and 16, 17 have limited axial movement on their respective shafts 10, 12 and are loaded to engage the rollers 2, 3 by helical or, as shown, cup springs 25. The rings 13, 14 and 19, 20 have guide ribs 23 for limited axial movement within bell housings 21, 22 respectively secured to the shafts 12, 18. The intermediate shaft 12 may be moved automatically by output speed responsive means. In Fig. 8 each pair of rollers is seated in an inner ring member 31 and, together with a retaining bridge 35, is circumferentially located by closely-arranged radial grooves 36 in the bell housing. Each bridge 35 is an accurate sliding fit in its groove for slight axial movement of the rollers and bridge in the bell housing which comprises annular recesses such as 33 accommodating the discs.

Title: Telephone message apparatus
IPC: H04M1/65
Filed: 1929-11-19
Abstract: 341,194. Substation equipment. ZULLO, S., 757, Bergen Avenue, Jersey City, New Jersey, U.S.A. Nov. 19, 1929, No. 35368. [Class 40 (iv.)] In systems in which when the called party is absent a message is transmitted mechanically to a caller and the caller's reply is recorded on a cylinder, an instrument of the type known under the Registered Trade Mark "Dictaphone" is used, the instrument being fitted with a single cylinder and with two sound boxes, one sound box transmitting the message recorded on the record and returning to its normal position after each call and the other recording the caller's reply. The second sound box moves a definite distance for each call, a pointer, attached to it and moving over a calibrated scale, indicating how many messages have been received. When a call is received relay 93, Fig. 4, energizes completing a circuit for magnet 67 to pull up. Magnet 67 by means of the chain 66 pulls down the pin 64, moving cam 59 anticlockwise to allow the lever 29 to raise the receiver 12 and to start the dictaphone motor. The two sound boxes 21 and 35, which are connected to the telephone by speaking tubes 22 and 36, move along the rod 19, the box 21 dictating the message recorded on the cylinder 17. When the message is finished the sound box is unclutched from the rod 19 and moved back to its initial position, but the sound box 35 continues its travel and records a message from the calling subscriber. When the sound boxes began to move, the head 78, Fig. 2, moved to the left raising the arm 74 which tilts rod 72 to remove the catch 55 from the wheel 52 and to release the governor shaft 76. The timing device motor 47 drives the wheel 52 at a speed regulated by the governor. When wheel 52 has made a complete revolution the catch 55 re-engages the wheel 52 and the pin 54 moves the pivoted lever 69 which raises arm 65 and thus moves cam 59 in a clockwise direction. Arm 29 is restored to normal to disconnect the calling line and to stop the dictaphone. The pointer 96 moves one division of the scale 95 for each call.

Patent GB-757479-A (GB)
Title: A process of preparing egg products
IPC: A23B5/005
Filed: 1954-12-08
Abstract: In preparing egg products, eggs are treated with an acid liquid medium to dissolve the shell or render it incoherent and leave the surrounding membrane intact, the treated eggs are separated from the acid liquor and the undissolved shell is removed, e.g. by rinsing with water.  The acid may be normal hydrochloric, acetic, lactic, citric or sulphurous, to which cleansing agent, detergents and disinfecting materials may be added.  The treatment is preferably effected below the coagulation temperature of the egg-white.  The eggs may be slowly moved in countercurrent to the acid liquid in an inclined tube, the evolution of the gas caused by dissolving shell thereby assisting the movement of the eggs. The treated egg may then be dried in a current of hot air or other gas, or by heating in vacuo, and the white and yolk of the dried egg subsequently separated.  Alternatively the treated egg may be frozen or the membrane may subsequently be destroyed and the egg material worked up by conventional methods.

Filed: 1933-12-21
Abstract: 422,150. Refrigerating and heating. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 21, 1933, No. 35975. Convention date, Dec. 21, 1932. [Class 29] Absorption systems.-Apparatus operating on the principle of continuous cycle or reversing absorption refrigerating systems is adapted for abstraction or emission of heat in at least four distinct temperature ranges, as distinguished from the usual three ranges of the generator, the condenser or absorber, and the evaporator or low temperature generator. The heat given out may be employed to generate steam for turbines, or for general heating purposes, while heat may be abstracted from refrigerating chambers. Apparatus comprising two linked reversing systems out of phase is shown in Fig. 1, in which generatorabsorber vessels KA<1>, KA<2> receive heat alternately from a furnace 1 at a temperature T<8>, through closed heat-transfer systems 2, 3, 4, with reversing valves 5, 6. The associated condenser-evaporator vessels CV<1>, CV<2>, transmit heat of condensation through closed transfer systems 26, 25, 28 to a coil &c., 31 at a temperature T<1>, and heat of evaporation is supplied to them from a refrigerator 21 at a temperature T<0> through transfer systems 22, 20, 19. The heat of absorption of the generator-absorber vessels is transferred through systems 10, 9, 8, to a steam generator 7 at a temperature T<2>, the steam being delivered to a turbine 14, and condensed at 16, whence the condensate is returned by a pump 18. Refrigeration is produced at a somewhat higher temperature than with the usual systems, external work is performed by the turbine, and useful heat is given out to the coil, &c., 31. Water may be used in the high temperature transfer system and sulphurous acid or ammonia in the low temperature system. Solid absorbents, such as strontium bromide, which combine with the refrigerant may be employed in the reversing systems. The method may be applied to non-condensing reversing systems. Continuous-cycle systems of the condensing or reabsorption types may be employed, with water or ammonia as refrigerant and caustic soda, potash, or zinc chloride as absorbents. A system with six temperature ranges, T<0>-T<5>, Fig. 5, includes a generator 301 supplying vapour to a condenser 308 and to a reabsorber 306, an evaporator 311, a low-temperature generator 317 and an absorber 316. Heat of absorption in the absorber and reabsorber is used to generate steam in vessels 318, 319 for stage turbines M<3>-M<5>, the exhaust steam being condensed in vessels 328, 331 cooled respectively by a heat transfer system 341 from the low-temperature generator 317 and by an external source 332. Liquor and condensate pumps P<8>-P<12> and control valves V<21>-V<29> are provided. The relative amounts of refrigeration and power produced depend on the proportions of vapour from the generator delivered to the reabsorber 306, and to the condenser 308, and it is stated that varied thermal effects may be produced by varying these proportions.

Abstract: 1368839 Vibrators MASCHINENFABRIK BUCKAU R. WOLF AG 2 Aug 1972 [10 Aug 1971] 36161/72 Heading F2X A mechanical vibrator for use with, for example, vibrating plate or cylinder compactors or shaker-type rollers comprises two roller-type eccentric masses relatively adjustable on a circular path concentric with a driving shaft by means of which the masses are rotated. The eccentric masses are, in the embodiment illustrated, formed as cylinders 7, 8 housed in an annular duct 6 provided by a cylindrical housing 5 with end plates 3, 4 fixed to a cylindrical boss 2 of the driving shaft 1. Cylinder 7 is locked fast in the duet 6 by means of a threaded pin (at 9a) while cylinder 8 is freely movable over a path of about 180 degrees between the locked cylinder 7 and a threaded pin 9. On rotating the vibrator anticlockwise, the pin 9 strikes against the cylinder 8 which is thereby positioned opposite the cylinder 7 and the vibrator is balanced. The means for producing an unbalance comprises a supply bore 12 and a return bore 13 provided in the shaft 1 and boss 2, the supply bore 12 being connected to a pump which takes oil from a storage tank, the return bore 13 also being connected to the storage tank. If now a stream of oil is pumped through the bore 12 into the annular duct 6, the cylinder 8 is moved from the pin 9 towards the cylinder 7, maximum unbalance occurring when the cylinder 8 bears against the cylinder 7. By regulation of the oil  flow, it is possible to adjust the position of the cylinder 8. In an alternative embodiment (Fig. 3, not shown), the annular duct is divided by two partitions offset by 180 degrees to form two duct halves in each of which is disposed a cylinder. The supply and return bores each span into transverse bores extending through the partitions. In the balanced condition, the cylinders are each in contact with one of the partitions and thus spaced by 180 degrees but on supplying oil under pressure to the supply bore one of the cylinders is displaced towards the other thus creating an unbalance.

Nov. 28, 1929, No. 36497. Convention date, Dec. 20, 1928. Drawings to Specification. [Class 98 (ii).] Relates to combined kinematograph and soundrecord films, and more particularly to such films in which the pictures are in natural colours. According to the invention, the photographic sound-record in its final form, instead of being a developed silver image as usual, is formed as a dye relief image or as an imbibition print therefrom. The soundrecord may be either of the varying density or varying width type. The dye used, which may be one of those used in forming the colour pictures, is preferably of such a kind that it is confined substantially to the surface of the gelatine, so as to improve definition. Examples of suitable dyes are specified. Contrast may be enhanced in the relief sound-record by etching off all the gelatine adjacent to the record, leaving bare celluloid, which will not imbibe the dye. A preferred process is as follows. From sound and picture negatives, produced on the same or different films, positives are printed, with a separate positive for each colour aspect in the case of colour pictures, the sound-record being preferably made on one or more of the positives bearing the pictures. Both the picture and sound positive images are then converted into gelatine reliefs (e.g. by exposure through the celluloid backing, hardening, bleaching, and dissolving off the unexposed gelatine, as described in Specification 188,329, [Class 98 (ii), Photographic processes &c.]) after which the matrix images are dyed and printed on to a blank film by imbibition (e.g. as described in Specification 307,659, [Class 98 (ii), Photographic processes &c.]) the sound-record preferably being printed simultaneously with the pictures. Before exposure of the positive film, it is preferably dyed with naphthol yellow or quinoline yellow (as described in Specification 263,650, [Class 98 (ii), Photographic processes &c.]) or a small amount of sodium bichromate is added to the gelatine emulsion in order to sensitize the emulsion for the more actinic portion of the exposure light.
