Title: A process for operating continuous sugar centrifuges and sugar centrifuges for use in such proces
IPC: B04B11/02
Filed: 1962-09-28
Abstract: 971,234. Centrifuges. BRAUNSCHWEIGISCHE MASCHINENBAUANSTALT. Sept. 28, 1962 |Nov. 24, 1961], No. 36858/62. Heading BID. In the operation of continuous sugar centrifuges with substantially conical centrifuge cages, over the screening surface of which the layer of material being centrifuged is transported, the said layer of material is heated over its entire height, thereby increasing the output of the centrifuge. The layer of material being centrifuged may be heated, at least in the region of the top edge of the centrifuge cage, to the limit of the solution temperature range used in the production, thereby regulating the centrifuge to optimum output. Preferably said layer of material is heated as uniformly as possible over its entire height, suitably to 52-80 C. and especially 65-75 C., and air circulation, and currents of air between the inside of the cage, the molasses compartment, and/or the sugar compartment, particularly those passing through the layer of material on the centrifuge, are prevented. Heating may be effected frictionally, or by external means, e.g. by admitting steam or hot air into the molasses compartment, or by dielectric heating. Heating media, e.g. steam or hot air, are preferably admitted to said compartment in the region of the narrowest cross-section of the centrifuge cage. Control instruments may be used to measure the temperature of the layer of material as close as possible to the top edge of the centrifuge cage, e.g. placed suitably in the molasses compartment, and thereby effect regulation of either the layer thickness, i.e. input rate if frictional heating is used, or of the energy input, if external heating is used. Apparatus as shown comprises a substantially conical screening surface and centrifuge cage 2 arranged inside a housing, surrounded by the molasses compartment 4 and communicating over the top edge with the sugar compartment 5, the casing being enclosed by top and bottom covers 12, 13 and a baffle, suitably an extended sugar crystal deflector ring 14, being inserted in the region of the gap between the sugar compartment and the centrifuge cage, the baffle extending into the cage to a position in which it makes sealing contact with the layer of material being centrifuged. The material feeder 11 may also be fitted with a baffle 15. In the apparatus of Fig. 1, heating is effected by friction. That of Fig. 2 includes an inlet pipe 17 connected to a mixing valve 21 and control valve 22, and a source of steam or hot air at 22a and cold air at 22b, the control valve being regulated by a temperaturesensing device 19 in the molasses compartment to maintain a constant temperature therein. In Fig. 3, the centrifuge cage or its screen surface constitutes an electrode for dielectric heating and a counter-electrode 18 is mounted inside the centrifuge cage, 20 being a temperature-sensing device.

In a calculating or similar business machine, having a printing mechanism and a shoot for receiving a manually inserted record material (e.g. cheque) for printing upon, a device for ensuring the precise positioning of the record material with respect to the printing mechanism and including a marginal abutment for one margin of the record material located within the shoot, the abutment being shiftable longittudinally of the shoot from a first position to a second position precisely defined with respect to the printing mechanism, and a shifting mechanism for the abutment actuated at the commencement of each cycle of machine operation, whereby record material manually inserted in the shoot with one of its margins located between said first and second positions of the abutment will be shifted longitudinally of the shoot to locate said one margin in said second position. The shoot 25 comprises front and rear plates 28, 27, spaced apart by strips 30, 32. The front plate 28 includes a transparent portion 29. The front and rear plates are cut-away at 28b to receive the marginal abutment 34. The latter is reduced at its lower end 34a to slide between said plates and has V-shaped portions 35, 36, Fig. 4 (not shown), adapted to engage the marginal edge of the cheque. The marginal abutment is adjustably secured to an L-shaped rod 40, which is moved to the left at the start of each machine cycle, whereby the cheque is registered accurately in position with respect to the printing mechanism 33. The front and rear plates are cut-away at 28a, in the region of the printing mechanism and platen 14. In addition, the front plate 28 is slatted at 28c to form clamping fingers 55. Said fingers are pushed out of the plane of the front plate by reciprocating slides 56a, to clamp the cheque against the platen 14 and hold it in its registered position during printing. The slides are slotted at 57, Fig. 5, and are mounted on fixed studs 58. They are held in their inoperative position by springs 59 attached to the foremost studs 58 and studs 60 on the slides. The slides are reciprocated by two levers 62 pivoted at 61. The upper end of each lever is attached to the stud 60, on the associated slide, by a spring 65. In operation, a main shaft 15 is oscillated once for each machine cycle by a handle or an electric motor. A cam 50 fixed to said main shaft reciprocates the rod 40, to position the cheque, through the agency of linkage 41, 46-52, Fig. 1 (not shown). Cam arms 66 on said main shaft co-operate with the levers 62 whereby the slides 56a are reciprocated. Finally, hammers 18 are released near mid-cycle of machine operation to strike selected type members 19.

[Also in Division H1] A radiation beam which partially melts and partially evaporates part of an electrically conductive film, causing it to flow through an aperture made by the beam in a non-conductive film by the beam and adhere to another conductive film is used to reduce the resistance of resistor 20. A laser pulse for example, may be used to make a hole 41 through conductive films 27 and 22 and non-conductive film 26, with an inner wall lined with conductive material originally from film 27, so forming an electrical connection between films 27 and 22. A higher-power laser pulse of shorter duration may be used to make an unlined hole through all three films, or through films 26 and 22 where they are not covered by film 27 and so increase the resistance between terminals 23 and 24. Electron beams, ionic beams and infra-red beams may be used in place of laser pulses. The resistor 20 comprises a first film 22 of conductive material, a pair of terminals 23, 24, a film 26 of non-conductive material over at least a portion of the first film 22 and a second film 27 of conductive material over at least a portion of the non-conductive film 26 and the first film 22. Its resistance is reduced to a desired value by so forming at least one electrical shunt connection physically located between the conductive films. Film 27 may be in contact with terminal 24 as well as with terminal 23, or with neither, in which case two or more lined holes are required to complete the resistor. Film 22 may be of Ta on a sapphire substrate 21, film 26 may be of Ta pentoxide and film 27 may be of Ni-Cr alloy. The terminals 23 and 24 may each comprise successive layers of Ni-Cr alloy and Au. Film 26 may be made by anodizing the surface of film 22.

Abstract: 1,096,693. Making metal shot. TEXTRON Inc. Aug. 31, 1966, No. 38811/66. Heading B3A. In a method of making fine metal shot, randomly sized metal shot particles are segregated into groups by size, a selected group of a coarser shot is crushed to form grit and the grit so formed is repeatedly impacted until formed to the approximate spherical shape of the fine shot. The shot, before being crushed to grit is usually hardened to over 64 on the Rockwell " C " scale and after crushing is tempered to 35-55 Rockwell " C." A measured amount of tempered grit is fed from a storage bin 90 into a hopper 70 whereupon a conveyer 55 carries the grit to a surge hopper 50. A valve 51 controls the feed of grit to an impeller 40 which ejects the grit on to targets 80, 86, 87 or a baffle 64. The material passes through holes in the baffle into an air wash bin 66 which leads to the hopper 70 or to a discharge conduit 69 via a valve 67. A conduit 72 leads to a dust collector which includes an abrasive trap 73 wherein a baffle 76 deflects larger particles into the hopper 70 via a pipe 74. The grit is recycled through the apparatus until shot of the required size is formed.

Abstract: 1,070,735. Feedback control systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept.25, 1964 [Sept.25, 1963], No.39208/64. Heading G1N. The response characteristics of a second order feedback control system such as a mechanical position servo are optimized by attenuating at 12, Fig. 5, the signal from the input 10 before it is applied to the actual feedback circuit, 14; detecting when the output at 16 first ceases to change in value during its response to the attenuated input and, at this stage, removing the input attenuation by closing a switch 124. The net response is thus the sum of the responses to two signals, the sum of which signals is equal to the input signal, but which are separated in time from one another. In the mechanical servo shown, a motor 142 drives the output 163 which is a wiper on a potentiometer. The motor output speed is measured by a tachometer 181, and a detector 182 operates only when the tacho output is zero in order to actuate a relay 123 and thus switch in a resistor 121 to reduce the attenuation. The attenuation initially applied is of the order of 2:1.
