Title: A cleaning device for pipes
IPC: B08B9/04
Filed: 1959-12-04
Abstract: 905,007. Pipe cleaning devices. LEMFORDER METALLWARENGESELL SCHAFT. Dec. 4, 1959 [Dec. 4, 1958], No. 41332/59. Class 99(2). The internal surface of a pipe 1 is cleaned by a fluid propelled device comprising a support member 2 on which are mounted interchangeable, spaced apart annular stripping elements 5 made of rubber or synthetic plastic, e.g. polyurethane, and having an external edge 6 which bears against the surface of the pipe and remains in sliding contact therewith during cleaning, the member 2 being of cylindrical tubular form through whose bore 7 a portion of the fluid may flow so as to travel along in advance of the device during cleaning. The member 2 is provided with grooved collars 3 in which the elements 5 are fitted. An interchangeable nozzle 9 is fitted in the bore 7 to regulate the flow of fluid through it and hence the speed of travel of the device in the pipe, The member 2 may be. made of synthetic plastic which is softer than that of the elements 5. In a modification, the support member consists of a number of cylindrical elements flanged at both ends and bolted together, the stripping elements in the form of perforated discs being secured between the flanges and, by blind flanges, at both extremities of the support member. In a further modification, the support member consists of only one flanged cylindrical element.

Title: Pattern generating system
IPC: G09G1/20
Filed: 1971-09-06
Abstract: 1327695 Cathode-ray tube displays ISE ELECTRONICS CORP 6 Sept 1971 [7 Sept 1970] 41406/71 Heading H4T In a cathode-ray tube pattern (e.g., Alpha- Numeric) display system employing a tube of the kind having a "dot" apertured matrix electrode assembly positioned within the tube between the cathode and the screen the patterns being produced by selective energization of the X and Y axis electrodes of the assembly a plurality of pattern signal generators are operated independently to effect the energization required to produce respective different patterns and are operated simultaneously to display modified patterns synthesized from the different patterns. Figure 8 shows an example of this in which the character "E" is synthesized by the simultaneous over-lapping production of the characters "F" and "L". One of the pattern signal generators may produce only a partial pattern which may be combined with the pattern produced by another generator to produce a modified pattern. Figure 7 shows an example of this in which the character "F" is modified by the addition of a partial pattern comprising the elements 7a to 7e of Fig. 7(a) to produce the modified pattern comprising the character "E". The matrix electrode assembly comprises a shield plate 7 (see Figs. 1 and 2) disposed between X axis electrodes 5a to 5g and Y axis electrodes 6a to 6e the whole assembly being apertured at the crossing positions of the X and Y electrodes so that when clock pulses a to e (Fig. 3) are supplied to terminals 11 to 15 respectively the diode pattern-signal generating circuit controls, in known manner, the trans. mission of electrons such that a pattern, in this case the character "H" (Fig. 4, not shown) is produced on the tube screen 2. Fig. 5 shows a further known pattern-signal generator in which terminals 50 to 54 correspond to terminals 11 to 15 and conductors 86 to 92 correspond to conductors 38 to 44 in Fig. 2, the generator including AND gates 60 to 64 which, when conditioned by a select input on conductor 70, supply outputs via OR gates 72 to 78 for producing the character "E", additional AND gates 65 to 69, conditioned by a select input on conductor 71 and associated OR gates 79 to 85 serving for the production of the character "F" and this known type of generator is modified as shown in Fig. 6 to provide the operation required by the invention. Referring to Fig. 6, AND gates 65 to 69, operate via OR gates 93, 94 and 97 to 106 to produce the character F (Fig. 7b) when conditioned by an input on conductor 71. When the latter input is removed and a conditioning input supplied to conductor 70 AND gates 61 to 64 operate via the OR gates 93, 94 and 98 to 106 such that a modified character "F" without the element le (Fig. 7b) is produced, AND gate 60 operates via OR gates 95 and 96 to produce the elements 1e and 7e and AND gates 61 to 63 operate additionally via OR gate 96 to produce the elements 7d, 7c and 7b and thus synthesize the character "E" from the modified character "F" produced by the generator 107 and the partial character produced by the generator 108.

[Also in Division H2] A synchronous motor driven from a transistor oscillator circuit is synchronized to a signal from an external source which is applied through a coupling transformer to the oscillator circuit by having the secondary winding of the transformer connected in series with the feedback coils of the oscillator. Motor field coils 243, 243<SP>1</SP> are connected in series with battery 245 in the output circuit of transistors 242, 242<SP>1</SP> respectively and feedback coils 244, 244<SP>1</SP> are connected in series with the secondary winding of transformer 247 in the transistor input circuits to form an oscillatory circuit for driving permanent magnet rotor 249 at a speed fixed by the values of the circuit parameters. If a signal 246 is applied to the primary winding of transformer 247 the driving circuit will oscillate at the signal frequency and the speed of the motor will be synchronized with the applied signal. By means of the circuit 248 the bases of the transistors may be biased to maintain the motor output constant thereby reducing the power consumption. In alternative arrangements the same result may be obtained by a detector circuit placed in the output stage, Fig. 3 (not shown), or a proportion of the battery voltage used to bias the base circuits of a pair of transistors which are coupled through a transformer to the driving transistors, Fig. 4 (not shown). In order to stop the motor, switches may be provided to either short circuit the field coils or to reverse the polarity of the feedback signals applied to the bases of the transistors, Figs. 6 and 7 (not shown). An A.C. supply may be used instead of a battery and it is stated that semi-conductor controlled rectifiers could be used as the switching elements.

In a printed circuit comprising a plurality of conductive patterns deposited in succession on an insulating substrate, vertically adjacent patterns are insulated from one another where desired by the interposition of a local patch of insulating material at the crossover point. As shown, a first wiring pattern 2a, 2b, 2c is formed by vacuum deposition through a mask on a glass substrate 1. Local insulating patches 3a, 3b, 3c, 3d of, e.g. SiO are then deposited on the first wiring pattern at points where it is desired to insulate it from a subsequent pattern. A second wiring pattern 4a, 4b is next deposited, being insulated from the first pattern at 3a, 3b, 3d, but being electrically connected to it at unprotected crossover 5. Further insulating patches 6a, 6b are formed, followed by a third wiring pattern 7 which contacts conductor 2c at 8 but is otherwise insulated from previous patterns by patches 3c, 6a, 6b.

Title: Process for separating solid components from fats
Inventor: SMITH WILLIAM ALEXANDER
IPC: C11B7/00
Filed: 1963-11-01
Abstract: A process for separating solid components from fats comprises heating the fat to a temperature at which it is substantially completely liquid; rapidly chilling the liquid product to produce a cloud of crystal nuclei; slowly cooling the nucleated product to a temperature at which the high melting components and a desired proportion of the intermediate melting components have crystallized; and thereafter separating the fat into substantially solid and substantially liquid components.  In the example, hardened herring oil is heated to 120 DEG  F. and passed through a scraped wall heat-exchanger where it was chilled to 85 DEG  F. in 18 seconds, the chilled oil then being cooled to 60 DEG  F. in a further 5 hours in a jacketed cooling vessel.  The product was filtered under suction, the filter cake amounting to 55 wt. per cent of the product.
