Abstract: 1,049,375. Electric toasters. MORPHYRICHARDS Ltd. Aug. 15, 1963 [Aug. 23, 1962], No. 32368/62. Heading A4D. In an electric toaster of the pop-up type, in which the bread carrier is retained in the lowered position by a two component latch, the latch members are released either, by one member moving independently about one axis, or by both members moving in unison about the other axis. As shown, a bread carrier 2 has a pin 10 which engages in a hook 13 to secure the carrier in the lowered position. Tension spring 4 pulls upwardly on hook 13 its line of action passing through the pivotal connection 13a of hook 13 to plate 14, Plate 14 is pivotally mounted on the toaster frame at 14a and is prevented from pivoting by catch 15 restraining its tail. On expiry of the toasting period, solenoid 16 is energized to release catch 15 and allow hook 13 and plate 14 to turn in unison about pivot 14a, thus releasing pin 10. Spring 4 drives carrier 2, bracket 8 and dash-pot piston 7 upwardly. In order to re-set the latch. the carrier 2 is moved downwardly by means of a handle attached to yoke 3 extending from bracket 8. The toasting may be interrupted at any time, by lifting bracket 8 upwardly, so that lostmotion between it and the carrier 2 allows striker 9 on the bracket 8 to rotate hook 13 about pivot 13a and so release pin 10.

Title: Method of forming low friction greaseless bearings
IPC: F16C23/04
Filed: 1960-09-21
Abstract: 919,223. Making composite bearings; jointing. KAHR BEARING CORPORATION. Sept. 21, 1960 [March 18, 1960], No. 32405/60. Classes 83 (2) and 83 (4). A method of forming a low-friction greaseless bearing comprises placing within a tubular outer race member 5 a thin resilient and complient sheet of woven fabric material 7, e.g. cotton, nylon, having a surface weave of fibres of a polymer of fluoroethylene, e.g. tetrafluoroethylene, exposed on one side and an adhesive backing of a phenolic-thermosetting resin on the other side, said adhesive backing being positioned against an inner wall of said outer race; inserting an inner bearing member 6 within said tubular outer race member with said fibres facing outer portions of said inner member; applying forming pressure to said outer race member to permanently deform it about said inner bearing member and to produce an assembly wherein said inner member is tightly held by said formed outer race member; and relieving said forming pressure and then applying heat to said assembly to cause said adhesive backing of said compliant sheet to become bonded to said inner wall of said outer race. The outer race member 5 when used in a spherical type bearing is of stainless steel and has a ring-like profile as shown at 5, Fig. 3. The inner surface of the outer race member is rough machined or sand blasted to facilitate bonding. Predetermined roughness may be obtained by boring or turning a very fine thread in said inner surface. The outer surface of the inner member 6 is buffed, chrome-plated. rebuffed and then dipped into a silicone or wax emulsion and baked at 365‹ F. for a few minutes to provide a lubrication film about 0.0125 mm. thick. The outer race member is formed about the inner bearing member by means of an extrusion die 10, Fig. 1, or forming dies 10<SP>1</SP>, Fig. 2. After the forming operation the assembly is baked at about 350‹ to 375‹ F. for about 4 to 5 hours to effect the bonding. The shrinkage of the low friction material 7 provides sufficient freedom of motion of the inner bearing member to provide an operable bearing. Instead of relying on the shrinkage accurate clearance is obtained by inserting an expansion pin 8 or 8<SP>1</SP> into the inner bearing member prior to the forming operation and removing it afterwards whereupon the inner bearing member returns to its original size and provides the required clearance. Specification 919,224 is referred to.

[Class 59] Fluid under pressure is injected into a pulverizing chamber to rotate and pulverize a mass of material therein, the fine material being classified by the action of centrifugal force opposing the force exerted on the material by the pressure fluid as it escapes towards a co-axially disposed outlet. As shown the steam &c. jets 14 are mounted on a conduit 6 adjustable vertically into holes 24 or 241 by discs 12 on a screwed rod 13 bearing on the ends of screwed rods 8 which support the conduit. The holes 24 in the attrition ring 23 for the nozzles 14 are Venturi-shaped and are inclined so that the jets are tangential to a circular path 30. A collector 25 extends upwardly through the centre of the ring 23 and is surrounded by a false bottom 16 adjustable by screwed discs 21. The ring 23 is enclosed by a casing 1 and has an outlet 31 for the dustless gaseous fluid and an hopper 34 for the material to be ground which is forced into the chamber 29 by a jet 35. A flange 38 on the collector 25 retards the flow of large pieces of material into the collector. Material within the ring 23 is forced to revolve in a path A by the jets 14 and ground against the serrated sides of the ring and against the particles contained therein. The heavy particles are centrifuged towards the serrations whilst the fine material flows over the top of the collector 25 and due to its whirling motion descends down the sides whilst the dustless gaseous fluid leaves at 31. Some of the heavy particles overflow the ring 23 into the chamber 39 and when they reach the level of the jets 14 are blown into the ring 23 so that the feeder 35 may if desired discharge into the chamber 39. The fineness of grinding may be varied according to the feed and height of false bottom 16. The ring 23 may be dispensed with and the casing may have various shapes. The conduits 6 may be in pairs the jets being inclined toward one another to produce a rotary motion of the material, they may also project onto a flat surface. The jets may be arranged spirally to produce a cylindrical blast.

Abstract: 1412053 Data processors WESTINGHOUSE ELECTRIC CORP 11 July 1973 [31 July 1972] 33015/73 Heading G4A A programmable digital data processor operates in fixed point arithmetic and generates an overflow signal whenever an arithmetic operation results in a number which is greater than the largest number that can be represented by a word in the number representation employed. When such a number occurs the result of the arithmetic operation is set to the said largest number. The number of times that an overflow signal occurs is counted, and if the count becomes excessive a scaling factor is applied to the data operated on by the processor. The processor (Fig. 1, not shown) comprises a control unit (10), an arithmetic unit (11), and memory unit (12). Under control of instructions from a program memory (13) and a microprogram memory (15) the control unit controls the arithmetic and memory units. The memory unit comprises a number of memory modules (21). The overflow signals are counted (30) and scaling signals stored (31). A number of such processors can be connected serially and controlled by a common controller. The arithmetic unit 11, Fig. 5, comprises four multipliers 60-63 and six adders 64-69. It is designed to simplify the operation of the fast fourier transform.
