Title: Heating apparatus
Inventor: PORTER ERNEST HENRY ROBERTS
IPC: A47J37/04
Filed: 1970-01-13
Abstract: 1283864 Endless conveyers E H R PORTER and D L M PORTER 13 Jan 1970 [22 Jan 1969] 1649/70 Heading B8A [Also in Divisions A4 and H5] Heating apparatus, particularly for toasting slices of bread, but applicable to cooking meat or other items of food, includes a conveyer 18 with a plurality of mounting means or frames 26 fixed to it and extending away from it to hold individual items (slices of bread) to be heated in a substantially vertical plane away from the conveyer surface, the items passing between two horizontally elongated substantially vertical heat sources 10, 12, e.g. infra-red electrical heating elements 10a, 10b, 10c and 12a, 12b, 12c. Heating may be by microwave energy, or by gas flames, or jets of hot gas or steam. The conveyer is a roller chain or belt or cable moving over sprockets 20a, 20b, 20c, 20d or pulleys in a greaseway 24, and is heat resistant, e.g. consisting of one or more endless stainless steel cables. The toaster frames 26, Figs. 4-6 (not shown), protect the leading and trailing edges of the bread from burning, and the side supports 34 comprise coil springs or thin steel wires which leave a diagonal cutting line across the toast. Two conveyers 18.1, 18.2, Fig. 8 (not shown), may pass between three heat sourcee 10, 11, 12. The electric heating elements are individually adjustable to different temperatures, and the distance apart of the heat sources may be varied. Reflectors 14, 16 direct the heat towards the items to be heated. Conveyer 18 may travel through a heated oil bath in deep frying apparatus. Hot air is directed between the heat sources, either by impellers (not shown) or convection, and emerges from the casing surrounding the heat sources so as to warm items on warming shelves 72 or 70. The air flow is said to disturb and remove the "curtain" of steam forming between the bread being toasted and the heating elements. The apparatus has visual signal lights to indicate when the heating elements are switched on and a regulation knob for adjusting their temperature and/or position. The conveyer(s) 18 may be driven at a constant speed or by a motor including a stationary phase while food is between the heating means.

Title: Improvements relating to Graft Copolymers
IPC: C08G73/02
Filed: 1968-01-11
Abstract: 1,164,582. Polyalkylene imine-polycarbonamide graft copolymer. ALLIED CHEMICAL CORP. 11 Jan., 1968 [11 Jan., 1967], No. 1717/68. Heading C3R. A graft copolymer comprises a linear polyalkyleneimine backbone with polycarbonamide side chains pendant from some or all of the imino nitrogen atoms. The polyimine should have no more than 5 chain carbon atoms between the nitrogen atoms, and the repeating unit of the carbonamide may have 3 to 18 atoms between the amido nitrogen atom and carbonyl group; the side chains having a number average molecular weight of at least 500 but not greater than half the average molecular weight of the polyimine. The backbone polymer is preferably a polyethyleneimine of molecular weight at least 20,000 and up to 500,000; substituted ethylene imines may also be used. The grafting may be effected by polymerizing a lactam in admixture with the polyimine using an acidic catalyst, or by preforming the polycarbonamide and heating with the polyimine in the presence of a strong acid, e.g. an acid of phosphorus. The latter method may be used with N-acyl polyimines obtained by polymerizing oxazolines. The copolymers may be modified by reacting the amino end groups with, for example, carboxyl groups, or with difunctional compounds such as diisocyanates to give cross-linking. They may be mixed with additives, e.g. titanium dioxide, 2,9-dimethyl quinacridone pigment, manganese compound/ hypophosphorous acid light stabilizer, copper compound/phosphorus compound/halogen compound heat stabilizer, glass fibres, carbon black, molybdenum disulphide, flame retardants and other polymeric materials such as polyethylene, PTFE, PVC, polyethylene terephthalate and polycarbonamides. The copolymers alone or as blends with fibre-forming polymers may be drawn into oriented filaments.

Title: Brake control mechanism
IPC: B60T11/10
Filed: 1936-01-20
Abstract: 472,628. Controlling motor vehicles. DEHN, F. B. (Wagner Electric Corporation) Jan. 20, 1936, No. 1812. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 14, 1936.] [Class 79 (v)] [Also in Group XXXIV] Release -preventing means for motor vehicle brakes comprises a ball movable by gravity and by inertia so as to be effective to prevent release of the brakes when applied with the vehicle at rest on the level or on an upgrade, but ineffective when the vehicle is being decelerated. The device may also be rendered ineffective when the clutch is disengaged. A hydraulic brake system is shown in which pipes 4, 6 leading from the master cylinder 1 to the brakes are connected to a casing 10 having a track 25 for a ball-valve 24 which is positively held off its seat when the clutch is engaged, by a stem 31 engaged by a cam 35 connected by arm 14 and link 16 to the clutch pedal 15. The casing 10 is pivotally mounted in a bracket 36 on the vehicle frame member 8 so that it can be set with the track 25 at a slight inclination upwardly and forwardly. When the clutch is disengaged the parts 14, 35, 31 are in the position shown in full lines, Fig. 2, and if the vehicle is at rest on the level or an upgrade the valve 24 will seat, thus preventing return of the liquid from the brakes to the master cylinder after the brakes have been applied by the pedal 2 by which the master cylinder is operated. If, however, the brakes are applied when the vehicle is travelling forwardly, the ball-valve 24 due to its inertia and the retardation of the vehicle will move away from its seat thus permitting release of the brakes in the ordinary way upon return of the brake pedal. In a modification, the ball is contained in a cage slidable within the casing 10 by a cam such as 35. The casing is, in this case shown mounted on the end of the master cylinder, a pivotal connection being provided to permit adjustment of the inclination of the ball-track of the cage.

Title: Improvements in or relating to brakes for aircraft wheels
IPC: B64C25/48
Filed: 1936-01-23
Abstract: 469,407. Aircraft wheel brakes. INDIA RUBBER, GUTTA PERCHA, & TELEGRAPH WORKS CO., Ltd., and TARRIS, F. J. Jan. 23, 1936, No. 2225. [Class 4] In a brake for aircraft having a main control device 7, Fig. 3, for simultaneously applying the brakes on the two sides of the aircraft and two auxiliary control devices, Fig. 4, for differentially controlling these brakes, each auxiliary control device comprises a plunger 32 moved by fluid from the main control device and which moves as an integral unit with an element 33 which controls and is co-extensive with the brake releasing valve or plunger 29. The main control device 7 includes an exhaust valve comprising a piston 13 carrying a rubber washer 42 seating at 14, the piston having a projection 18 for engaging the stem of a supply valve 11 controlling the connection of a compressed air reservoir with a chamber 12 through pipe 6. Yielding of the washer 42 enables the piston and projection 18 to move after closing the exhaust, to open the valve 11. The piston 13 is operated by a cable 10 through a bellcrank 8 pivoted at 9, a sliding element 17 and a spring 15. The auxiliary devices 19, 20 each comprise valves 28, 29 similar to the valves 11, 13 operated by the plunger 32 through the extension 33 and spring 34. The plunger 32 forms with a rubber sleeve 35 a variable volume chamber connected to the chamber 12 of the main device by passages 24, 21. Chamber 12 is connected also by passages 23, 25 to chambers 281 of the auxiliary devices. When the main device is operated by the cable 10 compressed air supplied to the chamber 12 flows to the chamber 35 moving the plunger 32 against the action of spring 36, to close valve 29 and open valve 28, thus supplying the corresponding brake through pipe 30 until the pressure therein overcomes the loading of the spring 34, the member 29 then moving back sufficiently to permit the valve 28 to close while itself remaining seated. A member forming in effect a T-shaped lever pivoted at 39 has an arm 40 connected to the rudder bar and arms 38 with which parts 37 secured to the plungers 32 contact when the brakes are applied. Operation of the rudder bar thus moves back one or other of the plungers and effects a partial or complete release of one of the brakes. Specifications 397,497 and 415,097 are referred to. The Provisional Specification describes a hydraulic arrangement.

Abstract: 963,962. Fuelling reactors. COMMUNAUTE EUROPEENNE DE L'ENERGIE ATOMIQUE (EURATOM). Jan 21, 1963 [Jan. 23, 1962], No. 2535/63. Heading G6C. The manipulator arm of Specification 963,961 comprising two chain-like assemblies which are fed out from individual coils to interlock with one another and form a rigid arm, is mounted on a support enabling the arm to have universal movement about a plurality of axes. As shown, the two chain-like assemblies are coiled in their retracted condition in respective casings 18, 18<SP>1</SP> of a chain extension-retraction unit A mounted on the upper end of a tubular pedestal member B. The member B is mounted for rotation within a sleeve C itself mounted for rotation about a horizontal shaft 86 supported by a frame D, the latter being rotatable about a vertical axis on a platform E. The coiled chain-like assemblies are guided by spirally arranged guideways 52 within the casings 18, 18<SP>1</SP> and are extended or retracted by two driven shafts 12, 12<SP>1</SP> each shaft driving a pair of Geneva cross gears 8, 10 engaging the link members of a respective chain-like assembly. Link members of the two assemblies are shown at 14, 16. The shafts 12, 12<SP>1</SP> are driven in synchronism by a motor gear unit 40, 41 and the interlocked assemblies forming the rigid arm are guided by rollers (Fig. 4, not shown) within the pedestal member B so that the arm may be extended along the axis of the member B, the end of the arm carrying a tool 150 for handling fuel elements in the channels of a reactor. The normally vertical axis of the member B and sleeve C is laterally displaced from the axis of rotation of the frame D on the platform E and hence the sleeve C is coupled to the shaft 86 through an eccentric annular plate 77 whereby when the structure A, B, C is tilted out of the vertical by rotation of the shaft 86 and the frame D is rotated, the manipulator arm describes a cone about the vertical axis of the frame. The platform E may be carried by a gantry crane (Fig. 3, not shown) for horizontal movements in two directions mutually at right angles.
