Title: Improvements in or relating to fluid pumps
IPC: F04B43/12
Filed: 1965-03-26
Abstract: 1,067,529. Flexible - tube pumps. B.H. REFSON. Jan.26, 1966 [March 26, 1965], No.12927/65. Heading F1F. A fluid pump comprises a flexible tubular member 14, Fig. 1, of e.g., silicone rubber anchored at its ends and a rotary member 11 having a plurality of radial projections at circumferentially spaced intervals around its periphery with a portion of the tubular member tautly disposed around the rotary member. As shown, the rotary member 11 made from material having a low coefficient of friction, e.g. PTFE, has three projections defining three concave sides 12 joined by small raduized convex corners 13, 13a, 13b against which the tubular member is flattened to occlude the tube. The rotary member may be lengthened to permit of the use of two or more tubes carrying separate fluids. Since the corners 13, 13a, 13b, are too small to permit the fitting of rollers, it is desirable to fit an absorbent pad 27 soaked at intervals with glycerine and water to lubricate the tube to assist the movement of the tube over the corners. In another embodiment, the tube may be stretched over the rotary member in a substantially U-shaped formation.

Title: Improvements in and relating to mechanical toys
IPC: A63H30/04
Filed: 1955-05-04
Abstract: 786,977. Mechanical toys. HEIDECKER, H. H. G., HEIDECKER, H., and HEIDECKER, E. BERNHEIM-, [trading as KEIM & CO.]. May 4, 1955 '[Nov. 22, 1954], No. 12958/55. Class 132(3) A mechanically driven toy, e.g. a toy vehicle, has a microphone for controlling the starting and stopping of the driving motor and for controlling other mechanism such as steering means. A toy vehicle contains a microphone and an amplifier for operating an electromagnet 7 of which the core 8 co-acts with a pivoted armature plate 10 having projecting portions 24, 25. The outer portion 24 is shorter than the inner one and normally engages an upwardly turned member 23 of a plate 20 having an aperture 19 and pivoted at 22 to a frame 21 of a clockwork mechanism 4. The end of a cranked spindle 18 engages the edge of the aperture 19 and an arm 26 carrying a pin 27 is rotatable by a spindle 16, the pin engaging the edge of a rectangular aperture 28 formed in a plate 29 secured by vertical rods 30, 31 to pivoted front axle assemblies. The arm 26 also actuates a contact spring 32 for controlling current supply from a battery to an electric motor 5 for propelling the vehicle. Tension springs 33, 34 normally maintain the front wheels in a straight ahead position. With the spring 11 of the clockwork mechanism wound, when the microphone picks up a suitable sound, the plate 10 is momentarily attracted to the core 8 and the cranked spindle 18 is allowed to revolve once as the member 23 of the plate 20 is freed by plate portion 24, the arm 26 turning through 45 degrees (position (2) Fig. 1) and causing the motor 5 to be switched in circuit by the contact 32. The next sound impulse acting on the microphone causes the arm 26 to turn through a further 45 degrees to position 3, the plate 29 and the front wheels being moved to the right from the position shown. With the arm in position (4), the wheels are allowed to move to "straight ahead," and in position (5), the motor 5 is switched off. A similar sequence of operations results from the arm turning through a further 180 degrees the front wheels in this case turning to the left. The vehicle may be clockwork propelled and may run on rails in which event on-off and forward-reverse control is provided.

Abstract: 890,963. Reciprocating pumps. SUTCLIFFE Ltd., RICHARD, and BAINES, L. April 19, 1960 [April 16, 1959], No. 13040/59. Class 102(1). [Also in Group XXIX] A pump for use in a hydraulic system (Group XXIX) in a nione comprises a plurality of pistons 10 reciprocable in cylinders 11 by cams 19 on shafts 21, 22, shaft 21 being driven by a motor and connected by epicyclic gearing 25 to the shaft 22. The epicyclic gearing has a carrier movable by a servo-motor to adjust the phase relation between the pistons driven by the shafts. The pistons are connected to chambers 12 having inlet valves 13 and outlet valves 14 leading to a common outlet 17. When the gearing is adjusted so that the pistons reciprocate in phase, they draw liquid through the valves 13 into the chambers 12 for discharge through the valves 14 and outlet 17. When the pistons reciprocate in antiphase, the output of the pump is reduced to zero, liquid displaced from the cylinders associated with one shaft being circulated to the cylinders associated with the other shaft and vice versa.

Abstract: 1,002,794. Casting rods. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 31, 1964 [April 4, 1963], No. 13226/64. Heading B5A. [Also in Division B3] In a method of casting, particularly uranium carbide, uranium dicarbide, thorium dicarbide and alumina, granular material is melted in a mould in such a manner as to leave along the wall of the mould a layer of unmelted grains forming a protective cushion during cooling. The layer is subsequently removed from the casting. Particulate material is supplied to a continuous casting mould 1 by way of an electrically vibrated plate 21 and is melted by an electron beam 11, the apparatus being enclosed in a container 12 having a rarefied argon atmosphere. The coating is withdrawn by a starter bar 6. The mould may be vibrated by electromagnetic means 30 and the particulate layer 15 removed by machining. Shapes such as tubes may be made, the incomplete melting being achieved by relative movement of the mould and the heat source.
Patent GB-132434-A (GB)
IPC: G01S3/06
Abstract: 132,434. Bellescize, H. J. J. M. de R. June 26, 1917, [Convention date]. Wireless telegraphy.-Relates to arrangements of receiving-circuits in which complete symmetry is obtained in order to minimize disturbances due to atmospherics, variations of earth potential, neighbouring transmitters, &c. Owing to the unsymmetrical arrangement of the detector and telephone in relation to the rest of the receiving- circuit, the capacity of these instruments with respect to earth, or the remainder of the circuit, produces effects which may be represented by superposing upon the main oscillation circuit the oscillations of a second imaginary open oscillation circuit, which is susceptible of being rendered oscillatory directly through the ground. The oscillations produced in this second circuit reduce syntony or render inaccurate the determination of direction by radio-gonometric methods. The disturbances are removed by making the circuit as symmetrical as possible with respect to the earth. In the arrangement shown in Fig. 1, in which the main oscillation circuit CL is connected to a valve detector f, g, p and telephone T<1>, additional capacities, resistances, and inductances are connected to one lead b to balance the effects due to the operator and telephone T<1> connected to the other lead a. As shown, a condenser C<11> and telephone T<11> balance the condenser T' and telephone T<1>, a condenser C<3> represents the capacity of the operator with respect to her telephone head-gear &c., a condenser C<4> and resistance R<1> represent the operator, a condenser C<5> balances the effect of the capacity between the grid and filament of the valve, and a condenser C<1> balances the capacity of the constituent parts of the detector. The effect of the operator may be reduced by connecting her telephone through inductances to the secondary of a transformer, the primary of which is in the plate circuit, or by the use of a microphonic relay. The arrangement may be used in connexion with a Faraday's cage. In the arrangement shown in Fig. 2, the oscillation circuit LC is coupled to the detector circuit L<1>C<1> by two coils a, b, arranged symmetrically with respect to the capacity C and wound so that the induction effects between aL<1> and bL<1> will assist each other when produced by currents flowing round the loop LC, but will cancel each other when produced by currents flowing in opposite directions in the coils a, b to earth or to the coil L<1>.

Title: Electric ignition and control system for burners
Inventor: WILLSON JAMES ROBERT
IPC: F23Q7/12
Filed: 1970-03-19
Abstract: 1293202 Controlling burners; igniting burners ROBERTSHAW CONTROLS CO 19 March 1970 [20 March 1969] 13288/70 Headings F4F and F4T An electric ignition and control system for a fuel burner comprises an electric igniter 10 with a positive temperature coefficient of resistance in series with a relay 12, ballast resistor 14 and switch 16, and an electrically operated fuel valve 20, switch 22, and relay contacts 24 in parallel with the igniter 10. When switch 16 is open, contacts 24 are open, but when switches 16 and 22 are closed then relay 12 is energized and contacts 24 closed, current flowing through and heating igniter 10 thereby increasing its resistance and thus the voltage applied across the valve 20. Only after the igniter has reached a sufficient temperature to ignite the fuel is the voltage applied to the valve sufficient to turn it on. The relay 12 may also be current-sensitive. In a modification (Fig. 2, not shown) a hot-wire ballast relay (30) serves as a current-sensing means, and a P.T.C. thermistor is (32) used as a flame sensor since when connected in series with the igniter it will reduce the voltage drop across the igniter to a value insufficient to maintain the valve open unless the igniter is heated by a burner flame.

Title: Improvements in or relating to the manufacture of cellulose derivatives
IPC: C08B11/04
Filed: 1920-05-13
Abstract: Cellulose derivatives suitable for the same or similar applications to the known cellulose ethers and esters, are prepared by reacting on cellulose or its conversion products with halogen esters of glycols or of polyhydric alcohols, or of their ethers, for example, ethylene or propylene chloride or chlorhydrin, glyceryl chlorhydrins, epichlorhydrin, and monochlorether; if the esters contains free hydroxyl groups, then such groups are retained in the resulting cellulose derivative. The reaction is carried out in the presence of basic substances, preferably caustic alkalies, and it is preferred to start with cellulose or a conversion product not soluble in alkali and as little depolymerized as possible; it is preferred to employ in the reaction limited quantities of water, say from no water up to four times the weight of the cellulose taken but preferably between one half to one and a half times such weight, and preferably a total amount of alkali as would correspond to a 50-75 per cent or even 95 per cent solution in the water present or added; usually the reaction is carried out at about ordinary temperature, and preferably with cooling to about 0 DEG  C. or lower, and the reaction may be carried out with the additional of diluents or solvents such as benzol, and in the presence of contact substances such as copper powder, or copper salts or hydroxides.  In examples, cellulose is impregnated with 50 per cent caustic soda solution, kneaded with ethylene chlorhydrin or glyceryl mono-chlorhydrin while cooling to 0 DEG  C., with subsequent additions of powdered caustic soda and chlorhydrin; alternatively, the cellulose may be impregnated with water and the caustic soda added in powdered form.  The whole of the caustic alkali may be added prior to the treatment with halogen ester, and the ester may be incorporated all at once or in portions or continuously during the process.  Mixed cellulose derivatives may be obtained by the introduction of different groups or residues of the class referred to, or by the introduction of other ether groups such as alkyl groups and according to the process of Specification 164,374, benzyl and homologous groups and according to the process of Specification 164,375.
