Title: Hinge assembly for a swingable door
IPC: E05F1/06
Filed: 1964-02-05
Abstract: 1,003,939. Swingable door hinges; doors. ELIASON REFRIGERATOR CO. Feb. 5, 1964 [Feb. 17, 1963], No. 4986/64. Headings E1J, E2F and E2M. A hinge for a self-closing double swing door comprises upper and lower hinges 10, 11 lying on a tilting axis 50 so that the door tends to return to the closed position, the one hinge 10 having a hinge pin 42 with diametrically opposed support members such as rollers 46, 47, the pin 42 extending through an opening in a plate 63 which is formed with a groove 73 adapted to receive the rollers 46, 47 so as to locate and return the door to the closed position. As shown in Figs. 3, 6 the pin 42 is secured to the door and the plate 63 to the door frame but in other embodiments the arrangement is reversed and the plate is then formed with a downwardly opening groove, e.g. as shown in Fig. 9. The other hinge means comprises a pin 83 secured to the door frame and is slidably and rotationally pivoted in the guide member 79 secured to the door. In addition whilst the axis of the hinge pin 42, 83, Fig. 3, may lie on the tilting axis, in the arrangement shown in Fig. 9 the hinge axes are parallel to the door but offset. The rollers 46, 47 which may be of nylon or hardened steel may also be in the form of roller or ball-bearings. When the door is opened, due to the camming action of the rollers 46, 47 along the side walls of the groove 73, the door rises. On closing the door the swinging movement is quickly damped by the action of the rollers 46, 47 within the groove 73. The doors 12 may be fabricated from lightweight material, e.g. wood or aluminium, and reinforced by a more durable surface over the upper portion and by a panel 20 of a heavier metal over the lower portion, where rougher treatment would be expected. The added weight of the lower panel 20 facilitates the closing movement of the door. Vertical door seals and bottom seals 96 made of resiliently flexible material, e.g. reinforced rubber or plastic material, are provided.

Abstract: 868,357. Comparison systems. PERKINELMER CORPORATION. Feb. 12, 1960 [Feb. 19, 1959], No. 5088/60. Class 97(1) A radiation comparison system has part of the optical path for the sample beam extending from a focus of an ellipsoid to a reflector on the surface of said ellipsoid and from there to the second focus at which the object may be placed; the path then continues to a second elliptical reflector having at least the same second focus as the first, both reflectors being arranged so that they are not intersected by either major axis. In the system shown a reference beam of radiation 10 and a sample beam 12 are emitted from a source 14 and enter a monochromator housing 16. Before beam 12 enters said housing it is reflected by a plane mirror 18 and focused on to a second plane mirror 20 placed at a focus of an ellipsoid 22 on the surface of which two mirrors 24, 28 are placed. The light passes from mirror 20 via mirror 24 to the second focus of the ellipsoid, at which a sample 26 is placed, and from there to mirror 28. It is then reflected by a second reflecting surface on mirror 18 to the housing 16.

Title: Improvements in and relating to filter systems for clothes washing machines
IPC: D06F1/08
Filed: 1948-02-20
Abstract: 652,169. Washing machines. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 20, 1948, No. 5102. Convention date, Feb. 24, 1947. [Class 138 (ii)] A clothes washing machine comprises a tub 1 containing a spin basket 4 having walls forming an overflow passage 10 to determine the liquid level, has an annular trough 25 in the upper end of the basket 4 with a screen 24 in its bottom wall supported in the receptacle so that the screen is below the normal liquid level in the receptacle during washing and on to which liquid circulated from the tub by a pump 20 is discharged from a nozzle 23 angularly arranged so as to discharge in the direction of rotation of the spin basket. With this arrangement the agitation of the water during washing keeps lint and other foreign matter from settling on the filter and so increases the time before it becomes clogged. The clothes receptacle comprises a tub 4, the walls of which are corrugated and which is carried in a balancing ring 6. The tub 4 is spaced from the balancing ring 6 by members 11 to provide water channels 10 to an opening 13 in the base of the balancing ring and both the tub 4 and the ring 6 are attached to a shaft 8 which is stationary during washing and which is rotated for spin drying. The tub assembly is resiliently supported by compression springs 16. An agitator 5 is oscillated by a shaft 14 which is mounted inside shaft 8 and this agitator has a screened discharge opening 26 at its upper end which opens into a channel, between the agitator and the shaft 8, which leads to the opening 13 in the balancing ring. Water from the discharge opening 13 and passage 10 is returned by a pump 20 to the nozzle 23 which is positioned at an angle so that during a flushing operation in which the tub is rotated, water leaving the nozzle moves backwards relatively to the filter and serves to strip lint and the like from the filter. Specification 625,324 is referred to.

Title: Brake control system
IPC: B60T8/1761
Filed: 1975-02-07
Abstract: 1472388 Aritiskid braking systems NISSAN MOTOR CO Ltd 7 Feb 1975 [8 Feb 1974 3 April 1974] 5267/75 Heading F2F In a method of controlling a brake of a vehicle having a manually operated brake and means for controlling the application braking pressure the speed of the vehicle is sensed and a first signal is produced having a frequency proportional to that speed, the circumferential speed of the wheel is sensed and a second signal having a frequency proportional to that speed produced, the frequency of the first signal is counted and a disabling signal is produced, when a first predetermined number is counted, and applied to the pressure control means to interrupt the application of pressure, the frequency of the second signal is counted for producing an enabling signal when a second predetermined number is counted and the signal is applied to the control means to apply braking pressure and the occurrence of the disabling signal and enabling signals are inhibited by the enabling and disabling signals respectively. The ratio of the first and second predetermined numbers is so chosen that the rate of wheel slip approaches the optimum of 10-20% when the brake is operated. A vehicle speed sensor 10 such as a conventional Doppler radar apparatus supplies pulses to a counter 12 and a wheel speed sensor supplies pulses to a counter 13 the outputs of the counters being so connected that the contents of each counter are cleared by the output of the other and they are connected to a flipflop 14 so that counter 12 sets it while counter 13 resets it. A signal from counter 12 sets the flipflop 14 and a high level signal appears at its Q output to be amplified by an amplifier 15 and applied to an actuator 16 which controls braking pressure to release the brake. If on the other hand the slip rate is smaller than the optimum a signal will be produced by counter 13 to reset flip-flop 14, de-energize actuator 16 and reapply the brake. In another embodiment Fig. 2 the system includes a frequency to voltage converter 30, a differentiator circuit 31, a comparator 32 and a second comparator 33 the outputs of which are applied to the counters via AND gates 34, 35.

Patent GB-963943-A (GB)
Title: Clear,transparent alkenyl aromatic copolymer compositions
IPC: C08L35/06
Filed: 1961-05-26
Abstract: The Specification claims clear transparent copolymers comprising at least 80 mole per cent of a vinyl or isopropenyl aromatic compound and up to 20 mole per cent of a "monohydric" primary or secondary alcohol partial ester of an ethylenically unsaturated di- or tri-carboxylic acid.  The term "monohydric" alcohol embraces polyhydric alcohols which have been partially etherified to leave a single free hydroxyl group. According to one process claim they may be prepared by addition of the polymerisable mixture to a polymerisation system containing up to 50% wt. of a specified solvent and continuously withdrawing a portion of the polymerising mix at substantially the same rate as monomer and solvent are added.  The specified solvents have a boiling point between 50 DEG  and 225 DEG C., contain up to 8 carbon atoms, and are aliphatic, cycloaliphatic or aromatic ketones or ethers, the latter having an O:C ratio of at least 1:4.  According to another process claim specific to maleate esters a solution of 95 to 65% wt. of the partial ester plus catalyst is added to a solution of 5 to 35% wt. of the partial ester, all the aromatic monomer and further catalyst at a constant rate such that addition is completed at 70 to 85% conversion. Optional termonomers which may be used in minor proportions are acrylonitrile, methacrylonitrile, alkyl acrylates and methacrylates and dialkyl maleates and fumarates having up to 8 carbons in the alkyl group(s). The copolymers may be used in the coating and laminating compositions described in the Specification 963,942. In addition aqueous solutions and dispersions may be obtained by forming a salt of the free carboxyl group with sodium, potassium or lithium hydroxide or preferably a nitrogenous base such as ammonia, hydrazine, primary secondary or tertiary amines or substituted hydrozines.  The salts may be used as emulsifying or suspending agents, e.g. if a xylene solution of its copolymer is neutralised with aqueous ammonia the salt is extracted into the aqueous phase leaving a stable xylene in water emulsion. The higher polyalkylene oxy monoether half ester polymers and their amine salts are thermosetting in cast film form. Specification 715,666 also is referred to.

Abstract: 491,211. Interrupters. ELECTROFLO METERS CO., Ltd., and HOATHER, W. H. Feb. 24, 1937, No. 5528. [Class 38 (v)] [Also in Group XXXV] Two or more cyclically operable electric switches each co-operate with a rotary member so that the ratio of operative and inoperative periods of each depend upon the position of the switch in relation to the rotary member. Means for producing relative longitudinal movement between the rotary member and one or more of the switches is provided. Fig. 3 shows switches A, B on carriages, which may be coupled, as by a spring, to move together along a screw 16 ; abutments 24 engage the surface of a cylindrical cam 14 driven at a constant and preferably slow speed so that the switches are closed for periods depending on the position of their carriages and open for the remaining period of each cam cycle. An adjustable stop 22 may determine the limit of movement of the switch B along the cam. The switches A, B may control the operation of a furnace and a reversible driving device such as an electric motor may rotate the screw 16 in one direction when temperature is high and the other when it is low with an intermediate range of temperature in which it is at rest. Switches C and D operated by the cam may be inverted in the respective motor circuits to produce different average speeds of the motor in different directions. Fig. 2 shows suitable circuit connections for the control of means F<1> controlling heating apparatus in accordance with a temperature sensitive selector operating upon switches E, F, G, and in which three cam operated switches A, B, J having different " on "-" off " ratios are employed. When temperature is low switches F and G are closed and the furnace is controlled by the switch J which has the longest closure period. When temperature is normal the switches F and G are open and the contacts d, e closed so that switch A is in control. In high temperature conditions the contacts d and c are closed and the switch B is in series with switch A to produce a minimum closure time. The motor M is operative as described above to vary the " on "-" off " ratio of the switches during high and low conditions only. If different speeds of the motor are not required a manually adjustable switch K may replace the switches C, D. The cam 14 is preferably exponentially shaped but any shape desired may be used. The screw may have a varying pitch. The switches may be constituted as brushes engaging a rotary member having suitably shaped conducting and insulating portions.
