Filed: 1938-02-01
Abstract: 492,953. Wood - block flooring. BUCKLEY, J. F. Feb. 1, 1938, No. 3088. [Classes 20 (iv) and 87 (i)] A method of laying wood blocks consists in attaching the blocks to the base by a film 5 of bituminous adhesive, some or all of the blocks being laid at spaced distances so as to form channels between them, then brushing into these channels semi-dry hydraulic cement until they are full to about half their depth, thereupon filling the upper portions of these channels with hydraulic cement in a normally wet state. The hydraulic cement may consist of magnesium chloride, magnesium oxide, and wood flour. Dovetail rebates 2 are provided along the lower edges of the blocks to accommodate any of the bituminous adhesive which is squeezed out during the laying of the blocks. A continuous horizontal slot 3 extends around the sides and ends of each block in order to provide a key for the hydraulic cement inserted in the channels between the blocks. These channels are provided, during laying of the blocks, by temporarily laying distance pieces between adjacent blocks. After the floor lias been laid, the top surface of the blocks and the hydraulic cement inlays are sandpapered. and polished. Where the pattern is such that adjacent blocks are in abutment, these blocks may have a wood strip engaging co-operating slots 3.

IPC: G11C11/14
Filed: 1960-01-28
Abstract: 975,016. Digital data storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 17, 1961 [Jan. 28,1960], No. 3096/60. Heading G4C. [Also in Divisions H1 and H3] Non-destructive readout of a binary data bit stored in magnetic thin film with an easy axis is effected by use of an oscillator to "wobble" the direction of magnetisation about that axis, and a detector including a phase discriminator magnetically coupled to the thin film, the non-linearities of the coupling between oscillator and detector enabling the discriminator to produce a signal dependent on the sense of magnetisation. As shown a thin film element 1 with easy axis 2 is magnetised in one sense or the other by first energizing line 10 with driver 4 to produce a field at right angles to axis 2, then superimposing a field parallel to 2 with driver 5 or 6, switching off 4 and then 5 or 6. For reading, two oscillators 12, 13 feed signals to line 10 and the beat frequency is produced in line 17 with a phase dependent on the bit stored; this is detected at 20. In a modification the phase detection of a harmonic of a single oscillator is utilized.

Abstract: 939,887. Thermal switches. KING-SEELEY THERMOS CO. Jan. 30, 1962, No. 3406/62. Class 38 (5). [Also in Group XXXV] The controller for an oven 10 comprises a casing 96 in which are housed a number of polymetallic elements all of which are ambient temperature compensated by virtue of their shapes and all of which have heating coils associated therewith. The polymetallic element 36 is of the self-interrupting type and forms a voltage regulator whilst the polymetallic elements 156, 182 co-operate with one another and form a heat regulator for the oven 10. Current passing through a heater coil 174 of the element 156 causes the leg 154 to bend so that a pin 152 attached thereto moves a disc 142 in an anti-clockwise direction. The disc 142, which carries a contact 148, is attached to a spindle 134 journalled in a nylon bearing 118, a pointer 140 being fixed to the spindle 134 outside the housing 96. A bracket 122 which is a push fit on the bearing 118 carries the polymetallic element 182 which itself carries a contact 178. The contacts 178, 148 are in the circuit of the heating current for the element 182 so that incipient opening and closing of the contacts occurs. A second manually adjustable pointer 104 is carried on a spindle 106 journalled in a bracket 100 fixed to the housing 96, the pointer 104 having a part 110 bent at right-angles which co-operates with a slot 112 in the bearing 118. Movement of the pointer 104 thus causes movement of the bearing 118 and hence the bracket 122 whereby the polymetallic element 182 is moved to set the position of the contact 178. All of the thermally operated members are initially settable by means of rack- and-pinion devices.
