Title: Improvements in and relating to masonry units
Inventor: ABBEY ARTHUR
IPC: C04B41/63
Filed: 1956-02-21
Abstract: A masonry construction unit such as a cinder, slag, cement or concrete block, clay brick or unglazed tile is coated on at least one surface with a polyester resin and a filler, e.g. sand or diatomaceous earth, to which is bonded a fibrous mat, e.g. a mat of glass fibre, asbestos fibre, woven glass cloth, cotton, wool or paper, followed by a further coating of polyester resin, which may penetrate the mat and unite with the first layer.  The resins used may be prepared by reacting a polyhydric alcohol such as ethylene glycol, diethylene glycol or propylene glycol with unsaturated dicarboxylic acids such as maleic or fumaric acid. Catalysts such as benzoyl peroxide or a mixture of 60 per cent methylethyl ketone peroxide and 40 per cent dimethyl phthalate, and accelerators such as cobalt naphthenate or stannous chloride may also be used.  The resins are cured at a temperature not above 280 DEG  F.  The final coating may contain a pigment, and a glazed finish may be obtained by applying a smooth impervious sheet, e.g. of "Cellophane" (Registered Trade Mark) or of glass under pressure to the surface during curing, and afterwards peeling it off.  Alternatively a rough finish may be obtained by adding a suitable filler to the final coating and omitting the glazing step.
Patent GB-947579-A (GB)
Title: Improvements in or relating to timers
IPC: H01H43/12
Filed: 1960-02-16
Abstract: 947,579. Time switches. CONTROLS CO. OF AMERICA. Feb. 16, 1960 [June 30, 1959], No. 5407/60. Heading H2B. The starting position of a timer is set by a device comprising a number of pins, one of which can be selectively depressed so as to ride on the surface of a rotatable disc, which has means for engaging the selected pin to stop the disc at the selected starting position. In one form a number of pins 30 are angularly and radially spaced on a plate 32 and one can be selected and depressed to the right, Fig. 4, by a member 34 rotatable about a sleeve 22. The disc 24 has a number of angularly and radiallyspaced holes 28 so that as the disc 24 is manually rotated, the selected pin drops into the corresponding hole and prevents further rotation until a knob is depressed. This moves the disc to the right, clear of the pin 30, and a cam 18 also moves to the right to allow contacts 16 to close to start the timer motor. When the selected cycle has been completed, a tab 26 on the disc 24 will abut against a fixed lug 40 and stop the disc. This lug has a sloping surface, so that if the knob 38 is again rotated, the tab 26 will ride up on the lug moving the disc to the left, thereby opening contacts 16. In a modification, Figs. 9 to 14 (not shown), each pin 30 is associated with a separate operating push-button, the buttons being arranged in two lines of five, one on each side of the spindle 20.

Patent GB-1049332-A (GB)
Title: Fluidised bed reduction of iron oxide
IPC: C21B13/14
Filed: 1964-02-10
Abstract: In a fluidized bed process for the gaseous reduction of iron ore the heat requirement is supplied by recirculating a part of the product through an external burner under such conditions that no re-oxidation of the metal occurs, while the reduction gases are obtained from the cracking of a hydrocarbon fuel, carbon being simultaneously deposited on the product of the reduction. In one embodiment the fuel is introduced into the final reduction zone, so that cracking and reduction to metal take place together; a part of the carbon-coated ore is recirculated through an external burner where it is heated by the combustion of waste gases from the Fe3O4 --> FeO reduction.  The products of this combustion are then used to reduce Fe2O3 --> Fe3O4. In a second embodiment the fuel is introduced, together with oxygen-containing gas, into a bed of reduced metal particles, where cracking occurs.  The gases are then used to reduce ore in separate reducing zones, while a part of the carbon-coated metal particles is sent to an external heater and there heated by partial combustion of the carbon.  Suitable operating conditions are described, and forms of apparatus are indicated schematically.  The produce may be melted in an electric furnace, the evolved gases being used to heat the recirculated fraction of product.

Abstract: 753,011. Reciprocating electric motors. REUTTER, J. L. March 4, 1952 [March 5, 1951], No. 5688/52. Class 35. [Also in Groups XIII and XXVIII] In a reciprocating electromagnetic pump the armature 2 slides in a non-magnetic tube 5 on either side of which are loops 1 of a magnetic circuit, the flux being produced by permanent magnets 6 on either side of the tube and by A.C. fed coils 12. The pistons 51, 52 are arranged on either side of the armature, and in the form shown are arranged to pump in series, i.e. the fluid, e.g. a refrigerating fluid, passes in at tube 40 and is discharged via tube 41 to the highpressure pump, from whence it is driven out at tube 42. The armature is biased towards its middle position by springs 8, and since it is a close fit in the tube 5 and is separated by seals 21 from the pump chambers, the system may be tuned to resonance by adjusting the gas pressure in the end spaces 44 of the tube. This may be done by connecting these end spaces through tubes 61 and a valve 64 to the high- or low-pressure side of the system being pumped. A pipe 45 joining the spaces and having a controlling valve 46 provides another means of adjusting the natural frequency of the system. As the valve closes, the compression increases and so raises the natural frequency and an automatic adjustment may be achieved by connecting the operating coil 48 of the valve in series with the load coil as shown. In a modification, the magnetic circuits 1, 6 may be replaced by two pairs of oppositely disposed horse-shoe magnets.
