Abstract: 849,006. Moulding building elements ; plaster compositions. SUPERLINE STRUCTURAL PRODUCTS (PTY) Ltd. May 28, 1957 [May 28, 1956], No. 16910/57. Classes 22 and 87(2). [Also in Group X] A moulding assembly for forming a building panel comprises a frame 10 having tongues 12 around its inner edges, and a core consisting of cell-forming elements 15 separated by spaces R for forming ribs on the surface of the panel. The core elements are supported by ribs 14 and an outer frame 13 so shaped that the elements 15 are suspended within the frame 10. In a modification, Figs. 2-4 (not shown), the cell-forming elements comprise sheet metal trays with tapering sides, the trays being supported by channel-section ribs. Holes are provided in the frame 10 to receive twine T for reinforcing the ribs of the panel. The twine may be prestressed by attaching it to bars (not shown) spaced from the sides of the mould and supported by screw-threaded means from the mould and by operating the screws to move the bars away from the mould. A board 16 is fitted in the frame 10 and the plaster mix may be poured before or after the core is placed in position. Plaster composition. The plaster mix for the panel consists of small grain exfoliated vermiculite, gypsum and lime in the proportions by volume of 1¢ : 1 : 1/10, mixed with water and a small quantity of chopped horse-hair, sisal, coconut fibre &c.

Patent GB-785560-A (GB)
Title: Improvements in tuner mechanisms for radio receivers
IPC: H03J7/30
Filed: 1955-06-14
Abstract: 785,560. Radio receiving apparatus. GENERAL MOTORS CORPORATION. June 14, 1955 [June 28, 1954], No. 17043/55. Class 40 (5). In a tuning apparatus for radio receivers of the type in which the tuning may be varied continuously and cyclically by means of a driving motor until the receipt of a signal, whereupon the motor drive is stopped, the tuning elements are driven by the motor through a clutch and epicyclic gear train and an alternative manual control is provided which comprises a worm-wheel engaging a planet wheel of the gear train so that manual tuning may be effected when the motor drive is non-operative. Fig. 2 shows a plan view and Fig. 5 shows a sectional side view of part of the receiver. The motor 4 drives the shaft 10 through the friction clutch 6, 8 and hence drives the worm 14 which engages a wormwheel 28 mounted upon a shaft 30 and clutched thereto so as to rotate therewith. Mounted loosely upon shaft 30 is a spur wheel 42; attached to the underside of this is a framework between which and the wheel 42 is journalled a shaft 48 on which are mounted gear wheels 50; 52. The wheel 52 engages with a pinion 40 which is fixed on the shaft 30, which the wheel 50 engages with a wheel 54 which is loosely mounted upon the shaft 30. A manual control knob drives a worm 100 which engages the spur wheel 42. Thus, when the motor 4 is operative the pinion 40 is driven through the rotation of shaft 10, worm 14 and worm-wheel 28 and hence causes the rotation of gear wheels 52 and 50 whereby, since the spur wheel 42 is held fixed by the worm 100, the wheel 54 is caused to rotate. Rotation of the knob 96 similarly causes the wheel 54 to rotate when the motor is stationary; in this case the wheel 42 rotates while the pinion 40 remains fixed. A double-lobed cam, Fig. 4 (not shown), mounted upon the wheel 54 engages a cam-follower 74 which it draws downwardly (as shown in Fig. 2) twice per revolution of the wheel 54. The cam-follower 74 is attached to a carriage 70 which moves against the action of a spring 76 to vary the tuning of the coils 58, 60, 62 containing adjust. able dust-cores movable with the frame 70. The tuning of the cores is indicated by a pointer 82 which moves over a scale in the front of the apparatus and is operated by a linkage with the frame 70 comprising lever 78 sliding in elongated slot 80, bell-crank lever 88 and link 94. When the motor is energized the tuner is driven until a signal is received, whereupon a pulse is developed to de-energize a normally energized relay, Fig. 4 (not shown), whereby the motor is stopped and also a detent member is made to engage with the portion 8 of the clutch, thus stopping the gear train instantaneously, the clutch slipping to allow for the inertia of the motor. When the receiver is in this condition further tuning may be effected manually by rotation of the knob 96; alternatively the motor may be started again by depression of a member 118 operating upon a switch 128.

Abstract: 296,078. Hayn, G. Aug. 26, 1927, [Convention date]. Pulverulent-fuel burners. - In a locomotive or other furnace Bred by two or more multiple-orifice coal dust burners, one or more of which may be rendered inoperative, overheating of the burners not in use is prevented by maintaining their air supplies, wholly or in part. To ensure that the air supplies to the burners cannot be wholly cut off the dampers in the air conduits leading to the burners may be provided with apertures or arranged so that they cannot be completely closed. Fig. 3 shows a multiple burner body comprising two groups of burners r<1> - - r<4> and s<1> - - s<4> connected to separate supply conduits d. e. When one group of burners is to be cut off the damper controlling the coal dust supply to its conduit is closed entirely while the damper controlling the air supply is only partly closed. The air supply to the inoperative burners may be entirely cut off if the burner plate be made of such a thickness as to conduct away the heat from the inoperative burners quickly to the coal dust and air currents flowing through the operative burners.

[Class 40 (iii).] Incoming synchronizing impulses produce current impulses from a direct-current source 6 to energize the driving coil or coils 7 of a phonic wheel 1, which rotates the body to be synchronized. The coils 7 and the source 6 are in the anode circuit of a gas-filled discharge device 2, described in Specification 346,957, the control electrode 4 of which is maintained at negative potential, sufficient to prevent current flowing through the discharge device, by causing television signals to produce a voltage drop across a resistance 8. During the signal interruption at the end of each scanning-line, the control electrode regains a value sufficient to initiate a current flow through the discharge device. A rotary interrupter 14, driven by the phonic wheel, connects the anode 5 to the cathode 3 at periods so phased that the control electrode regains control over the discharge in the interval between successive synchronizing impulses. Initial phase correction is effected by adjusting the driving coils and the stationary element of the interrupter.
