Labels may be applied from both sides of the belt simultaneously and the articles may be in zig-zag formation. Alternatively, stamp pressers and colour rollers may be used for stamping the articles.
Patent GB-816721-A (GB)
Title: Improvements in or relating to methods for manufacturing plate-shaped or cylindricalor tubular insulating elements from mineral wool
IPC: B29C33/00
Filed: 1957-04-29
Abstract: Plate-like or cylindrical or tubular insulating elements are made from mineral wool, e.g. stone-wool or glass-wool by immersing the material, while contained in a mould having a perforated circumferential wall, in a liquid synthetic resin-based binding agent such that the synthetic resin penetrates into the fibrous material only superficially.  A suitable synthetic resin is melamine-formaldehyde resin.  The mineral wool is supplied on a conveyer belt between a pair of rollers and thereby formed into a coherent layer with a thickness of about 1/4 in. under a slight pressure.  The layer is wound on a core to the desired thickness and then placed in the perforated mould which is immersed in the liquid binding agent.  The fibrous body impregnated with liquid and while still in the mould is rapidly rotated and thereafter dried and hardened.  By this means the excessive liquid is thrown out of the body and by the centrifugal action the liquid in the body is driven out from the interior. The body is thus strengthened on its outer side while the insulating capacity of its inner side is increased. To this end a mould containing the fibrous mass is clamped into a rotating head in such a manner that a hollow space is formed around the axis of rotation.  Through a bore in the rotating head a hot gas is introduced into the hollow space and flows through the fibrous layer in the direction of the centrifugal force and out through the perforated mould walls.  When insulating elements for pipe-lines are being made, the cylindrical core is withdrawn from the fibrous body after the immersion step, hot gas being introduced into the interior of the cylinder-shaped element during the centrifugal step. Plate-shaped fibrous bodies are obtained in flat moulds and the moulds may be joined to a polygonal drum for subjecting them to the centrifugal step.

Filed: 1945-05-17
Abstract: 592,777. Control of A.C. motors. SCHWARTZ, B. May 31, 1945, No. 13696. [Class 38(iii)] A control system for an A.C. commutator motor, arranged for change - over from shunt characteristic operation to series characteristic, and vice versa, particularly for crane hoists and the like, comprises a regulating transformer IR, which may be a single induction regulator, with one winding SER series connected in the stator circuit ST of the motor and the other winding PR connected permanently to the primary winding PT of another transformer T which has the secondary winding SET connected across the rotor C of the motor, and means such as a switch 1 for connecting the interconnected windings of the two transformers to an A.C. supply to obtain shunt characteristic operation and disconnecting them from the supply for series characteristic. The regulating transformer IR may be tapped to provide connections for changes of the relative phase positions between its primary and secondary windings for speed adjustment. An induction regulator may be employed in place of transformer T. Speed regulation is obtained by angular adjustment of the induction regulators when these are employed. In a modification, Fig. 2 (not shown) the interconnected windings PR, PT are connected to the stator windings ST by means of a switch for shunt characteristic operation and disconnected therefrom for series characteristic. In a further modification Fig. 3, (not shown), either of the systems of Figs. 1 and 2 is adapted for running the motor as an induction motor near its synchronous speed by providing a switch for short-circuiting the primary winding of the second transformer, this being substantially equivalent to short circuiting the rotor windings of the motor via the brushes. A second stator winding, preferably comprising a lower number of poles, may be provided to obtain a higher motor speed for hoisting or lowering an unloaded hook. Load discriminators may be provided to prevent the speed exceeding a predetermined value under load. Specifications 518,124 and 555,838 are referred to.

Title: Improvements relating to code converters
Inventor: ROBINSON NIGEL DAVID
IPC: H03M7/12
Filed: 1958-05-02
Abstract: 921,330. Binary to binary-coded-decimal converters. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 4, 1959 [May 2, 1958], No. 13996/58. Class 106 (1). In a system for converting a pure binary number into a binary-coded-decimal number the pure binary number is shifted, most significant bit first, from a register 2 into an accumulating register 1 which is notionally divided into decimal stages R0, R10, R100, &c., each comprising six bits, and after each shift the binary " filler " number 110110 ( = 2<SP>6</SP> - 10 = 54) is added to each decimal stage R0, R10 . . ., &c., and is immediately subtracted from all those decimal stages that do not send a carry to their adjacent stages. The effect of this is that when any decimal stage contains bits which represent, in the binary scale, ten or more, then ten is subtracted from that stage and one is added to the next decimal stage. The circuit described is controlled by a unit 3 and each cycle of operation comprises the following steps. First the registers 1 and 2 are shifted one position, register 2 to the right and register 1 to the left. Then a pulse or a line 15 and on an " add " line 8 causes " filler " digit generators 16, 17 . . . 21 to add a filler digit to each decimal stage. This is followed by a further pulse on line 15 together with a pulse on a " subtract " lead 8 but this time the pulse on lead 15 is inhibited from reaching the filler digit generator of any stage from which a carry has occurred so tnat the filler digit is only subtracted from those stages not producing a carry. This cycle is repeated. The register 2 contains 36 bits so that a decimal register with 12 stages is required. Register 1, however, only contains 6 stages and thus after only 18 or 19 cycles bits may overflow from the left-hand end of register 1. These bits are entered into register 2 which is gradually being emptied. Thus after 36 cycles the lowest 6 decimal denominations will be correctly registered in register 1 but the higher denominations, which will be in register 2 will not have been properly converted. This situation is remedied by transferring the contents of register 1 to a further register (not shown) and then shifting the contents of register 2 into register 1 during a further 36 cycles. The shift register 2 and the accumulator register 1 could be as described in Specifications 893,355 and 893,353 respectively, both these Specifications being referred to.

Abstract: 976,942. Pneumatic despatch apparatus. SAMSON ENGINEERING CO. Ltd. July 12, 1963 [April 12, 1962], No. 14132/62. Heading B8A. In a pneumatic tube ring system 1, Fig. 1, having a plurality of receiving stations 3 to which the carriers are selectively directed by diverter flap device 5, the flaps are normally disposed in the position for diversion of the carriers to the receiving stations 3 and are operated selectively to retain the carrier in the ring system until it reaches the required station. The arrangement ensures the immediate ejection of carriers in the event of a failure of the selective signalling system and prevents continuous orbiting. Movement of the flaps is controlled from sensing stations 8 at which all but one selected brush contact are connected to the flap control circuit 12. The flaps are thereby caused to operate and retain the carrier in the ring circuit at all stations except the selected delivering station. The systems may incorporate a pressure sensitive device 16 which operates switches to prevent the insertion of carriers when the system is overloaded. Specification 955,737 is referred to.
