Title: Improvements in time switches for controlling electric circuits
IPC: G04F3/02
Filed: 1958-08-06
Abstract: 860,042. Control of motors; controllers; actuation of switches. FRACHON, M. Aug. 6, 1958 [Aug. 13, 1957], No. 25148/58. Classes 38 (3) and 38 (5). A time-switch comprises an electric motor 1 driving a cam 3 which engages a spring-biased roller 4 carried by a micro-switch unit 5 pivoted at point 6, the actuating button 7 of the switch being adapted to abut an adjustable cam 8 when the cam 3 permits lowering of the switch at the position of rest of the apparatus. The switch 5 then engages contact 10, whereby actuation of push-button 17 energizes relay-coil 14 to close contacts 14a, 14b, and the motor is started whilst the relay is held closed through contact 10. After a predetermined period, the actuating button 7 leaves the cam 8 and the switch 5 is moved to the contact 9. The relay is deenergized, but the motor continues to operate until the roller 4 falls from the highest point of cam 3 and the switch 5 re-engages the cam 8. An external circuit controlled by the switch may be connected to lines 13, 18, or the circuit may be closed by relay-contact 14c. In another arrangement, which dispenses with a relay, the motor drives an additional cam for stopping the motor after one revolution of the cam 3, Fig. 4 (not shown). In a further embodiment, the motor operates at a higher speed during the idle period between the de-energization of the relay and stoppage of the motor, Fig. 8 (not shown). The motor may be reversible, the motor being started in one direction at a position of rest of the cam 3 to move the micro-switch 5 until its actuating-button engages a fixed abutment. The motor is then reversed until the cam is returned to its position of rest. A further cam closes an external circuit substantially as soon as the motor is started, and opens the circuit when the motor stops, Fig. 10 (not shown). Specification 858,552 is referred to.

Abstract: 1,089,445. Converting. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 15, 1965 [June 18, 1964], No. 25238/65. Heading H2F. In an arrangement for supplying sawtooth current to the deflection coils 3 of a C.R.T. and for supplying E.H.T. from the flyback pulses, a transductor 10 whose saturation is controlled (through winding 15) in dependence on the beam current controls the coupling between a primary winding 2 and the E.H.T. output winding 7 in such a way as to maintain a constant output voltage and not lose third harmonic tuning. As shown, the deflection transformer 2 feeds the deflection coil 3. Also, from the tapping 4 it feeds a series circuit comprising an inductor 5 and the primary winding 6 of a transformer whose secondary winding provides the E.H.T. through a diode 8. The inductive winding 10 connects a further tapping 11 on the transformer 2 to the winding 6. If the inductance 10 is large with respect to the inductor 5, the winding 6 is effectively connected to point 4. If, however, inductance 10 is reduced-and this may be effected by varying the saturation of core 14- then the supply to 6 is derived from point 11. By making the saturation vary in dependence on the output as derived across a resistor 17 and applied to an amplifier 16, the required constant voltage output may be obtained. More elaborate embodiments are also disclosed (Figs. 2 and 3, not shown).

Title: Improvements relating to steam generating systems and apparatus
IPC: F22B1/14
Filed: 1929-08-21
Abstract: 340,295. Indirectly heated steam boilers. BAUMANN, K., North woodhouse, Barnfield, Urmston, Lancashire. Aug. 21, 1929, Nos. 25503/29, 34957/29, 34958/29, 34959/29, and 10343/30. [Classes 123 (ii) and 123 (iii).] Steam from water-tube boilers having one or more separate evaporators is passed through a succession of superheater elements and heating elements alternating therewith arranged in the water space of the boiler drum or drums and in one or more evaporators or in the evaporators only. In the plant shown in Fig. 1, steam from the boiler drum 2 passes together with steam from evaporators 4, 5, 6, alternately through superheaters 7, 9, 11, 13 and heating elements 8, 10, 12 in the evaporators, the finally superheated steam being led to a steam consumer 14. The superheater elements may be arranged in counterflow to the direction of the furnace gases or in parallel flow: thus steam may pass through the first element in a counterflow and the second in parallel flow (Fig. 11). Several nests of heating elements may be contained in a common drum. An evaporator may constitute a separator for the boiler drum. One or more evaporators may receive feedwater from sources different from that supplying the boiler ; in one arrangement the drum and evaporators which may not be connected on the water side may receive feed alternatively from two sources. The boiler tubes may line the furnace walls as shown in Fig. 11, and the roof tubes may be finned or covered with refractory material at the parts 35, 54 as a protection of a superheater chamber 34 and the drum 33 against the furnace heat and their intermediate parts 36 staggered to allow ingress of furnace gases into the superheater chamber. In this construction the evaporator or evaporators 57 comprise vertical cylinders with hairpin heating elements 58. The water spaces in boiler drum and evaporator are connected and the level controlled by means of a throttle valve in a connecting steam pipe 40. The water level may be varied to control the heat given up by the heating elements 58 and thus the final temperature of outgoing steam. This may also be controlled by means of a valve-controlled byepass 63 between the inlet and outlet chambers of the heating elements.

Title: System for Stacking and Transporting Sheet Material
Inventor: DEAN GEORGE ALLEN
IPC: B65H15/02
Filed: 1967-06-03
Abstract: 1,179,857. Stacking sheets; endless conveyers; suction lifting heads. DEAN RESEARCH CORP. 3 June, 1967, No. 25738/67. Headings B8A, B8H and B8R. Apparatus for stacking and transporting sheets comprises a support carrying a hollow head connected to a source of vacuum, the head being recessed for the reception of a stack of sheets, means for raising individual sheets into the head, and a levelling plate contained in the head which contacts the top sheet of the stack. General arrangement.-A trolley 4 rides on overhead rails 2, 3, Fig. 1, and carries a hanger 7 and linked support 9 for the suction head. Sheets 26, which may be glass, are supplied by conveyer belt 25, and introduced into stack 28; when the stack is complete, trolley 4 is traversed and the stack is removed to a discharge point and the head is rotated in the direction of arrow 32. Suction head.-The head, Figs. 1 and 2, has a top 10 and at least one side, preferably two, 11, 12, provided with a cavity 13 connected to a vacuum source. A levelling plate 15, fitted with an actuator 16, e.g. an hydraulic ram, has perforations in its sides 19, 20, and in the underside of its ceiling 17 so that a hollow space 18 is formed in the plate which communicates via the perforations with cavity 13. Rubber or other elastomeric seals 23 are provided to prevent loss of vacuum. In operation, actuator 16 lowers levelling plate 15 and the stack of sheets 28 until the lowest sheet of the stack contacts a sheet 26<SP>1</SP> located on the conveyer 25 immediately beneath the head; this latter sheet then comes under the influence of the vacuum, and is retained with the stack when the levelling plate 15 is raised. Depositing of a completed stack on a receiver is achieved by releasing the vacuum. Alternative stacking devices.-In the case of heavy sheets, the conveyer is formed of a number of parallel belts (35, 36, 37), Figs. 4 and 5 (not shown), a table (38), having raised ribs which co-operate with the spaces between the belts, can be lifted under the action of a ram (39) to bring individual sheets carried on the conveyer into contact with stack 28, and hence into the range of the vacuum in the suction head. A pneumatic device which detects the presence of the lowest sheet in the stack and actuates the raising mechanism for the levelling plate 15 can also be incorporated, Fig. 6 (not shown). If large glass plates are scored before stacking. Fig. 4 (not shown), then, after stacking and transportation, they may be broken into smaller plates just prior to release. Sheet feeding.-The use of the apparatus can be reversed so that a full stack of material can be picked up and then traversed into position over the endless conveyer. The levelling plate is then lowered stepwise and sheets are delivered individually on to the conveyer.

Abstract: 1302718 DC-DC conversion RCA CORPORATION 28 May 1970 [2 June 1969 3 June 1969] 25765/70 Heading H2F [Also in Division H4] The EHT supply for the cathode-ray tube in a television receiver utilizes a voltage multiplying circuit that includes a resistance 25R in the first branch so that the focus voltage tracks variations in EHT voltage. The output from the horizontal deflection circuit 12 of a television receiver is fed to a transformer 16 the output of which is coupled by capacitator 22 to a voltage multiplying circuit comprising diodes 25 ... 37 and capacitors 24 ... 36. A voltage dividing network is linked to terminal 41 to produce a focus voltage. The electron beam current passes through a beam current sensing circuit 42 which may take one of two forms. In one case if the electron beam current is excessive it causes a transistor (250), Fig. 2 (not shown), to switch to a non-conducting state, which in turn changes the bias voltage on transistor (247) of a video amplifier to limit the beam current. Alternatively the beam current may be used to apply a control voltage to a pulse regulator tube, thus control the EHT voltage.
