Title: Improvements relating to machines for grinding and preparing rubber printing plates
IPC: B41D5/00
Filed: 1939-04-01
Abstract: 527,172. Printing surfaces. JENNINGS, H. W. K. (Fischer & Krecke Ges.). April 1, 1939, No. 10274. [Class 100 (ii)] [Also in Group XXIII] In a machine for " making ready" rubber printing plates, the plate rests, with the type side uppermost, on a table surrounding a grinding wheel, the plate being pressed down, at the required part thereof, on to the grinding wheel by a presser of appropriate shape and size. The machine comprises a table 1 carrying an arm 2 in the outer end 3 of which is slidable a vertical shaft 4 having at its lower end a head 5 bushed at 6 to receive a shaft 7 carrying a head 8 in which are mounted three pressers 17, 18, 20 of different shapes. The head 8 is drawn against the bush 6 by a spring 9 and has grooves to engage a tongue 11 on the bush to lock the required presser in operative position. The end 3 of the arm 2 has a cup shape and is threaded to receive an externally threaded sleeve 12, the upper face of which acts as a stop to limit the downward movement of a nut 14 screwing on the shaft 4 and provided with a cap 15 marked with a scale to co-operate with a pointer 16 on the.arm 2. The table 1 has on its under side a flange 19to which is secured a member 21 forming a bearing for a hollow shaft 22 carrying a fan wheel 23, whereby rubber dust is drawn through openings 24 in the table and removed through an outlet 25. In the lower threaded end of the shaft 22 screws the lower end of a shaft 26 carrying a grinding-disc 27, the shaft being adjustable to compensate for wear of the disc by a head 28a thereon and locked in adjusted position by a nut 28 ; the shafts 22, 26 are rotated by a belt 31 from an electric motor 29. The holder 8 is moved down to press the plate on to the disc 27 by means of an arm 43, which engages a pin 46 on the shaft 4 and is mounted on a shaft 44 moved by an arm 42 ; the arm 42 is operated, through links and levers 34, 37 ... 39 by a shaft 32 moved by a plate 33 adapted to be engaged by the knee of the operator. For grinding lines on the front side of the plate, a separate motor 59, Fig. 5, may be mounted on the machine to drive, through a flexible shaft 51 either a conical grinding-disc, for line grinding, or a cylindrical grinder operating with its end face for grinding individual type, the grinder being mounted in a holder 52 mounted on the shaft 7 or the head 8.

Abstract: 565,117. Fuel supply to carburetters. THOMPSON PRODUCTS, Inc. July 23, 1942, No. 10323. Convention date, Sept. 5, 1941. [Class 7 (iii)] The supply of liquid fuel to the inlet of a fuel pump 22 feeding a carburetter 16 is ensured at all altitudes by the use of an auxiliary pump 13 connected to two outlets from the fuel tank 14, Fig. 1, or to a single outlet as in Fig. 4. Pipes 36, 37 leading from these outlets are connected together before they reach the pump 13 so as to provide a sump 37a leading to the pump impeller 32, driven, for example, by an electric motor 33. The vapour bubbles forming in the fuel at higher altitudes are separated by the impeller and rise to the surface of the fuel through the pipe 36 or 37 which offers the least resistance, the liquid fuel being supplied to the pump 13 through the other pipe. The vapour escapes by a vent 14a. A hand pump 12 is also fitted in the delivery pipe 21. The pipes 36, 37 may be connected to separate fuel tanks. In another form, Fig. 4, a single pipe 61 leads from the tank to the pump 13c, a tapered throat 49b being provided leading to the impeller, so that the vapour bubbles ascend at the sides of the pipe 61. as shown, leaving a central path for the liquid fuel to flow to the pump.

Title: Improvements in and relating to the control of thermionic valve apparatus

Filed: 1934-04-10
Abstract: 436,384. Valve circuits. BEVAN, R. H. L.,' SMITH, H., and HILL, E. G., H.M. Signal School, Royal Naval Barracks, Portsmouth. April 10, 1934, No. 10757. [Class 40 (v)] The character of the voltage-time curve of a thermionic valve, the grid circuit of which includes a coupling condenser and grid resistance, is determined by the sign and /or magnitude of the input voltage. The Figure shows a thermionic relay designed as a morse frequency impulse amplifier, the output load being an electromagnetic relay. An additional relay M carries a contact-making armature T which puts resistance R2 or R3 in parallel with the grid resistance R1, depending on the anode current of the valve. The resistances may be connected to different values of grid bias voltage the normal value being such that the contact T is midway between Sand U. With a positive signal impulse contacts T and U are closed, and with a negative impulse T is connected to S. The effect is partial suppression of very strong signals and increased rate of delay of the impulse which avoids mutilation of a subsequent impulse. The relay M may be in the anode circuit of a subsequent valve. Specification 369,578 is referred to.

Title: Improvements in or relating to steam boiler installations incorporating heat accumulators
Inventor: BAIN KENNETH LINDSAY
IPC: F01K3/00
Filed: 1960-03-28
Abstract: 915,843. Steam regenerative accumulators; hot feedwater storage apparatus. DANIELS Ltd., T. H. & J. March 28, 1961 [March 28, 1960], No. 10904/60. Class 123 (2). In a steam boiler installation comprising a boiler B and an associated heat accumulator A arranged to store heated water when a demand for steam in the steam line SL falls, the accumulator is situated at a higher level than the boiler in order to permit gravity flow of the hot water to the boiler when the demand rises above that which can be supplied by the boiler operating at the mean firing rate which is chosen to give the most economical operation. Water enters the boiler via a feed pump F which, when the boiler water is below a preset level, is controlled by a level control switch E, the burners operating at the pre-set mean firing rate when the boiler has reached working pressure. If the steam consumption is less than corresponds to this rate the increase in pressure will cause a valve D in a pipe between the top of the accumulator and the steam space of the boiler to close, thus permitting water to be drawn up through a valve C in a pipe between the bottom of the accumulator and the water space of the boiler into the accumulator whence it will return by the same path to the boiler when increase in steam consumption causes the valve D to open. When the boiler water reaches the pre-set level the feed pump F is cut out by the control switch E which subsequently holds the boiler water level between the pre-set level and an upper level by operation of the valve C. A bleed valve G situated in a pipe connecting the top of the accumulator to the steam supply main opens should the pressure in the accumulator rise above a predetermined value. A pressure switch PSI in the steam line of the boiler operates to cut in an automatic burner control mechanism when the pressure in said line is outside a certain range. A reducing valve R in the steam line may be operated manually after the boiler has been shut down to provide a limited amount of low pressure steam from the storage in the accumulator and boiler. More than one boiler may co-operate with a single accumulator.

Abstract: 400,607. Spectrum analysis. HERAEUS GES., W. C., Hanau-on-Main. Germany. April 18, 1932, No. 11052. Convention date, April 18, 1931. [Class 97 (i).] Apparatus for producing sparks for spectrum analysis comprises an adjustable oscillatory circuit I containing a spark-gap F and a condenser C the discharge from which is so timed that it takes place at a fixed voltage, means being provided for quenching the spark rapidly. For the latter purpose an oscillatory circuit II is provided coupled to and in tune with the circuit I. To regulate the voltage of the discharge the condenser C is charged by alternating current from a rotary converter EU through a transformer T and a rotary interrupter Z in the circuit I is driven synchronously with the converter EU, so that discharge takes place at a predetermined phase of the charging current. It is stated that a similar effect is produced if the period of the circuit formed by the condenser C and transformer T is that of the charging current. The spark-discharge should be quenched after one or two oscillations and if the circuit II is insufficient for that purpose a quenching spark gap R may be provided in the circuit I. Means may be provided in known manner for blowing vapour away from the spark-gap.
