Abstract: 1,169,285. Drying and filtering fluids; air filter. SPIRAX-SARCO Ltd. 5 July, 1968 [29 July, 1967], No. 34976/67. Headings B1L and B1T. Fluid drying and/or filtering apparatus, of particular use for drying air, comprises a drying and/or filtering cartridge, containing for example silicon gel and/or wire wool, located in a mounting in the fluid flow line, and so adapted that the cartridge may be replaced when expended by pressing a fresh cartridge against it to expel the used cartridge and replace it with the fresh one without loss of pressure in the flow line. Thus cartridge 5a of rectangular cross-section is located in the flow line defined by ports 4 in mounting 1 (see Fig. 2). When expended, fresh cartridge 5b is pressed down Qn top of it, thereby expelling used cartridge 5a, loss of fluid being prevented by means of tight resilient seals 9. In Figs. 4, 4A, the mounting comprises a hollow cylinder 17 with entry and outlet ports 16. Cartridge 18 has ports 19 which register with ports 16 and sealing rings 20. A used cartridge is expelled by urging a fresh cartridge along tube 17 against it. To prevent gas pressure within tube 17 tending to force the fresh and used cartridges apart, cartridge 18 may have a screwthreaded socket at one end and a corresponding spigot at the other end (see Figs. 7-9, not shown). In other embodiments, the pressure loss-preventing seals are contained in the body of the mounting (see Figs. 5, 5A, not shown), and a tray-type transfer device is used to accommodate both the in-use and unused cartridge (see Fig. 6, not shown). In yet another embodiment (see Fig. 10, not shown), the sealing means preventing loss of pressure during replacement consists of ball valves (41) located in ports (40) of mounting (38). Fresh cartridge (42) is slid at right angles to the paper into position in the mounting, and then raised by lever (45) whereby spigots (44) lift the ball valves off their seatings and permit fluid flow to be resumed.

Abstract: 902,796. Starting prime movers. BOSCH G.m.b.H., ROBERT. Oct. 14, 1960 [Oct. 17, 1959; Oct. 31, 1959], No. 35209/60. Class 38 (4). [Also in Group XXVII] A rotary speed responsive relay system which prevents operation of a starter motor when an engine is turning comprises a transformer 38 whose primary winding 35 is in series with an ignition coil primary winding 22 and a contact breaker 27. The secondary winding 37 of the transformer charges through a semi-conductor rectifier 43, a capacitor 48, the voltage across which rises as a linear function of the engine speed and cuts off a transistor 40, which deenergizes a relay coil 47 and opens contacts 63, 65 in the starter motor relay circuit. At the same time, another relay 49 may be unshunted, which through its contacts 51, 52, a contact 54 and rail 55 shuts an exhaust brake flap 14. The discharge time of the capacitor 48 is about one second to allow the engine to come to rest before allowing a re-start. In another embodiment, the starter motor relay is connected through a rectifier either to the capacitor 48 or an additional transformer primary winding so that energy stored in the relay coil is transferred to the capacitor to prolong the discharge time. The transformer may have an additional secondary winding and series rectifier to give a full wave output to the capacitor, and an amplifying transistor may be interposed between the transistor 40 and the relay.

Title: Phase discrimination circuits
IPC: H03D13/00
Filed: 1974-08-09
Abstract: 1475532 Phase sensitive switch FUJITSU Ltd 9 Aug 1974 [9 Aug 1973] 35284/74 Headings H3A and H3P A circuit for detecting whether the phase of a first signal e a  leads or logs that of a second signal eb compares the relative amplitudes of the two signals at one instant, stores the result and compares it with a comparison obtained at a later instant. In a frequency discriminator, Fig. 9, for an a.f.c. system, a first signal e 1 , and quadrature components of a second signal e 2  are applied to two mixers 1D, 1E to produce two quadrature signals e a , e b  at the difference frequency. The complements of these signals ,e a  e b  are also produced and the two pairs of complementary signals are applied to respective bi-stable circuits to produce rectangular binary pulses which are applied via NAND gates 21A to a further bi-stable 21B which stores their relative values. The two complementary outputs from bi-stable 21B are then gated in 21D with one of the outputs e a <SP>1</SP> from one of the first pair of bi-stables resulting in a signal at the difference frequency at T3 and a constant signal at T4 or vice versa depending on whether e b  leads or lags e a  by 90 degrees, i.e. depending on which input signal e 1 , e 2  has the higher frequency. The resulting output is then integrated to provide the control signal for an oscillator providing one of the two inputs e 1  or e 2 . In a modification, Fig. 8(a) the complementary signals e a , e b  are not used, and the signal e b  is fed to one of the two NAND gates 21A directly and to the other via an inverter. A second inverter is also provided in the path coupling e a  to the gates 21D. In this arrangement, if the signal on e b  leads that on e a , the bi-stable 21B will be in its SET state when a "0" appears to on line e 0  to open gate G3. Conversely if e b  lags bi-stable 21B will be in its reset state to open gate G4.

Convention date, March 10. [Class 100 (ii).] A lithographic transfer press comprises a reciprocating flat bed 3, normally carried by idler rollers 4, and a rubber covered pressure roller 8, having means for forcing the pressure roll downwards towards the bed during the movement of the bed and means for releasing and rendering said means ineffective at a predetermined point in the movement of the bed. The bed 3 carries the plate 53 and a keyboard 44 carrying the transfers, and is moved forward by a supporting roller 5 at the instant that pressure is applied by the roller 8. Rollers 5, 8 are slidably mounted in bearings 6, 9, the roller 8 being forced upwards by compression springs 10 and downwards by hydraulic pistons 11, actuated by a hand pump 12 and an oil reservoir 13. The return pipe 16 carries a check valve 17. Toggle levers 27, 28 actuated by hand-lever 32 are arranged so that, when the lever 32 is moved in one direction, the roller 5 is raised to contact the bottom of the bed, while moving it in the opposite direction drops the roller 5 and raises a reversing roller 24 to reverse the motion of the bed. The valve 17 prevents pressure being applied unless the roller 5 is elevated, since it is held open by a vertically moving rod 37 pivoted to a lever 38 arranged to raise the valve stem 39 when the bearing 26 for the roller 24 is raised. A continuation on the rod 37 is adapted to be lifted by a wedge 40 carried by the bed so that the pressure is automatically released when the bed reaches the end of its travel. Registering devices 41, Fig. 3, are provided at the forward edge of the bed and are secured to a shaft 42, rotatably carried in extensions attached to the bed, and actuated by a spring to cause the fingers 41 to take up the position shown in dotted lines automatically upon release. For this purpose, a pivoted latch 46 engages a jaw 49 of a collar 50 secured to the shaft 42 to hold the fingers 41 over the bed but which allows them to fly forward when the latch 46 is raised by passing over a cam 51 carried on one of the machine tie rods 2. The fingers 41 are turned back to position by a handle on the shaft 42.
