Abstract: 1,125,002. Bolt-hole bushes. BRAITHWAITE & CO., ENGS., Ltd. 24 Feb., 1965 [27 Nov., 1963]. No. 7884/65. Divided out of 1,125,001. Heading F2H. A tubular bush comprises a flanged sealing member 10 made of soft distortable material such as rubber, an internally screw-threaded insert 12 in the tubular member 10 at the end opposite the flange such insert being made of relatively inflexible material and a flanged locking member 11 of relatively inflexible material, the locking member 11 being externally screw-threaded at 19 to correspond with the internal screw-thread on the insert 12 and having a bore of double hexagonal shape at 17 for engagement by a tool for rotating the member. The sealing member 10 is passed from one side through one or more apertured plates (20), the tubular part of the looking member 11 being inserted into the sealing member 10 and screwed into the insert 12, the tubular part 13 of the sealing member being thereby compressed and bulged outwards into engagement with the other side of a plate 20. The bore in the bush may be closed by a plug 22 having a short externally threaded body which engages the internally screw-threaded part 18 of the bore in the locking member, the thread 18 being of opposite hand to the external thread 19 of the locking member 11. The head of the plug 22 has an axial re@ess of double hexagonal section such that it can be rotated by a tool. In a modification the screw-threads 18 are omitted and studs are provided on that side of the flange of the looking member opposite the tubular part thereof, for connecting the member to a pipe flange.

Abstract: 769,409. Protective cut-out arrangements; control of A.C. motors. STONE & CO. (DEPTFORD), Ltd., J. March 15, 1955 [March 18, 1954], No. 7912/54. Classes 38(3) and 38(5) A phase-sequence discriminatory starting switchgear for a polyphase motor comprises a star-connected network of which one leg contains a line contactor or a relay p controlling a line contactor (not shown), another leg contains a resistor r<SP>2</SP> having an ohmic resistance equal to that of the first leg, or a further such contactor or relay and the third leg contains a capacitor K. In the arrangement shown the relay p is a direct-current no-volt relay and is associated with a bridge rectifier q and ballast resistance r<SP>1</SP>. The value of the capacitor K is such that when the phases R, Y and B have the desired phasesequence, the relay is energized. The relay may effect the operation of a starting contactor only when the phase-sequence is correct or alternatively may control a change-over contactor, which on operation, would give the appropriate phase-sequence for starting the motor in the correct direction. If a second relay is provided as indicated above, the two relays may control line contacts, so that closure of either relay and its associated contactor would give the correct phase-sequence. In each case the winding or windings of the con- .tactor or contactors may be connected in the network in place of the relay or relays. In place of the D.C. relay and rectifier an A.C. relay or contactor may be used.

Filed: 1929-01-14
Abstract: 314,128. Poliakoff, J. Jan. 14, 1929. Transformers. - In audio - frequency transformers for thermionic valve circuits in which equal amplification over a wide range of frequencies is obtained by providing a short-circuited tertiary winding on the core, the effective ratio is maintained by adding to the secondary winding or subtracting from the primary winding a number of turns depending upon the inductance resistance and capacity of the windings. A formula for calculating the number of turns to be added or subtracted is given in the Specification. Various ways in which the windings may be arranged in relation to each other are shown on the drawing in which P indicates the primary, S the secondary, W the tertiary winding, and T the added secondary turns. In the arrangements of Figs. 1 and 2, the tertiary winding is wound over the secondary coils.

[Class 100 (i).] A wrapping foil, or other web having spaced printed impressions and perforations between the impressions, is fed to a cutting-device by a feed member which advances the web to an extent slightly greater than the distance between the impressions, and the web is then withdrawn to an extent limited by a stop which falls into a perforation in the web. The web 1, Figs. 1 and 2, is fed over a table 24 to the shears 34a, 34b by scissors-like tongs 2 pivoted to a slide 11 which is reciprocated by a cam 17 on a shaft 45 acting through linkage 18 .. 21. The tongs are closed by a spring 4 and opened after the actuation of the shears, by mechanism actuated by a cam 3 on the shaft 45. A pivoted member 23 resting upon the web 1 above a slot A in the table 24 thereupon withdraws the web until a stop 26 resting upon the web drops into a perforation to arrest the backward movement. The stop 26 has a vertical edge 35, Fig. 5, to engage the perforation and an inclined lower surface 27 to allow of free forward movement of the web. The stop is carried by a lever 29 which is pivoted to an arm 31 adjustable along a bar 32 and is provided with a counterweight 30. The stop may comprise a number of independent plates 26a .. 26d, Fig. 6, pivoted to the lever 29 or to a rigid arm so that at least one of the plates will engage a perforation even if the web deviates laterally.

Filed: 1928-03-21
Abstract: 309,708. Ward, W. J. V., and Imperial Chemical Industries, Ltd. March 21, 1928. Methanol.-Methanol obtained by the catalytic hydroseaatMn of oxides of carbon is purified by treatment with a s,alting-out solution and a solvent for hydrocarbons which is substantially immiscible with the mixture of methanol and salting-out solution. The solvent for hydrocarbons mav be a hydrocarbon such as benzene. In one example, a methanol traction is distilled from the product obtained by passing a mixture of carbon monoxide and hydrogen at elevated temperature and pressure over a catalyst comprising zinc, chromium, and manganese oxides. The distillate is treated with brine and benzene, the benzene iayer is removed, and the extraction is repeated with a further amount oi benzene. The methanal is then distilled off from the brine, the main bulk of distillate being collected separately from the first runnings, which are impure. The benzene may be purified by distillation and used again. In another example, a mixture of impure synthetic methanol and benzene is treated, with brine in a column, impure benzene being taken off at the head of the column and a brinemethanol mixture at the base.

Abstract: 1416915 Transistor analogue storage circuits DELMATIC Ltd 2 May 1974 [21 Feb 1973] 8562/73 Heading H3T [Also in Division H2]  A dimmer circuit for a lamp comprises a capacitor 11 the state of charge of which is progressively variable by a manually controlled switch 49, 41, 42 to enable the power supplied by a triac 13 to the lamp to be progressively varied. A terminal 40 is connected to a clipped half-wave rectified supply so that when a terminal 49 of the switch is pressed into engagement with a terminal 42, the capacitor 11 is progressively charged via a diode 46. The longer the terminals 49, 42 are held closed the earlier the triac is fired so that the brighter is the lamp. When the terminals 49, 41 are closed the capacitor 11 discharges via the diode 45 during the gaps between the half-waves of the supply to the terminal 40 so that the lamp is progressively dimmed. The output of a high input impedance amplifier 22 or an equivalent F.E.T. charges a capacitor 24 until the threshold value of a unijunction transistor 25 is reached whereupon the discharge of this capacitor supplies a trigger pulse to the gate electrode of the triac. An input terminal 31 is connected to a clipped full wave rectified supply which enables discharge of the capacitor 24 at each zero of the supply.
