Title: Impression control apparatus for typewriters
IPC: B41J7/94
Filed: 1975-10-15
Abstract: 1497108 Selective printing SCM CORP 15 Oct 1975 [8 Jan 1975] 42353/75 Heading B6F In a typewriter the energy imparted to a type lever 118 is derived from power roll 36, and the energy transmitted from a motor via belt 32 to the roll 36 is adjusted by a spring 176, which absorbs energy when relative movement between the roll 36 and pulley 34 occurs. As shown the belt 32 engages the teeth on the pulley 34. The pulley 34 ususally drives the roll 36 via a bumper 164 on a bushing 148 attached to the power roll 36. When a type lever is activated, its pawl 108 engages the roll 36 and thereby slows the roll 36. This causes relative movement between the pulley 34 and roll 36 and also tensions spring 176. The greater this relative movement is, the less is the energy imparted to the typelever. A control member 180 has a stop 184 which limits this relative movement. The control member is pivotal about bolt 196 and is moved by axial movement of the surface 212 which is followed by the surface 190. The member 210 is axially adjusted by manual control wheel 232 which pivots arm 216 about screw 222.

IPC: C08G18/63
Filed: 1965-10-11
Abstract: 1,126,024. Modified polymeric polyols and polyurethanes produced therefrom. IMPERIAL CHEMICAL INDUSTRIES Ltd. 5 Oct., 1966 [11 Oct., 1965], No. 42979/65. Headings C3C and C3G. Modified polymeric polyols are obtained by polymerizing an ethylenically unsaturated compound in the presence of a cationic polymerization catalyst and a polymeric polyol containing at least 0À8 halogen atoms in the molecule. The polymeric polyol may be a polyester, polyesteramide, polyether, polythioether or polyacetal. The halogen atoms may be introduced into the polymeric polyol either by inducing suitable halogen containing compounds in the polymerforming reaction mixture or by reacting a preformed hydroxylated polymer with a halogencontaining epoxide. A list of suitable ethylenically unsaturated compounds is provided with styrene and substituted styrenes being preferred. Conventional cationic catalysts are used, e.g. Lewis acids. The modified polymeric polyols may be reacted with organic polyisocyanates to produce polyurethanes in the presence or absence of a gas-generating agent, e.g. water or an inert liquid of low boiling-point. The example describes the reaction of epichlorohydrin and oxypropylated glycerol in the presence of BF 3  in diethyl ether followed by the polymerization of styrene on to the so-formed polymeric polyol in the presence of BF 3 . The modified polymeric polyol is then reacted with tolylene diisocyanate in the presence of stannous octanoate, triethylene diamine, water and a siloxane/oxyalkylene block copolymer to produce a foamed polyurethane.

Title: Vacuum Gap Devices for High Temperature Operation
IPC: H01T2/02
Filed: 1966-09-27
Abstract: 1,162,392. Cold cathode tubes. GENERAL ELECTRIC CO. 27 Sept., 1966 [28 Dec., 1965] No. 43163/66. Heading H1D A triggerable vacuum gap discharge device suitable for use at high temperatures includes a pair of primary arc electrodes which are free of gas or gas-producing impurities to the extent that, subsequent to reabsorption of plasma ions after arcing, the pressure does not rise above 10<SP>-5</SP> torr, one of the primary electrodes including a cavity opening into the gap therebetween and housing a trigger assembly formed by a pair of spaced metal members one of which is connected to the primary electrode; the metal members of the trigger assembly serve, upon the establishment of an arc between them, as a source of ionised metal vapour for injection into the primary gap. The trigger gap 20 is formed by a groove cut through a metallic coating 18, 19 formed on the surface of the insulator 4 which projects through a cylindrical aperture into the conical opening 10 in the main cathode 6. Connection is made to layer 19 via a lead 12 and the plate 11, layer 18 being connected to the main cathode 6. Cathode 6 and anode 7 of the main gap are supported by metal terminal discs 5 and 3, respectively, which are sealed to alumina ceramic envelope portions 1 and 2, the latter being shielded from condensed metal vapour by electrode 14. The main electrodes are of the copper, beryllium, or alloys thereof, and the layers 18, 19 either of the same material, or of aluminium, iron, nickel, cobalt, lead, or beryllium tin. Upon the application of a trigger pulse across the gap 20, metal from layers 18 and 19 is vaporized and ionised, and projected by the magnetic field of the discharge into the main gap between electrodes 6 and 7. To ensure a copious supply of metal vapour, the conical portion of electrode 6 is also provided with a similar metallic layer 21. In a modified arrangement (Fig. 3, not shown), the trigger gap is protected from the main discharge by an overhanging portion of the wall of cathode 6.

Title: Improvements in aircraft propulsion power units
Inventor: MARCHANT FRANCIS CHARLES IVOR
IPC: B64D27/10
Filed: 1960-12-15
Abstract: 1,013,116. Aircraft jet propulsion engines. BRITISH SIDDELEY ENGINES Ltd. Dec. 12. 1961 [Dee. 15, 1960], No. 43218/60. Heading B7G. Fig. 2 is a half plan view of the forward part of an aircraft jet propulsion unit comprising an axial flow compressor in a casing 1 with an air intake 2, and a gas turbine in a casing 5 of less diameter than casing 1, the turbine driving the compressor, and the compressor feeds air to an annular chamber 6 having an outlet defined as to direction and cross-section by the axis III and internal periphery of an annular bearing 9, and a nozzle 8 is rotatably mounted on the bearing. The fore-and-aft plane containing the axis III of the bearing is inclined to the transverse horizontal plane at a droop angle of 15 to 45 degrees, as shown in the rear view of Fig. 4, and its least distance from the compressor axis II lies between zero and the difference between the external radii of the compressor casing 1 and the annular bearing 9. The axis III as viewed normally to the aforesaid fore-and-aft plane, is inclined to axis II at a divergence angle of 50 to 75 degrees. The angle through which the nozzle deflects the air flow is between the divergence angle and an angle eight degrees less than the divergence angle, and the droop and deflection angles are approximately complementary. For example, the divergence angle, droop angle, and deflection angle may be 60, 35, and 54 degrees respectively. In the forward thrust position, the line of discharge IVa is then inclined outwardly of the fore-and-aft direction by an angle n 1  of about six degrees. This assists the jet in clearing the body or nacelle in which the unit is housed. When the nozzle is rotated (through rather more than 90 degrees) so as to provide a lifting thrust, the line of discharge is inclined downwardly and outwardly of the vertical by about eight degrees. By the above arrangement, the frontal area of the engine is decreased, as compared with an arrangement in which axis III is at right-angles to axis II. The compressor also delivers air to a high-pressure compressor in casing 4, this being driven by a high-pressure turbine upstream of the first turbine. The turbine exhaust gases discharge through a similarly arranged nozzle 27, Fig. 4, of lesser size than nozzle 8. Nozzle 27 is also inboard of nozzle 8, permitting the nacelle to taper sooner, and thus to be shorter. In Fig. 4, two such units, mirror images of each other, are installed side-by-side in a fuselage 25. Alternatively, one such unit may have two symmetrically arranged nozzles 8 and two such nozzles 27. The nozzles are moved in unison. The chamber 6 may contain combustion equipment.
