Apparatus for use in the manufacture of spring interiors for mattresses and operative to trim by severing and deform helical wires comprises a support, and operating member mounted on the support for rotational and axial movement between a first position in which the end portion of a helical wire 25 to be trimmed can be passed through the apparatus and a second position, the support and the operating member including cutter means for trimming the helical wire and the operating member having abutment means for engaging the end portion of a trimmed helical wire to bend it backwards towards the body of the helical wire and inwards towards the axis of the helix to form a loop in said end portion. The apparatus comprises a pair of semi-cylindrical jaws (not shown) formed with grooves on their inner faces so that when the jaws are closed the grooves define a helical path along which the helical wire can be screwed. The helical wire projects from the jaws and passes through a head 10 on one end of a shaft 11 extending through a fixed sleeve 12. The other end of the shaft has a screw-thread 13 which passes through a nut in a bracket 14 so that, on rotation, the shaft is raised or lowered. A quadrant 15 fixed to the extreme end of the shaft engages a rack 16 reciprocable by a pneumatic cylinder 18. The rack is guided by rails 20 and an adjustable stop 19 limits its stroke. When a helical wire 25 is being linked to the springs or groups of springs its end part projects and the head 10, in its first position, offers no resistance to its passage. The head carries a movable cutter 26 which co-operates with a fixed cutter 27 mounted on the sleeve 12. On rotation of the shaft the wire is trimmed and the end of the wire abuts the surface 28<SP>1</SP> of the head and an end portion also abuts a vertical surface of the cutter 26 so that the end is urged upwards by the rising surface 28<SP>1</SP> while the end portion is twisted backwards to form the loop shown in Fig. 5 as the shaft moves to the second position.
Patent GB-430578-A (GB)
Title: Hydroabietyl alcohols and their manufacture
Filed: 1933-12-21
Abstract: Hydroabietyl alcohols are prepared by reducing an ester of a hydroabietic acid, or a substance containing such an ester, with an active reducing metal in the presence of an alcohol and, if desired, a diluent and thereafter decomposing the resulting metallic derivative with water.  Dihydro- and tetrahydroabietyl alcohol may be so prepared.  Hydrogenated ester gum, obtained by esterifying hydrogenated rosin with glycerine, or the ethyl, propyl, butyl amyl, glyceryl or glycol esters of a hydroabietic acid may be employed as the initial material.  Sodium, potassium lithium or amalgams of active metals such as aluminium amalgam may be used as the reducing metal.  Ethyl, propyl, butyl, and amyl alcohols are referred to as suitable alcohols and xylene, benzene and toluene as suitable diluents.  After adding the water to decompose the metallic derivative, the reaction mass separates into two layers.  The upper layer is withdrawn and evaporated to dryness.  The hydroabietyl alcohol is obtained from the dry residue either by extraction with a solvent such as benzene at the boiling point or by distillation with superheated steam, say at 180--225 DEG  C., under a vacuum. Hydroabietyl alcohol may be reacted with organic acids or anhydrides to give the corresponding esters, for example, when heated with acetic anhydride it gives hydroabietyl acetate.  With hydroabietoyl chloride it forms hydroabietyl hydroabietate.  Examples are given.

Title: Angle measuring apparatus with digital output
IPC: G08C19/46
Filed: 1966-08-12
Abstract: 1,120,599. Selective signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 12 Aug., 1966 [19 Aug., 1965], No. 36146/66. Heading G4H. The outputs S1, S2 from a two-phase resolver, Fig. 1, are so combined, by phase shifting circuits, as to produce two signals 16, 17 which respectively lead and lag the phase of the reference signal applied to the resolver rotor by an amount proportional to the angular displacement of the resolver rotor from its reference position (equally inclined to both stator windings), and their phase difference is digitized by using their zero-crossovers to start and stop the counting of relatively high frequency clock pulses. The counter indication is held steady for a short period before being reset 250 times per second. A three-phase synchro followed by a Scott transformer could be used in place of the twophase resolver, and the output of the counter could be converted into an analogue voltage.

Title: Supercharged Internal Combustion Engines
Inventor: WOLF GOTTLIEB
IPC: F02B37/10
Filed: 1967-08-08
Abstract: 1,189,829. Supercharging I.C. engines; power plant. SULZER BROS Ltd. Aug. 8, 1967 [Sept. 9, 1966J, No.36414/67 Headings F1B and F1Q. In an I. C. engine a hydraulic positive displacement motor 10, Fig. 3 is coupled directly to the shaft 4 of an exhaust gas turbine-driven supercharger unit 2 by a non-releasable coupling 8 and a hydraulic pressure line 14 and an air line 43 are each connectable to the hydraulic motor inlet. Operation: Oil is delivered by an engine driven or electric motor driven pump 13 from a tank 17 through a transfer pump 30 to the hydraulic line 14. Pump 30 may supply the engine lubrication system through feed and return lines 31, 35. The connection of the hydraulic feed line 14, and the hydraulic return line 52 to hydraulic motor 10 is controlled by a spring-loaded spool valve 51 which moves in response to the air pressure existing in reservoir 7. At lower engine outputs the apparatus is in the position shown when the supercharger 2 derives additional power from the hydraulic motor 10 which discharges into line 52. During full load operation the supercharger 2 receives sufficient power from the engine exhaust gases and also drives the hydraulic motor 10 which then acts as a pump. The increased pressure in reservoir 7 acts on spool valve 51 which is moved to a position admitting only oil-laden air from the engine crankcase through line 43 to the hydraulic motor 10, which is thereby cooled, air being discharged from the hydraulic motor via line 53 to tank 17. In modifications valve 50 may be operated electromagnetically and line 52 may lead into the engine crank-case. When the pressure in reservoir 7 rises beyond a predetermined value a valve 34 is progressively opened by a servomotor 37 in response to the pressure rise communicated through line 38 to by-pass the oil delivery back to tank 17. Alternatively valve 34 is opened in dependence upon crank-shaft or supercharger speed or the pressure in line 14. In another embodiment the hydraulic and air return lines 52, 53 are replaced by a single hydraulic and/or air return line (15, Fig.2 not shown) which is not controlled by the spool valve and discharges directly into tank 17. In a further embodiment the spool valve 50 is omitted, the pump 13 feeds the hydraulic motor 10 directly and the air line 6 and hydraulic line 14 are interconnected by a relief valve (22, Fig.1 not shown). During full-load operation the pressure drops in the hydraulic line 14 and the increased pressure in line 6 causes the relief valve (22) to open thereby admitting air through the downstream part of the hydraulic line, to the hydraulic motor 4. When the engine slows down the pressure in line 6 drops, valve (22) closes and the motor 10 recommences to drive.
