Title: A substitute for rubber
IPC: C08L97/00
Filed: 1937-05-20
Abstract: 501,267. Fibrous compositions. FALLS, D., and TABOR, G. J. H. May 20, 1937, No. 11198. [Class 70] A composition suitable for use as a rubber substitute consists of peat, slate dust (fullersite), glue, formaldehyde, and tar. Suitable proportions are 30 oz. of peat, 10 oz. of slat dust, 16 oz. of glue, 6oz. of dilute formaldehyde solution, and 2 oz. of tar. This is boiled until the mass becomes viscous, when it is poured into moulds and cooled. Sudden chilling produces a tougher, less resilient body. U.S.A. Specification 1,833,941 is referred to.

Abstract: 815,945. Jib cranes. ORENSTEIN-KOPPEL UND LUBECKER MASCHINENBAU A.G. April 5, 1957 [April 28, 1956], No. 11243/57. Class 78 (4). The winch plate 1 of a mobile crane can be tilted forwardly, together with the trestle 2 from which the jib is supported, to the position shown in Fig. 1 in which the raised end of the winch plate serves to support means for removing the motor unit of the crane. To effect the tilting the jib 4 is lowered to engage the ground and a line 13 is secured at 15 to the ground and passed over a jib end pulley to be secured at 14 to the trestle 2. The end 7 of the winch plate is then disconnected from the chassis and the crane is driven forwardly so that the rope 13 tilts the trestle 2 and winch plate 1 about a hinge 8 until it comes into engagement with a stop 12 previously secured to the jib. A laterally extending track beam is then secured to the end 4 of the winch plate to carry a carriage provided with tackle for removing the motor unit 9. The motor unit may provide for all the motions, including travelling, of the crane.

Title: Apparatus for automatically regulating the collective adjustment of the blade angle in a helicopter rotor
IPC: B64C27/54
Filed: 1962-03-27
Abstract: 981,240. Helicopters. DORNIER-WERKE G.m.b.H. March 27, 1962 [March 29, 1961], No. 11579/62. Headings B7G and B7W. A helicopter having a rotor driven by gaseous reaction propulsion and provided with collective pitch adjusting mechanism has the rotor head formed as a piston and cylinder in which pressure gas for driving the blades is used also to operate the piston to automatically adjust the collective pitch of the blades. The rotor head comprises a fixed portion 1 and an axially movable part 2 formed with cylindrical lands 12, 13 and sealing rings 16 to co-operate with corresponding faces on portion 1, the part 2 being movable manually by a collective pitch control lever 9. A cyclic pitch control lever 6 and associated spider 8 are mounted in part 2 by ball joints 5 and 7. Rotor blades (not shown) are attached to the hub by flat leaf springs and tip propulsion nozzles are supplied with pressure gas passed through the rotor head at 3 and 4. The wall of portion 1 is formed with ports 15 at its lower end and ports (not shown) may be formed in its upper end and with atmospheric vents 17. In operation, an increase in the supply of pressure gas to the rotor blades automatically forces piston part 2 downwardly with a consequential increase in the collective pitch of the rotor blades, against the restoring force created by twisting of the leaf springs attaching the blades to the hub. Upon a reduction of gas supply the springs return the blades to fine pitch. The automatic control may be overridden by manual operation of the lever 9.

A fluid flow selector valve for connecting a pressurized inlet 23 to one of a plurality of outlets (Nos. 3 and 6 of which are shown) has a bar 29 with an internal passage 33 keyed to a handle 19 by a pin 44 which is provided with a head 47 received in one of a plurality of recesses 48 so that the handle has to be moved axially inwards, moving valve closure member 34 to close the inlet 23 and connect the passageway 33 to the exhausted chamber interior 37, before the bar can be rotated to communicate the passage 33 with another outlet. The handle may only be moved axially to communicate the inlet with the passageway 33 again if the head 47 is opposite a recess 48 which corresponds with the spring-loaded sleeve 39 terminating passageway 33 being opposite an outlet. The outlets not communicating with the passageway 33 communicate with the chamber interior 37 which is exhausted through passageway 42, 43. The movement of the bar may be controlled by a one-way clutch and may be limited by a pin moving in a slot.

Abstract: 700,451. Electric coils transformers. STRONG, H. V., and EISLER, P. June 21, 1948 [May 3, 1947], No. 12001/47. Classes 35 and 38 (2). [Also in Group XXXVI] Coils or winding assemblies which may be for inductances, resistances, transformers or other purposes are formed by simultaneously winding or folding sheets of conductive and insulating material on to a former, preventing unwinding by further turns of one material or by a preformed cover and transversely cutting the roll to provide a plurality of coils or windings. Instead of separate sheets of conductor and insulation a fabric may be used consisting of strands of insulation running parallel to the axis of the coil and strands of conductor perpendicular thereto. Additional insulation in sheet form may be used with this modification if desired. As shown, copper foil 3 and polyethylene film or glass fibre cloth or wax impregnated paper 2 are wound on to a mandrel 1 of severable material or a collapsible mandrel and heat may be applied to bond the metal and insulation, and the end of the last turn is secured by adhesive or soldering, or a rigid tube of metal or insulation may be drawn over the roll before slicing. As a further alternative a rubber tube may be drawn over the roll or slice. If it be desired that the conductor and insulation are not axially coextensive, the sheet of conductor may be split into spaced but side-by-side strips or slots may be cut in it in the regions where slicing is to occur. There may be two or more insulating sheets for each sheet of conductor, or in the case of a transformer, two separate sheets of conducting material can be wound on simultaneously. Specifications 567,319, 639,111, 639,178 and 639,179, [Group XXXVI], are referred to.

Abstract: 379,654. Mechanical toys. WEILL, A., 30, Bauerngasse, Nuremberg, Germany. April 26, 1932, No. 12011. Convention date, July 30, 1931. [Class 132 (iii).] A surprise toy comprises a knob that projects from a two-part casing and upon depression releases a lever to cause the casing to vibrate. As shown, the casing comprises two flanged discs a, b relatively rotatable about a spindle c to stress a spiral spring e. A toothed wheel g rotated by the. spring co-operates with pallets q on a weighted lever o to vibrate the latter about its pivot p. The weighted lever is normally held against vibration by a lever that is urged into engagement with the weighted lever by a spring n. Upon the depression of a knob h carried by an arm i of the lever l, the weighted lever is freed to vibrate the casing. One method of using the toy is to hold the casing in the palm of the hand with a loop d passing over one finger, the knob being depressed by a second person when given a handshake. The surprise effect is increased by the noise created by the device when set in operation.
