Abstract: 125,003. Masterman, E. A. Aug. 14, 1918. Anchoring.-Lighter-than-air aircraft are moored to a mast by ropes attached to points symmetrically disposed on either side of the nose of the craft, the line joining the points preferably passing through the line of the resultant wind-pressure. As shown, the mast A has a crutch B fitted with winches C<1>. C<2> from which the mooring ropes extend to a pair of " Parseval ring " attachments J<1>, J<2> on the nose of the airship. A third Parseval ring " J<3> is provided for the attachment of a rope K fastened to a winch C<3> by which the craft is hauled into position for attaching the mooring ropes. The crutch may be of triangular girder form and may be mounted to rotate on the mast or, as shown, the mast may rotate with the crutch, being for this purpose mounted upon a ball-and-socket footstep bearing E, Fig. 5, and supported freely in a ring G to which the guys F are attached. To facilitate entrance of the nose of the craft into the crutch in rough weather, the mast may be swung about the bearing E or the crutch may be hinged to the mast so that the arms of the crutch may fall The mast may be of telescopic construction to permit of varying its height and in larger forms it may comprise two or more members carrying a platform on which is placed the mooring gear. The guy ropes may be dispensed with and the mast be designed as a cantilever pivoted at its lower end and provided with toothed segments engaged by gearing.

Title: Improved process of compounding fats and oils
IPC: A23D9/02
Filed: 1920-05-17
Abstract: A homogeneous nonliquating product is obtained by melting a "hard" fat, such as stearin, with preferably 3 to 6 times its weight of fluid vegetable oils, such as cotton-seed oil, soy-bean oil, or pea-nut oil, and cooling the melt slowly for at least thirty minutes with continual agitation from a temperature slightly above the melting-point of the hard fat to a temperature slightly below its point of crystallization.  The initial cooling may be rapid, but the final cooling, which in the case of stearin extends from 115-116 DEG F. to 90 DEG  F., should occupy 30-60 minutes. The process is facilitated by the addition of a small amount of the previously-formed congealed mixture, which acts as a starter, or by conducting the final cooling in a vessel already used for the purpose.  Natural or artificial products containing stearin may be used instead of stearin alone.

Abstract: 1,213,702. A/D converter. STANDARD TELEPHONES. & CABLES Ltd. 21 March, 1968, No. 13714/68. Heading G4H. In an analogue/digital converter of the type in which pulses f c  are counted in a counter 2 (Fig. 4) until equality occurs between a reference ramp signal and the analogue input, a phase displaced signal is derived from the signal f c  and fed via an AND gate 5 (controlled by comparator 1) to a bi-stable circuit 6, the state of the bi-stable circuit at the end of the count being read out to give an extra digit. Preferably the phase displaced signal is 180 degrees out of phase but two signals 120 degrees and 240 degrees out of phase may be used. The counter is read out in parallel to a shift register, the contents of which may be transmitted together with the extra digit to a receiver system for conversion back to analogue form. The digital/analogue converter comprises a shift register (17, Fig. 5, not shown) connected to a counter (8) which is counted down to zero by either the signal f c  or signal f c  in accordance with the value of the transmitted extra digit which enables one of two AND gates (13, 14, Fig. 6, not shown) to pass either f c  or f c  respectively. A ramp generator (9, Fig. 5, not shown) is enabled at the start of the decoding period, a hold circuit (10) being activated when counter (8) reaches zero.

Title: Improvements in windscreen wipers
IPC: B60S1/10
Filed: 1957-04-30
Abstract: 865,968. Windscreen wiper motors. TRICO PRODUCTS CORPORATION. April 30, 1957 [April 30, 1956], No. 13730/57. Class 138(1). A compressed air operated windscreen wiper motor comprises a manual control valve movable between an " operating " position in which a distribution valve supplies compressed air to opposite sides of an oscillating piston, and a " parking " position in which the distribution valve transmits compressed air to one side of the piston to park it beyond the limit of oscillation, the pressure on the two sides of the piston being balanced after parking. As shown, the supply of compressed air from threaded recess 62 is permanently connected to chamber 42 via passageway 64, needle valve chamber 66, and passageway 68. When arm 34 rotates shaft 51 and connected valve 48 to the position shown in Fig. 7, holes and grooves mate in such a way that compressed air flows from chamber 42 into distribution valve chamber 38 and through passage 93, out of port hole 89, into groove 78, port hole 82,-passage 83, and to the left side of piston 99. Meanwhile the other side of the piston is connected via parking chamber 88, passage 87, port hole 86, groove 77, port hole 92, passage 96, groove 110, passages 106, 107, and conduit 108 to atmosphere. When the piston nears the end of its stroke, arm 102 engages stop 105 and shifts shuttle 103 counterclockwise and air pressure in chamber 38 moves distribution valve 104 to the position shown in Fig. 8 in which air pressure is applied to the opposite side of the piston. When arm 34 is moved to the " parking " position the piston is moved into contact with the parking chamber 88. When the vehicle operator releases the control knob, spring 54 rotates parking valve 48 clockwise to the " parked " position between the " operating " and " parked " positions in which compressed air is no longer applied to the left of the piston, while excess air pressure on that side is reduced by leakage around the piston. In the embodiment shown in Fig. 15, a slidable spool valve 138 replaces distribution valve 104.
