Title: An improved apparatus for launching ships' lifeboats
IPC: B63B23/04
Filed: 1923-02-23
Abstract: 212,730. Crossley, J. Feb. 23, 1923. Boat-lowering gear.-Luffing-davits which with their load tend to move outboard under gravity, are provided with a triangular base terminating in inboard and outboard trunnion pins 51, 56 which co-operate with pillow blocks 52, 57 fixed to the deck. The stanchions 29 to which the davits are hung back by the lowering-tackle 33, have at their base panel plates 54, having arcuate slots 53 in which work the trunnion pins 51. In operation, the davit when fully inboard rests solely on the pillow 'block 52. When luffed outboard, the davit rotates about the trunnion 51 until the trunnion 56 rests in the pillow block 57. The davit then rotates about the pillow block 57 until fully outboard. The rope gear for controlling the swinging of the davits is separate from the boat fall gear and comprises a pair of adjacent drums 35, 36 about which the ropes 33, 37 are wound after passing round fairleads 31, 32 on davit and stanchion 29 respectively. The drums 35, 36 are simultaneously operated by gear comprising pinions 39, 40 worm wheel 42 and worm 43. When a heavy purchase is desired, the drum is applied to a large spur wheel 46 in gear with the worm 43. The chocking-gear comprises a channel section keel bearer 61 supported by brackets 60 secured to the davits and provided with pivoted latches 63 which secure the keel when turned to the operative position by means of the push bar 66. The inboard side of the boat is supported by bilge chocks 70, Fig 4, carried by levers 71 pivoted to the davit brackets 60 and linked to radial arms 74 provided with pawls 75 working on arcuate racks 76. The bilge chocks thus automatically rise to support the boat as the davits are luffed inboard. Associated with the keel bearer 61, are rails 98, supported by chains 97, these rails collapse when the davit moves outboard. A companion ladder 94 is also provided. The inboard and outward gripes 80, 85 are provided with slip hooks. The mechanical gear for controlling the boat pulls 24 consists of a winch drum 106, Fig. 10, controlled by a screw operated hand brake 107, the drum being operated by gear terminating in a worm 112 which by means of a screw 116 may be moved out of gear with its worm wheel when it is desired to control the lowering of the boat by the hand brake alone.

Title: Improvements in or relating to electric signal generators
IPC: H02K24/00
Filed: 1954-03-01
Abstract: 778,161. Electric signal generators. BENDIX AVIATION CORPORATION. March 1, 1954 [April 2, 1953], No. 5960/54. Class 40 (1). [Also in Group XXXV] In an electric signal generator with a stator member and a rotor member angularly movable in either sense from a reference position to generate a signal corresponding to relative displacement of the members, a part which is urged by resilient means towards a certain position is displaced in the same direction away from this position by an element on the rotor when the rotor moves in either sense, the resilient means thus tending to restore the rotor to its reference position. On the end of a rotor shaft 20 is secured a bifurcated bracket 50 carrying upstanding pins 56, 58. In the normal position of the shaft pin 56 and a bolt 60 threaded in pin 58 both engage the lever 51, which is pivoted on a pin mounted on plate 62 secured to the housing 12. When the shaft is displaced in a clockwise or anticlockwise direction, the pin 56 or bolt 58 respectively moves lever 51 against the tension of spring 52, the arrangement being such that when the torque on the shaft is released the shaft is returned to a unique position relative to the housing. This position may be altered by adjustment of bolt 60 in pin 56. The shaft 20 carried in ball bearings 26, 28 carries a winding 9 which rotates in the field of A.C. supplied fixed windings 8, and is normally so positioned relative to the field as to give zero output voltage. The signal from winding 9, the amplitude and phase sense of which depend respectively on the degree and direction of shaft rotation, is fed to conduit 33 via slip rings and collectors 36, 38.

Title: Particle counting system including a coincidence correction circuit
IPC: H03K21/02
Filed: 1975-02-13
Abstract: 1468332 Particle counting systems J T BAKER CHEMICAL CO 13 Feb 1975 [1 March 1974] 6086/75 Heading G1N In order to corrrect for errors caused by coincident passage of more than one particle through the aperture of a particle counter a circuit is provided including a memory store having data stored at different predetermined addresses representing predetermined values at which a corrective pulse is to be added to the measured count. Each pulse derived from the electrodes across the aperture of a conventional particle analyzer is applied to the inputs of one shot multi-vibrators 32, 34 multi-vibrator 32 being triggered on the trailing edge of a pulse whilst 34 is triggered on the leading edge. The output pulse from multi-vibrator 32 is fed to NOR gate 38, the output from which represents the count, and as a clockpulse to address register 36 consisting of three integrated circuit binary counters, Fig. 3 (not shown), which provides a multi-bit output signal corresponding at any time to the number  of clockpulses applied thereto. This output signal sequentially addresses a read only memory 44 in which is stored at different addresses data representative of the statistically determined values at which additional pulses must be added to the measured pulse count in order to compensate for the coincident passage of more than one particle through the aperture. If the address register addresses one of these addresses memory 44 provides a multi-bit output to multi-plexer 46 which decodes the output and applies a pulse to either gate 40 or 42 which when a pulse from multivibrator 34 is applied thereto applies a correction pulse to NOR gate 38 so that the output from this latter gate is the corrected count. When the circuit is employed for counting red or white blood cells each of which have a different coincidence error correction data for both sorts of cells is stored in memory 44 and multi-plexer 46 provides an output to one of the gates 40, 42 when the particle count reaches correction values for a red cell and to the other gate when it reaches the value for the white cells. Both these outputs are received by the gates regardless of which cells are being counted but only one of the gates is enabled by the "control" signal applied directly to one gate and via inverter 49 to the other gate to select the appropriate output from the multi-plexer.

Title: Improvements in Scavenging and Cooling the Cylinders of Internal Combustion Engines.
Inventor: RICARDO HARRY RALPH
IPC: F02F3/16
Filed: 1917-05-02
Abstract: 127,625. Ricardo, H. R. May 2, 1917. Two-stroke-cycle engines; exha.ust, coo.ing.- Cylinde s are scavenged with cooled combustion gases which are first exhausted through terminal ports and then re-admitted when the cylinder pressure is sufficiently reduced. Fig. 1 shows one of four cross-connected radial cylinders which compress combustible mixture in their closed ends adjacent the driving-shaft. Charges are admitted to the pump space M through a port M<1>, and are delivered to a cylinder head through a non-return valve K when a post C<2> in a piston registers with a cylinder port (not sbown). During the out-stroke of the piston, the combustion gases escape through terminal ports B, and also though ports D leading to a cooler F, the gases from which are forced back into the cylinder by compressed air supplied to a pipe G by a fan or blower (not shown). Single-cylinder engines, and engines in which an explosion acts upon two pistons simultaneously, are described in which the combustion gases in the cooler and an associated expansion chamber re-enter the cylinder under their own pressure, the air supply being dispensed with. Crank-case compression may be used for supplying the combustible charges.

Abstract: 484,622. Folding monoplane wings. FAIREY AVIATION CO., Ltd., LOBELLE, M. J. O., and TROTTER, J. C. March 2, 1937, No. 6210. [Class 4] In a low wing monoplane having foldable wings pivoted about vertical axes situated at the sides of the fuselage and between the leading edges of the wings, a part of the under surface of the fuselage is retractable so as to allow part of the wings when in their folded position to underlie the fuselage. As shown in Fig. 1, a wing 17 comprising a foldable trailing edge part 18 is hinged about axis 13 to a fuselage 19 and is shaped to engage a trapezoidal stub wing 30 about an oblique line. For folding the wing part 18 is folded downwardly and part of the fuselage under-surface is moved upwardly as shown in Fig. 3. The fuselage bottom is caused to retract either as shown in Fig. 5 wherein a bottom part 20 is pivoted at its rear end 21 and connected to the side walls by inwardly collapsing pivoted strips 23, 24, and swung upwardly by an hydraulic jack 22 or as shown in Fig. 7 in which a false bottom 25 is suspended by links 26 in such manner as to be capable of swinging rearwardly and upwardly to the position shown. Alternatively electrical power means may be employed. Wing swinging may be effected by hydraulic jacks 29, Fig. 1, supplied with fluid from a hand pump via a distributing valve permitting successive operation of the wings. A mechanical system described in connection with a float seaplane comprises a drum 33, Fig. 10, secured in stub wing 35 around which is wound a cable 34 of which the free end is attached to the edge of folding wing part 36. In drum 33 are disposed brake shoes 37 operable by hand lever 38. Drum 33 is provided with a winding handle. When a seaplane is hoisted out of the water the brakes are applied whilst the wing latch pins are removed, and are released to allow the wings to swing back under gravity, assuming the seaplane is in a tail-down position, and again applied to retard the final part of the folding movement. The stub wings may accommodate bombs or fuel tanks and may serve for mounting or stowage of alighting gear.
