Title: Improvements in submarine signaling systems
IPC: G01S1/72
Filed: 1944-06-30
Abstract: 631,519. Locating sounds. SUBMARINE SIGNAL CO. June 30, 1944, No. 12540. Convention date, April 26, 1940. [Class 118 (ii)] A directional submarine sound detector comprises several pick-up units with beam axes in selected directions and having a combined beam pattern affording substantially uniform sensitivity throughout the sector covered, each unit having an electrical circuit which may be selectively tuned to the frequency of the sound received, the tuning members being coupled with a displacement in tuning between each circuit corresponding to the angular spacing of the beam axes; a receiver operates listening or indicating means in order that the sound direction may be determined in accordance with the position of the tuning members at which maximum combined output is observed. The system shown comprises Rochelle salt transmitting and receiving units 9, 5, 6, 7 and 8, arranged as described in Specification 604,358, each having a beam pattern with an angular opening of 120 degrees, the beams being overlapped to give a substantially uniform combined intensity of emission and reception in all directions except aft, the units being connected in parallel by the multiple pole switch 26, and, through the contacts 34, 35, in series with the receiver 22, so that an original or reflected sound within the range of the detector .will produce a signal audible in the head-set 24 or visible in the neon tube indicator 25. To emit a signal, the key 30 is manually or automatically depressed to establish connection with the power source 20 through a switch 31, contacts 34, 35 simultaneously disconnecting the receiver 22. For ranging, the switch 31 is opened, a switch 36 is closed, and the key 30 is held depressed, the emission of pulses then being controlled by the sending contacts of the distance indicator 21 (e.g. of the type described in Specification 309,901, [Class 118 (ii)], to which the echo pulse is applied by the receiver 22 through leads 38. For direction-finding, the switch 31 is closed, switch 36 is opened, and key 30 is depressed to emit a signal terminated by the manual or automatic movement of switch 26 to the right, whereby the units 9, 5, 6, 7 and 8 are disconnected from the power source 20 and connected to the receiver 22 through tuning condensers 45, 46, 47, 48, and 49, respectively, and their associated series-connected transformers. The condensers, displaced in phase as shown, and the indicator 25, are all rotated by the knob 43 to time the units 9, 5, 6, 7 and 8 in turn to the frequency of the emitted signal, and the required bearing is determined by the position of the indicator 25 relative to the scale 50 at which its indications, or the audible signals in the head-set 24, are most intense. For automatic actuation of the switch 26, a solenoid 62 may be energized by a time delay relay 59 operated through contacts 60 when the key 30 is depressed.

Title: Means for reducing starting torque in 4-cycle engines
IPC: F01L13/08
Filed: 1966-03-22
Abstract: 1,089,602. Reducing starting torque. BRIGGS & STRATTON CORPORATION. March 22, 1966 [March 25, 1965], No. 12560/66. Heading F1K. A four-stroke cycle internal-combustion engine has means at all times operatively associated with one of the valves and the actuating means for the same by which the actuating means is rendered ineffective to affect the position of the valve whenever during a predetermined portion of the engine cycle in which the piston is moving through a medial portion of a stroke the valve is less than a predetermined small distance from its seat so that during the portion of the engine cycle, the valve can respond to differences between pressure in its manifold and pressure in the cylinder to assume either a slightly open or a fully closed position whereby the valve is rendered effective to significantly reduce any unbalance of pressure on the piston which retards the same during starting of the engine without substantially interfering with normal pressure relationships which obtain in the cylinder during running of the engine. As the cam moves towards its power stroke position and permits the inlet valve 9 to come to a predetermined small distance from its seat, the force transmitting member bottoms on the abutment surface 22 so that the spring no longer maintains the valve in following relation to the cam 10. Hence when the cam is in its power stroke position the valve is free to move through that small distance toward and away from its seat in response to gas pressure forces on its head. A small spring 24 at all times lightly biases the valve 9 towards its closed position. The cam 10 is formed according to Patent 948, 477. The invention could as well be applied to the exhaust valve. In Fig. 4 (not shown) the cam 10' is completely conventional. The spring 13 is effective to apply a strong downward biasing force to the force transmitting member but there is a lost motion connection between the valve and the force transmitting member. When the cam is in positions at which it does not Impact lift to the valve, the valve is movable to and from its seat by a small distance. A light spring 124 urges the valve away from its closed position. Alternative locations of the light spring are disclosed. In another modification the light spring is omitted and the cam 10 has a feature of Specification 948, 477, utilized to hold the valve 9 spaced a small distance from its closed position during a substantial portion of the compression stroke. In a still further modification the intake valve is arranged according to Patent 948, 477 while relief of suction during an unfired combustion stroke is provided for by applying the present invention to the exhaust valve. In yet another modification the cam is cut down below its base circle radius by about 0.010 in. through its power and exhaust stroke portions. The valve is lightly biased away from its seat to hold it open about 0À010 in. during compression when the engine is being started.

Title: Improvements in or relating to crop drying systems
IPC: F26B21/00
Filed: 1970-03-16
Abstract: 1299403 Crop drying system TEXAS INDUSTRIES Inc 16 March 1970 [19 March 1969] 12599/70 Heading F4G [Also in Division B8] In a crop drying system, crop is gathered from the ground using a pick-up mechanism 4, Fig. 2, which forms part of a trailer 1A, 1B, and is fed into a chamber in the trailer where it is dried using a drying unit 11 mounted on a tractor 10, a plurality of such trailers being connected simultaneously to the drying unit. Pick-up mechanism.-The pick-up mechanism Fig. 3, comprises a rotary tine assembly 23, feeding a channel 26 formed in the trailer between wall members 27, 28, 29 and 30 and which is provided with two feeding mechanisms 37, 48. The lower mechanism 37 comprises tines 35 mounted on a driven pinion 38, with arms 35A fixed, via linkage 41, to the wall 43 of the trailer such that on rotation of the pinion 38 the tines 35 execute a kidney shaped path 36, and force the crop up the channel 26. The crop is then engaged by the second mechanism 48 in which teeth 52, 53 and 54 are mounted on a member 49A, the teeth projecting through the wall 28 into the channel 26. The lower end of member 49A is pivotably connected to the pinion 38, the upper end being held against wall 28 by spring 55, such that on rotation of the pinion 38 the teeth move within the channel 26 on the upward stroke of member 49A but are at least partially withdrawn from the channel on the downward stroke, causing the crop to move up the channel 26 until it falls over the wall 27 into the chamber 56. Drying unit.-The drying unit comprises a burner 20, Fig. 2, communicating with each vehicle 1A, 1B via blowers 15, 16, the unit being mounted on the three point linkages 9 of a tractor 10, with the blowers and burner being driven from the power take-off 13 of the tractor. The air may be fed into a channel 70, Fig. 5, in the lower portion of the chamber 56, the walls of which are covered in heat insulating material 59, and passes through holes 63 in the floor 32 of the chamber, through the crop, located on an endless conveyer 61 in the chamber, and passes out of the chamber through orifices between the walls of the chamber and the roof 66. The unit may be used with the burners inoperative i.e. to blow cool air through the crop, with valves (81), Fig. 7 (not shown), being used to control the flow of cold air, and the conveyer used to discharge the crop from the chamber e.g. to a storage area.

Filed: 1963-03-29
Abstract: 991,990. Disc brakes. BENDIX CORPORATION. March 29, 1963 [April 13, 1962], No. 12659/63. Heading F2E. In a disc brake for a vehicle a caliper housing 10 straddling a rotatable disc 11 is mounted on a stationary support 12 so as to be rockable relative thereto about axes A-A and B-B arranged at 90 degrees to each other and parallel to the disc faces and to be slidable relative thereto parallel to the disc axis. The support is disposed on one side of the disc and bolted at 17 to a stationary vehicle part. As shown, arms 16 project from the support and have threaded therein bolts 18 having trunnion portions 20 on which bearing members 22 are pivoted. Each member 22 has a flat-sided transverse tongue 26 engaging a slot 30 in a caliper housing boss 28. The slot 30 extends perpendicularly of the disc faces and has a bottom surface 34 convexly shaped to an arc of radius R. The members 22 are axially adjustable by rotation of the bolts 18. Boots 36 attached to the bosses 28 and between flanges on the members 22 and the arm 16 prevent loss of lubricant and entry of contaminants. The caliper housing carries brake pads 42, 44 arranged on opposite sides of the disc 11. The pad 42 comprises a pair of friction linings 50 on a backing plate 46 bolted to legs 54 of the caliper housing. The pad 44 comprising a single friction lining 52 arranged, on a backing plate 48, offset between the linings 50, is acted on by an hydraulically actuated piston 70 in a chamber 68 of the caliper housing, and is guided by rods 60 which are retained in the caliper housing by pins 66 and extend through openings 58 in the plate 48. In Figs. 6, 7 (not shown) the bearing members pivot on trunnion bosses on the caliper housing and their flat-sided transverse tongues have convex ends and engage slots in members bolted to the support arms.

Title: Signal processing stage
IPC: H04N5/10
Filed: 1971-05-03
Abstract: 1389202 Television; automatic gain control RCA CORPORATION 1 May 1972 [3 May 1971] 12667/71 Headings H4F and H3T Video demodulation, automatic gain control voltage generation, horizontal synchronizing pulse separation, and vertical synchronizing pulse separation are all effected by the circuit shown in Fig. 1, by taking into account the mutual dependency that exists between the amplitude of the synchronizing pulses in the television receiver and the AGC voltage developed, and also the fact that the amplitudes of the black level and gain control voltages at the video demodulator are substantially equal. The IF composite video signal across the secondary of the IF output transformer 34 is demodulated by rectifier 32 having a load circuit 38, 40, but during horizontal blanking periods transistor 10 is driven to saturation by horizontal flyback pulses applied at terminal 12 causing the anode of rectifier 32 to be coupled to ground which places in parallel with load circuit 38, 40 a further load circuit 42, 44 of smaller impedance, i.e. the essential load of the demodulator is provided by 42, 44 during the horizontal flyback periods. Thus the polarity of the rectifier 32 is effectively reversed so that the video component of the composite signal is derived at output terminal 14, this component being clamped to ground, and the horizontal synchronizing pulse component at output terminal 24. An AGC voltage is also developed at output 24 and vertical synchronizing pulses are derived at output 20 with the AGC voltage amplitude. Specifically capacitor 42 is charged by the horizontal synchronizing pulses to the AGC voltage, resistor 44 determining the time constant of the charging operation such that the pedestal of the AGC voltage is substantially equal to the black level amplitude of the IF envelope. The AGC voltage is added to the video output at terminal 14 so that the black level of the output video signal is fixed. In colour television receivers the horizontal pulses applied to terminal 12 are narrowed to avoid blanking the burst interval.

Title: Improvements in or relating to Machines for Producing Curved Stereotype Printing Plates.
IPC: B41D3/00
Filed: 1916-09-07
Abstract: 109,307. Printing Machinery Co., (Wood, H. A. W.). Sept. 7, 1916. Printing-surfaces; stereotype.-In a machine for casting and finishing curved stereotype plates, the plates are automatically and positively transferred from a vertical casting-apparatus to the finishing- apparatus by power-operated means between the casting and the finishing apparatus. As shown, the plates are cast between a vertical core C and movable back B and finished in an inclined finishing apparatus F. This core C is rotated on its axis through 180 degrees after each cast, to bring the cast plate opposite to a swinging frame comprising a pair of bent arms 170, Figs. 1, 5, and 6, pivoted on studs 171 adjacent to the top of the core C and connected by links 173 to cranks 175 on a power-driven shaft 27. Each arm 170 is provided with a bracket 178 to engage under the lower end of the plate, and with two slidable plates 176 adapted to engage behind the vertical edges of the plate and, during the swing of the arms away from the core, to strip the plate from the core and carry it into alinement with the finishing- apparatus F. The plates 176 are secured to blocks 184 connected by links 182 to arms 181 fixed to a shaft 180 provided with a spring 188 normally holding the plates 176 in position to engage the cast plates P, as shown in Fig. 6. When the frame swings towards the core, cams 177 on the links 173 engage rollers 179 and turn the shafts 180 to withdraw the plates 176 until they have passed the plate P, when they are released and return to plate-engaging position. The core is provided with arcuate grooves c<2>, Fig. 2, concentric with the pivots 171 of the swinging frame and adapted to cast projections on the plate adapted to slide in the grooves c<2> during the swinging of the frame away from the core and thus to guide the plate. The plate is delivered from the frame to supporting-arms 210, 211, Figs. 2 and 3, in alinement with the finishing-apparatus. These arms are secured to shafts 212 provided with springs 214 adapted to press the arms normally towards each other to an extent limited by the engagement of stops 215 on the shafts with the brackets 213 supporting the shafts. The arms 211 have feet provided with inclined portions adapted to be engaged by the tail of the plate when the frame 170 swings away from the core, so as to separate the arms 210, 211 against the action of the springs 214 to allow of the passage of the plate without contact of the printing-surface of the plate with the arms 210. When the plate is above the lower inturned ends of the arms, the arms swing back to support the plate, as shown in Fig. 3. When the frame 170 swings back towards the core, the plate slides off the arms 210, 211 into the finishing-apparatus.
