Title: Improvements in carburetters for internal combustion engines
IPC: F02M21/00
Filed: 1935-01-01
Abstract: 436,564. Starting carburetters. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot, Geneva, Switzerland. Jan. 1, 1935, No. 101. Convention date, Jan. 4, 1934. [Class 7 (iii)] A valve controlling a mixture outlet from a starting carburetter to a main mixing tube and a valve controlling an air intake for the carburetter are controlled thermostatically, in response to the temperature of the engine only, the first valve being closed gradually as the temperature rises, while the second valve is opened to weaken gradually the mixture supplied to the engine. A casing 22 mounted on the exhaust pipe 21 houses an expansible box 23 yieldingly secured by a spring 27 and lock-nuts 25, 26 to one end of the casing. A lighter spring 31 operates against the opposite end of the box 23 which carries a rod 29 having its outer end adjacent a bell-crank lever 34. As the engine warms up, expansion of the box 23 displaces the rod 29 outwards, rocking the lever 34, which is connected by a rod 36 to a lever 16 rigid with the throttle valve 9 of a starting carburetter 6, to close the valve 9. Simultaneously, an air choke valve 11 in the starting carburetter, connected by an arm 17 and link 20 to the lever 16 is moved towards the open position, the proportion of fuel in the mixture formed being thereby reduced as the throttle valve is closed by the heating of the engine. A screw 19 adjusts the minimum opening of the air valve 11. Instead of actuating the air valve 11, the throttle lever 16 may be formed with a cam which controls a spring- pressed plunger adapted to regulate the admission of air to the fuel feed pipe 13 to supplement that normally drawn through an orifice 15 to aerate the fuel. In a further modification, a submerged jet is used and the aerating air is drawn from the top of the float chamber. As shown in Fig. 6, a throttle valve 41 controlling a mixture passage 40 is formed with a stem 42 carried by the end of an expansible box 43. The box is housed in an apertured casing 44 which may be disposed near the engine in the bonnet or adjacent the exhaust pipe. A suction actuated valve 52 closed by a spring 53 slides on the valve stem 42 to control an air inlet 50. On an increase of temperature, the box 43 moves the throttle valve 41 towards its closed position and closure of the air valve 52 under the reduced suction is prevented by a shoulder 54 on the stem 42, the mixture provided being thus weakened with increasing temperature. A further shoulder 57 on the stem 42 may limit the maximum opening of the air valve 52. In another form, the air valve is independent of the throttle valve, the stem of which uncovers aerating ports in the fuel passage as the valve closes.

Filed: 1933-01-03
Abstract: 402,606. Setting press-button eyelets in caps. STOCKO-METALLWARENFABRIKEN GES., 2, Kirberg, Elberfeld, Wuppertal, Germany. Jan. 3, 1933, No. 174. Convention date, June 14, 1932. [Class 43.] A machine for setting press-button eyelets x with caps y in gloves or similar material S comprises an upper vertically reciprocable stamp 12 adapted to upset the eyelets in caps held in a lower die 16, and a spike 9 adapted to move upwards from the lower part of the machine and pierce the material S clamped by a ring 10 on a support 7. The spike, after perforating the material, moves up further and enters an eyelet at the bottom of a movable shoot 18 which is then moved so as to strip the eyelet from the shoot. The stamp 12 then moves down with the point of the spike seated in an axial bore of a pin 13 spring- mounted in the stamp. The eyelet is thereby introduced in the hole formed in the material and the spike moves further down so that the lower die 16, carrying a cap, can slide under the eyelet, Fig. 6. The ring 10 is then raised and the stamp 12 moved further down to complete the setting operation. The lower die may be fixed and the spike operate through an aperture therein. Hopper and delivery raceways.-The shoot 18 may be pivoted for movement away from the spike. The eyelets are delivered from a hopper 19 by a rotary brush 30. The caps may be delivered direct or by a slide to the die 16, but where this die is formed by a recess in a slide 17 for feeding the caps, these may be delivered from a hopper 21 by a shoot 20 to a guide 22 arranged over the slide 17. The caps are engaged by hooks 32 carried on a rotary wheel 31 and are thus fed to the mouth of the shoot 20. The caps are then fed along the guide in a column by a dog 27, Fig. 3, moving with the slide 17 and forcing the column along so as to push the first cap past spring- pivoted pawls 24 into a stop 23. The pawls may be pushed apart by cams 26. On rearward movement of the slide, the cap in the stop 23 drops into the die recess 16 and simultaneously the dog 27 uncovers the shoot opening to allow a further cap to enter the guide.

Filed: 1971-01-04
Abstract: 1380914 Diaphragms; moving coil transducers ROLA CELESTION Ltd 30 Dec 1971 [4 Jan 1971] 331/71 Heading H4J A loud-speaker or other electro-acoustic transducer has a diaphragm comprising a resilient self-sustaining dome 26 and a separately formed surround 28. The dome is made by coating a soft woven fabric with epoxy resin, heating and pressing in a die to the required dome shape and then treating with a plastics material which is unaffected by climatic conditions, e.g. heat and dampness. The surround 28 is clamped between rubber washers 24 at its periphery and has a corrugated portion and an inclined portion (see Fig. 2A, not shown). The inclined portion is glued or cemented to the dome 26. The surround 28 is made from linen impregnated with incompletely cured phenol formaldehyde resin. The corrugated portion is formed during a heating and pressing operation which also hardens the resin. The dome 26 and surround 28 are impervious to air. The voice coil 30 is mounted on a cylindrical epoxy resin coated paper tube and is secured to the dome 26 and surround 28 by glue or cement. The loud-speaker shown is of the "mid range" type and comprises an annular front plate 10 behind which fits an annular strip 14 of synthetic material. Behind a protective grill are a pair of insulating washers 18 and between the washers 18 pass beryllium strips 20 (see also Fig. 2A, not shown) which connect the voice coil 30 to tags 33.

Title: Teat cups for milking systems and to such milking systems
IPC: A01J5/04
Filed: 1972-01-05
Abstract: 1385511 Milking systems ZERO MFG CO 5 Jan 1972 [24 June 1971] 360/72 Heading AIM A dual vacuum milking system comprises claw and teat cup assemblies constructed to facilitate washing and draining without disassembly, and is such that optionally either the whole milking system or individual teat cup and claw assemblies can be cleaned. Each teat cup has a flexible inflation 105 with a flange 107 foldable over the rim 108 of the associated shell 103A during milking to close a groove 105A in the side wall of the inflation. After milking the flange 107 is unfolded to uncover the groove 105A which provides a passage to the space between the shell and the inflation. During milking vacuum pulses are supplied by a pulsator 360 to the annular teat cup space by way of lines 123, 119, and a constant vacuum is applied to milk conduits 115 by way of a line 125. The milk is withdrawn from the claw receiver 117A through a line 128 under a relatively high vacuum and delivered to a tank 301 via lines 336, 332. To release the teat cups from a cow a valve member 140 is pulled outwardly, closing the vacuum line 125 and opening a hole 141 in the receiver 117A. A float valve 135 closes the milk line 128 and air enters the receiver, removing the vacuum from the teat cups so that they are released. To wash an individual assembly, the assembly is inverted as shown in Fig. 1, the flanges 107 are unfolded and the shells positioned in the washing/rinsing solutions. Valve 140 is then operated to close hole 141 and open low vacuum line 125. Valve 135 is held closed by the high vacuum in line 128. The solution is drawn into the teat cups, and is drained therefrom on operating the valve 140 to allow entry of air into the receiver 117A. In order to wash the milking system, the pipe 332 is uncoupled from the bulk collection tank 301 and is coupled to a manifold 334. The outlets from high vacuum line 336 and low vacuum line 338 are closed by valves and the milk line 128 and pulsator line of each assembly are connected to the manifold. Each assembly, with the inflation flanges unfolded, is inverted on racks 133 with their shells in the solution in a sink 342. A normally closed valve 339 is opened to connect lines 336, 338, and relatively low vacuum circulates the solution through the assemblies, pipes 332, 336 and 338 to a wash jug 328. When the jug is half full a timer operates to allow the solution to drain to the sink.

Abstract: 558,578. Testing television apparatus. STANDARD TELEPHONES & CABLES, Ltd. Jan. 8, 1943, No. 379. Convention date, Jan. 14, 1942. [Class 40 (iii)] A synchronizing generator for testing television apparatus comprising means for generating line and frame scanning signals, means for adjusting the frequency of the said signals, and means for adding to said signals uniformly timed pulses serving to test the scanning linearity of the television apparatus. In the arrangement shown in Fig. 3, a master generator 20 generates a 31.5 kc. sine wave and feeds it to a master oscillator 24 producing pulses of the same frequency. These master pulses are fed to a second oscillator 25 producing pulses at half the frequency, namely at 15,750 per second for line scanning. The master pulses are also fed to a chain of frequency dividers 30 ... 33 which divide the frequency successively by 7, 5, 5 and 3 yielding ultimately pulses at 60 per second. These pulses are fed back to an interlocking circuit 22, which is connected to a main A.C. supply at 60 cycles per second and serves to operate a circuit 21 to stabilize the frequency of the master generator 20, for example as described in Specification 554,588. The oscillators 24, 25 and the dividers 30 ... 33 may be relaxation oscillators of the kind shown in Fig. 1, the several switches 8 serving to adjust the frequencies being all mechanically ganged together. Outputs from the circuits of Fig. 3 are supplied to a mixing chain of circuits, Fig. 4. The line frequency pulses from the generator 25 are fed to a carrier wave generator 41 and to a shaping device 42. The carrier wave from generator 41 is fed to a keying circuit 44 controlling a mixer 47 between the shaping devices 42, 53. The keying circuit 44 is controlled by the pulses at 60 cycles per second from the last divider 33. In addition to these parts, which resemble the arrangement of Fig. 3 of Specification 542,258, the carrier wave output from generator 41 may be applied to the mixer 47 through resistance 49 and switch 48, and the output from the divider 31 may also be fed to the mixer through lead 54 and switch 52. If the output of the final shaping device 53 is fed to a television cathode-ray tube, the pattern indicated by Fig. 5 is produced. The pulses due to the connections between generator 41 and mixer 47 through switch 48 produce the striations 59, 60 ; and the pulses from the divider 31, which includes harmonics of the fundamental, produce the alternate scale-like markings 65, 66. The correctness of these striations and markings indicate correct linearity of the scanning circuits.
