Title: Improvements in or relating to electric control circuits
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: H04N5/228
Filed: 1951-05-31
Abstract: 702,169. Television transmitters. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 14, 1952 [May 31, 1951], No. 12809/51. Class 40 (3). [Also in Group XXXVIII] In a television transmitter as described in Specification 696,362 wherein blanking pulses generated at a control unit are transmitted through a cable to a camera unit to blank periodically the electron beam thereof, the blanking pulses being of adjustable amplitude to enable control of the electron beam current to be effected from the control unit, a limiter circuit is provided at the camera unit, the limiting level being varied in accordance with the amplitude of the blanking pulses. By this means hum and other interference is removed from the control signals, while their amplitude still corresponds to that established at the control unit. The incoming blanking and control pulses 5 are inverted by valve 13, the negative peaks then being set to a predetermined level by level-setting diode 16. The intervening positive-going portions are limited by diodes 21 and 26 to remove interference ; the limiting level is however controlled by the integrated current passing through the diode 16 by means of the resistance-capacitance circuit 22, 23, so that the signal applied to the control grid of the camera tube 7 varies in accordance with the amplitude of the control pulses 5.

Title: Mobile apparatus for baling automobiles
IPC: B30B9/32
Filed: 1960-04-11
Abstract: 947,519. Consolidating scrap metal; shearing. J. H. DUNLOP. (G. Maddox). April 11, 1960, No. 12927/60. Headings B3H and B3W. [Also in Division B5] Car bodies are baled for scrap in apparatus mounted for mobility, by being crushed in sequence in three directions at right angles. The apparatus may also operate on scrap &c. The apparatus may be mounted on a trailer 30 and comprises opposed walls 70, 72 hinged to a platform 50 at their lower edges and movable towards one another by hydraulic rams 86, 88. The upper edges carry shearing blades 100, 102. A car body 104 is positioned by a derrick 36 with its length transverse to the trailer and chassis 106 uppermost, the body then lying between the plates in their open position of Fig. 7. The plates are brought parallel to each other by the rams, crushing the  body longitudinally and shearing it away from the chassis. Detachment of the chassis is facilitated by bars 108, 112 movable vertically by rams 110, 114. The plates open slightly to allow the body to drop to the platform 50 and close again, latches (Fig. 11, not shown) retaining them in parallel position. Plates 132, 134 swinging about axes 176 transverse to the trailer, are operated by rams 146, 178 to compress the body against the platform, these plates being finally locked in horizontal position by bolts extended by hydraulic cylinders 188 into apertures in the plates 70, 72 (Figs. 6, 10). Final compression along the trailer length is then carried out by a ram 210 advanced by cylinders 212. The plates 70, 72 and 132, 134 now return to their original position and a telescoping ram 248 mounted on a plate 220 pivoted in the platform 50 (Fig. 17) raises the bale 217 to a door 254 forming part of the plate 70 which pivots open to serve as a discharge shoot. Means is provided to lubricate the surfaces of the plates 70, 72, 132, 134. In an alternative form (Figs. 23, 24, not shown), the shear blades are wider and are hinged to the plates 70, 72 so that shearing may commence earlier in the compression stage, and the blades may pivot upwards during the final movement of the plates. A retractable table 40 capable of being erected to one side of the trailer (Figs. 1, 3) carries an hydraulically operated shears for cutting the chassis into convenient sections. The shears may have two cutting edges 402, 404 at right angles to render less movement of the chassis 106 necessary during cutting. A winch 30 for pulling cars to the baler is provided.

Title: Improvements in the swell actions of organs
IPC: G10B3/16
Filed: 1921-05-07
Abstract: 181,921. Compton, J. H., and Midgley, A. H. May 7, 1921. Organ swell-shutter actions. -The speed of opening or closing of the shutters when the opening is considerable is made automatically to decrease towards the end of the movement. In Fig. 1, the apparatus is shown in the closed position. When the brush v on the pedal a makes contact at c or c', since the corresponding commutator segments g, g<1> respectively are opposite the space between the two groups of brushes r - - r<4> and r<5> - - r<9> on the sliding bar q, no electric circuit is formed and no movement of the shutters takes place. If the pedal is depressed on to the contact c<2> current flows from the source x, through brush v, contacts c<2>, conductor f<2>, commutator segment g<2>, brush r<5>, conductor s<3>, an electro-pneumatic device m<4>, which controls the smallest inlet valve i<4> of the pneumatic motor h, and through a conductor (not shown) common to all the electropneumatic devices, back to the source x. Hence the pneumatic motor is actuated, and the sliding bar q consequently forced downwards until the sliding contact brush r<5> is disengaged from commutator segment g<2>, whereupon the circuit is broken, movement ceases, and the swell shutters remain partly open. If the pedal is depressed so rapidly that it makes contact at c<@> before the penumatic motor moves, the largest inlet valve i<6> opens and the motor inflates rapidly. As the sliding bar is forced downwards, contact between the commutator segment g<6> and the brushes r<9>, r<8>, r<7> is successively broken and hence the inlet valve i<6> is closed and the intermediate valve i<5> opened through the contact between g<6> and r<6>. Finally, the smallest inlet valve is opened and closed in a similar manner and the sliding bar comes to rest with the interval between brushes r<5>, r<4> opposite the two segments g<5>, g<6>. The closing of the shutters is effected in a similar manner by contacts between the segments g - - g<4> and brushes r - - r' which control the outlet valves i<1>, i<2>, i<3>. To compensate for leakage owing to the compressing action of spring e, a cone or other valve n is provided to permit a constant now of air from the wind chamber k. Two motors may be used, one to open and one to close the shutters, in which case the spring e is unnecessary. The preferred form of electropneumatic device for operating the valves is illustrated in Fig. 3. When the valve t' is lifted by the energizing of the electromagnet t. the pneumatic p collapses under the pressure in the chamber u, and in collapsing lifts the valve o and puts the interior of the pneumatic z into communication with the atmosphere, whereupon the pneumatic collapses and lifts the valve i<1> from its seat.

Title: Closure for moulded plastics bottle
Inventor: HINDLE BRIAN ROBERT
IPC: B65D47/26
Filed: 1968-03-18
Abstract: 1,249,154. Bottle closures. BLEWIS & SHAW (PLASTICS) Ltd. 13 Feb., 1969 [18 March, 1968], No. 13097/68. Headng B8T. A closure for a moulded plastics bottle comprises a cap 9, Fig. 4, which engages the exterior of the bottle neck and is rotatable relative thereto, but axially fixed, and a bung 1, Fig. 1, having a skirt for compression within the neck where it remains stationary, both the cap 9 and the bung 1 having a set of perforations 11 and 3 respectively, so that relative rotation therebetween may bring them into register. Ribs 7 on the bung skirt are compressed in the neck so avoiding contraction of the set of perforations due to radial pressure from the neck. The cap 9 and the bung 1 may be assembled together by passing a central peg 14 of the cap 9 through a passage 15 of the bung 1, and hence may be fitted on the bottle neck as an integer. Relative rotation between the cap 9 and the bung 1 is limited by engaging a boss 18 of the cap 9 in a recess (17), Fig. 2 (not shown), of the bung. On rotating the cap, the boss 18 describes an arc within limits defined by the edges of the recess (17) so that at one edge the perforations are aligned and at the other edge they are not aligned.

Title: Improvements relating to gear grinding machines
IPC: B23F5/02
Filed: 1959-04-17
Abstract: 877,773. Gear-grinding. GLEASON WORKS. April 17, 1959 [April 18, 1958], No. 13228/59. Class 83 (3). [Also in Group XXIII] A machine for grinding straight or skew bevels &c, comprises two spindles 27, 39 on a head 13 mounted on a rotatable cradle 11, the spindles being inclined to the face of the cradle. The machine, with twin grinding heads, is generally similar to that described in Specification 778,479. Each head is carried on a slide 22 adjustable in a direction 24 on a plate 23 which is adjustable in a direction 26 on an angularly adjustable plate 25. The spindle 27 is driven by a motor 31 on the head and the wheel may be trimmed by a dresser 32. As the wheel is dressed, the edge 35 between the operative faces 16, 33 recedes along a line 36 parallel to the cradle axis. The larger wheels 14 interfere with one another if adjusted to grind small-diameter gears. Smaller wheels 41 are therefore fitted on the auxiliary spindle 39. The same dresser is used but with a modified tool carrying arm 43. When the larger wheels are used, a casing 45 containing the spindle 39 and a cover 53, enclosing a toothed driving belt 48, are removed. A protective cap 52 is fitted on each spindle 27 when the smaller wheels are used.

Title: Anti-dust ring
IPC: F16L27/08
Filed: 1963-04-04
Abstract: 991,991. Lip seals; rotary joints. FMC CORPORATION. April 4, 1963 [April 16, 1962], No. 13300/63. Headings F2B and F2G. A combined dust-sealing and internal pressure-relieving ring D for a fluid-conducting swivel joint, e.g. between two pipes 12, 14, Fig. 1, comprises an annular body 40, Fig. 4, having an outwardly extending lip 60 and being so shaped as to permit distortion of the ring, Fig. 8, in response to a predetermined fluid pressure difference acting across the ring when the latter is inserted in the swivel joint and allow fluid to flow across the inner peripheral surface of the ring from one side of the ring to the other. The ring may be of natural or synthetic rubber or of a rubbery copolymer of butadiene and acrylonitrile and is inserted in a recess 34 in the spigot end N of the pipe 12. The inner peripheral surface of the ring is formed with a conical recess 46 communicating with generally radial notches 68 in the face 44, Fig. 2. Under normal operating conditions the ring D is under slight axial compression in the recess 34 and prevents dust from entering the ball bearing area 16 of the joint. The lip 60 bears against the inner surface 76 of the socket end S of the pipe 14, the radial faces 42, 44 against the corresponding walls 70, 72 of the recess 34 and the inner peripheral surface portions 52, 56 against the bottom 74 of the recess. Should a main fluid seal F at the inner end of the joint fail, pressure fluid flows past the bearing 16 and works its way between the sealing face 42 of the ring D and the recess wall 70 thereby causing axial compression of the ring and consequent radial extension of its inner peripheral surface portion 52. The pressure fluid thus escapes, as indicated by the arrows in Fig. 8, through the recess 46 and the notches 68 out to atmosphere thereby relieving pressure on to the bearing and preventing damage thereof. In a modification, a double row ball bearing unit has its inner and outer races secured between inner shoulders and outer screwed end members at the spigot and socket ends of the pipes.
