Title: Improvements in or relating to Apparatus and Process for the Cooling and Coiling of Hot-Rolled Light-Gauge Strip
IPC: B21B45/02
Filed: 1968-08-28
Abstract: 1,191,355. Rolling. JONES & LAUGHLIN STEEL CORP. 28 Aug., 1968 [29 Aug., 1967], No. 41167/68. Heading B3M. Hot-rolled light gauge strip is cooled between a roll stand 1 and a coiler 13 by means of upper and lower high-pressure sprays 6 and 8, the coiler 13 immediately following the sprays. The coiler is closer to the stand than is usual to minimize the risk of cobbles and flutter in the strip, and the upper sprays are positioned relatively close to the strip surface. Longitudinal bars project downwardly from the sprays to protect them from cobbles. When heavier gauge strip is cooled the sprays 6 are pivoted upwardly about one edge, and a deflector 15 allows the strip to pass over a further cooling table to a coiler 24.

Filed: 1961-11-17
Abstract: 1,018,584. Conveyers; stacking; load handling. DAVY & UNITED ENGINEERING CO. Ltd. Oct. 29, 1962 [Nov. 17, 1961], No. 41223/61. Headings B8A, B8C and B8H.  Coils 12 of wire are detached from respective hoops 11 of a chain conveyer by a member 19 which pivots about an axis 72 to lift each coil to a horizontal position 13 on a platform 17. The member 19 has spaced horizontal and spaced vertical respective surfaces for supporting the upper part of the bore, and the leading end face of the coil. The member 19 passes to a retracted position below the table 17. Arms 84 pivoted at 85 to the member 19 engage cam surfaces 89 as the member 19 is retracted. The arms 84 are thereby caused to engage the bore of the coil and push it forward to prevent it being nipped between the member 19 and the table 17. Each coil is swept from position 13 by an arm 23 to a platform 26 of a strapping machine 27, and thence to a roller conveyer 30. The latter comprises two sections 32, 33, each tiltable to a position 33a (Fig. 2) from which the ring 12 may slide on to the lower limb of a C-hook 50. When ten coils have been collected on the hook 50 the latter is upended by a crane (not shown) and the coils are removed to storage. If it is desired to collect the coils on a similar C hook 51, a stop (62, Fig. 4, not shown) is raised to retain each coil from proceeding further than the roller conveyer section 32. In a modification (Fig. 12, not shown) there are two members 19 and associated tables 17 (to provide for continuous operation during servicing), and an endless conveyer is disposed between the tables 17 and the banding machine.

Title: Improvements in or relating to microwave pulse amplifiers
IPC: H03F7/02
Filed: 1960-12-01
Abstract: 961,445. Parametric amplifiers. WESTERN ELECTRIC CO. Inc. Dec. 1, 1960 [Dec. 17, 1969], No. 41341/60. Heading H3B. To amplify a microwave pulse, the permeability or the permittivity of a transmitting medium in a waveguide is reduced over a period of time including the whole transit time of the pulse. The permeability or the permittivity is then increased in preparation for amplification of another pulse. Microwave pulses 31, 32, Fig. 3, are transmitted from source 20 over a guide 10 which is capacitively loaded by conductive rods or fingers 12 to slow the wave. Saw-tooth waves 33 of biasing current are applied to a strip line 13. The biasing current drives a ferrite insert 11 in the guide down a falling portion of the magnetic field/permeability characteristic Fig 2. Thus as the bias rises, the permeability falls. The wave velocity of the miro - wave pulse in the medium increases with the bias but as the spacial distribution of the pulse is unaffected, the frequency increases. There is also an increase in amplitude. In a modification, Fig. 4, the microwave pulse from a source 44 is transmitted through a band-pass filter 42 to the medium 41. The pulse is reflected backwards and forwards through the medium by filter 42 and high-pass filter 43 with consequent amplification and frequency shift until the frequency is high enough for filter 43 to accept it for the load 45. A sinusoidal wave may be used instead of the saw-tooth wave for bias. The slow-wave guide structure may be of the kind described in Specification 724,083 or in U.S.A. Specification 2,659,817.

Title: Improvements in and relating to Frequency Modulation Receivers.
Inventor: HACKER ARTHUR GEORGE
IPC: H03G3/34
Filed: 1966-09-21
Abstract: 1,172,814. FM receivers. HACKER RADIO Ltd. 19 Oct., 1967 [21 Sept., 1966], No. 42137/66. Heading H3Q. A frequency-modulation receiver is muted in the absence of an input signal by blocking the limiter stage. In the arrangement shown the transistor 27 conducts when there is no input signal and thereby biases the base of the limiter transistor 14 to cut-off. When an input signal is received, an I.F. signal is fed through amplifier 22 to rectifier 29 which develops a bias sufficient to cut off transistor 27 thereby allowing the limiter transistor 14 to function normally. The adjustable resistance 28 allows the muting threshold level to be altered, and a switch 36 allows the muting circuit to be switched out. The selectivity of the muting circuit depends on the selectivity of tuned circuit 25, and in a receiver incorporating automatic frequency control may be such that the receiver is correctly in tune before the muting circuit is disabled.

Filed: 1967-09-19
Abstract: 1,129,349. Rock drills. INGERSOLL-RAND CO. 19 Sept., 1967 [19 Sept., 1966], No. 42542/67. Heading B3C. [Also in Division B4] A rotary-percussive rock drill comprises an impact piston 22 actuated by compressed fluid under the control of a valve 32, a fluid-operated motor 64 for rotating a drill steel 20 relatively to the piston and adapted to be fed continuously with compressed fluid via a valve 92 or, intermittently, via a conduit 98 communicating with the valve 32. The impact piston is reciprocated by means of compressed air fed through a pipe 30 into a chamber 34 and thence to one or other side of the piston head 24 via the valve 32 and passages 48a, 48b, 58 the valve being reciprocated by air fed through passages 54, 56. When it is desired for the tool steel to be rotated continuously, air is fed via a pipe 100 and valve 92 into the rotary-motor 64; the direction of rotation may be reversed by feeding the air through a pipe 96 instead of pipe 100. When an intermittent rotation of the tool steel is required, air is fed via a pipe 102 so as to act on the valve 92 thereby moving it against the action of a spring 94 as shown in Fig. 3. The rotary motor is then in communication with chamber 34 via the pipe 98 and the valve 32 so that on each working stroke of the piston the tool steel is rotated, the latter being stationary on the up stroke of the piston. If it is desired to reverse the position, a screw connection 130 from the pipe 98 is removed from a bore 132 and replaced in a bore 128, a plug 136 normally closing the latter bore being then screwed into the bore 132.

Title: Launchers for missiles
Inventor: BALL JOHN RAYMOND
IPC: F41F3/045
Filed: 1966-09-23
Abstract: 1,206,945. Recoilers guns. BRITISH AIRCRAFT CORP. (OPERATING) Ltd. 30 Nov., 1967 [23 Sept., 1966], No. 42708/66. Heading F3C. A missile is housed in a tube which serves as external protection for the missile up to the moment of launch and which, for launching of the missile, is temporarily coupled to a mounting member by which the tube can be held and aimed. Under combat conditions the tube is expendable. In a particular example, the tube 2 is joined at its rear end to an assembly 4 which houses an expulsion charge (not shown) and which terminates in a recoil reaction nozzle. The tube is coupled by means of a reinforcing collar 10 at its forward end to a stock 12 which includes a cradle 14 to embrace the collar through about 170 degrees and a clamping member 16 which forms an extension of the cradle through about 45 degrees and which is hinged to the cradle. The member 16 is controlled and locked by a lever 20 which actuates a cam 22 which engages ribs 23 on the exterior of the member 16. A lug (not shown) extends radially from the collar 10 and is received in a recess (not shown) in the surface of the cradle 14, this lug locating the tube 2 angularly and axially. The lug and recess accommodate an electrical socket and plug, respectively. An arm 32 carrying a shoulder butt 34 extends rearwards from the cradle 14, and two hand grips 36, 38 extend from the front of the cradle. The right-hand grip 36 houses a lever (not shown) by which the flight guidance is controlled. A monocular sight 42 is attached to a platform on top of the cradle 14. The left-hand grip 38 incorporates a trigger 44 and a safety switch 46. The guidance control lever operates potentiometers which are connected to a guidance control transmitter by a flexible cable 47. The expulsion change is fired electrically when the trigger 44 is pulled. The source of electric power is a battery pack carried by the operator and an electric circuit passes from the trigger 44 through the plug and socket from the cradle 14 to the lug on the tube 2, and then along wires housed in a thickened part of the wall of the tube to the rear assembly 4. A piston in front of the expulsion charge is driven forward on firing and the missile moves forward, knocking off a front cover on the tube. A rear cover on the tube is burst and gas discharged through the recoil reaction nozzle. A rocket propulsion charge inside the missile is fired as the missile is launched. In an alternative form, a guidance control with its own sight is handled by a second man alongside the launcher. Furthermore, the invention can be applied to missiles launched from vehicles or fixed mountings. It can also be applied to unguided missiles.
