Title: Improvements relating to rolling appliances for rolling roads, footpaths, air strips, fields and like ground surfaces
Inventor: TOPE EDWARD RICHARD
IPC: E01C19/25
Filed: 1953-05-06
Abstract: 732,485. Land rollers. TWOSE (MANUFACTURING), Ltd., E. V., [formerly TWOSE, Ltd., E. V.]. July 28, 1953 [May 6, 1953], No. 12656/53. Class 6 (1). A rolling appliance for roads, footpaths, fields and like ground surfaces comprises a steerable front roller 2 and two driven rear rollers 4 mounted on a chassis 1, the appliance being driven by a tractor or other self-propelled wheeled vehicle mounted on the chassis 1. As shown the tractor is driven up removable ramps 14 on to humped runways 6, the front wheels 8 being located in recesses 10. Pivoted levers 25 engage under the tractor rear axle and are connected to the hydraulic lifting gear L. Upward movement of the lifting gear raises the rear wheels clear of the runways and the levers 25 are clamped in the raised position by struts 23. Sprockets 26 are mounted on the rear wheels 12 and drive the rear rollers 4 through chain and sprocket gearing. A steering column 37 is inserted through the tractor steering wheel and controls the front roller by means of sprockets and a chain 40. The tractor rear wheels may drive the rear rollers by direct contact or alternatively the rear wheels may contact rollers disposed with their upper surfaces substantially in line with the runways, the rollers being connected to the rear rollers 4 by chain and sprocket gearing. In those cases the levers 25 are omitted as there is no need to raise the tractor rear wheels. A modified arrangement for steering the front roller is shown in Fig. 5 where the roller 2 is mounted in a frame 44 pivoted to a yoke 45 which is provided with a pivot pin 46 journalled in the chassis. A chain 49 is connected to the frame 44 and engages sprockets 51, 52. A sprocket 54 is coaxial with and connected to the sprocket 52 and the steering column 48 is provided with a sprocket 56 connected by a chain 55 to the sprocket 54. The rollers may be of hollow construction filled with sand or water.

IPC: A47B31/00
Filed: 1956-04-25
Abstract: 789,931. Semi-conductor materials. MULLARD RADIO VALVE CO., Ltd. April 25, 1956, No. 12697/56. Class 37. An electrode is formed on a semi-conductor by heating the semi-conductor and a wire held thereon in a jig to a temperature above the eutectic point of the alloy of the semi-conductor and the wire but below their individual melting-points so that, on cooling, an alloy containing the semi-conductor in excess of the eutectic proportion solidifies first. As shown, Fig. 1, through a vertical aperture 3 in a carbon jig 1 placed on the surface of a slice of N-type monocrystalline germanium 2, is disposed a gold wire 4 whose lower end touches the germanium 2. When the arrangement is heated to between 356‹ and 936‹ C. the gold 4 alloys with the surface germanium, moving downwards until stopped by the engagement of a bent-over portion 5 on the jig 1, when the alloy electrode 6 (Fig. 2) detaches itself from the wire 4 and the heating is stopped. On cooling, gold-saturated germanium recrystallizes on the undissolved N-type germanium forming a P-N junction, further solidification presumably being of the gold-germanium eutectic. A connecting wire is soldered to the electrode 6 and a connection is provided to crystal 2, which is etched, e.g. in hydrogen peroxide.

Title: Methods of operating and control arrangements for electric arc furnaces
IPC: H05B7/148
Filed: 1970-03-17
Abstract: 1309095 Arc furnace melting DAIDO SEIKO KK 17 March 1970 [17 March 1969] 12888/70 Heading C7D [Also in Division G3] The supply of energy to an electric arc furnace is controlled by integrating the rate at which energy is supplied and changing the rate for a succeeding programmed melting section in response to a comparison between the integrated rate and a programmed value for the section. As shown, predetermined values of the energy consumption for each section of a steel melting operation are pre-set on a device 1 and compared in a device 3 with the number of pulses from an input power integrator 2. At equality a signal to a voltage tap-charger 4 changes the furnace input power level to the value pre-set for the following melting section. As the arc-length is related to power-factor the optimum power-factor is pre-set in a device 5 and compared with the actual power-factor from a detector 6 to control a current adjustor 7. The instant at which a melting operation has ended is determined by a calculator 9, responsive to the set-in scrap weight and a signal from a KWHR pre-setter 8, the product being compared in the device 3 with the input power from the integrator 2. During a melting operation, the value set in the pre-setter 8 is adjusted by a reviser 10 in dependence upon modifying curves determined from normal operating practice.

Title: Improvements in or relating to automatically controlled recording apparatus
Inventor: KEEN HAROLD HALL
IPC: G01G23/42
Filed: 1953-05-08
Abstract: 744,321. Photo-electric weighing apparatus. BRITISH TABULATING MACHINE CO., Ltd. May 8, 1953, No. 12898/53. Class 40 (3). [Also in Groups XVIII, XIX and XXXVIII] In a recording apparatus (see Group XIX), a disc 54 is driven to follow a disc 50 rotated by a weighing machine through an angle proportionate to weight. A photo-cell 53 carried by the disc 54 initially receives light from a lamp 52 supported by an arm 51 secured to the disc 54, the light passing through a hole 59 in the disc 50. As the latter moves, the light is cut off and then temporarily passed by a hole 60 in the disc 50. A relay R42 connected to the photo-cell 53 is thus de-energized and then momentarily energized, and its contacts R42a first operate a relay circuit R43 and then restore the circuit R43 and operate a connected circuit R44. The circuits R43 and R44 are similar to those described in Specification 704, 860, [Group XIX], and comprise relays as described in Specification 675,844, [Group XXXVII], arranged to operate at the end of an applied pulse. The relays R43, R44 control electromagnets R40, R41 which operate clutches driven by an electric motor 72 and driving the disc 54 through differential gearing which adds the drive movements. The magnet R41 is first energized and then also the magnet R40 to cause the disc 54 rapidly to follow the disc 50. When the latter stops, the photo-cell 53 is momentarily energized through the hole 60 and its relay R42, through the relays R43, R44, which are respectively operated and restored, de-energizes the magnet R40 to decrease the speed of the drive to the disc 54. A further pulse is then produced by the photocell 53 as light passes through the hole 59. This pulse restores the relay R43 and, as a consequence, the magnet R41 is de-energized so that the disc 54 stops. Operation of the relay R44 at this time is prevented by contacts R46b of a relay R46 energized by the first operation of the relay R44. During the rotation of the disc 54, holes 58 allow light pulses to pass from a lamp 56 to a photo-cell 57 which through a relay R13 produces pulses that are counted by a relay counting circuit. Removal of the weight opens a micro switch 40 to energize a relay R45, contacts of which reverse the circuit of the motor 72. The switch 40 also allows operation of the clutch magnet R41 when the photo-cell 53 receives a light pulse due to the passage of a second hole 60 as the disc 50 returns to its zero position. The disc 54 is thus driven in a reverse direction to its zero position, in which a circuit is completed through a conducting segment 90 fast with the disc 54 and brushes 89, 91 to restore the relay R44 and so to de-energize the clutch magnet R41. The relay R43 is restored as a result of the light pulse due to the passage of the hole 60 as the zero position is approached.

Aeroplanes; planes, arrangement and construction of; balancing.-The angle of incidence of the. lower plane 2 and of auxiliary planes 7 can be varied to control flying speed and to facilitate ascent, descent and banking by mechanism contained within the main plane 1 and the connecting struts. The planes 7 are at the forward ends of auxiliary vertical and horizontal stabilizing planes 5, 4. The transmission mechanism for warping the planes 2, 7 passes inside the plane 1 and through tubular struts to the plane 2 or through the planes 5 to the planes 7. Thus the lower plane 2, the axis of which is supported by bridge pieces 33, Fig. 9. on struts 25, is warped by push-and-pull rods 23, Fig. 7, which extend from the fuselage along the rear spar 3<11> of the plane 1 and are connected by rocking links which carry bevel gears for rotating shafts which pass through the struts 25 and operate bevel gears on the main forward spar of the plane. The mechanism is actuated by hand, or by the main engine or an auxiliary motor through a clutch and reduction and reversing gears. Similar mechanism is employed to control the planes 7, operating in this case to raise or lower a V-frame 14, Fig. 2, connected to the trailing edge of the plane, which tilts about its forward spar, which is supported from the plane 1 by struts 12, 13. The plane 2 can be tilted to an angle + 16‹, and the planes 7, in like or opposite, senses, to angles + 16‹. The two sides of the biplane are constructed to be separately detachable from the fuselage. Specification 236,176 is referred to. According to the Specification a.s open to inspection under Sect. 91 (3) (a), cable or screw transmission may be employed to tilt the planes 2, 7. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to hydraulic control apparatus
IPC: F15B11/12
Filed: 1950-05-26
Abstract: 716,177. Hydraulic control apparatus. BENDIX AVIATION CORPORATION. May 26, 1950 [May 31, 1949], No. 13342/50. Addition to 715,111. Class 69 (2) The invention comprises an improvement in or modification of the hydraulic apparatus as claimed in claim 1 or 2 of the parent Specification, having an actuating mechanism for the valve, which actuating mechanism comprises a member reciprocated by the motor piston and having stop means thereon adapted to contact an abutment member on the valve rod for returning the valve to its neutral position, wherein the stop means is formed by a V-shaped spring clip the two legs of which are formed with juxtaposed windows for receiving the member reciprocated by the motor piston one of the windows having a length slightly greater than the thickness of the member and the other having a length substantially greater than the thickness of the member, the effort transmitted by the abutment member on the stop means being exerted on the leg having the smaller window. Fig. 1 shows an hydraulic unit of the type disclosed in the parent Specification and comprising a motor cylinder 10 and a piston (not shown) connected to a piston rod 11, controlled by a valve 13, including a valve member (also not shown) which is connected to a valve operating rod 14. The valve member is displaceable in opposite directions from a neutral position by a handle 15 and is returned to this position by the corresponding movement of the motor piston by means of abutments 17, 18 carried by a bar 16 connected to the piston rod 11. Each abutment comprises a clip of sheet spring metal such as steel of V-shape. Each arm of the clip has an opening through which the rod passes and the opening in the arm 21 is slightly greater in length than the thickness of the bar and the opening in the arm 20 is substantially greater in length than the thickness of the bar. The distances .of the outer edges 23a, 24a of the openings from the adjacent edges of the legs 20, 21 are approximately equal and the opening 23 is extended closed to the apex 22. The normal angle of the V when the clip is unrestrained is substantially greater than its angle when in use so that the legs 20, 21 have to be squeezed together to permit placing of the clip on the bar. When released both edges 24a, 24b of the opening 24 contact the corresponding faces of the bar. The clips co-operate with a shoulder 19 carried by the valve piston rod and this tends to force the edges of the openings 24 against the bar and prevents slipping of the clips. Preferably the clips are of harder material than the bar so that the edges of the openings 24 tend to cut into the bar.
