Filed: 1951-05-31
Abstract: 693,662. Shoots and hoppers; trimming and spreading apparatus. FEIGENSPAN, O. May 31, 1951. [Oct. 1, 1948] No. 13997/51. Classes 78 (i) and 78 (iv). In furnaces of great grate-width fuel is fed evenly from a storage bunker 222 to the grate hopper 219 by a reciprocating distributing frame 201 placed between them which is closed by a floor 215 except for two outlets near the front and rear. Delivery hoppers may be attached to the outlets. In a modification the floor can be disposed approximately at the top of the frame and provided with depending vertical members. Instead of being flat the floor may slope downwards from the centre towards each outlet which may be subdivided by an inverted V-shaped partition. The frame may be provided with a stirring device comprising a motor-driven shaft 212 provided with vanes 213. The centre of this shaft is connected by worm gears 216, 217 to a sprocket 218 which engages a fixed chain 220. The bunker outlet 221 is adjustable vertically and carries sprinkler nozzles 223. It may be subdivided by a partition 232 when different fuels are fed simultaneously. Outlets 231 are formed in the ends of the frame to permit the discharge of excess material. Reversing switches for the driving motor are disposed at the end positions of the frame to be actuated by it. If the consumption of fuel in the furnace stops, the fuel rises in the grate hopper and eventually the top layer is pushed to the side by the frame thereby moving a swinging arm placed in front of the reversing switch to actuate it. The frame reverses its travel, but the switch remains open since the return of the arm is prevented by the fuel. At the end of its travel the frame opens the other switch and remains at rest until the sinking of the fuel releases the swinging arm.

Title: Mechanism for advancing a series of articles step by step
Inventor: BROWN GEORGE MARTIN
IPC: G03D3/10
Filed: 1961-04-12
Abstract: 934,070. Photographic processing apparatus. ILFORD Ltd. March 29, 1962 [April 12, 1961], No. 13199/61. Class 98 (1). [Also in Group XXX] Sheets 10 of photographic film are advanced successively through tanks I-VII by the action of a transfer member 14 having vertical and horizontal components of motion due to its suspension from. continuously moving endless members 15. The sheets 10 are carried on rods 11 which rest on rails 19. Prior to processing the rods 11 carrying their associated sheets are placed in turn on an inclined delivery section 13 of the rails 19. When the transfer member (which comprises a pair of beams 14) is on its upward path of travel (Fig. 3), a pair of hooks 23 (one, only visible in Fig. 3) on respective plates 22 at the extreme left-hand ends of the beams 14, rise into engagement with leading rod 11 on the section 13. The remaining rods are held clear during this operation by the action of a plate 28. Further plates 22 engage respective rods 11 carrying sheets 10 in the tanks (e.g. tank I, Fig. 3) and cam each one from a pair of notches 21 in which it is resting, into the next forward pair of notches. The most forward pair of plates 22 corresponding to each tank are, however, formed with hooks 23, and these pick up the most forward rod 11, and its associated sheet is thereby lifted up until its lower end clears the top of the tank. As the beams 14 pass around the pulleys 18 carrying the endless chains 15, the rod 11 is traversed horizontally and is then lowered into the next successive tank. In a tank in which there is provision for only one sheet the corresponding hook 23 does not need an associated plate 22 (Tank II, Fig. 3). Where more than three sheets are accommodated in a tank, the fourth and fifth plates 22 need to be pivotally mounted at 24 so that they may be able to turn out of engagement with remaining rods 11 on the downward travel of the beams 14. The rods 11 are eventually and successively transferred to a delivery section 25 of the rails 19.

Abstract: 1389203 Transistor crystal oscillators BRITISH OXYGEN CO Ltd [trading as EDWARDS HIGH VACUUM INTERNATIONAL] 5 June 1972 [5 May 1971] 13372/71 Heading H3T [Also in Division G3] In an oscillator circuit including a piezoelectric crystal X connected for series resonance between the emitter of a first transistor T1 and earth, the connection between the crystal and earth is direct without interposition of any component and a second transistor T2 has its base coupled to the collector of the first transistor, its emitter arranged to be maintained in operation at a fixed potential and its collector connected to its base through a resistor R3 to provide negative feedback and coupled to the base of the first transistor T1. The oscillator output voltage Vo is maintained constant by the operation of transistors T3 and T4 which operate to limit the voltage across the crystal X. To avoid distortion due to overloading of the transistor T1 when the resistance of the crystal X is small, the value of R3 is increased and an additional resistor R12 is inserted to reduce the alternating voltage at the base of T1. A capacitor C5 provides a phase shift to compensate for the effect of cable capacitance in parallel with the crystal X. A simplified version of the oscillator including only R1-R4, C, X and T1, T2 is described (Fig. 1, not shown) and circuits in which T1 and T2 are both of PNP type or T1 is NPN type and T2 is PNP type are described (Figs. 2 and 3, not shown).
Patent GB-134614-A (GB)
IPC: F03D9/32
Abstract: 134,614. Mortley, G. E. Nov. 5, 1918.. Dynamos, driving. -Air-screwdriven dynamos for aircraft are provided with centrifugal governors to prevent excessive speed. In the arrangement shown in Fig. 3, a friction clutch is mounted between the air-screw 6 and the dynamo 2 and comprises a shallow box 7 secured to the dynamo shaft and provided with a loose cover-plate 8, and an internal plate 16 connected by a one-way claw-clutch 20 to a sleeve fixed in the boss of the airscrew. The plate 16 is provided with friction surfaces, such as cork insets 18, which are normally gripped between the box 7 and its cover-plate 8 under the action of spring studs 10. When the speed becomes excessive, weights 12 pivoted to the box 7 fly out and press on studs 15, thereby relieving the pressure on the clutch plate 16. The single plate 16 may be replaced by a number of plates alternately free and secured to the box 7. A thrust bearing 22 prevents axial pressure of the airscrew from being transmitted to the clutch. When the machine is driven from batteries as a motor, air reaction against the propeller causes it, after a few turns, to slide outwards along the shaft and disengage itself by means of the clutch 20. In the arrangement shown in Fig. 8, the airscrew is arranged between the clutch 7 and the dynamo.

Abstract: 646,357. Aerials;radio navigation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Mav 29, 1945, No. 13491. Convention date, May 26, 1943. [Class 40 (vii)] A short wave directive antenna is formed by attaching a conductive rectangular flap 12 along one edge to a conductive base sheet 10 so that there is a small angle between them. The base sheet may be large, e.g. the side of an aircraft fuselage. The triangular ends of the antenna are preferably closed and a curve (Fig. 15, not shown) relating width to length for an antenna with ends closed is given. To prevent ingress of dirt and moisture, the open bottom edge may be filled with dielectric material. Connection to the antenna can be made by means of a coaxial feeder 15, the outer sheath being connected to the sheet 10 and the inner conductor to a point mid-way along the flap. The vertical distance of the connection from the edge of the flap may be chosen to give a particular terminal impedance. Maximum radiation occurs downwards along a line making an angle of 45 degrees with the sheet 10 and at right angles to the line of attachment of the flap; to increase the directivity a second reflector flap 22 may be mounted above the radiator with its open edge just overlapping the latter's attached edge. The units may be tuned either by U-shaped adjustable attachments 13 and 23, or by using a capacity plate mounted on a threaded rod screwed through a boss on the lower edge of the reflector, Fig. 11 (not shown). The antennae may be mounted in arrays, an array of four antennµ with reflectors and fed in phase by branched feeders tuned by stubs is described with reference to Figs. 8 and 12 (not shown). Radio navigation.-In order to estimate drift an aircraft 1, Fig. 2, fitted with the antennµ described, radiates two lobes of energy Pb and Sb of the same frequency downwards at an angle of 45 degrees. After diffuse reflection by the land or sea surface S, energy is received by the same aerials and the signals from the port and starboard sides are compared in frequency, the beat frequency being proportional to the craft's rate of drift.
