Title: Improvements in or relating to heat storage unit
IPC: C09K5/06
Filed: 1952-02-12
Abstract: 708,471. Heat-storing apparatus. TELKES, M. Feb. 12,1952 [April 25, 1951], No. 3674/52. Class 64(2) [Also in Group XXIII] With glass 14<SP>1</SP> having an uneven surface to promote crystallization when heat is given up, disodium orthophosphate and water, e.g. as the dodecahydrate or a concentrated solution, are contained in a closed vessel 10 to form a storage unit for heat, such as solar heat. The sodium phosphate, considered as anhydrous, comprises 35-39.6 per cent by weight of the phosphate plus water. The containers 10 are of metal, or glass with a roughened interior surface and the glass inside may be glass wool, in the form of a matrix 14<SP>1</SP> filling the container as shown, a bundle of glass wool secured to a roughened, hollow, glass float, Fig. 3 (not shown), or a number of floating, cellular glass bodies (see Group XXIII) with uneven or fractured surfaces. This glass is thus maintained at the upper part of the heat storage material which' material may contain up to 0.5 per cent sodium chromate or dichromate as a corrosion-inhibitor. All the glass used contains calcium. A number of sealed containers 10 are stacked in tiers in a bin 16 with adjacent tops and bottoms in heatconducting contact. Spaces s are left for the circulation of a fluid such as air between the containers in each tier and a baffle 17 prevents short-circuiting between an inlet 18 and an outlet 19.

Filed: 1927-02-09
Abstract: 265,975. Beauchamp, (nÚe Faure), D. F. Feb. 9, 1926, [Convention date]. Look-out reflectors. - The frame of a rectangular rear view observation mirror for a vehicle or similar reflector is built up of two end members 11, Fig. 6, two longitudinal members 12 having tongues 14 for holding the end members 11 in position, and two end caps 15 which hold the members 12 in place, the entire mirror being adjustably supported on arms 30, Figs. 3 and 4, engaging and retaining in place the caps 15. The mirror preferably comprises two panels 10 arranged back to back, one having a highly polished and the other a subdued reflecting surface, while one or more strips 16 disposed hetween the panels and having end tongues 17 overlapping the edges of the panels may be provided for strengthening the mirror. For adjustment purposes the mirror is pivoted on the free ends of the arms 20 which, at the opposite end, are pivoted to the vehicle body. The pivot pins for the mirror are formed by bolts 21 passing through bosses 22, 18 in the members 11, 15 respectively, and engaged by nuts 23, which bear against spring washers 24 and so press the arms 20 against the caps 15. Studs are provided on the caps 15 to co-operate with a series of apertures 29 in the arms 20 to hold the mirror in any adjusted position. The pivots for the arms 20 are formed by bolts 30, and the arms are provided with series of notches 33 co-operating with lugs or pins 34 on stamped-up ears 31 on the support 32 so as to retain the arms in any adjusted position. In the case of a long or heavy mirror an additional support is provided in the form of spring 35 engaging the lower edge of the mirror and having an arc-shaped portion 36 curved about the pivotal axis of the mirror as centre. The spring 35 may have two seats 39, 42 for the mirror, and the portion 36 is clamped in a bracket 37 mounted at the free end of a short arm 20<1> pivoted in a similar manner to the arms 20.

Abstract: 1531864 Crane safety devices KRUGER & CO KG 30 Jan 1976 [4 Feb 1975] 03701/76 Heading B8H [Also in Division G3] Apparatus for controlling the drive for a crane jib (not shown) slows down the movement of the jib as the load moment increases, accelerates it as the load moment decreases and, as the maximum load moment is approached the jib movement is steadily brought towards zero. As shown, an electrically operated throttling valve 10 acts as the positioning agent of the jib by controlling a double-acting hydraulic cylinder (1), Fig. 1 (not shown). A setting device 12 consists of a potentiometer 15 with a sliding contact 16 set by a pivotable hand lever 17. In the neutral position shown, the contact 16 rests on an insulating piece 16 at the centre of the resistance which is connected at its free ends A, B to one pole of a voltage source. A linking element 14 consists of a potentiometer 21 with a sliding contact 22 set by a servomotor 23 operated by a signal from a monitoring device 13 which measures the instantaneous load moment of the crane jib. Movement of the lever 17 in the direction of the arrow 24 initiates raising of the crane jib, the operation of the throttling valve being modified by the action of the load moment monitoring device 13 on the contact 22.

Abstract: 963,635. Tyre building machines. DUNLOP RUBBER CO. Ltd. Jan.26, 1961 [Feb. 4, 1960], No. 3938/60. Heading B7C. In a tyre building machine, ply consolidation and turn-over is effected by a pair of spinners 2, 3 rotatably mounted on arms 11 pivoted one of each of a pair of supports 4, 5 and disposed on diametrically opposite sides of the cylindrical building drum 1 and on opposite sides of the mid-plane of the drum, the spinner arms 11 being movable about their pivots 12 by pneumatic cylinder and piston units 18 to press the spinners against the drum surface, and being swingable about the axis of a shaft 14 disposed at right angles to the axial direction of the drum to rotate the spinners about the rounded shoulders of the drum and vary the angle between the axes of each spinner and the drum, the supports 4, 5 being movable simultaneously in opposite directions axially of the drum along horizontal slides 37 on a pair of carriages 38 for traverse of the spinners axially of the drum, and the two carriages 38 being mounted on a common slide 7 perpendicular to the axial direction of the drum for simultaneous movement of the spinners towards or away from each other radially of the drum to effect ply turn-down or turn-up along the drum shoulders. As shown, each spinner arm pivot 12 is journalled in a support 13 carried by the shaft 14 which is in turn journalled in a carriage 16 movable along the slide 37 by a lead screw (not shown) driven by an electric motor 39 on the carriage 38. Rotation of the shaft 14 to effect the ply-turning spinner movements such as B-C, Fig. 4, and K-B and G-J of Fig. 6, is effected by a worm-wheel 22 on the shaft 14 driven by a worm 23 rotatable by a motor 24 on the carriage 16. The two carriages 38 are movable along their common slide 7 by a common lead screw 8, having oppositely screw-threaded portions 8a, 8b for the respective carriages, driven by a motor 9 on the machine frame 6. The various traversing movements of the spinner effected by the motors 9, 24 and 39 are controlled by groups of limit switches selectively rendered operative by a selector switch in accordance with the particular stitching and turn-down or turn-up operation desired.

Title: Improvements in or relating to electronic circuit arrangements for generating voltages of rectangular waveform and/or pulses of short duration
IPC: H03K5/07
Filed: 1945-02-16
Abstract: 588,416. Pulse modulation and generating circuits. JELONEK, Z., ANDERSON, E. W., MAcMILLAN, J. G., and McDERMOTT, T. J. Feb. 16, 1945, No. 4025. [Class 40 (v)] In a pulse generator, a cyclically varying wave is applied to a control electrode of a transitron-connected valve to cause it to operate at a predetermined part in the cycle. A modulating voltage may be applied to the transitron to phase-modulate the output pulses, and a number of transitrons may be employed to permit multiplex working. The valve V1, operating in the manner described in Specification 583,630, feeds a positive-going waveform to the screen grid of transitron-connected valve V2, having a condenser C2 between the anode and control grid causing the valve V2 to pass into the state where anode current flows. The anode potential falls suddenly, driving the grid nearly to cut-off, due to condenser C2, and then falls linearly to generate the slow sweep of a saw-tooth wave. The output from the anode is fed through cathode follower V3 to trigger the transitron-connected valve V4, the point at which the valve passes to the state where anode current is cut-off being determined by the cathode potential, adjustable by varying resistance R2. The cessation of anode current causes the damped circuit L1, R3 to ring, producing a short positive pulse, the corresponding negative pulse when anode current commences being suppressed in subsequent apparatus. By applying a modulating voltage over transformer T1, the valve V4 reverses earlier or later to produce phase-modulated positive output pulses, and by employing a number of valves V4 with different cathode potentials, a series of pulses may be produced for multiplex working.
