Title: Absorbing impact energy in automobile vehicles
IPC: B60R19/26
Filed: 1973-05-22
Abstract: 1430648 Vehicle bumpers SOC ANON FRANCAISE DU FERODO 22 May 1973 [23 May 1972 14 May 1973] 24466/73 Heading B7J [Also in Division F2] An energy absorbing assembly on a vehicle absorbs energy in an impact at a rate which is variable in response to seat belt tension in the vehicle. As shown in Fig. 2, an hydraulic shock absorber comprises a piston 15 carried by a rod 13 connected to the vehicle body, and a cylinder 11 supporting a bumper bar (12), Fig. 1 (not shown), the bumper bar being biased away from the vehicle body by a spring 15<SP>1</SP> abutting the piston 15. The two chambers 19 and 21 on each side of the piston 15 communicate via a bore 16 through the piston, this bore consisting of two portions 17 and 18 connected by an annular recess 25 in a valve 22 which is movable against a spring 27 in a radial bore 23 of the piston 15. In the normal rest position shown in Fig. 2, only a restricted flow through recess 25 is possible, but the valve 22 may be displaced by hydraulic fluid acting on its face 29 so as to align recess 25 with bore 16 and thus decrease the resistance to flow between the chambers 19 and 21. The radial bore 23 is connected through a duct 30 in the piston-rod 13, a pipe 32 and a calibrated valve 35 to a chamber 33 of an hydraulic device 34, Fig. 3. This device 34 contains a piston 37 whose rod 39 carries a part of a seat belt 41 at 42 so that if a vehicle occupant is thrown forward, the belt tension increases and pulls the piston 37 in direction f, thus increasing the pressure within the chamber 33. When a predetermined pressure is reached, valve 35 opens and the pressure is transmitted to move the valve 22 of the shock absorber in direction f 1 , thus decreasing the stiffness of the shock absorber. In another form, Fig. 4 (not shown), a bumper bar is supported by a member (50) which is slidable within a housing (51) to crush a deformable structure (67) so as to absorb impact energy. However, unless seat belt tension is sufficient to withdraw a piston (57) by deforming an elastomer sleeve (64), the piston (57) is normally engaged in a notch (52) of the member (50) so as to immobilize the said member.

Filed: 1964-06-12
Abstract: 1,071,691. Interferometric spectrometer; measuring pressure electrically. DESIGN Inc. June 12, 1964 [June 21, 1963], No.24531/64. Headings G1A and G1N. [Also in Divisions G2 and G3] An interferometric spectrometer comprises an interference filter 36, Fig. 2, in front of a series of Fabry-Perot etalons 38, 40, 42 each of the etalons having a pair of optical plates with a predetermined spacing between them, the ratio of the smallest to the largest spacing between any of the plates being between 0À5 and 1À0. As shown, each etalon is enclosed in an air-tight chamber 52, 54, 56, and a servo-mechanism is provided for varying the pressures in the chambers during scanning of the spectrum so that there is a constant difference of pressure, and thus of refractive index, maintained between the respective chambers as the scanning proceeds. The light beam 22 passes through a coloured filter 24, condensing lens 26, reflecting prism 28 and aperture 30 to a collimating lens 34. After passing through narrow band interference filter 36, which is tiltable as shown by the arrows to give its peak transmittance at a desired frequency, the beam passes through the etalons and lens 44 to an aperture 46 behind which is a photo-multiplier 50. To maintain a constant difference of pressure between chambers 52, 54, 56, the differential pressure is measured between chambers 52, 54 (and also between chambers 52, 56, by an exactly similar apparatus) and a mercury manometer 18, Fig. 7 having a ferrite ball 188 floating on one surface of the mercury and co-operating with differential transformer windings 190 which are wound on a spool so as to be initially adjustable up and down the manometer tube. Photo-cells 198, 200, co-operating with lamps 202, 204, act as safety devices to initiate action should the ferrite ball 188 move outside of predetermined limits. In a modification, Fig. 15 (not shown) air capacitors (268, 270), housed in the respective chambers (52, 54), are included in the arms of a bridge which is balanced when the differential pressure is at the desired value. Alternatively the balancing capacitors (266, 270), Fig. 16 (not shown) are also included in the chamber (54).

Abstract: 502,025. Locating conductors; current meters. RUHL, JUN., A., MACHTS, L., MACHTS, R., and NICKEL, B. Dec. 9, 1937, No. 24542. Convention date, May 31. [Class 37] [Also in Group XL] High-frequency apparatus for geophysical survey comprises a portable arrangement of a transmitter and receiver structurally combined as a unit, the transmitter or receiver as a whole being rotatable to effect minimum coupling between them, such adjusted position being indicated on meters. In general, a low power transmitter and highly sensitive receiver are employed, and the transmitter may be modulated. As shown, the transmitter comprises a single valve oscillator and frame aerial 1 located in a casing which is rotatable on pivot 6 by a worm 9. During transport the transmitter casing is latched in its horizontal position. Under operating conditions the receiver frame aerial 12 is in a plane parallel to pivot axis 6 and the transmitter frame aerial 1 is at right-angles to receiver aerial. Additional aerials at right-angles to 1, 12 may be employed. The receiver comprises four separately tuned high-frequency amplifier stages connected to the frame aerial 12, the last high-frequency stage including a parallel circuit for preventing back coupling. The highfrequency stages are inductively coupled at 21 to a low-frequency circuit which includes a telephone or loud-speaker receiver. A further low-frequency stage comprises a rectifier 24 and two series-connected meters 26, 26 one giving' a deflection, for example, four times that of the other for the same current, the " coarser instrument being also provided with range shunts. A continuous-current circuit 28 including a variable resistor provides a neutralizing current for setting the instrument zero. The sensitivity of the receiver can be tested by relatively adjustable plates 32, 33 connected with the frame aerial 12. The control knobs together with that for the zero setting are preferably located in the remote end wall of the cabinet to reduce capacitative disturbance. Carrying arms for the apparatus comprise projecting shafts upon which gripping tubes are mounted on ball bearings, the arms being above the centre of gravity so that the receiver aerial, for example, remains horizontal. Fig. 5 shows the meters fed from parallel-connected secondaries, each meter having its own rectifier 24. Only the meter 25 is provided with a zero neutralizing current circuit, the meter 26 having a disconnectible and variable shunt 53. For transport purposes the transmitter and frame part 5 can be detached, and can be made to slide in relation to the receiver. It is stated that in addition to locating a change in the subsoil, the direction of the course of an inhomogeneity can be determined by pivoting the transmitter around the point occupied by the receiver.

Abstract: 928,836. Dynamo-electric machines. UNITED AIRCRAFT CORPORATION. July 6, 1961 [July 22, 1960], No. 24548/61. Class 35. [Also in Group XL (a)] A magnetohydroelectric generator comprises a casing providing a duct having an inlet and an outlet, means for moving a fluid stream containing fissile material through the duct, moderator means surrounding the duct and extending a predetermined distance along the path of fluid flow, and electrode means positioned adjacent the duct. In Fig. 1 the working fluid passes through the duct 10, and then through heat exchangers 52, 56 to a pump 60, and then back through heat exchanger 52 to the duct 10. A coil 24 has its wires running parallel to the axis of the fluid flow so that it generates magnetic lines of force which pass transversely of the path of the fluid; thus the flow of fluid generates an electrical potential between electrodes 26, 28 which form part of the walls of the duct. The working fluid is heated by fission reactions in uranium, which may be in solid, liquid, or gaseous form, and may include seeding materials such as a potassium compound to enhance ionization. In another arrangement, Fig. 5, the main generator region is a drum-like device having inlet and outlet pipes 96, 98 between which the working fluid passes in a vortex motion. The drum is surrounded by a coil 104, and cylindrical electrodes 110, 112 are provided adjacent the outer and inner walls of the drum respectively. In a modification, Figs. 6 and 7 (not shown), coil 104 and electrodes 110, 112 are replaced by a pair of spiral coils and a pair of annular electrodes arranged adjacent the flat sides of the drum-like device.

Abstract: 1511208 Lifting limp plies CLUETT PEABODY & CO Inc 6 May 1975 [17 May 1974] 24755/77 Divided out of 1511184 Heading B8R Apparatus for picking and separating limp plies comprises a gripping device, e.g. wheel assembly 32 which engages a first area of the top ply 46 of a stack 34 and displaces it away from one edge; a hold-down device 38 which engages the stack 34 a distance from said edge less than, but more than half of, the displacement distance; control device for lowering the hold-down device and a mechanism for lifting the top ply. An arm assembly 31 supports a picking unit 92 which comprises the gripping wheel assembly 32. Actuator 43 is extended to pivot assembly 31 about a shaft 37 so that unit 92 touches the top ply 46 of a stack 34, then an actuator 55 is retracted to rotate the picking wheel anti-clockwise (Fig. 3) to push part of the ply 46 into unit 92 above a foot 33. Hold-down element 68 prevents extra plies being lifted and descends to its operative position only after the top ply 46 has been caught in unit 92. A shutter 35 moves to a position under the lifted ply and actuator 55 is extended to release the ply. The shutter 35 also assists in separating the required ply from following plies, and transports it to a position above a conveyer 36 at which a platform may be provided which rises through gaps 130 in conveyer 36 to receive the ply. Positioning lugs 74 on shutter 35 and lugs 76 over the conveyer 36 together with suspended drag bars 73 assist in orienting the ply as do sweep arms 78 mounted on rook shaft 134. The contact pressure on the stack 34 is adjustable using nut 87 and/or lever 111, thus allowing more than one ply to be lifted.

[Also in Group XXXIII] In an arrangement for removing heat from a hot surface such as the anode of an electric discharge tube or a nuclear fuel element, the surface is shaped to present one or more concave channels which or each of which accommodates or in part defines a tubular duct for cooling liquid, the duct having means whereby the cooling liquid as it flows therethrough is given a rotational movement such that a central cavity is formed which serves for the evacuation of vapour formed on the duct wall and induced by the centrifugal pressure of the rotating liquid to pass into the cavity. The channel formed in the surface is opensided and may either be closed by a cover to define the coolant duct or a separate coolant duct may be fitted into the channel. The coolant liquid may be caused to flow through the duct under pressure or by thermosyphon action. In the application of the invention to a tubular fuel element in a nuclear reactor such as is shown in Fig. 9 the channels are formed between heat dissipating ribs 20, the open sides of the channels being closed by cover plates such as indicated by 16 in Fig. 4, or 18 in Fig. 5 embodying deflector means 17 for imparting rotational movement to the coolant flowing through the channels. In addition the internal bore of the element is provided with a helical deflector 10. In the application to the cooling of the anode of an electric discharge tube, Fig. 4 shows cooling liquid ducts formed on the exterior thereof by grooves 14 in the anode which are closed by core members 16 having deflector means 17 thereon for imparting rotational movement to the liquid. The deflector means may alternatively comprise a helical wire or rod or a helical strip. The core member may be formed by a continuous sleeve 18 (Fig. 5) surrounding the anode. The cross-sectional area of the duct may be greatest at the vapour outlet end (Fig. 6 not shown). In a further Form (Fig. 11) an annular groove 22 may be formed within or as shown around the anode 21 the groove being closed by a cover 24 thus defining the duct to which cooling liquid is admitted through one or more tangential inlets 25, vapour being removed at 26. The surface of the groove 22 may be scored or roughened or provided with inclined projections 23.
