Title: Improvements in and connected with shock-absorbing steering wheels
IPC: B62D1/10
Filed: 1934-01-16
Abstract: 432,034. Hand wheels. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Warwickshire. Jan. 16, 1934, No. 1531. [Class 80 (iv)] Shock-absorbing steering hand wheels of the type in which resilient material is interposed between the hub and the steering column are fitted with means for putting adjustable pressure on the material, which may be in the form either of annuli or of separate units disposed in pockets. The head H may be in two parts 2, 10 each of which is formed with three part-spherical pockets. Rubber balls 1 are confined in the pockets formed by hemispherical cavities 6 in the hub 7 in registration with similar cavities formed by the cavities in the parts 2, 10. The balls form the only connection between wheel and column head. Compression is effected by the bolts 9 which unite the two parts of the head. Alternatively the hub instead of the head H, may be in two parts ; also the balls may be compressed by special diametral screws. Stops may be provided to limit the compression. Fig. 12 shows inner and outer rubber annuli 23, 24, forced apart by metal rings 25, 26. One solid ring R may be used as shown in Figs. 14 and 16 or an inflatable tube 34, Fig. 15. In another form, Fig. 20, pressure is put on the rubber ring 42 by means of a ring 10 and a central knob 46 threaded on the boss 43 of the column 44. The steering wheel W may be placed over the column H, Fig. 21, instead of surrounding it as in the previous examples, and the connection made by cylinders 52 of the section shown, the ends being expanded somewhat as shown in Fig. 12.

Abstract: 1,093,592. Tilting metallurgical converters. VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE A.G. Jan. 13, 1965 [Jan. 13, 1964], No. 1535/65. Heading F4B. In a self-adjusting transmission for tiltable converters, the detrimental effect to the driving pinion 4 and the trunnion gear attached to the furnace, of relative movement between the two is obviated by mounting the pinion shaft in a bearing bracket 9 that is attached to a rotatable base 10 supported by a guiding member 12 which is itself slidable along rails 15 inserted in the framework of the converter 6. Balls, rollers 13 or the like are used between the annular flange 11 of the rotatable base 10 and the guiding member 12 and also between the supporting noses 16 of the guiding member 12 and the groove 14 formed in the rails 15. In an alternative arrangement the bearing bracket 9 may first be mounted on a slidable table which is then attached to a rotatable base. The pinion may be made of a softer material than the trunnion gear and/or any idlers in mesh with the pinion.

Abstract: 679,740. Blood - cell counting-apparatus. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Dec. 27, 1950 [Jan. 20, 1950], No. 1622/50. Drawings to Specification. Class 81 (ii). In blood-cell counting-apparatus of the type in which an electrical impulse is received from a scanning head on the passage of each blood cell, amplitude selective means are incorporated between the scanning head and the counter so that only impulses above a predetermined level are effective for actuating the counter. One electronic relay circuit which produces a pulse of constant shape on the application of each impulse having an amplitude above a critical level is the Schmitt trigger circuit and this is conveniently connected between the photo-cell amplifier and the dividing and counting apparatus. Such an arrangement prevents false operation of the counting device by valve " noises." Specification 679,741 is referred to.

Filed: 1972-01-13
Abstract: 1340635 Measuring mach number GENERAL ELECTRIC CO 13 Jan 1972 [30 April 1971] 1738/72 Heading G1N To determine the Mach number of the flow within a duct of a gas turbine engine pressure measurements are taken and applied to a circuit to provide the relationship M = P T  - P S  Ps where M is Mach number, P T  is total pressure and P S  is static pressure. As shown in Fig. 2 a value of P T  - P S  is obtained from a strain gauge bridge 40 to provide a signal E i  applied to an operational amplifier 46 having a gain G. A feedback loop with a factor H includes a strain gauge bridge 42 whose output is proportional to the static pressure P S . Thus since in general E o /E 1  = G/1+GH and E 1  α P T  - P S ; H α P T ; and G >> 1 then E o  = E 1  G/1+GH = (P T -P S )G/1+GP S  = P T -P S /P S    A non-lineal temperature compensation network 72 maintains the zero balance of the circuit P t  = P s  over a broad range of temperature, and a capacitor 82 provides frequency compensation. A more complex circuit is disclosed, Fig.3, (not shown). Whereby inaccuracies due to mismatch of resistors is eliminated.

Title: Improvements in or relating to devices for measuring displacements
IPC: G01D5/38
Filed: 1959-01-19
Abstract: 906,101. Electric selective signalling systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 19, 1959 [Jan. 21, 1958], No. 1885/59. Class 40 (1). A device for measuring the displacement of a movable member with the aid of a diffraction grating 3 coupled to the member and having the lines at right-angles to the direction of movement, there is provided a stationary optical device comprising (according to a first embodiment of the invention) a lens 5 and a plane mirror 6 for projecting an image of the grating which moves in the opposite direction back on to the grating itself. The light passing back through the grating fluctuates in intensity as the grating moves and is detected by a photoelectric cell 8 to produce impulses which may be applied to a counter 8 to determine the extent of the displacement. Lens 2 produces an image of light source 1 on the grating, lens 4 produces an image of lens 2 at infinity and mirror 6 is located in the focal plane of lens 5. The returned light is directed to the photo-electric cell by semi-transparent mirror 7. A modification, Fig. 6 (not shown), dispenses with mirror 7 by inclining the source and photo-electric cell to the optical axis of the system. In another embodiment, Fig. 2 (not shown), the plane mirror is replaced by a roof mirror prism which is turned slightly so as to cause the lines of the original grating and its image to cross to produce a moirÚ pattern whose dark zones move in the direction of the grating lines. Two photo-electric cells are positioned to produce outputs with a phase difference of 90 degrees and permit a distinction to be made between positive and negative displacements. In a modification of this arrangement, Fig. 3 (not shown), a mirror having two or more angularly displaced plane parts is employed. In a further modification, Fig. 4 (not shown), there is employed either a continuous mirror surface formed of relatively displaced elements or an analogous lens in conjunction with a plane mirror. The invention may be employed with a phase-type grating, i.e. a wholly transparent grating of cyclically varying thickness, by masking out selected diffraction maxima, preferably the zero and first order maxima. If this is done the light intensity fluctuates sinusoidally. The masking is effected by arranging the reflecting surface employed in the stationary optical system described above to be reflecting only over the regions occupied by the desired maxima.

The plunger 68 passes through a slot (88), Fig. 4 (not shown), in one leg 50 of an L-shaped arm 40. The other leg 45 of the arm 40 extends into the tunnel 24 and is engaged with the front edge of the cartidge 24 by a spring 49. The slot (88) has sections (90), (94), Fig. 2 (not shown), which are smaller and larger respectively than an enlarged portion 82 of the plunger 68. As a cartridge 14 is removed and the plunger 68 is made to retract, the arm 40 slides on guide posts 42, 44 and the smaller slot section (90) thus engages the enlarged portion 82 to keep the plunger 68 retracted. Contacts 36 detect conductive strips on the tape 16 to automatically position the head 32 with respect to the various tape tracks.

Abstract: 905,396. Two-way transmissions. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 19, 1959 [Jan. 22, 1958], No. 1912/59. Drawings to Specification. Class 40 (4). In a two-way amplifier comprising two oneway amplifiers connected to respective lines via hybrid transformers, the input and output impedances of the amplifiers are arranged so that substantially the whole of the energy coming in is dissipated in the line-balancing network. In these circumstances the impedance presented by the amplifier to the line is substantially that of the balancing network so that the line and amplifier impedances are perfectly matched and no reflections take place. To satisfy the required condition the amplifiers are required to have very high input impedance and very low output impedance or vice versa. Suitable amplifiers in the respective cases may be emitter follower transistor amplifiers or grounded base transistor amplifiers.

[Also in Group XXVI] In an apparatus for producing a supply of working fluid for the operation of a prime mover 12 by decomposition of a mono-fuel, a conduit 11 leads from a breech 10, in which a charge of deflagrant such as cordite may be fired, to the prime mover. The conduit is provided near the breech with an inlet 13 for the supply of mono-fuel thereto, combustion of the mono-fuel being initially caused by the hot combustion products produced by firing the cordite in the breech. Mono-fuel is supplied from a tank 14 to the space below the piston 19 of the pressure intensifier 17, the space above the piston 19 being connected by a pipe 21 to the conduit 11. The fuel flows from the intensifier 17 through the supply pipe 18 to the mono-fuel inlet 13 on the conduit 11. The conduit 11 thus acts as a mono-fuel reaction chamber. The prime mover 12 may be a turbine which is used for starting a gas turbine or other internal-combustion engine and the invention is particularly applicable when the breech 10 has to be located at some distance from the prime mover 12. The intensifier 17 may contain sufficient mono-fuel to provide one start; a fuel pump may be used instead of the intensifier 17. Specifications 784,121 and 787,571 are referred to.

Abstract: 1491802 Trailer brake control; braking systems responsive to deceleration TEKONSHA ENG CO 20 Jan 1975 [9 Dec 1974] 2412/75 Headings F2F and F2E A brake controller 11, Fig. 4, for brakes in a towed vehicle and for connection to a source of electrical energy comprises a light-sensitive monitor 37, inertially-operable means 12, 32, for attenuating light to the monitor from a light source 35 in response to the degree of inertial imbalance, and a power circuit connected to the monitor and arranged to transmit, upon actuation, a constant-width pulse at a frequency proportional to the amount of light sensed by the monitor as determined by the inertially operated means, for actuating the brakes in the towed vehicle. The invention is associated with trailer brakes 20, Fig. 4, though the apparatus (apart from the stop lights) is located in the towing vehicle. When the brakes (not shown) of the towing vehicle are applied, a line 59 in the control circuit 11 is energized by closure of the stop light switch and through connector 79. At the same time, a shutter 32 forming part of a cantilever beam 12 is moved by inertia to permit light from the source 35 to fall on the photosensitive target 37. The signal thereby generated is amplified, and further processed in an integrated circuit 49 to produce pulsing of a silicone power transistor 44, whereby uniform-width brake-operating pulses 80, Fig. 6, are conveyed from a battery 16 along line 18 and connector 77, Fig. 4, to the electrical, or electro-pneumatic or -hydraulic, brakes 20. The frequency of the pulses is proportional to the degree of inertial imbalance. As an alternative to 'stoplight' energization, and light-actuation line 59 may be energized, and a signal provided, by battery 16 through a manual over-ride switch 45; a gain-control potentiometer 47 may be provided. A probe circuit 25, Fig. 4, serves to indicate intermittently the presence of, e.g. a short circuit at the brake load 20 and to suspend operation of the control circuit 11 until the fault is corrected. The elements of circuit 25 are all those represented by heavy black lines, together with a resistor 53 which is common also to circuit 11. The dashed line between a coil 65 in line 18 of circuit 11 and a reed switch 66 of circuit 25 indicates that the coil magnetically surrounds the reed switch. When a fault causes the brake current to rise to a spike, e.g. 82, Fig. 6, coil 65 closes switch 66 so that the junction between a capacitor 67 and the base of a transistor 68 is grounded; transistor 68 then grounds a junction 72 and line 71 with the results that power transistor 44 is turned off so the current in line 18 rapidly decays from value 82 to zero, Fig. 6, and that lamp 74, or an audible or tactile alarm, is energized to warn the vehicle operator. The peaking and decay of the brake current continue until the fault is corrected.
