Title: Hydrokinetic braking systems
IPC: F16D65/78
Filed: 1974-05-14
Abstract: 1464372 Cooled hydrokinetic brakes HAWKER SIDDELEY DYNAMICS Ltd 14 May 1974 [14 Feb 1973 4 April 1974] 7174/73 and 14966/74 Heading F2E A hydrokinetic brake system comprises a brake housing 1, Fig. 1, a rotor working within the housing, a substantially-sealed header tank 6 at a higher level, a comparatively-wide-bore downcomer pipe 8 extending down to an inlet flow control valve 5 for admitting liquid from the header tank 6 to the housing 1 and the rotor, means (e.g. lever 14) for varying the valve setting in accordance with the degree of braking required, a return pipe 10 for leading liquid from the bottom of the housing 1 back to the header tank 6, a non-return valve 9 for admitting liquid from the housing to the return pipe, a heat exchanger 11 in the downcomer pipe or, as shown, in the return pipe 10 for cooling the liquid, a narrow-bore vent pipe 13 extending from the brake rotor in the housing up to the space above the liquid in the header tank, and a valve or variable restrictor 12 in the return pipe 10 (upstream of the heat exchanger when the latter is located in the return pipe). Fig. 2 (not shown) differs from Fig. 1 only in having the heat exchanger in the downcomer pipe 8. In Fig. 3 an exhauster pump 17 is connected at 16, 15 to the housing outlet connection 3 and discharges through a pipe 18 into the header tank 6: the pump may be run only when it is necessary to remove residual liquid from the brake and reduce the pressure therein to a partial vacuum (to reduce high-speed air-drag). With pump 17, a valve 19, linked to valve 5, must be added in vent pipe 13, so that with both valves closed on brake release, pump 17 can perform its intended function. A spring-opened valve 21 in a connection 20 permits thermosyphoning when the brake is off. Either of these two refinements may be omitted. In Fig. 4 (not shown), pipe 20 is wider, valve 21 is replaced by a pump and, to the right of it, a Venturi, pump 17 is replaced by a non-return valve between pipes 16 and 18, and pipe 18 terminates at the Venturi throat. Fig. 5a (not shown) differs from Fig. 1 only in having a thermostatically-controlled valve (see below) in place of restrictor 12 in return pipe 10, and in having the braking-torque-demand lever 14 coupled to an hydraulic or pneumatic actuator controlled by a spool valve or other servo-regulating device forming part of the vehicle primary brake system and operated by a pedal. The thermostatically-controlled valve (Fig. 5b, not shown) has a fixed orifice and an additional annular orifice which provides rapid release of liquid and therefore lessened heat generation above a predetermined temperature. The servo-controlled actuator may be coupled to the conventional hydraulic brake circuit so that when the pressure in brake 1 or the temperature at the thermostatically controlled valve becomes excesssive, the conventional brakes take a greater proportion of the load (Fig. 5c, not shown).

Title: Improvements in or relating to unidirectional devices or detents
IPC: F16D67/00
Filed: 1930-06-11
Abstract: 356,651. Locking rotary elements. DEMOCRATIS, A. J., 38, St. Augustine's Road, Camden Square, London. June 11, 1930, No. 7534/31. Divided on 347,576. [Class 80 (iv).] A device for cutting out alternate oscillations of a shaft driven by a rocking member and thus converting the motion into a rotary one comprises an eccentric b fast on the shaft, a ring c on the eccentric, arms d connecting the ring with stop devices and a cam o on the shaft for actuating the stop devices. In the simplest form, Fig. 1, the arms are connected to pistons g, h, i, in cylinders having valves actuated by rods operated by the cam o. Liquid is admitted to the cylinders and discharged therefrom by the valves so that the consequent thrusts on the eccentric b render the rotation of the shaft a unidirectional. It is preferred to substitute solid stops for the liquid and rocking arms with eccentrics for the pistons. Thus the arms d, Fig. 4, are pivoted to rocking arms y carrying eccentrics z<1> against which are appropriately opposed screws u working in nuts t. The screws are turned by means of the action of a toothed face x of an arm q on helical teeth w on the stem of the screws, the arm being rocked by links p, p<1>, p<2>, p<4>, the last of which bears upon a cam o or o<1> on the hollow shaft a. The cams are mounted on a sleeve a<1> which rotates with and is slidable on the shaft a, the use of one cam causing motion in the reverse sense to the other. In a form suitable for use with the variable-speed gear described in Specification 347,576 the eccentric b is replaced by two eccentrics 1, 2, Fig. 5, working on roller bearings. The eccentric 2 is connected by a pin 6 and link 7 with a crank arm 8 on the shaft a. When the ring c tends to move in a radial direction against the action of one of the rods d it will be restrained, while being free to move in the opposite sense.

Delivery of stamps from strips.-In a vending- machine for stamps of the type in which a hand. operated slide 2 serves to push the coin into the bottom of a storage receptacle 1 at the conclusion of the inward movement, and to operate the stamp-delivery mechanism during the return movement, and in which a projection on a spring- controlled detent limits the inward movement of the slide unless a coin 16 is present to lift the detent by engaging a bevelled projection, means are provided for preventing effective inward movement of the slide if the detent is in the raised position prior to such inward movment. Coin action, mechanical connexion, fraud preventing; returning coin.-A guard 10 on a spring- controlled lever 11 is held normally below the path of the slide 2 by the bevelled projection 6 on the spring-controlled detent 7, so that the coin 16, as it lifts the detent to remove the projection 5 from the path of the slide, passes over the guard and maintains it in the depressed position. If however the detent has been lifted by a. wire or other means, the guard 10 rises through an aperture in the base-plate 3 into position to engage the slide, or the coin, if one is present, and prevents further inward movement. The spring 9 controlling the detent 7 is stronger than the spring 14 controlling the guard 10.

Abstract: 1454637 Measuring velocity electrically INTERNATIONAL BUSINESS MACHINES CORP 22 Feb 1974 [12 March 1973] 8069/74 Heading G1N The velocity with which a transducer head travels radially across successive tracks of a rotating disc in a disc drive is measured by processing the radial position signal developed in the head. The position signal 30 Fig. 2 has a triangular waveform, A of Fig. 3, which is compared at 53, 61 with a positive and negative reference value, and combined to form a timing signal 68, E of Fig. 3. The position signal 30 and its inversion are differentiated at 79, 80, dropped by the timing signal 68 and summed at 85 to give a discontinuous velocity signal 90, I of Fig. 3, on line 86, which forms one input to a processing unit 40, Fig. 1 comprising an amplifier 43 with a negative feedback loop whose time constant is switched by the inverted timing signal applied on line 49. During the pulses of the velocity signal 90, switch 47 is closed and the time constant of the feedback loop is low, whereby the unit 40 acts as a low pass filter: during the intervals between the pulses of signal 90, switch 47 is open and unit 40 acts as an integrator for a nominal acceleration signal 33 derived from the current taken by the servomotor driving the transducer head. Thus the output on line 95 is a continuous velocity signal, part derived by differentiating the position signal and part derived by integrating an acceleration signal.

Title: Optical distance measuring methods and apparatus
IPC: G02B6/04
Filed: 1972-02-22
Abstract: 1386007 Photo-electric distance measurement COMPTEURS SCHLUMBERGER 22 Feb 1972 [22 Feb 1971] 8078/72 Heading G1A [Also in Divisions G2 and H4] A distance measuring apparatus uses a device responsive to the amount of light received thereby and includes a first optical light guide arrangement which transfers light from a coherent light source and directs it towards a reflecting surface at a non- zero angle of incidence and a second light guide for transferring light reflected from the surface to the light responsive device which thus produces a signal corresponding to the distance between the reflecting surface and the emitting surface of the first light guide. In a system measuring the thickness of a sheet of float glass in a manufacturing process Fig. 11, a laser produces a parallel beam of light 54 which enters optical fibre bundle 50 at face 50Y with an incident angle #. The light emerges from surface 50Z as a hollow cone-shaped beam of half-angle #. See Figs. 4 and 4A (not shown). Receiving optical fibres 52 can only receive light reflected from the surface of the glass 70 while the fibres 62 receive only light reflected from the surface 73 of the molten tin 71 See Fig. 13 (not shown). The difference in the output signals from photodiodes 53, 63 is a linear function of the thickness of the glass sheet. The displacement of the receiving fibres from the transmitting fibres predetermines the distance from the glass at which the received light intensity is a maximum. Thus by arranging a series of annular receiving surfaces adjacent one another a wide range of thicknesses can be measured. The response of the receiver to varying distance from the reflector Fig. 8 shows a sharp peak with positive and negative slopes either side, these slopes are equal in magnitude for equally sensitive receivers (determined by cross-section of receiver bundle, gain of receiving amplifier etc.) Thus if the negative portion of one receiver coincides with the positive portion of a slightly displaced receiver, the sum of their outputs remains constant if the reflectivity of the surface remains constant. The summed output can be used to measure the reflectivity directly or to adjust the thickness measuring receivers. The optical fibre bundles may be arranged side-by-side in a circular or rectangular tube, concentrically, sandwiched or the individual receiving elements may surround the transmitting bundle Figs. 6A and 6E (not shown).
