Title: Improvements in and relating to echo sounding apparatus
IPC: G01S15/50
Filed: 1939-01-09
Abstract: 570,133. Echo-sounding apparatus. HUGHES & SON, Ltd., H., SPROULE, D. O., and HUGHES, A. J. Jan. 9, 1939, No. 681. [Class 118 (ii)] In apparatus particularly for use on aircraft, an oscillator of which the frequency changes progressively after the emission of the primary sound is connected to a telephone receiver on the receipt of the echo, so that the pitch of the note heard indicates the echo time and hence the altitude. In Fig. 1, a thermionic oscillator c is governed by a variable condenser g, which has its movable plates coupled to the shaft of the sound emitter and so shaped that its capacity increases steadily after a sound pulse is emitted to a maximum just before the next sound pulse and then decreases rapidly. The oscillator is coupled to a telephone receiver o by a thermionic valve l which is normally biassed below the cut-off and is rendered effective when sound arrives at the receiver a. The receiver o therefore gives out a standard note when a sound pulse is emitted and a note of characteristic pitch when the echo arrives. The circuit of the receiver a may be disabled while the capacity of the condenser g is decreasing. Alternatively, the condenser may form part of a relaxation oscillator. Fig. 6 shows an arrangement of this kind in which a series of capacities are brought into circuit with a neon tube p in succession by a switch arm u rotating in synchronism with the sound emitter. The oscillations are applied to the valve w upon operation of a relay v controlled by the receiver a. The capacities may be chosen so that the oscillator generates notes on the diatonic scale.

Title: Improvements in and relating to vehicle brake assemblies
Inventor: COCHRANE ROBIN ADAM
IPC: F16D53/00
Filed: 1965-01-07
Abstract: 1,137,062. Drum brakes. GIRLING Ltd. 5 Jan., 1966 [7 Jan., 1965], No. 704/65. Heading F2E. In a vehicle brake assembly, a pair of friction elements 32, 38 are carried on radially opposed sides of a rotatable brake drum 20 in a housing or calliper member 10 which straddles the drum and is pivotally mounted about an axis 13 substantially parallel to the drum axis. The pivotal axis of the calliper member 10 is situated on the leading side of the calliper member relative to the normal direction of rotation 48 of the drum 20. In operation, when fluid under pressure is introduced into fluid inlet 26, a piston 24 operating in brake cylinder 22 is urged outwardly to bring the inner brake pad 36 against the inner surface of the brake drum while the reaction experienced by the inner arm 18 of the calliper member 10 pulls the outer brake pad 42 against the outer drum surface. Due to the pivotal mounting of the brake asemsbly on the pin 13 and with the drum 20 rotating in the direction of the arrow 48, the inner brake pad 36 tends at its leading edge to pull into the drum to produce a self-wrapping or self-servo effect to augment the braking force applied by the pressure fluid introduced into the cylinder 22. Since the brake assembly is pivotally arranged on a single pin 13 the brake pads 36 and 42 are made with tapered sections to compensate for uneven wear. An automatic adjusting device is provided between a web 12 of the calliper member 10 and the brake back plate 50 (Fig. 3). The automatic adjusting mechanism comprises a stem 54 provided on the brake back plate 50 on which is mounted a friction disc 56 urged by means of the spring 58 against a web 12 of the brake calliper member 10 to frictionally maintain the web in its initial position relative to the brake drum 20. In a modification (Figs. 4 and 5, not shown) improved brake performance is achieved by facilitating the servo action of the inner friction element 32 by pivoting the friction element about its trailing edge.

Title: Production of acetylene, or acetylene and ethylene, by partial oxidation of hydrocarbons
Inventor: DANZ WILLI
IPC: C07C4/02
Filed: 1963-01-08
Abstract: In the production of acetylene by the partial oxidation of hydrocarbons having molecular weights in the range 60-110, the separately preheated hydrocarbon and oxygen reactants are mixed in a mixer with a residence period below 0.1 second, then passed through a gas distributing block into a reaction chamber, the velocity of the gas mixture immediately before entering the gas distributer being more than 5 metres per second, preferably more than 10 meters per second.  Times and speeds relate to conditions at 0 DEG  C. and 760 mm.  The speed of the gases through the channels of the gas distributer is usually above 20 metres per second. Preferably a hydrogen-containing gas is added to the hydrocarbon, e.g. residual gas from the process.  By introducing additional gaseous or liquid hydrocarbon into the reaction zone ethylene is also formed.  The process is particularly applicable to the partial oxidation of naphthas, and the preheating temperature may be 600 DEG  C.

Filed: 1984-08-23
Abstract: A supervisory assembly incorporates a sensing means operatively associated with a TV set, so that one of the options available to the user is that when the sensing means detects someone it responds by altering the TV output. For example it may blank the screen, cut the TV power supply, or use the TV to make an alarm noise. 
<??>The sensing means has a detecting device (1), the output of which passes through a signal processing circuit (2) so as to operate a switch element (4). The switch element can operate a TV control means (6), to affect the TV output. Other, conventional, alarms (5,7) may also be operated by the switch element (4). 
<??>The assembly has use as a burglar alarm, and also for warning that someone is closer to the TV than a safe watching distance. In the latter case it is useful if the assembly's response is delayed slightly, so as to prevent it from giving the alarm when e.g. someone changes TV channel. 
<??>The sensing means may operate by emitting a signal (eg. ultrasonic) and detecting any reflection of it.

Title: Optical scanning device
Inventor: MORIMOTO YASUAKI
IPC: G11B7/1365
Filed: 1995-05-04
Abstract: An optical scanning device comprises a laser which produces a light beam. The light beam is coupled by means of a half-silvered mirror (HS) to a recording medium (CD), and from there it passes through the half-silvered mirror (HS) and is reflected onto a photodetector (PD). The light beam is distributed over the photodector (PD) by a convex lens located behind the half-silvered mirror (HS). The convex lens, which is expensive and must be precisely adjusted, can be dispensed with. To this end, a transparent plate (P) is arranged between the half-silvered mirror (HS) and the photodetector (PD) at right angles to the half-silvered mirror (HS). To prevent the beam shift due to the half-silvered mirror (HS), the plate (P), for example a plate made of a material such as glass and having the same thickness as the half-silvered mirror (HS), is glued to a front face of the half-silvered mirror (HS).

Title: Foam stabilizer for urethane foam
Inventor: YOSHIDA TAKAAKI
IPC: C08G18/00
Filed: 1988-01-04
Abstract: PURPOSE:To improve extension of a liq. when a urethane stock soln. is expanded and moreover to make it possible to carry out a uniform foam stabilization, by regulating MW to be small and in a specified range and providing a structure wherein a phenyl group or an ester group is furthermore added. CONSTITUTION:A foam stabilizer for a urethane foam is obtd. by providing a molecular structure wherein a polyether and an alkyl group are added to a polysiloxane, a small MW of 3,000-5,000 and a molecular structure wherein furthermore a phenyl group is added to said polysiloxane (e.g., a compd. of formula I) or an ester group is added thereto (e.g., a compd. of formula II). As said foam stabilizer has a small MW, the viscosity of a urethane stock soln. wherein the foam stabilizer is added is not so high and extension of liq. is improved when the urethane stock soln. is expanded, to produce a sufficient vol. expansion. Moreover, as the structure contains the phenyl group or the ester group, the compatibility with a polyol contg. a phenol group as one of the main components of the urethane stock soln. is excellent. Its dispersibility in the urethane stock soln. is thereby improved and it exhibits a uniform stabilization effect over the whole urethane foam to improve the physical properties of the urethane foam.
