Title: Improvements in artificial limbs
IPC: A61F2/58
Filed: 1921-07-21
Abstract: 184,356. Banks, G. W. July 21, 1921. Limbs, artificial.-Relates to those in which jointed fingers of a rotatably mounted hand are moved in unison by the direct action of a rack and pawl situated in the forearm and operated by cords from a point above the elbow, and comprises means to permit the flexure of the elbow joint with the hand gripping any desired object. A pivoted pawl 5, Fig. 2, is normally held, when the hand is open, in a retracted position over a rack n by a compression spring 5b, the tail-piece 5<a> of the pawl being connected by a strap 6 to a point above the elbow, whereby in straightening the arm, causing retraction of the rack n, through the strap q, closing the fingers and thumb, the pawl 5 is caused idly to engage the rack so that on subsequent bending of the arm, owing to the tendency of the springs in the finger joints to draw the rack forward, it is held fast by the pawl so that the fingers are locked in the closed position. In a modified form, Fig. 5, the pawl .is held in normal engagement with the rack by a spring in tension and is withdrawn from engagement bv the wearer's natural hand. The hand is bent slightly forward at the wrist joint when the arm is bent.

Abstract: 1284172 Buckle AEROQUIP AG 24 April 1970 [14 May 1969] 19886/70 Heading E2A A buckle 11 has a body 12 having a central pressure bar 13 and sides 14, 15 which support a bar 16 having a strap 17 attached thereto, support a roller 37, support a pin 38, and which support a pin 19 having a member 18 pivotally mounted thereon. The member 18 is provided with arms 21, 22 having a number of rows of teeth 23 thereon, the rows being spaced with the same pitch as cross-threads 24 of a strap 25 which is to be secured by the buckle. The arms 21, 22 are urged towards the central portion 13 of the body 12 by means of a spring 27. The pin 19 also rotatably-supports a handle 28, a portion 29 thereof being located between the arms 21, 22 of the member 18, and shoulders 31, 32 thereof being engageable with shoulders 33, 34 formed on the arms 21, 22 respectively. The handle 28 is urged towards the pressure bar 13 of the body 12 by means of a spring 35 which is mounted on the pin 19, and is received in recesses 36 formed in the sides 14, 15 of the body 12 so as to be flush therewith. In order to attach a strap 25 to the buckle 11, the handle 28, and consequently the member 18, is moved to the position shown in Fig. 3, the strap is passed under the pin 38, under the member 18, around the roller 37, then back under the member 18 and finally under the pin 38. The handle 28 is then released and the strap is drawn taut by pulling the upper layer thereof. The tension in the lower layer is transmitted to the upper layer around the roller 37 and the member 18 is urged more tightly against the strap. The latter may be released either by moving the handle 28 direct or by moving the handle 28 by means of the free end of the strap, as shown in Fig. 3.

Abstract: 443,336. Integrating - apparatus. MAUZIN, A. E., 69, Boulevard Saint-Michel, Paris. July 17, 1935, No. 20401. Convention date, Aug. 3, 1934. [Class 106 (iv)] [See also Group XX] The cant of rail. roads is determined by integrating the warp of the track with respect to the distance traversed by a vehicle moving over the track, From the centre of each of the four wheels of the vehicle a vertical cable may be stretched, the four cables being led over pulleys and collected near an integrator, Fig. 3. The cables from a pair of diagonally opposite wheels are connected to the ends of one lever and the remaining pair to the ends of another lever. The centres of the two levers are connected by a third lever, the movements of which are transmitted through parallelogram linkages to a frame 27 sliding in sleeves 27<1>. The frame 27 carries on pivots 25, 26 an inner frame 22 in which is mounted on pivots 23, 24 a light sphere 21. The latter rests on a disc 28 geared to an axle of the vehicle. Since the frame 27 and sphere 1 are moved away from the centre of the disc 28 by amounts proportional to the warp, the frame 22 will be rocked on its pivots 25, 26 by amounts proportional to the cant. A rod fixed to the frame 22 engages a fork on a recording arm 31 pivoted at 32.

Abstract: A ceramic article is obtained by mixing silica and/or one or more metal oxides with one or more metals which includes a metal capable of undergoing autothermic firing with one or at least one of the oxides and bring a metal different from the metal of such oxide, compacting, shaping and heating the mixture under conditions conducive to autothermic firing, the proportions of the reactants being such that not all of the oxide is reduced and free silicon or metal, if liberated from the oxide, is uniformly distributed throughout the article.  Up to 50% of a chemically unreactive combustible e.g. wood and/or anthracite may be included for additional porosity and when two mixtures having differing amounts of combustible are placed adjacent to each other and fired, an article having different zones of porosity is obtained. Oxides specified are those of aluminium, chromium, magnesium, titanium and thorium e.g. bauxite, chromite, chromia, grog, ilmenite, magnesia, mullite, sillimanite, thoria and titania, p  whilst aluminium is the preferred metal.  Silicon carbide may also be present, as may also ball clay, china clay and fireclay, the fireclay may even be used as the oxide component.  The article may be further heated in an oxidizing atmosphere.  The first Provisional Specification includes the oxides of tin and nickel.

Title: Fluid pressure winch control circuit
IPC: B66D1/44
Filed: 1974-05-09
Abstract: 1456256 Fluid pressure winch control circuits POCLAIN 9 May 1974 [25 May 1973] 20604/74 Heading B8B A control circuit for a winch (not shown) coupled to a fluid pressure motor 7 is shown in the configuration particular to unwinding of the winch as when a trawl net (not shown) is being paid out. Fluid from a tank 3 is fed through pipe 4 at pressure PA (Fig. 3) and pipe 10 to chamber 8 of the motor 7. Fluid from chamber 9 of the motor 7 at pressure PR is fed by pipe 11, and pipe 18 to the tank 3. A first calibrated discharge valve 19 (set at 150 bars) and a second calibrated discharge valve (set at 100 bars) are arranged in the pipe 18 and a tie-pipe 22 with a constriction 23 connects the pipe 4 to a point in the pipe 18 between the two valves 19, 20. Also shown in the circuit are a flow limiter 12 (not essential) acting in known manner to limit the motor speed and a third calibrated valve 21 (set at 10 bars). When the motor 7 is rotating at slow speed, O to N2 (Fig. 3), the flow from the pump 1 exceeds the requirements of the motor 7 and the excess passes to the tank 3 through tie pipe 22 and constriction 23 and valves 20, 21. At very slow speed (less than N1) the load loss created by the constriction 23 is greater than the calibration pressure of the valve 19 and the motor torque is then positive. When the speed of the motor driven by the trawl net lies between N1 and N2 the load loss due to the constriction 23 is less than the calibration pressure of the valve 19 and the motor torque is negative corresponding to braking the motor 7. When the speed of the motor 7 driven by the trawl net lies between N2 and N3 the pump flow is insufficient and the motor requirement is made up by the return flow from the motor passing through pipe 22 and the constriction 23. In the limit, beyond N3, between N3 and N4 closure of the speed limiter 12 brings about a very considerable increase in the pressure PR causing powerful braking of the motor 7.
