Title: Improvements in or relating to fluid pressure measuring apparatus
Inventor: SOERGEL DAVID G
Filed: 1956-04-03
Abstract: 828,220. Pressure transducer. NORTH AMERICAN AVIATION Inc. April 3, 1956, No. 10202/56. Class 40 (1). [Also in Group XIX] In a pressure transducer, the tendency to angular displacement of a pressure-sensitive tube element produces an error signal which provides an output proportional to the pressure input and also actuates a counter-torque device which enables the pressure-sensitive element substantially to retain its null position. As shown, the resultant of two pressures, one introduced at a port 3 into a torsional straight line tube 11 located in a chamber 56 which is supplied with the second pressure through a port 4, tends to rotate the free end of the tube 11 to which is connected an armature 12, displacement of which unbalances an inductive " E " pick-off 18, two coils 57, 58 of which are connected in a bridge detector. An error signal from the detector is amplified and fed to a motor 41 which operates, through a gear-train 33 to exert a torque via a spring 34 and a feedback shaft 13 to return the armature 12 to its null position, and to vary the output from two potentiometers 39, 40; alternatively, the output may be taken from across a resistor connected in series between the amplifier and the motor. Damage to the spring 34 is prevented by a spring stop 46.

Title: Improvements in die casting machine
IPC: B22D17/06
Filed: 1927-04-20
Abstract: 275,127. Lester, N. April 20, 1927. Casting - machines; metal-pouring; castings, extracting. - A die-casting machine having a pair of dies 12, 14, a melting-furnace 62 and a movable forcing-chamber 81, is provided with a fluid-operated piston, controlled by hand operated valv.es, simultaneously to move the chamber into casting or non-casting position and to close or open the dies. The piston 21, Fig. 6, is connected to a double rack 23 adapted to oscillate segments 29 and arms 30, carried thereby, and thus, by links 38, 39, move the die 14 and, more slowly, the ejectors 43. A rack 52, shown in rear view in Fig. 3, is mounted on the slide 19, Fig. 1, which carries the moving die 14, and engages a gear 55, pivoted to a bracket 53 fixed on the frame 10. This gear acts through arm 56, adjustable link 59, arm 61, shaft 91, arm 85, Fig. 10, and link 88, to move the forcing- chamber 81. The chamber is carried by links 90, 99 the latter being pivoted to an adjustable block 97. Moulds.-In its casting position the chamber engages an aligning pin 110, a pipe 109, supplied with compressed air by a valve 77, Fig. 1, and a water-cooled sprue opening. The valves for controlling the movement of the piston 21 by oil from a pump 43 are connected with a notched disc 66, Fig. 15, which when the dies are open engages a notch 70 in a similar disc 69 connected to the hand operated valves 77, Fig. 1, so that air cannot be admitted to the chamber 81. When the oil-valves have been moved to close the dies the notch 67 registers with the disc 69 and the valves 77 can be operated to admit air to the chamber 81, this movement locking the oil valves until the air valves are. returned to their normal position thus exhausting the air from the chamber 81. When the die 14 is withdrawn the casting is automatically ejected by the rods 43.

Title: Improvements relating to warp-tying machines and the like
IPC: D03J1/16
Filed: 1959-03-26
Abstract: 886,433. Warp tying machines. ZELLWEGER Ltd. March 26, 1959 [April 2, 1958], No. 10640/59. Class 142(1) The two ends of a warp tying machine mounted on telescopic legs can be raised or lowered together and one end can be adjusted separately by manipulation of a single hand crank, to enable the machine to be levelled on an uneven floor. The legs are operated by screws 16 engaging nuts 14 on the inner members of the legs; the screws carry bevel gears 17, of which the one shown meshes with a gear 18 loose on a shaft 19, whereas the gear 17 at the other end of the machine meshes with a gear fast on the shaft 19. The operating crank consists of an arm 27 pivoted to the shaft by a pin 31 and having a handle 35 similarly pivoted to it. Spring-loaded plungers 34, 37 in the arm engage flats in the shaft and the handle to hold the crank in the required configuration. As shown, the arm 27 is in contact with the gear 18, which it presses against the end of a tubular member 3 of the machine; rotation of the gear 18 is thereby prevented by friction, and rotation of the shaft 19 is prevented by friction between the arm 27 and the gear 18. On turning the arm 27 and the handle 35 through 180 degrees about their pivots 31, 40, a tooth 38 on the arm enters a notch 39 in the gear 18; the gear and the shaft 19 can then be rotated to adjust both legs simultaneously. By turning the arm 27 through 90 degrees from the position shown so that it is in line with the shaft 19, the shaft can be rotated to adjust the far leg only; the gear 18 remains stationary, since friction between it and the tube 3 is greater than between it and the shaft 19.

IPC: B60R21/34
Abstract: 106,831. Weinberg, H., and Weinberg, C. May 31, 1916, [Convention date]. Wheel guards and safety appliances.-A safety guard for the wheels of motor and like vehicles is in the form of a casing 4, Figs. 5 and 6, which comprises front, rear, and side members almost enclosing each wheel and a front curved extension 5, and has attached to it a small vertically-movable spring-pressed wheel 23 adapted normally to serve as an anti-akidding device but also, when the wheel tyre is deflated, to act as an emergency wheel and auxiliary support for the vehicle. The wheel 23 is carried by a slide 21 having formed on one side a rack 29 adapted to engage loosely with the teeth of a gear-wheel 30 carried by the casing 4. The loose engagement allows the wheel 23 vertical play under normal circumstances; but when the tyre is deflated, the teeth of the rack and gear-wheel are kept in close contact, and the wheel 23 acts in conjunction with the casing 4 as a supporting-device. The gear-wheel 30 is capable of ajdjustment in either direction by the engagement of a wrench with a square head 32, and is held against rotation in the opposite direction by one or other of two pawls 37, 38 co-operating with a ratchet-wheel 36 on the gear-wheel 30. Each of the front wheel guards carries a curved shield 14 connected to the other by a transverse bar 6, Fig. 2, and normally pressed forward by a spring 19, each shield having a tongue 16 projecting backwards through a slot in the casing 4 and carrying a brake shoe 18, which engages the wheel when strong pressure is applied either to the bar 6 or to the shields 14. The front wheel casings 4 are connected by a chain or wire mesh 7 consisting of two sections hinged together at 11, so that the lower portion 10 can be turned upwards if desired.

Abstract: 726,457. Winding thread &c. SOC. RHODIACETA. April 20, 1953 [June 17, 1952], No. 10765/53. Class 120 (2). A process for winding thread, &c., supplied at a predetermined speed substantially without twist and at a tension remaining below a predetermined value, comprises driving the take-up thread support by means of a pneumatic or hydraulic motor so arranged that its curve C resulting from plotting power consumed against angular speed of rotation is such that every point on this curve has an ordinate between those on the same abscissa, on the one hand, of the curve A of power consumed in overcoming mechanical and air resistance during winding and, on the other hand, of the curve B of total power absorbed by the assembly constituted by the support and thread when winding is effected at the predetermined tension, these last two curves A, B being obtained by plotting power against angular speed of rotation. In an example, a take-up tube 21 carried by a sleeve 22, supported by bearings on a shaft 23, and driven by a pneumatic turbine 24 is collecting acetate yarn supplied at 400 metres per minute and the winding tension is not to exceed 2 grams. Curve A, Fig. 3, is plotted from experimental data and curve B, Fig. 3, has ordinates greater than curve A by 400/60 X 0À002 = 0.013 k.g.m. (sec. The turbine 24 is then arranged such that the air flow is e.g. 0À4 litres per sec. at a pressure of 105 m.m. of water, to give a power-speed curve C lying between the curves A.and B.'
