Title: Guide- and moving blades for turbines, turbine pumps, and the like
IPC: F01D5/14
Filed: 1923-05-29
Abstract: 213,154. Forner, G. May 29, 1923. Impeller blades.-In turbines, applicable also as turbine pumps, in order to facilitate the jets of liquid entering the fixed or moving blades without shock and without altering their thickness, the blades are so formed that the extensions c a, d b of the circular arcs of their concave surfaces c e, d f, Fig. 1, are touched outside the blade passage at the points a, b by the tangent at the initial points g, h of the convex surfaces g i l, h k m. The width b i of the passage is equal to the thickness of the liquid jet, the centre of curvature o of the arcs b d f, i l being located in an extension of the line b i. These arcs may have different centres of curvature along the line b i. With long blades the profile sections throughout the height of the blade are adapted to the varying angle of the jet, changing gradually from sections e c g l, f d h m, Fig. 2, at the foot to sections c<1> e<1> g' 1', f<1> d<1> h<1> m', at the tip. The points a, b for the blade at the foot become the points a<1>, b<1> at the tip In a further modification, Fig. 3, the points a<1>, b<1> fall on the concave sides a c e, b d f, and the curvature of concave sides is constant from root to tip.

Abstract: 1437641 Drilling machines ENGELHARD MINERALS & CHEMICALS CORP 29 March 1974 [29 March 1973] 14178/74 Heading B3C A drilling machine having a control arrangement for driving a drilling tool through an operating cycle of reciprocating travel including an interval of drilling into a sheet of glass, the control arrangement comprises a fluid cylinder, a piston therein connected to the drilling tool, fluid pressure means connected to the cylinder to extend the tool at a constant feed rate interval of fast travel up to a position close to the surface of the sheet and a constant feed rate interval of slow travel from said position to a predetermined depth of cut into the sheet and, adjustable timing means connected to the fluid pressure means for controlling the duration of the constant feed rate time intervals whereby to control the positions of the tool at the initiation and termination of said extension time interval to control the depth of cut into said sheet. As shown spindles A and B are reciprocated by fluid cylinders 15, 16 respectively. Spindle B is cycled first followed by spindle A. A sheet of glass is clamped to table 20 by jaw 24 which is operated by cylinder 27. The pressure of the jaw is greater during drilling by spindle B than for drilling by spindle A. The feed rates and periods are determined by digital timers and adjustable flow restricters.

Patent GB-608034-A (GB)
Title: Driving device for tele-communication instruments
IPC: H01H63/22
Filed: 1944-07-26
Abstract: 608,034. Motors. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 26, 1944, No. 14286. Convention date, July 27, 1943. [Class 35] [Also in Group XXXIX] A step-by-step motor for driving telecommunication instruments turns through one angular step for each current impulse in such a way that part of the step takes place during the current flow and the rest, taking it to the next zero position, under the influence of a permanent magnetic flux or cam mechanism, the impulse current being cut off by auxiliary means after the first part of the step has taken place. In one form, Fig. 3, a motor capable of rotation in either direction has a pair of electromagnets 83, 84 producing opposite directions of rotation and carrying windings 61, 62. The centring device comprises a permanent magnet NS whose effect on the zero-positioning polepieces 87, 88 is arranged to be counterbalanced during each step by a coil 63 on the shaft of the rotor 85. The auxiliary device for cutting off the impulse comprises an armature 72 operated by a coil 66 on the electromagnet 84 which is not in use for the direction of rotation employed. The circuit is arranged so that when a cam 81 on the rotor interrupts a pair of contact springs 64, the coil 66 is energized, thus drawing one of the contacts back into the position shown in broken lines and preventing their reclosing and causing continuous selfoperation of the machine. When the impulse dies away the coil 66 is deenergized and allows the contacts to close for the next step. Fig. 2 shows a circuit diagram, for achieving this. The impulse is applied at 50 and passes through the contact 44, corresponding to 64 in Fig. 3, energizing stator and rotor coils 41, 43 (61, 63 in Fig. 3), the relay 48 having been closed by external means. Rotation of the shaft through about 60 degrees causes the interruption of contacts 44 so that the stator and rotor current passes through a coil 46 (corresponding to 66 in Fig. 3), thus holding the contact 44 open. The coil 46 is of high resistance so that the stator and rotor are excited to a negligible degree. When the impulse dies away coil 46 is deenergized, thus closing the contacts 44 for the next operation. A friction damping device 78 may be fitted on the motor shaft to reduce the oscillations after each movement. In a modification, Fig. 1 (not shown), a separate relay takes the place of the coil 46 acting on the interrupter. A mechanically-driven machine including a cam indexing means is also described (see Group XXXIX). Specification 604,112 is referred to.

Abstract: 588,144. Electromagnetic switches. STILWELL, W. E. Aug. 8, 1944, No. 15035. Convention date, Aug. 12, 1943. [Class 38 (v)] An overload protective device actuated by the increase in magnetic flux round an electrical conductor when the current through the conductor is increased, comprises a magnetic U-shaped strap 11 which receives the conductor 14 and is bent outwards to form poles 12, 13 and a magnetic extension 17 secured to pole 12 and pivotally carrying by means of a rivet 18, an armature 20, one end of which overlies pole 13. A spring 25, the tension of which is varied by screw 26, biasses the armature 20 anti-clockwise so that a contact 24 on the rear end is separated from a fixed contact 23a. A non-magnetic shim 21 spaces the armature from the extension 17. Upon overload, the armature 20 is attracted by pole 13 and moves clockwise with a snap action imparted by a roll-spring 27. Closure of the contacts energises a solenoid which operates a circuitbreaker. In a modification, the contact 24 is arranged on the free end of the armature, the contact 23a being correspondingly moved, so that the contacts are normally closed, and open upon overload, thus de-energising a solenoil and opening a circuit-breaker.

[Also in Group XXIX] In, e.g., a rotary counter-pressure bottling machine, an automatic valve for admitting liquid to the tank 5, Fig. 1, comprises a pressure sensitive device such as a diaphragm 26 for operating a liquid admission valve 1, which responds to a pressure derived from a source of substantially constant pressure external to the tank and which is controlled by a valve device 44, Fig. 4, sensitive to liquid level in the tank. Liquid enters at 14 to the inlet of the valve 1 and passes a snift valve whereby gas in the liquid enters a chamber 13 and depresses an annular float 16 carrying a valve 15 so that the gas escapes via the valve a hollow central float guide 17 and a cock 20.

A source of pressure air is supplied at 29 past a pressure reducing valve 30 and a valve 31 to a valve chamber 32 which leads via a line 33 to a diaphragm chamber 27. The valve chamber contains a needle air-throttle valve 34 and an adjustable spring-loaded, leak-off valve 44 operated through a push rod 38 by twin floats 35 responsive to the liquid level in the tank, so that as the level falls due to the bottles being filled via pipes 11 and filling head 12, the leak-off valve closes and air pressure moves the spring loaded diaphragm to open the valve 1 and admit liquid to the tank via the inlet pipe 7 and annular conical opening 8.
