Title: Centrifugal pumps
IPC: F04B9/14
Filed: 1971-05-21
Abstract: 1323817 Centrifugal and reciprocating pumps ARMATURENFABRIK ERNST HORN K G 21 May 1971 [22 May 1970 24 April 1971] 16339/71 Headings F1A and F1C A hand reciprocating pump arranged at the outlet side of a motor-driven centrifugal pump is adapted to dispense predetermined quantities of liquid and is provided with shut-off means. The hand pump is used for priming the centrifugal pump and can also be used instead of the centrifugal pump when small quantities of liquid are to be pumped. The cylinder 16, Fig. 2 of the hand pump may be connected to the outlet pipe 4 of the centrifugal pump, the piston 18 being carried by a slidable discharge pipe 17 which also forms the operating handle. The hand pump may comprise a single valve 19 serving as the discharge valve, the suction valve then being formed by the foot valve of the centrifugal pump. A projection 18a having a seal ring 21 is engageable with an opening 22 to close the outlet pipe 4. In a modification, Fig. 6 (not shown), the shut-off means 18a, 22 is replaced by a spring- biased non-return valve (210) at the outlet side of the hand pump. The valve (210) can be held open by depressing a knob (212). Fig. 3 shows a hand pump in which the piston 107 is operable by a hand lever (not shown) on a spindle 114 connected by a crank 113 and connecting rod 112 to the spindle 111 of a valve 110 which is urged by a spring 120 against a seat 109 in the piston. The valve 110 opens automatically during the suction stroke and closes during the discharge stroke. When the centrifugal pump is to be used alone, the hand lever is moved slightly from the rest position to open the valve 110. In the hand pump shown in Fig. 7, the cylinder 303 is the movable member and is operated by grasping the discharge pipe 314. An inner tube 301 which is connected to the outlet pipe of the centrifugal pump carries a discharge valve 304 which is secured to the inner tube or integral with it. A piston 305 having a valve seat 306 is pressed against the valve 304 by a spring 310. A check valve (not shown) in the outlet line of the centrifugal pump serves also as the suction valve of the hand pump. An additional discharge valve 312 is provided at the entry to the discharge pipe 314. When the centrifugal pump is to be used alone, the valve 304 is opened by moving the cylinder 303 slightly to the left.

Title: Improvements in wave guides
IPC: H01P5/04
Filed: 1947-06-20
Abstract: 654,106. Wave-guides. WESTERN ELECTRIC CO., Inc. June 20, 1947, No. 16340. Convention date, July 3, 1946. [Class 40 (viii)] A wave-guide comprises a rod extending across the guide and means for varying the effective diameter of the rod. As shown, Fig. 1, an inductive reactance in shunt to a wave-guide is provided by a rod 11 extending across the guide between two movable plugs 16. One of the plugs may have an asymmetric projection 23 on its inner end. When the asymmetric plug 23 is screwed into or out of the guide, the effective position of the reactance is varied as well as its magnitude. A capacitive reactance is provided by omitting the rod. A greater range of variation in the value of the reactance may be obtained by placing it off the centre-line of the guide.

Title: Improvements in road traffic control systems
IPC: G08G1/08
Filed: 1930-05-28
Abstract: 351,703. Road signals for controlling traffic. AUTOMATIC SIGNAL CORPORATION, 205, Church Street, New Haven, Connecticut, U.S.A. May 28, 1930, No. 16463. Convention date, April 23. [Class 118 (ii).] Signals controlling the traffic at intersecting roads are operated by a timer transferring the right of way from one road to another under the control of means actuated by the vehicles. The roads are given the green " right of way " signal in predetermined order, but the control means does not allow a green light to be given to a road on which no vehicles are waiting, and the green light on any one road is extinguished either through cessation of traffic or after a certain time. The green light is returned to a road on which the traffic stream has been broken by the expiration of the time limit for a previous green light signal. The levers F, M, P, Fig. I, of switches controlling the signals on three intersecting roads are rocked in turn by cams on a shaft 91 rotated by a motor through a clutch 131, a member of which may be held, to prevent rotation of the shaft, by a pawl 18<1> operated by an electromagnet 19<1>, which is so electrically connected in a circuit, Fig. 2, that it is energized when a lever, say lever M, corresponding to a road on which a car is waiting reaches its left-hand position, as shown in Fig. 1. The rotation of the shaft 9<1> is then stopped, and the road corresponding to the lever M is given the green light. The electrical control is, however, such that if no cars are waiting on that road, the magnet is not energized, and the shaft continues its rotation and operates the next lever. Supposing a road corresponding to lever M operating contacts M1 .. M26, Fig. 2, holds the green light, and a car on road C corresponding to lever P operating contacts P1 .. P26 closes the road contact N2. The contacts of relays N, O, T are then closed to so connect time delayed relays X, W, that the operation of one or the other will cause a relay S to be de-energized. The opening of the relay S extinguishes the green light Gb on the road corresponding to lever M, lights the yellow light Yb, and energizes a time delayed relay Z. After a certain time, the relay Z opens the circuit of the yellow light Yb and the circuit of the clutch magnet 191. The contacts of lever M now move to light the red light Rb, the contacts of lever P move to the left to extinguish the red light Rc and light the green light Gc, and a circuit completed through the relays O, X, W energizes the relay S. The relay X delays the extinguishing of a green light to allow a car a certain time to cross, and relay W determines the time during which a stream of cars can hold the green light.

Title: Apparatus for Quantitative Determination of Oxygen in Gases.

IPC: G01N27/42
Filed: 1966-04-15
Abstract: 1,151,911. Determining oxygen content of a gas electro-chemically. LEUNA-WERKE WALTER ULBRICHT VEB. April 15, 1966, No.16591/66. Heading G1N. The oxygen content of a gas is continuously or intermittently determined electrolytically by passing the gas through an oxidizable metal tube 2, Fig.1, e.g. of zinc, lead, iron, antimony or cadmium, which forms the anode of a cell: a non- oxidizable cathode 4, 5 is situated inside the tube and preferably comprises a silver wire 4 round which a second silver wire 5 is wound. The cathode may alternatively consist of a single wire, multiple wire coil, crystals or small pieces of wire of e.g. gold, platinum, silver, copper or alloys or amalgams of these. The two electrodes are placed in contact with either side of a tubular fabric diaphragm 3 impregnated with an electrolytic solution e.g. of 25% potassium hydroxide, in which the oxygen contained in the gas is absorbed. A flowmeter (8, Fig.2, not shown), is provided at the outlet of the tube 2. For continuous measurements of the oxygen content of the gas, the current between the electrodes is measured by a meter (9), from which, together with the flowmeter reading, the oxygen content can be calculated. For intermittent measurements, when the total quantity of oxygen in a known volume of a sample is required, the area under the current versus time curve is calculated. The tube 1 may be coated on the outside with plastics material e.g. PVC, polyethylene or polyamide and may be spirally wound. The cell is similar to that described in Specification 1,148,052.
