Title: Ergometer
IPC: A61B5/024
Filed: 1972-03-30
Abstract: 1385382 Electro-medical apparatus E JAEGER 30 March 1972 [1 April 1971] 15107/72 Heading G1N The physical stress imposed on a person using an ergometer is controlled so as to maintain a physiological parameter at a pre-set, safe level. As shown, the ergometer consists of a moving belt 10 driven by a motor 18 which is regulated in dependence upon an actual motor speed signal U 1  and a desired motor speed signal Us, the desired signal being controlled by the value of a detected physiological parameter, e.g. pulse rate, blood pressure, pulse wave transit time. The physiological parameter is detected at 38, e.g. a microphone or electrodes, and converted to a voltage U P  which is applied to a meter 40 and/or a recorder, and also to a variable attenuator 46. The desired parameter value is set on attenuator 46, which is in series with a lamp 48. The flux emitted by the lamp is dependent on the parameter value and impinges on a photo-sensitive resistor 50 connected in series with a resistor 52. The desired signal Us is derived from the junction of resistors 50, 52. A switch 54 is provided to enable manual setting of the signal U S . The control may be applied to other ergometers.

Title: Purifying zinc vapour
IPC: C22B19/04

Abstract: 392,361. Distilling zinc. NEW JERSEY ZINC CO., 160, Front Street, New York, U.S.A.-(Assignees of Holstein, L. S. ; Great Neck, New York, and Ginder, P. M.; Palmerton, Pennsylvania, both in U.S.A.) May 27, 1932, No. 15151. Convention date, May 28, 1931. [Class 82 (i).] Zinc vapour is treated for the removal of contaminants of higher boiling-point than zinc, such as lead, by condensing part of the vapour, scrubbing the remainder of the vapour with the condensed zinc, and returning the contaminated condensed zinc to the source of the zinc vapour. The vapour from a source such as a redistillation retort 1, or a reduction retort, passes into areflux condenser or fractionating column 6 filled with refractory material 7, such as coke, and packed with heat-insulating material 9. The amount of the insulating material may be regulated to control the operating temperature. The purified vapour passes into a treatment device 13 to produce zinc, zinc dust, zinc oxide, &c.

Title: Improvements in or relating to Telecommunications Exchange Systems.
IPC: H04Q3/54
Filed: 1968-03-29
Abstract: 1,167,835. Automatic exchange systems. SIEMENS A.G. 29 March, 1968 [31 March, 1967], No. 15200/68. Heading H4K. In an exchange system comprising a switching network through which paths are selected with the aid of a simulating network, those busy contacts of the latter which are actuated on setting up a calling subscriber/register path are artificially freed when it is desired to set up a calling subscriber/junctor path so that the path search process can involve all the possible links that are already free or that will soon be made free whereby the possibility of blocking is reduced. In such a system it is assumed either that the originally seized register contains the identity of the calling and called subscribers and can transmit these to the junctors independently of the switching network or that when the register contains sufficient digits for routing the call a suitable junctor is seized so quickly (aided by the " release " of the original caller/ register path) that later digits can be accepted immediately in the junctor. The simulating network comprises the crosspoint holding network wherein busy guide (or hold) wires are marked by earth potential over closed contacts, e.g. aj bk, cl of the network. A detector Wi is associated with each AB link and as many of the BC links as emanate from a B switch on which the AB link terminates. A lock-out chain w1 ... wn is used for selecting one only of those detectors that respond in the absence of earth on its input and at least one of its outputs whereby a unique path between a known inlet and outlet is selected. It is not made clear how the ambiguities inherent in this method of selection are resolved by the detectors, but given the identity of an inlet and an outlet it is apparent that a control circuit could solve the problem. When it is desired to set up a caller/ junctor path, a relay J associated with the selected detector is brought up in order to simulate-by opening its contacts 1i, 2i-a free path in respect of the seized AB (hab) and BC (hbc) links in the caller/register path. Since the remaining BC links (hbc<SP>1</SP>) associated with this detector are not necessarily free, these are connected via contacts such as u to the detector during the path search.

Title: Powder extinguishing installation

Abstract: 954,076. Powder extinguishers. MINIMAX N.V. April 27, 1961 [April 29, 1960], No. 15232/61. Heading A5A. A powder extinguisher, Fig. 4, comprises a pressure conduit 2 leading to a powder tank 1 and bifurcating in the vicinity of pressure tanks to form a first duct connected via a reduction valve 6 and a shut off 5 to a main pressure tank 3 and a second duct connected via shut off 8 to an auxiliary pressure tank 4, shut offs 5 and 8 having a common operating rod 11. In an embodiment. Fig. 1, the powder tank 1, the pressure tanks 3 and 4 and hose racks 34 and 35 are mounted on a two wheel trailer. Since there is no reduction valve in the second duct the pressure in the powder tank 1 immediately rises to spouting valve (i.e. 15 atmos.) on operating lever 11 and the pressure from the main tank 3 is sufficient to spend the powder contents of the tank 1. The pressure duct 2 terminates in mouths 30, 31, which terminate near the intake 17 of a duct 16 leading to a connection 23 for the hoses 32, 33. The latter are fitted with stopping valves 39, 40, and also with connections to valves 43, 44, in branch pipes 41, 42, from the duct 2. Opening of the valves 43, 44, removes any powder remaining in the hoses.

Filed: 1924-06-28
Abstract: 238,047. Vains, A. R. de. June 28, 1924. Pulp, preparation of.-Lignocellulose and like materials are chlorinated by continuously feeding the pulped materials and chlorine solution to a reaction vessel from which the products of reaction are continuously withdrawn, the rate of supply of either of the reagents being varied according to the degree of chlorination desired. One form of apparatus for carrying out the. process is described in which the cellulosic pulp and the chlorine solution are continuously fed through a common inlet into a reaction vessel provided with agitators and with an outlet. Another form of apparatus is described also in which the agitators are replaced by baffles. To maintain a desired uniform degree of chlorination the rate of supply of chlorine solution may be made to depend on the pressure obtaining inside the reaction vessel, and the rate of supply of cellulosic material to vary with the output of the apparatus in which the pulp is prepared. In this modification, as shown in the Figure, the reaction vessel H is provided with a bell J which rises or falls with increase or diminution of the pressure of chlorine gas set free in the reaction, and actuates a lever L controlling a valve F through which chlorine solution from a tank A is fed to the reaction vessel. Alternatively, the bell may be arranged to control the supply of water or of chlorine to the apparatus in which the chlorine solution is prepared. The cellulosic pulp is drawn by a pump B from a vat C in which is arranged a float M adapted to actuate the regulator N of a motor 0 which drives the pump, the arrangement being such that the speed of the pump is increased or diminished as the float rises or falls. In any of the forms of apparatus described the reaction vessel is lined with a material capable of resist-. ing the action of chlorine, a suitable material being an alloy containing 70 per cent of copper, 15 per cent of tin, and 5 per cent each of lead, aluminium, and phosphorus.
