Title: Improvements in radiation analyzers
Inventor: WILLIAMS VAN ZANDT
IPC: G01N21/37
Filed: 1952-06-24
Abstract: 756,729. Radiation analysers. PERKINELMER CORPORATION. June 24,1952, No. 15890/52. Class 40 (3). In a gas analyser of the type in which twin beams of radiation, e.g. infra-red, are used for the determination of a number of gases with overlapping absorption bands, and in which are apparatus is made responsive only to the wanted gas by adjustment of the quantity of radiation in one stream and by including partial pressures of the unwanted gases in the detectors the initial zero reading of the apparatus when in the condition to read variations in the wanted gas pressure are eliminated by the portion of a third beam of radiation which may be added to the smaller beam entering one of the detectors. An example of the type of apparatus is described in Specification 675,158. As shown, radiation from a source 11 passes through a chopping plate 40, a cell 13 containing the sample under test and a filter cell 16 and is then split into two beams in each of which is a screwadjusted shutter 22, 23. Each beam then passes to one of detector chamber 24, 25 which contain both the wanted gas and the unwanted gases. In one of the beams, a compensator cell 18 containing an inert gas is inserted and in the other a sensitizer cell 20 containing the wanted gas. The Specification referred to above describes how by adjustment of one of trimmers 22, 23 and of the partial pressures of the unwanted gases in the detectors the apparatus may be sensitized so that the usual diaphragm condenser arrangement 38 responds only to the presence of the wanted gas in the sample chamber. In this condition, however, one of the radiation paths is transmitting more energy than another giving the apparatus a zero error. According to the invention this is eliminated by a third radiation path comprising cells 46, 50, containing an inert gas and provided with an additional trimmer 56. The energy pulses in this path are of constant amplitude and are fed into detector chamber 25 to " zeroize " the instrument. It is stated that chopper plate 40 may be so formed as to transmit energy in the first path alternately with that in the second and third enabling a single detector chamber to be used.

Title: Improvements in or relating to thermostats
IPC: G01K5/62
Filed: 1936-06-08
Abstract: 481,277. Thermal switches. PARMENTER, F., [Representative of PAYNE, M.], and BRITISH THERMOSTAT CO., Ltd. June 8, 1936, No. 16022. [Class 38 (v)] [Also in Group XIII] In a thermostat for regulating room temperatures, the body part 1 is attached to and spaced from a wall 3 by a tubular extension 2, and is closed by a cap 4 having openings 5, and an extension 6 covering an opening 2a in the extension 2. A bimetallic strip 9 is carried by a support 10 threaded at 11 into the body 1, and carries a contact 13 at its free end co-operating with a fixed contact 14. Terminals 7, 8 are provided in the part 2. For adjusting the bimetallic strip, a bushing 21 is threaded on the part 11, and, when rotated, acts on a rod 16 supported by a bracket 18 carried by the strip, thereby adjusting the temperature control point of the strip. An open ended tube 23 encloses the strip. The construction facilitates the free flow of air over the strip, and the spacing away from the wall ensures that the strip is not affected by convection currents of air near the wall. In a modification, Fig. 3 (not shown). an electric heater is placed in the casing above the strip, to induce an upward circulation of air.

Title: Improvements in or relating to artificial arms
IPC: A61F2/58
Filed: 1943-10-01
Abstract: 574,324. Artificial limbs. BLATCHFORD, W. A. Oct. 1, 1943, No. 16116. [Class 81 (ii)] In an artificial arm having an elbow joint 3 and an appendage 10 adapted to move the forearm member 7 and also to actuate a gripping or hand appliance 23 by mechanism similar to that described in Specification 559,494, means are provided whereby the appliance normally held in its open position by spring means 26 is maintained in its gripping position without the wearer having to keep a pull on the appendage. A coiled spring 27 is mounted on a sleeve 9 fitted to the flexion arc 8 and is secured at one end to the arm 6 of the forearm member 7 and at the other end to a ratchet member 28 freely mounted on the sleeve. On rotation of the sleeve in one direction the coils of the spring bind on the sleeve and hold the plunger 13 in a depressed position and the jaws 24 in their gripping position. To release the locking, a lever 29 coacting with the ratchet member 28 is operated by hand or by an appendage to disengage the spring from the sleeve. On raising the lever 29 to a higher position, a spring-controlled pawl 32 engages with a tooth 34, thus holding the locking means out of action until a still further movement of the lever releases the pawl and allows the member 28 to return to its original position. The gripping member 23 may be rotatable in, and detachable from, the forearm and may be yieldably or positively locked therein, for example by the means described in Specification 550,886. The Provisional Specification refers to an alternative form of locking device in which the flexion arc is formed with rack teeth, or connected with a member having rack teeth, adapted to be engaged by a pawl on a spring-controlled pivoted lever member.

Abstract: 1,080,698. Air-locks. UNITED STATES ATOMIC ENERGY COMMISSION. April 14, 1965 [April 29, 1964], No. 16127/65. Heading B7S. An air-look for an access door 7 in a side wall of a sealed chamber or compartment 5, comprises a flexible bag (2), Fig. 5 (not shown), having an opening at one end that can be closed by a so-called zip-fastener 18, a gas-inlet duct (9) and a gas-outlet duct (10), Fig. 3 (not shown), the bag being clamped at its periphery between a frame 3 and a flange 1 attached to said wall. Atmospheric air within the bag is replaced by a gas, or mixture of gases, similar to that filling the compartment, e.g. dry air or nitrogen, before the door 7 is opened when an object is to be transferred to the interior of the compartment. The air-look can also be used for the transfer of an object from the compartment to the exterior thereof, the gas within the bag being replaced by atmospheric air before the bag is opened. The rate of flow of gas into the bag from the duct 9 is controlled by a valve (11), and an orifice (12) within the duct, whilst the rate of flow of gas through the duct (10) is regulated by a valve (13), the valves being either manually or solenoid-operated. Alternatively, the valve (13) may be opened by gas pressure acting upon a spring-biased diaphragm (14), Fig. 4 (not shown). The bag may be made of rubber, neoprene or nylon, and may contain a pivotally-mounted platform 6 for supporting objects placed therein.

Title: Improvements in and relating to universal induction regulators
IPC: H01F29/08
Filed: 1932-06-14
Abstract: 400,714. Control of A.C. motors. SOUSEDIK, J., Vsetin, Czecho-Slovakia. June 14, 1932, No. 16854. [Class 38 (iii).] An induction regulator for supplying a variable voltage of fixed or adjustable phase to commutator motors for example comprises a pair of polyphase primary windings S1, S2 connected in parallel and arranged on stator cores to produce oppositely rotating fields therein and a pair of rotors on a common shaft and carrying polyphase secondary windings R3, R4 connected in series. The rotors are angularly adjusted simultaneously to produce voltage regulation from maximum positive to maximum negative without phase shift. Phase shift may be introduced, however, to compensate for the wattless component of the motors to be controlled by unequal angular displacement of the two rotors or by angular displacement of one of the stators. Auxiliary brushes 6 co-operating with projections on the rotor slip rings are provided for short-circuiting the windings R3, R4 in the neutral position in which their voltages are opposed. In one form in which the rotors are simultaneously shifted, a fixed amount of phase displacement is introduced by connecting in series with the two secondary windings a winding V1, Fig. 5, located at a predetermined angular position on one of the stators. In a further modification, Fig. 6, a similar result is obtained by connecting in series with the main rotor windings R3, R4 an auxiliary stator winding S5 energized by an auxiliary rotor winding R5 fed by and rotating with the main rotor windings. The amount of phase displacement introduced by the winding S5 may be varied by angularly adjusting the stator on which it is carried.
