Abstract: 616,737. Thermal switches. TRIGGS, W. W. (Landers, Frary, & Clark). Sept. 10, 1946. No. 27209. [Class 38 (v)] The operating temperature of a thermostatically-controlled electric iron is varied by sliding a control knob 47. The movable contact 17 is carried on a lever 18 which is pivoted at 19 to a U-section arm 20 pivoted at 21, and actuated by a bimetal bar 15 engaging a lug 22 on the lever 18. A spring 26 attached to the lever 18 and the end of a bracket 27, riveted at 25 to a plate 24 extending into an opening 28 in the shell 11, holds the recessed top of the arm 20 in engagement with a screw 23 in the plate 24. The distance between the lug 22 and the bimetal bar 15 is altered by rotation of a stem 30 in the bracket 27 and having a tongue 31 engaging a slot in the screw 23. A toothed head 32 of the stem 30 mates with teeth in a hole in a U-shaped yoke 33 having openings 54 slidably receiving a bar 53, pivoted at 52 to an arm 50 in a slide 43, The arm 50 passes through a slot 51 in the body part 12 on which prongs 4!) of the slide 43 move, and the slide has rollers 42 engaging a groove 41 beneath a bridge 40 integral with the handle 13. The control knob 47 is secured to extensions 46 of the slide to cause rotation of the yoke 33 by the bar 53 and hence rotation of the screw 23, whereby the operating temperature is varied. In a modification, Fig. 4, the bridge 40<1> is T-shaped and carries a temperature scale with which a pointer 63 on a slide 43<1> co-operates. The slide moves on a side flange 61 of the bridge and pivotally supports at 52<1> the yoke operating bar 531. A leaf spring 70 on the yoke 33 holds it in engagement with the toothed head 32.

Patent GB-739133-A (GB)
Title: Improvements in and relating to hydraulic shock-absorbers
IPC: F16F9/512
Filed: 1953-10-06
Abstract: 739,133. Hydraulic shock-absorbers. BENARD, L. Oct. 6, 1953 [Oct. 13, 1952; Sept. 15, 1953], No. 27444/53. Class 108 (3). The invention relates to hydraulic shock - absorbers of the type comprising a piston 44 sliding in a cylinder 1, and having an annular flow-restriction passage 52, formed between a portion of the piston, and a member 53 slidably mounted between two opposing springs 58, 59. According to the invention, the annular passage 52 is formed by an internal flange 48 on the body of the piston 44, and a flange 51 on the member 53, washers 55, 56 being disposed between the flanges 48, 51, and the springs 58, 59, and having apertures 57 in front of the passage 52. The piston comprises an annular member 44 held between members 41 and 42 which are secured rigidly to the piston-rod 8. The flange 51 is normally aligned with the flange 48 by the action of the washers 55, 56 and springs 58 and 59. The passage 52 normally provides damping, but on excessive load, one or other spring is deflected, and the flange 51 moves axially to increase the passage area. The spring 59 is stronger than the spring 58. The flange 51 may be of nylon, or of a material known by the Registered Trade Mark " Zamac." The piston member 44 is of a material having a lower coefficient of expansion such as sintered iron. This is to avoid a reduction in damping due to temperature change. Both of the peripheral edges of the flange 48 are chamfered, but only the upper edge of the flange 51 is chamfered. Damping is also provided by a 1 mm. clearance between the piston and the wall of the cylinder 1. An annular recess 64 in the piston is to prevent emulsification of the working liquid. The apertures 57 in the washers 55, 56 may also contribute to the damping. Flow into a reserve space 20 is controlled by a piston valve 34. Flow back into the cylinder from the space 20 occurs through a valve 28, and emulsification is prevented by baffles 23, 29.

Title: Neutron detector unit and system
IPC: G01T3/00
Filed: 1973-06-08
Abstract: 1418937 Detecting neutrons; monitoring nuclear reactors GENERAL ELECTRIC CO 8 June 1973 [8 June 1972] 27466/73 Heading G6P A neutron detector (Fig. 2) comprises a sealed chamber 21 containing an ionizable gas e.g. argon, first, second and third electrodes 16, 17, 18, dielectric 19 (such as aluminium oxide) filling the space between the first and second electrodes and neutron sensitive material 22, e.g. uranium-235, between the second and third electrodes. Various electrode materials, and others, are specified. The construction affords a fission-chamber portion 31 required to be powered by a source 24, and a self-powered portion 30 in which one of the electrodes (e.g. electrode 16) acts as collector and the other as emitter. Two practical constructions are described. In one (Fig. 5, not shown) the first electrode (101) is in the form of a stainless steel tubular sheath surrounding the second electrode (103), the third electrode (107) being the central electrode surrounded by the ionizable gas. Electrical connections to the electrodes are made via a tri-axial cable (111). In the second (Fig. 6, not shown), the third electrode (201) forms the tubular sheath, the first electrode (207) being centrally disposed. The detector is used to monitor neutron flux in a nuclear reactor core. In one application (Fig. 3) periodic adjustment of the calibration of the fission-chamber portions is effected using a computer 33 which, via an actuator 36, operates a stepping switch 34 to connect in selected detectors. The computer provides to a gain control device 32 a signal proportional to the current sensitivity (at time t) of the fission-chamber portions, and the device 32 sets the gain of amplifier 128 so that the output of the latter is calibrated in accordance with that sensitivity (which decreases due to burn-up of the neutron sensitive material). In a second application (Fig. 4) each detector is individually associated with its own computing and gain control system to provide continuous calibration adjustment of the fission chamber portion by adjusting the gain of output amplifier 128.

Abstract: 444,962. Gas-masks. DAWSON, W., 50, St. George's Road, Golders Green, London. Sept. 26, 1934, Nos. 27476 /34 and 20286 /35. [Class 81 (ii)] A gas-mask formed of sheet material is provided with an exhaling valve comprising a tube closed by a plug held to a conical seating in the end of the tube by resilient means. As shown in Fig. 2, the tube 8 is secured to the mask 1 by a screw ring 10 and washer 12 co-operating with a flange 11 on the tube. Screwed into the end of the tube is a fitting 13 having a conical valve seating 14 and circumferential air outlets 21. The valve 15 has guide lugs 18 and a stem 19 slidable in a cylindrical guide 17 on screw cap 16. A spring 20 surrounds the stem 19 and guide 17. The tube 8 is bent at right angles to permit downward closing of the valve. In a modification a straight tube is formed integrally with an apertured valve casing having a screw - on end cap and enclosing a conical valve spring. The valve engages a conical seating in the end of the tube and is guided by a stem fitting the tube and having longitudinal flutings. The tube is extended within the mask to form an integral or detachable fish-tail or other mouthpiece. The mask 1, Fig. 1, is of sheet rubber or other material and is provided with elastic head bands 2 and a chin strap 4 secured to the mask at each end and along one side. Eyepieces 6 are secured in the mask by rubber frames 7, and sealing strips 5, of rubber tube or fur, are provided on the face engaging edges. The lower end of the mask forms a trunk 3 to receive a filter or other purifying means. The Provisional Specifications describe an exhaling valve comprising a conical plug held to a seating in an exhaling tube by elastic bands secured to the mask and lying in slots in the valve, an additional valve being provided comprising a patch covering the valve and partly secured to the mask at its edges, air escaping past the unsecured portions ; the mask is described as constructed or constructable of transparent material. One of the Provisional Specifications refers to a mask made from a section of motor-car inner tube, shaped at the top to fit the face and furnished with eye pieces, the lower part forming a trunk to receive a filter canister; the facecontacting edges may be treated with gum and the trunk sealed at its lower end, the filter being inserted from above.

Title: Improvements in or relating to locks
IPC: E05C1/06
Filed: 1947-10-14
Abstract: 631,636. Locks. PERL, A. H. F. Oct. 14, 1947, No. 27486. [Class 44] In a lock, a rotatable operating member is connected to a sliding latch or bolt, the movement of the operating member is limited by stop means comprising a stop member which normally occupies a position in the path of an abutment carried by the operating member so as to define the position of the operating member when the bolt is in shot position, but which is movable to allow the operating member to be turned beyond its normal end position to carry the abutment past the stop member into a position where the abutment (or another abutment) on the operating member is engageable by the stop member so as to lock the operating member against return movement ; the connection between the bolt and the operating member is such that the bolt is locked when the operating member is locked. To release the operating, member, the stop member is disengaged to allow the operating member to be turned back to normal operating arc. The additional movement of the operating member and locking of the latter and of the bolt follow positively and immediately from operation of the stop member, so that it is impossible to lock the mechanism and then shut the door. In a simple construction shown diagrammatically in Fig. 1, the bolt 2 is connected by link 7 and lever 6 to a spindle 5 carrying an operating member 10 and handle 4. An abutment 11 on member 10 co-operates with a pivoted stop member 12 which can be lifted, to allow member 10 to rotate counter-clockwise, and then returned so that abutment 11 contacts its other side preventing clockwise movement of member 10 and consequent withdrawal of bolt 2. The operating member may be spring urged towards shot position and member 12 to engagement with the operating member. In the form shown in Fig. 6, the mechanism is incorporated in a rose fitting. The operating member 10 is mounted on the square spindle 5a and has a locking abutment 11 co-operating with a pivoted stop member 12 manually operable by an external lever 16. Both operating and stop members are biased by a coil spring 17. In the locked position as shown, the stop member 12 has been lifted to allow abutment 11 to move counter-clockwise and then dropped behind the abutment. In another modification, separate loading springs are used for operating and stop members, and the stop member is of substantially triangular form and operates on a dead centre spring arrangement. The construction shown in Fig. 9 embodies a stop member 12 with two ears 27, 28, one of which engages one side of the abutment 11a in the normal shot position, while the other engages the other side of the abutment in the locked position. This construction is symmetrical so as to be applicable to right or left hand locks, the spring controlling the operating member being made reversible. In any of the forms, the connection between the operating member and the latch or bolt may include a lost motion linkage, for example as shown in Fig. 13.
