Abstract: 1311405 Measuring temperature electrically SIEMENS A G 18 Aug 1971 [25 Aug 1970] 38846/71 Heading G1N [Also in Division H1] Temperature measuring apparatus comprises a resistance thermometer 2 of which the resistor 2<SP>1</SP> is disposed with thermocouple junctions 3<SP>1</SP>, 4<SP>1</SP> in a probe unit 1 for immersion in the medium of which the temperature is required, thermocouple 3 being relatively slow-acting compared with thermocouple 4 which is relatively quick-acting compared with the resistance thermometer, the thermocouples being connected in series - opposition to produce at circuit 5 an output signal corresponding to the difference # TE  of the indications from the two thermocouples, which signal is combined at 7 with that from the resistance thermometer and the resultant is indicated at 8. Thus the difference # TE  goes to zero as the output from the slow-acting thermocouple rises, while the resistance thermometer assumes the temperature of the medium, sothat in the steady state the error in the resultant signal is due only to the resistance thermometer and is small whilst in the transient state the high speed of response of the thermocouple 4 determines the resultant. The probe has a tube 11 filled with an electrically insulating mass of high thermal conductivity and tapered to end 13 inside which the junction 4<SP>1</SP> is disposed. Disposed above the end and adjacent each other in the tube are the resistor 2<SP>1</SP> and junction 3<SP>1</SP>.

[Also in Division G6] A safety device for a nuclear reactor comprises an absorbent rod movable axially in a horizontal channel, means for propelling the rod in the channel to bring it to a position leading to shut-down of the reactor, a stem coaxial with the rod and along which the rod is slidable, the stem having at its forward end an end portion for braking and stopping the rod at the end of its stroke, an annular punch slidable along the stem between a position intermediate the ends of the stem and a position adjacent the braking end portion, and a series of rings attached to the rod and deformable by the punch as the rod approaches the end of its stroke. In the embodiment described, the rod 2 is propelled by means of a detachable propeller 12 (shown in Fig. 1) situated in a fixed ferrule 13 inside a tube 4 which forms an extension of a horizontal channel in the reactor moderator. The propeller 12 comprises a pressurized-gas chamber 15 closed by a diaphragm 16. By means of a firing pin 17, operated by a pyrotechnic device, the diaphragm 16 can be caused to rupture so that the gas escapes under pressure along the ferrule 13 to the rod 2. An extension 18 on the propeller unit is attached by means of a stud and slot coupling 23 to a gripping socket 20 on the rear end of a stem 6 upon which the rod 2 slides. Braking of the rod 2 is effected by the deformation of rings 10 (Fig. 4) provided on the interior of the rear end of the rod 2. The internal diameter of these rings is less than that of the rod. They are deformed by an annular punch 11 which, before operation, is held at the front end of the rod 2. The punch 11 is slidable on the stem 6 and when the rod 2 is propelled into the reactor core, the punch 11 comes to bear on the end portion 8 of the stem 6 and then slides inside the rod 2 as far as the braking rings 10. The deformation of these rings absorbs the kinetic energy of the rod.

Abstract: 879,427. Hypodermic syringes. WALKER, G. W., ZIHERL, F., and ZIHERL, L. A. Dec. 31, 1957, No. 40441/57. Class 81 (2). A surgical injector comprises a body with a medicament chamber 21 at one end and a movable ejector 38 for discharging medicament therefrom, the ejector being retracted by fluid pressure and the chamber being recharged with medicament from a reservoir 49 which communicates with the chamber through the body and which extends externally of the body. A stainless-steel medicament chamber 21, having a small discharge aperture 27 is secured in a holder 20 attached to the body 11, by an apertured cap 22 which carries a resilient skin contact member 24. The forward end 41 of a hollow plunger 38 is moved into the chamber 21 to discharge medicament. A conventional hypodermic syringe 49 is secured to the rear end of the plunger 38 within the body 11. The chamber 21 is charged with medicament from the syringe 49 by operating the syringe plunger 52, a non-return ball check valve 43 in the hollow plunger 38 preventing back flow of medicament. A piston 14 slidable within bores 12, 13 in the body 11 is secured around the plunger 38, an accumulator spring 15 being disposed around the rear end of the plunger 38 between the rear face of the piston 14 and a sleeve 32 which is axially adjustable by a knob 33. Fluid is pumped from a reservoir 54 by a piston 61 reciprocated by a lever 64 into the bore 13 of the body 11, the fluid forcing the piston 14 and the plunger 38 rearwardly to compress the spring 15, ball check valves preventing back flow of fluid. The spring 15 may be compressed additionally by rotating knob 33 to displace the sleeve 32 forwardly if the plunger 38 is retracted only partially for injection of a volume of medicament which is less than the full capacity of the chamber 21. On pressing a trigger on the outside of the instrument, a valve stem 78 unseats a ball valve to allow fluid to flow from the bore 13 to the reservoir 54 so that the spring 15 is released and the plunger 38 forces medicament from the chamber 21 to an injection. The point of registry of indicia 50 on the syringe 49 with the knob 33 when the sleeve 32 is retracted gives the effective capacity of the chamber 21. Reference has been directed by the Comptroller to Specifications 798,826 and 798,827.
