Title: Improvements in hypodermic injection apparatus
Inventor: SADD JOHN AMBROSE
IPC: A61M5/30
Filed: 1956-03-10
Abstract: 822,814. Surgical injection appliances. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 6, 1957 [March 10, 1956], No. 7575/56. Class 81 (2). A needleless injection device for hypodermic use, having a plunger for making the injection and impact producing means for striking the plunger, has a pivoted platform on which a patient stands with a cable extending between the platform and the device so arranged that as the platform moves to its unloaded position the impact producing means is cocked for a subsequent injection. The injection appliance comprises a cylinder 1, Fig. 1, with a piston grip handle 2 connected through a flexible tube 41 to a container 43 of vaccine, pressurized by a pump 44, and also connected through a flexible cable 8 to a pivoted platform 12 on which the patient stands. When a patient steps off the platform the spring 17 expands, so drawing back the cable 8 and, by means of a lug 6, see also Fig. 3, compressing a spring 24. The action of drawing back the trigger 45, Fig. 1, is to close a valve in the vaccine supply and to withdraw a detent 35 from the striker 23, Fig. 3, which consequently strikes the head of the plunger 28 and drives the charge of vaccine from the cylinder 42, past valve 29 and out of the orifice 33. As each patient steps off the platform the striking mechanism is automatically cocked for the next operation by the expansion of the spring 17. In order to determine the dosage the starting position of the plunger 28 is set by a threaded rod 58, Fig. 3, screwed into the end-plate 20. Specification 766,431 is referred to.

Title: Improved method of and apparatus for treating colloidal dispersions
IPC: C08C1/14
Filed: 1944-04-24
Abstract: 641,780. Coagulating rubbers. FIRESTONE TIRE & RUBBER CO. April 24, 1944, No. 7631. Convention date, May 10, 1943. [Class 70] [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 25, 1944.] Rubber and rubber-like materials such as copolymers of butadiene with styrene or acrylonitrile dispersed in an aqueous liquid are coagulated by continuously admixing with the dispersion a liquid coagulant to form a pool of aqueous mixture from which the coagulum particles are continuously elevated. The coagulant may be methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, acetone or aqueous solutions of acids, alkalis or metallic salts such as aluminium sulphate. The method is preferably carried out in an elongated housing 13 inclined at an angle of about 15 degrees, closed at its lower end and open at its upper end, and provided with inlet means 32 for introducing the rubber dispersion and inlet means 31 for the liquid coagulant. A feed screw 16 rotating in the housing elevates the coagulum and spent liquid towards the upper end of the housing and at the same time kneading and agglomerating the coagulum against the housing wall. The overflow 34 from the housing is so arranged that a pool of liquid accumulates in the lower end of the housing. The coagulum then passes on to an inclined shoot 35 fitted with a pervious screen 36 which separates the solid material which passes to power driven squeeze rolls 40. The coagulum then passes on endless conveyer 42 to dryer 43. In a modification (Figs. 3, 4 and 5, not shown), the wet coagulum is forced through a foraminated trough in which further quantities of liquid are removed. In a further modification the coagulum is passed through a pellitizer such as that disclosed in Specification 594,457, [Group IV]. The Specification as open to inspection under Sect. 91 comprises also the coagulation of any colloidal dispersion according to the method of the invention, utilizing any liquid, solid or gaseous coagulant. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to microwave wattmeters
IPC: G01R21/00
Filed: 1953-03-19
Abstract: 740,915. Power measuring. CULLEN, A. L., and WAYNE KER LABORATORIES, Ltd. March 19, 1954 [March 19, 1953], No. 7671/53. Class 37. A torque-operated microwave wave-guide watt-meter which provides measurements independent of the standing wave ratio comprises a pair of co-planar vanes 14, 15 rigidly connected as by supporting-rod 16 and suspended centre: to centre a quarter guide length apart by a torsion fibre 19 in a vertical section of waveguide formed by right-angled bends 12, 13. If there is any standing wave in the wave-guide the individual torques on the two vanes 14, 15 will differ but the total torque of the two combined is substantially independent of the standing wave ratio. In one method of use the vanes are set at 45 degrees to the axis of the horizontal input and output rectangular section guides 10, 11. The power is then switched on and the torsion head 20 turned with reference to scale 21 until the spot of light reflected from mirror 22 is brought back to its original position. In an alternative method the torsion head 20 is twisted back until the vanes 14, 15 are in their original position and the power flow is then switched off so that the deflection of the light spot indicates power flow. The reflections of incident waves at each of the bends 12, 13 is almost exactly cancelled by the reflections at the adjacent vanes 14, 15 when the vanes make an angle of 45 degrees to the electric field. However, if desired, additional compensation may be provided by inductive or capacitive diaphragms or by matching screws at one or both bends 12, 13. The vanes 14, 15 may be metal foil or wire structures and the supporting rod 16 is preferably of insulating material. The rod 16 is bent into a hook 23 which is immersed in a fluid to form a dashpot 24. The Specification acknowledges that it is a known art to use a single metal vane assembly and in this connection refers to monographs 24 and 42 of the Institution of Electrical Engineers.

Abstract: 492,527. Feeding webs. ROLLINSON, E. W. (Trans-Lux Daylight Picture Screen Corporation) March 18, 1937, No. 7988. [Class 100 (i)] Apparatus for moving a tape or web from a printing-device through a projection field comprises roller means for feeding a tape toward the projection field, the roller means being positioned along the tape path between the projection field and the tape-feeding means of the printing-device, a motor for driving the roller means, means comprising switch contact mechanism for opening and closing the circuit of the motor in response to change in configuration of a tape loop disposed adjacent the entrance to the projection field, a rewind reel for the tape operated by the motor, and means forming a slipping connection for rotating the reel to prevent the tape being torn during rewinding. The ticker mechanism P is of the type which prints one or two lines of characters on a tape T, and feed rolls 1, 1a feed the tape to the type-wheel 2. The external feed means for the tape is arranged between the ticker and a projection apparatus A, and comprises two wheels 22, 23, the former being secured to a shaft 24 driven by chain and sprocket means from a motor 33. The feed wheels 22, 23 damp down any oscillations in the tape before it passes over the apparatus A. A pivoted feeler arm 39 controls the motor. The motor circuit is broken when the loop of the tape is straightened out due to the stoppage of the ticker, since the arm 39 carries a contact 40 which separates from a fixed contact 42 to cut off the power supply to the motor. Where two lines of characters are printed on the tape the end 39a of the arm 39 is a single member bearing centrally on the tape, and the wheel 23 is a single disc, but where a single central line of characters is printed, there are two members on the arm 39 and two discs in the wheel 23. A re-wind device for the tape is provided comprising a pulley 38 driven by a spring belt from the shaft 24, and the tape is guided across the apparatus A by a guide or roll 45<1>. The tape may be guided by side plates and flanges in the projection field, or the condensing lens of the projection field may be grooved to form a guide for the tape. Reference has been directed by the Comptroller to Specifications 349,194, 349,195, and 393,540.
