Title: Hypodermic injection device and ampoule
IPC: A61M5/20
Filed: 1949-03-09
Abstract: 658,535. Hypodermic syringes. BECTON DICKINSON & CO. March 9,1949, No. 6473. Convention date, March 11, 1948. [Class 81(ii)] In a needleless hypodermic injection device means are provided for cleaning or clearing the orifice through which the medicament is discharged. As shown, compressed fluid from the flask 11 is, after completion of the injection, used to clean the cannula 23 by passing down the bore 27 in the piston-unit 24. The flask 11 is enclosed within the cap 12 the screwtightening of which causes the cannula 14 to penetrate the neck of the flask thus releasing the fluid, the flow of which is controlled by valve mechanism as described in Specification 662,943. The fluid actuates the piston-unit 24 which causes the movable plug 20 in the ampoule 19 to move downwardly ejecting the medicament through the cannula 23. Ribs 33, formed on the skirt 25 of the piston-unit are aligned with similar ribs 32 formed on the inner face of the body 10 and when the ends of the ribs abut as in Fig. 1 the piston is rendered inoperative. On rotation of the spring-loaded collar 30 the ribs 33 align with the spaces between the ribs 32 and the parts may then be telescoped. On this further movement of the piston 24 the plug 20 is pierced by the cannula 23 thus allowing the compressed fluid to flow through the bore 27 to the nozzle. Rotation of the piston-unit is effected by the engagement of the pin 29 on the collar 30 with a groove 28 on the plunger part 26 of the piston. On removal of the cap 22 for replacement of the ampoule the pistonunit is moved into the cylinder 18 where the spring 31 causes re-alignment of the ribs 32, 33. In a modification, Fig. 7, rotation of the collar 30 after iniection of the medicament allows the compressed fluid to reach the nozzle via a channel 42, the space between the ampoule body and the plunger 34 and grooves 35 formed on the outer-end of the plunger.

Title: Improvements in or relating to regulating devices
IPC: F23N5/00
Filed: 1931-03-02
Abstract: 374,867. Electrically-actuated valves. AKTIEBOLAGET CARBA, 2, Norrmalmstorg, Stockholm. March 2, 1931, No. 6478. Convention date, March 1, 1930. [Class 135.] In a regulating device, adapted more particularly for regulating combustion in furnaces and applicable also for controlling the charging of gas producers, the members to be regulated are actuated, directly or indirectly, by pressure differences continuously maintained by virtue of the diffusion of gas into a diffusion chamber and absorption of the diffused gas. As shown, applied to the regulation of furnace combustion, the diffusion and absorption apparatus 1 acts a carbon dioxide meter, the carbon dioxide in the flue gases which are passed through the right-hand compartment diffusing through the porous member 2 and being absorbed by a medium 3 in the left-hand compartment. The pressure difference thus set up causes movement of a flexible diaphragm 4 carrying a contact 6 adapted, by engagement, with adjustable contacts 8, to complete electric circuits which include relays 7 or the like for actuating members controlling the supply of air and/or fuel to the furnace. In the application of the invention to the charging of gas producers, pressure differences set up by diffusion from the gas generated and absorption of the diffused gas are utilized for regulating the supply of fuel to the producer or for varying the composition of the charge. According to the Specification as open to inspection under Sect. 91 (3) (a) the device may, instead of actuating the regulating members themselves, be arranged to operate signal devices which indicate that regulation is neces sary. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for the control of an aircraft's speed
Inventor: GORHAM JOHN ANTHONY DAVID
IPC: G05D1/06
Filed: 1959-02-25
Abstract: 882,334. Automatic speed control systems for aircraft. SMITH & SONS (ENGLAND) Ltd., S. Feb. 24, 1960 [Feb. 25, 1959], No. 6488/59. Class 38 (4). In an aircraft automatic speed control system, signals dependent on rate of pitch of the aircraft are supplied through a filter having special characteristics and combined with signals dependent on aircraft speed error to control propulsive thrust of the aircraft. As applied to the control of a four-engined aircraft, a computer 42, Fig. 1, associated with a pressure head 43, produces two identical signals proportional to deviation of airspeed from a value determined by the setting of a knob 16. One of these signals controls the outboard engines and the other the inboard engines. The outboard engine control signal on line 3 is applied to a summator 4 together with a signal derived from a rate of pitch gyro 14 through a filter 15 which is provided with rectifiers and decay networks to eliminate transient effects such as would be caused by turbulence. The resultant signal from summator 4 is applied through amplifiers 8, 8a to control servomotors 23, 23a adjusting outboard engine throttles 28, 28a to maintain constant airspeed. Each servomotor control system is provided with position and rate feedback. The inboard engine throttles 28b, 28c are controlled in a similar manner by the second airspeed error signal on line 3a and a signal derived from a second rate gyro 14a. The two airspeed error signals are also respectively applied to electro-mechanical integrators 12, 12a producing rotary outputs which are combined in a differential gear 19 so that the addition is effective to operate generators 22- 22c applying signals proportional to the integral of airspeed error to the servomotor amplifiers. A differential output from gear 19 operates a rate generator 29 which supplies a signal to a warning and cut-out device 30 in the event of inequality of the two inputs to the differential gear 19 under fault conditions. The signals from the two summators 4, 4a are compared by a unit 7 which also supplies a signal to warning device 30 under fault conditons. The signals from the pitch rate gyros may be added to the inputs of the integrators. Operation of ganged switches 6, 9, 6a, 9a to the other position shown disables automatic airspeed control and permits signal sources 44, 44a to progressively close the throttles through the integrators during landing. In a modification for controlling a two-engined aircraft A.C. control signals are employed and a single integrator of combined airspeed error signals and pitch rate signals applies its outputs to the stators of signal generators providing positional feedsback in the throttle servo-systems. Warning of faulty operation in this case arises from a difference between signal generators adjusted by the two servomotors.

The ring 18 is formed with a crossbar 21 carrying a radial knife as described in Specification 546,839. A cover 23 hinged to a pin 24 is normally urged by a spring 25 into contact with a packing ring 26 in the outer face of the ring 18 and secured by a headed frangible pin 33. This pin has a reduced part 35 and is passed through a hole in a pin between lugs 31 on the cover and screwed into a threaded hole in the ring 18 by inserting a tommy into a hole 36 just above the threaded part. Parts of the cover on either side of the cross bar are depressed so that the inner surface is adjacent the outer surface of the diaphragm and so prevents distortion of the diaphragm by normal variations of pressure. Modifications are described in which the cover is secured by a spring-loaded or pressure released catch.
