Abstract: 812,183. Ionization counters. ATOMIC ENERGY OF CANADA Ltd. July 24, 1956 [Aug. 1, 1955], No. 22889/56. Class 39(1). In a Geiger-Nuller counter tube comprising a tubular cathode and an anode-extending centrally of the cathode, the spacing between the outer surface of the anode and the inner surface of the cathode has substantial variations along the length of the anode, and all parts of said cathode are inter-connected for simultaneous operation. The tube is preferably halogen quenched. In one embodiment, Fig. 2, the tube comprises a tubular cathode 10 fitted with an end-window 11 and a seal 12 supporting the anode 13. The inner surface of the cathode comprises a conical portion 15 and a cylindrical portion 16. Alternatively the cylindrical portion may be omitted or the surface may comprise two cylindrical portions of different diameters. The outer surface of the cathode 10 may be shaped similarly to the inner surface to produce a uniform wall thickness, and the cathode may then be formed by pressing from sheet metal. In Fig. 5 the inner surface 19 of the cathode 10 is cylindrical and the anode 13 comprises a conical portion 20 and a cylindrical portion. Alternatively the anode may be wholly conical or may comprise two cylindrical portions of different diameters. In Fig. 7 a conical section 23 and a cylindrical section 24 of the cathode are separated by an insulator 25 to allow trimmer resistors to be included in the circuits to the separate cathode sections. All the constructions enable beta and gamma radiation of different intensity ranges to be measured with a single tube. The end-window 11 may be omitted when measuring only gamma radiation or may be retained and used for calibrating the tube with a built-in beta source which is shielded by a shutter during gamma measurement.

Filed: 1967-05-17
Abstract: 1,223,840. Rotary wire stitching machines. STRACHAN & HENSHAW Ltd. 15 May, 1968 [17 May, 1967], No. 22999/67. Heading B4C. [Also in Division B8] A rotary wire stitching machine comprises at least one stitching head 12 carried by a cylindrical drum 10 or mounted on an arm rotatable about an axis, the head including a forming member 13 part of which 22 is positionable radially outwardly of a stitch-forming wire blank carried by the head so as to trap part of the blank against radially outward movement during shaping of the blank to U-shape by ears 18 (Fig. 3) moving outwardly and substantially radially of the drum relative to the forming member and an anvil 21. The wire blank is formed by feeding wire from a nozzle (36) (Fig. 1, not shown) transversely of a channel 29 and by motion of a pusher arm 28<SP>1</SP> past the nozzle to cut the wire. Pusher arms 28, 28<SP>1</SP> on a delivery cylinder 27 advance the blank to a position in which a head removes the blank from the channel by engagement of steps 43 on the ears, with the blank which is positioned between but not contacted by the part 22 of the forming member and the anvil. The forming member 13 and the anvil are then moved so as to trap the blank during shaping of the staple by movement of the ears 18. After the staple has been shaped the head moves past overbending blocks 26, which force the legs of the staple inwardly, to a carrier roll 23 which carries the signature of a book. The ears are retracted and the forming member is removed as the staple enters the signature at a stitching station. The staple is then forced against a clinching block 25 by the anvil to form a stitch. The anvil and ears have slots 41, 42 therein to locate the staple. The carrier roll may be used as a collecting cylinder on which more than one batch of sheets is collected at a collecting station before stitching occurs. The delivery cylinder may have two pusher stations (Fig. 7, not shown) and the drum 10 and the collecting cylinder may have three stitching heads and stitching stations respectively. For collecting two batches to form one signature one of the two pusher stations is rendered inoperative. The delivery cylinder may be replaced by a feed belt or conveyer.

Title: Improvements in apparatus for mixing gases
Inventor: EDMONDSON WILLIAM
IPC: B01F5/00
Filed: 1958-07-19
Abstract: 867,597. Mixing gases in flow. ANãSTHETIC EQUIPMENT Ltd. July 14, 1959 [July 19, 1958], No. 23260/58. Class 86 [Also in Group VI] In an apparatus for supplying a mixture of two gases, particularly anaesthetic gases, in predetermined proportions, the pressure of the constituent gases is first equalized. Nitrous oxide and oxygen are respectively admitted through inlet ports 10, 11 and inlet valves 13, 23 into chambers 14, 24 having bellows portions 15, 25. The pressure in the chambers is equalized by levers 18, 28 having projections 19, 29 bearing on the extensible portions of the chambers. The outer ends of the levers are connected by the adjustable tension spring 32 and their inner ends have members 20, 30 bearing on the inlet valves 13, 23 to actuate them in a closing direction as pressure rises in the corresponding gas chamber. The pressure equalized gases pass from chambers 14, 24 to the mixing valve 12. Nitrous oxide from duct 40 enters the annular chamber 50 which communicates with upper cavity 47 in the hollow valve spindle 44; oxygen enters the lower cavity 48 in spindle 44 via duct 41 and chamber 51. The spindle has an arcuate oxygen port 65 and two arcuate nitrous oxide ports 67 co-operating with ports 66, 68 respectively in the valve sleeve 45, whereby the gases are admitted to the mixing chamber 42. The angular disposition of the arcuate ports is such that any desired proportion of nitrous oxide to oxygen may be pre-selected by manually rotating the hollow spindle 44 by means of the knob 52, see Figs. 4-7 (not shown). One wall of the mixing chamber 42 is formed as a flexible diaphragm 60 which controls the rate of flow of the mixed gases by actuating the bell crank 59 to displace the valve sleeve 45 axially in such a direction that when the pressure of the mixed gas in the mixing chamber 42 is at a maximum or is excessive, the gas ports in spindle 44 and sleeve 45 are axially out of register. The mixing chamber 42 communicates with a delivery chamber 72 by means of a valve 70 upon which the gas pressure in the mixing chamber acts in a closing direction. The wall 73 of delivery chamber 72 is flexible and acts upon valve 70 to open it when flexed as the patient inspires. Alternatively any desired gas pressure may be provided in the delivery chamber (and hence in the breathing tube) by manually rotating the knob 80 which acts through cam 82, lever 74, pressure pad 75 and wall 73 to hold valve 70 open.
