Abstract: 1,160,902. Humidifying gases for respiration. CHEMETRON CORP. 10 Oct., 1966 [22 Oct., 1965], No. 45221/66. Heading AST. [Also in Division E2] A nebulizer apparatus (by means of which gas, for example oxygen, air or mixtures thereof, may be mixed with, for example, water vapour and the mixture may be administered to a patient, and especially to a face mask worm by the patient, is used in association with a container 13 adapted to contain a liquid L to be aspirated, the container having an outwardly-extending flange. The nebulizer apparatus comprises a body section 11 carrying a nebulizing assembly 20, a collar 12 adapted to engage the underside of the flange of the container 13. and means for clamping the container flange between the body section and the collar, the clamping means including at least two clamps 18, 19 spaced round the body section, each clamp comprising a first part secured to the body section and a second part secured to the collar. In Fig. 2, a rigid conduit 22 is adapted to be connected to a source of supply gas such as oxygen or air or mixtures thereof Liquid L, aspirated through tube 21, is discharged as a fine mist from nebulizing assembly 20 and mixes with the gas. The nebulized mixture of gas and liquid in the chamber C passes through an outlet conduit 23. A combined pressure relief valve and whistle 36 relives any excess pressure which may exist in the chamber C. The toggle clamps 18, 19 (see Division E2) can be released from the clamping position for removal of the container 13.

Title: Improvements in or relating to methods for use in the manufacture of lithographic printing master sheets
IPC: B41N3/03
Filed: 1961-12-20
Abstract: 927,783. Electrolytic manufacture of lithographic printing master sheets. W. RITZERFELD, and G. RITZERFELD. Dec. 20, 1961 [Jan. 2, 1961], No. 45630/61. Class 41. Lithographic printing master sheets are manufactured by passing two metal foil webs simultaneously through a common electrolytic bath. Each web 2 drawn from supply rolls 1 by transporting rollers 11 and 12 is conveyed to the bath 18 over at least one current conducting guide roller 4 which electrically contacts the webs, the guide roller for one web being connected to one pole of an electric supply 19 and the guide roller for the other web being connected to the other pole of the electric supply 19-the electric supply being the secondary of a transformerthe webs 2 being guided in the bath 18 in such a manner that for at least part of their passage therethrough they are substantially parallel to each other, whereby electrolytic roughening of one face of each web is effected, the other faces of the webs being subjected to an electrolytic action by electrodes 26, 27 arranged in the bath or in further electrolytic baths arranged separate from the first said bath, whereby electrolytic roughening of the said other faces is effected in the same working process as the roughening of the said one faces. The electrodes 26, 27 may be connected to an electric supply controllable independently of the first said electric supply. Preferably the electric supply 19 or each electric supply is an alternating current electric supply. Advantageously the electrodes 26, 27 are arranged in the said common bath 18 and are supplied with current as shown in such a manner that at any instant the polarity of an electrode is opposite to that of the web with which the electrode is intended to electrolytically cooperate. The webs 2 are soft-rolled aluminium foils of thickness between 0.04-0.09 mm., preferably of about 0.06 mm. thickness. The electrodes 26, 27 may be of carbon but carbon electrodes produce gaseous chlorine from hydrochloric acid electrolyte 18 and metal electrodes, preferably iron, are preferred. Electric current flows between the two webs 2 during their transit through the bath 18 and at the same time electric current flows between the electrodes 26 and 27 and the webs 2. Due to the dispositions of the webs 2 and the electrodes 26 and 27, the current flow between the webs 2 has the effect of causing an electrolytic roughening of the faces of the webs which face each other between rollers 5 and 6; and the current flow between the electrodes 26, 27 and the adjacent webs 2 respectively has the effect of causing an electrolytic roughening of the other faces of the webs 2. On leaving the electrolytic bath 18 the webs 2 pass through subsequent treatment baths 20, 21 and an infra-red drying device 22 followed by a pair of straightening rollers 16, 17 and cutting device 23.

Title: Sample changer for the automatic measurement of radioactive  samples
IPC: G01T7/08
Filed: 1974-10-24
Abstract: 1466779 Sample changer for the measurement of radio-active samples GAMMA MUVEK 24 Oct 1974 [25 Oct 1973] 45992/74 Heading G1A A sample changer for the automatic measure-  ment of radio-active samples comprises magazine 25 moveable above radiation detector 7 with transverse hole 7', with which vertical holes for samples 24 can be aligned and which with is aligned sample lifting rod 6, moveable in hole 7'. Through reducing gear 2, motor 1 drives control shaft 3, stepping disc 17, profile disc 4 and cam 8, which controls, via pick-up lever 10, element 11 for screening hole 7' and has nests 12 for engaging locking lever 13, coupled to clutch 14 via arrester 16. Roller 18 engages Geneva gear 19, wedged to shaft 20, which has gear 21 engaging rack 22. Guide cleats 53 enter grooves 32 Fig. 3. Cleats 26 and 29 are connected by bell-crank lever 28 with pins 28', 28" rotating about axle 27. Arrester 16 lifting lever 15, as clutch 14 disengages, makes lever 28 descend to release the coupling between frames 23 and 30. Button switch 52 signals when channel 51 in framework 39 Fig. 5 contains a sample and button switch 49 signals when it is jammed. Loaded magazine 25 is placed on frame 23 so that pin 37 enters slot 38 and pushes pin 33 into hole 36 and maintains releasing plate 31 fixed relative to frame 23. On switching on, control unit 46 monitors and adjusts the starting position with rod 6 at the top extreme position, and with frames 23 and 30 released the first sample 24 is brought by hand over channel 51, while plate 31 is stationary with respect to frame 23. With the order to start, unit 46 starts motor 1. Profile disc 4 causes the lowering of sample 24 into hole 7' and element 11 closes channel 51. Sample arrival is signalled, by a button switch operated by a pin on cam 8, to unit 46, which stops motor 1 during measurement and then restarts it. Element 11 retreats and rod 6 lifts the sample. Geneva gear 19 rotates through 90 degrees and rack 22 connected to frame 23 is pushed on one division moving the next sample 24 over channel 51. The above cyclic process is repeated, with the direction of rotation of motor 1 constant, until the last sample in the row has been measured. Then cleat 26, via lever 28, moves cleat 29 half a step together with frame 30. Button switch 47 reverses the rotation of motor 1 and cleat 29 and frame 30 move another half step. Thus the measuring of the next row progresses in the reverse direction and so on, until finally button switch 48 stops the motor 1.

Abstract: 1,188,946. Variable length propeller blade. WESTLAND AIRCRAFT Ltd. 6 Oct., 1967 [24 Oct., 1966], No. 47724/66. Headings B7V and B7W. A blade of a variable diameter propeller or rotor, e.g. for a convertiplane, comprises a spar 11 along which the blade 10 is retractable and extendable, the twist of the blade being varied during the final stages of retraction. The blade 10 may be retracted by the rotation of the spar 11 engaging a recirculating ball nut 15 formed integral with an outer spar 14 which is prevented from turning by splines 16 which engage splines 18 on the end of a rod 17 rotation of which varies the blade pitch. The blade pitch may additionally be varied during retraction of the blade by making the splines 16, 18 helical. The blade 10 may comprise ribs 13 each with keyways to engage helical splines 19 on the outside of spar 14. The blade is usually held against stops 25 due to the centrifugal acceleration. The blade has at its inboard end a boss 21 containing racks 22 which engage pinions 23 which move with the spar 14. During the final stages of retraction, the pinions 23 are forced to turn as further racks 24 engage thrust bearings 28, thereby causing the ribs 13 to slide along the splines 19 causing the blade to twist.
