Title: Dry battery cells
IPC: H01M2/02
Filed: 1973-11-02
Abstract: 1412895 Dry cell casing TUDOR AB 2 Nov 1973 [22 Nov 1972] 51071/73 Heading H1B The zinc container 5 of a Zn-MnO 2  cell is surrounded by a fluid-tight film 6 pressed against the bottom of the container by a cup-shaped contact member 10, the contact member making contact with the container at 11 and 12 and may be welded thereto at these points. A portion 15 of the film 6 overlies the top of the cell. Absorbent layers 7, 8, e.g. of highly absorbent pasteboard, for leaked electrolyte are situated, respectively, around the side and at the top of the cell. The layer 7 is between the film 6 and outer plastics case 4 and the layer 8 is between a lid 9 and the film portion 15. In a modification (Fig. 2, not shown) a further absorbent layer is positioned between the film portion 15 and the cell top 2 and the layer 7 is omitted.

Title: Improvements in or relating to transparent members
IPC: C09K3/18
Filed: 1965-12-02
Abstract: 1,111,590. Films having hydrophilic surfaces. O. H. DRAGER, [trading as DRAGERWERK HEINR. & BERNH. DRAGER]. 2 Dec., 1965 [5 Dec., 1964], No. 51311/65. Heading B5B. [Also in Division G2] A process for the production of a transparent film or sheet formed from an artificial plastics material having one or more saponifiable groups and having an hydrophilic surface substantially resistant to misting, comprises treating a surface of said film or sheet with an alkali or an acid and thereafter treating the resulting surface with an acid or an alkali respectively, whereby there is obtained a transparent film having an hydrophilic surface substantially resistant to misting. Suitably, the artificial plastics material is a cellulose or a cellulose derivative, especially a cellulose ester, and the treatment of the surface with an acid or an alkali may be carried out in the presence of an oxidizing agent or a reducing agent. The surface may be subsequently treated with a wetting agent, suitably a sulphonate, in the presence of heat. For example, the surface so treated, cleaned with water and dried, may have its treated surface thinly coated with a wetting agent concentrate and heated to 60‹ to 80‹ C. for a short time in a drying chamber. The excess wetting agent may then be rinsed off and the surface dried. It is also possible to use chemical reactions of the saponified cellulose ester with sulphonates or other suitable substances in order to increase the hydrophilic effect. Such surface treatment may be applied to films and sheets used as visor windows or clear-vision windows for respiratory apparatus masks or diving masks, as such treatment obviates the risk of the window becoming clouded with precipitation of moisture on the visor window. The inside surface of such windows can receive condensed water vapour in any quantity and water can flow off the surface again without the hydrophilic properties of the surface becoming less effective on prolonged use, since owing to the hydrophilic behaviour of the surface, a coherent film of water forms thereon and the window remains clearly transparent.

Patent GB-515270-A (GB)
Abstract: 515,270. Calculating-apparatus. LAGERMAN, T. May 27, 1938, No. 15921. Convention date, May 28, 1937. [Class 106 (i)] In a calculating machine provided with a rotor composed of setting disks 3 each provided with shiftable teeth 4 moved by setting members disposed opposite the teeth to be actuated and operated. by keys 15, the teeth being-shifted without turning any part of the disc and the setting discs being brought in succession into setting position by stepwise axial displacement of the rotor, the setting members comprises pins 5', 6<SP>1</SP>, 7<SP>1</SP> and 8<SP>1</SP> displaceable in a plane parallel to the setting disks and adapted upon actuation of the corresponding key to be displaced into engagement with the corresponding teeth. Each key 15 operates a lever connected with detents cooperating with a rack connected with the rotor. Every operation of a key thus permits spring 23 to move the rotor one step to the left and bring the next setting disc up to the setting members. By forming the teeth as two single teeth 7 and 8, one double tooth sector 6, and one five toothed sector 5 it is possible to set any number from 0 to 9 by only four setting pins each co-operating with one of the units 5, 6, 7 and 8. The teeth 4 are each provided with snap action springs. The setting discs are all zeroized at the end of a calculating operation by cams 37 on a member 36 mounted on pins 38 working in slots and operated by a lever 24 connected to the rotor when the latter is in its extreme position. Each key 15 carries a finger 33 which, when the key is actuated to set a digit, moves a numeral sector 27 through a lever connection,. and the value of the digit is exhibited through opening 29. The sectors 27 shift with the rotor and are each locked in position when its particular disc is set, by bar 34 passing through one of a number of perforations 35 in the sector.

Title: Control devices for hydraulically-operated piston units
IPC: F15B11/02
Filed: 1971-11-10
Abstract: 1372593 Fluid-pressure apparatus MASCHINENFABRIK UND GIESSEREI NETSTAL AG 10 Nov 1971 [19 Nov 1970] 52315/71 Heading F1P A control device 4 for an hydraulic piston of an injection screw in a plastics injection-moulding machine includes lines 1, 2, 3 connected to the pressure side A of the piston, a tank T for the hydraulic fluid and a source P of pressurized hydraulic fluid and controlled by lands 14a, 14b, 14c of a valve-member 14, which moves axially in accordance with fluid-pressures in chambers 16a, 16e and the loading due to a compression spring 21, the pressure in the chamber 16a being determined by pre-set valves 5, 6. The chamber 16e contains a piston 22 with bores 24a, 24b interconnecting the ends of the chamber. To transfer connection of the side A from the source P to the tank T an electromagnetic valve 7 is set to the position shown in Fig. 1 so that pressure from the source is applied to the right-hand side of the piston 22 through a passage 23a and thus displaces the member 14 to the left (as indicated by broken lines in Fig. 3), the valve 5 being open to the tank, the valve 6 shut and the left-hand side of the chamber 16e connected permanently to the tank through a line 25. The setting of the valve 5 fixes the left-hand position of the member 14 and therefore the flow between chambers 16c, 16d. To restore connection of the side A to the source P the valve 5 is shut, the valve 6 opened to the tank and valve 7 reversed, Fig. 2 (not shown), the setting of the valve 6 determining the right-hand position of the member 14 and therefore the flow from a chamber 16b to the chamber 16c. Further adjustment of the right-hand position can be obtained by shifting axially a "feeler" 23, the piston 22 adopting a position in which it is separated somewhat from the feeler owing to the flow through the bores 24a, 25b and passage 23a. The valve 5 may be dispensed with and the valve 6 adjusted electrically with the aid of a selector switch (60), Fig. 4 (not shown).

The pin is accommodated in a transverse slot in the pulley enabling movement in either laterally-spaced arcuate paths. The complete scanning cycle may be produced during two rotations of the drum, when the drive and idler members have the same diameter Figs. 3-6 (not shown) or during one rotation of the drum, when the diameter of the idler member is less Figs. 7 and 8 (not shown). In the former case, as shown, pin 72 (driving pulley 32) is integral with a lead chain 64 which passes round rotary elements 67 and 68 and mates with surface patterns on drive and idler members 53 and 66, resp.

Two or more gases are mixed in proportion by passing each gas down a conduit 5a or 5b with a constant pressure drop and have the gases maintained at constant absolute pressures at both the inlet and outlet of the conduit by regulators 4a, b, 6a, b. The conduit may comprise a capillary tube 5a or 5b or a tube filled with an inert granular or calcined material, and a conduit may be preceeded by a plurality of such conduits each with a different pressure drop and connectable in parallel to give the necessary gas flow for the desired proportion. The mixture is obtained either by passing each gas singly through the conduit for a given time at given pressures into a reservoir or by passing each gas continuously through its own conduit and combining the gases at a common outlet 14 for a continuous discharge. In another embodiment (Fig. 5, not shown) each constituent gas supply is connected by a multiway cock (20) to a single conduit (5) and the cock operates automatically to pass the gases singly for various time periods into a reservoir (22).
