Title: Medical drainage collection assembly
IPC: A61M1/00
Filed: 1973-05-03
Abstract: 1435771 Fluid withdrawing apparatus C R BARD Inc 3 May 1973 [9 Aug 1972] 21083/73 Heading A5R Fluid Withdrawing Device: A fluid withdrawing device 60, Fig. 1, comprises a rigid container 62, a lid 64 having a fluid inlet port 70 and an evacuation port 66, and a flexible sack 76 for receiving fluid through the inlet port 70, the sack 76 having multiple walls with apertures 90, 92, Fig. 8, in their upper portions for preventing collapse of the sack 76 upon evacuation. Containers: The container 62 may be graduated by indicia 78. The lid 64 is sealed to the container 62 by means of an annular bead 114 on the rim of the container 62 and a mating groove 142 in the lid 64. The container 62 may be made stackable by providing a shoulder (206a), Fig. 16 (not shown) between a cylindrical portion (202a) and a frustro-conical portion (204a), and projections (210a) in the lower portion of a container (200a). Two containers (220, 224), Fig. 18 (not shown) may be mounted on rollers for greater mobility, and the two containers (220, 224) may be connected in parallel using Y- connectors (230, 238), to increase the capacity of the drainage device. Ports: A fluid inlet port 82 is mounted in a concave lid 64 and has a diaphragm 134 connecting an inner member 130 with a conduit 72 for a drainage tube 74. The diaphragm 134 provides resiliency so that the inner and outer members 130, 132 of the port 82 can combine more firmly to form a seal when the container 62 is evacuated. Sacks: The sack 76 is generally flat and rectangular and is made of a transparent plastics material such as polyethylene modified with ethyl vinyl acetate. At its top the sack 76 supports the port 82 and is sealed thereto. The apertures 90, 92 in the inner and outer sacks are formed in staggered relationship to act as a baffle against splashing liquid. A line of perforations 112 is defined in the sack 76 so that it can be easily torn to empty the contents of a full sack. The apertures 90, 92 are defined by semi circular or quadrant shaped slits separated by hinges 170. Levers: Levers 94, 96 are provided under the lid 64, for separating the sack 76 from the lid 64. The levers 94, 96 are supported with end portions thereof disposed between. the underside of the lid 64 and the port 82. When pads 124, 126 on the opposite ends of the levers 94, 96 are depressed manually, they separate the sack 76 from the lid 64. A float valve member 97 is located above the lever 96 and acts to close the evacuation port 66 when the fluid in the container 62 overflows. The valve member 97 is shaped to accommodate part of the port 82. A U-shaped cut-out portion (194), Fig. 11 (not shown) provides greater flexibility to the valve member 97. In an alternative embodiment, an arm (314), Fig. 20 (not shown) is slidably supported on top of a container (300) by a post (314). A cylindrical projection (316) on the arm (314) is used to dislodge the fluid inlet port from the lid of the container 300.

Title: Improvements in and relating to door locks
IPC: E05B55/06
Filed: 1936-07-30
Abstract: 461,865. Latches and locks. RIEGER, W. July 30, 1936, No. 21085. [Class 44] In a door fastening of the kind in which a bolt normally acts as a spring-shot latch bolt withdrawn by handle, but can be shot further into the keeper by means of a key, to act as a lock bolt, a key-operated locking tumbler 3 is in the form of a lever pivoted on the bolt 2 at 9, the rear end 13 being in the form of a hook normally engaging a pin 12 on the follower 4 under action of a spring 10. The latch bolt can thus be retracted by handles 5, 6 against the action of spring 19 mounted on the bolt and bearing against a fixed stop 18 on the casing 1. A spring 14 normally holds the follower against a fixed stop 15. The other end of the tumbler carries a pin 17. When the key 8 is inserted and rotated clockwise the bit engages notch 16, raises the lever so as to disengage hook 13 from pin 12 and then shoots the bolt, carrying the hook 13 clear of pin 12, so that the handles are inoperative. Pin 17 is carried over to the right of stop 18 and co-operates therewith to retain the bolt shot when the key is withdrawn. In the locked position, spring 19 rests against a projection 20 on the bolt. To economize space the bolt is slotted vertically to provide jaws between which the tumbler and spring 19 are housed, the jaws having apertures 7 to give clearance for the key operation. The case 1 is of height sufficient just to accommodate the bolt.

Title: Ticket-cancelling machines
IPC: G07B11/11
Filed: 1972-05-06
Abstract: 1392846 Ticket apparatus NATIONAL RESEARCH DEVELOPMENT CORP 1 May 1973 [6 May 1972] 21251/72 Heading G4T Apparatus for severing lengths representing fare or fee units from a strip of ticket material, the initial length of which is related to the number of fare or fee units paid for in advance, checks various dimensions/shapes/properties of the strip and does not operate on the strip if any of the checks gives a negative result. In the embodiment shown, the ticket strip 10 (also Figs. 1 and 2, not shown), is formed with two longitudinal score lines and assumes a truncated V-cross-section when inserted in a similarly sectioned channel 20. Such insertion pivots a lever 28 which opens a switch 32 to provide an indication that a ticket has been inserted), and closes a switch 34 (to indicate a ticket thickness greater than a predetermined minimum). An upper limit on acceptable ticket thickness may be set either by the dimensions of the channel 20 or by limiting the pivotal range of the lever 28. The leading end of the ticket strip, if of the correct formation, displaces pins 26 (mounted in a truncated V-section array), to close microswitches 27. Upon closure of switch 34 and switches 27 a motor 39 is energized via a relay (not shown), and drives a shaft 40, which through a cam 53 closes a switch 52 to provide a holding circuit for the relay when switches 27 are subsequently opened. Rotation of an eccentric (not shown), on shaft 40 operates a guillotine 38 to sever the appropriate ticket length. To provide for selection of this length, either the position of block 25 relative to guillotine 38 is adjustable or more than one selectively operable guillotine is provided. Immediately following severance, a cam 45 permits a spring 48 to raise a gripper 53b thus freeing the ticket strip for withdrawal. Severance also causes opening of switches 27, but the motor relay remains energized through switch 52 and a further switch (50, Fig. 4, not shown), the latter opening to de-energize the motor when shaft 40 has completed a half-revolution. When the ticket strip is withdrawn, switch 32 closes and through switch 52 re-energizes the relay and the motor. The full revolution cycle terminates when switch 52 opens. A bell 56 is automatically rung immediately after severance. The apparatus may be linked to gate or turnstile freeing mechanism. The translucency of the ticket strip may be checked by a photo-electric cell 61, which receives light from a source 60 via optical fibre 62 and the ticket strip. In severing, a notch may be cut in the free end of the remaining ticket strip at a selectively adjustable transverse location on the strip.

Title: Self-sealing cable
IPC: G02B6/44
Filed: 1973-05-04
Abstract: 1420365 Cables PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 May 1973 [9 May 1972] 21331/73 Heading H1A Cable sheath 1 encloses a composite filler material 3 which not only swells but also changes colour, wherever moisture gains access to it. Water penetrating the sheath is restrained from spreading axially by the swelling material, of a polymeric organic substrate, which seals the interstices between the insulated conductors 2. The sealing action may be enhanced by the addition of a gas-evolving filler ingredient, e.g. calcium carbide or hydride. A colour change, from light yellow to blue, which indicates the extent of the penetrated region when the cable is cut for repair, is obtained by use of potassium ferrocyanide and ferric ammonium sulphate, mixed in the filler material. One embodiment uses a mixture of 98% by weight of a methoxycellulose swelling agent with 2% by weight of the colour agents named above.

Title: Improvements in vacuum regulating apparatus
IPC: F04F9/08
Filed: 1927-08-15
Abstract: 276,333. General Electric Co., Ltd., and Weintraub, E., (Assignees of Soc. Alsacienne de Constructions MÚcaniques). Aug. 17, 1926, [Convention date]. Vacuum gauges.-The periodic automatic operation of a MacLeod gauge controls vacuum pumps and/or inlet valves to regulate the vacuum in an enclosure, such as a mercury vapour rectifier. A signal may also be actuated. A rectifier may be put out of action when the vacuum is bad by opening a circuit introducing a resistance &c. A rotary interrupter 7, controlled, e.g. by clockwork, periodically puts into action an electric motor 6 which actuates, through a worm wheel 10 and a clutch 17, a winch 11 to lift the mercury reservoir 3 of the gauge. A stop prevents the reservoir from rising beyond a certain point, and a torque limiter 18 then allows the motor to slip. This limiter may comprise friction discs spring pressed together; it may in some cases be omitted. A brake 19 retards the descent of the mercury reservoir. The gauge is described in Specification 264,759. and the vacuum vessel is connected to it at the part 2. Its capillary tube 5; Fig. 2, is fitted with electrodes 20, 21, 22, connected in a control circuit 23 closed by the mercury column. At the electrode 22 a signal is made indicating the excellence of the vacuum; at the electrode 21, the vacuum should be started up; at the electrode 20, the circuit breakers which protect the rectifier are opened or a series resistance limiting the current introduced &c. These effects are obtained through the excitation of relays 27 by coils 24 which are supplied with current from the electrode circuits through bimetallic strips 33 heated by resistances 30. There is thus provided a delay in the action until the mercury in the tube 5 has settled down after its oscillations. The relays or strips 33 have different periods of action, the period being greater for the lower strip; and the heating coils of the lower strips are controlled by the upper circuit; so that the upper effect is first made and simultaneously the circuits for the lower effects are broken.

The recess m then engages the bracket k and locks the rod e. This lock cannot be released until the rod e is lowered by the closing of the guard. The auxiliary guard is locked by a bracket abutting against the main guard.
Patent GB-423933-A (GB)
Title: The manufacture and application of new quaternary ammonium compounds
Filed: 1933-08-02
Abstract: Quaternary ammonium compounds are obtained by reacting alkyl or aralkyl esters of inorganic acids or of aromatic sulphonic acids with the products described in Specification 423,864, i.e. the products obtainable from polyethylenepolyamines of the formula NH2 (C2H4NH)nC2H4NH2 and compounds containing at least two acylating groups or at least one acylating and one alkylating group, which products may be after-treated with alkylene oxides.  The quaternary ammonium compounds are useful for after-treating cellulosic materials dyed with substantive dyes, to improve the fastness of the dyeings. Examples are given of the preparation of quaternary ammonium compounds from (1) dimethyl sulphate and a product obtained, as described in example 1 of Specification 423,864, by treating with ethylene oxide the reaction product of a polyethylenepolyamine mixture and cyanuric chloride; (2) dimethyl sulphate and a product obtained, as described in example 2 of Specification 423,864, from a polyethylenepolyamine mixture and cyanuric chloride; (3) dimethyl sulphate or methyl p-toluenesulphonate and a product obtained, as described in example 2 of Specification 423,864, by reacting a polyethylene polyamine mixture with a condensation product from one mol. of cyanuric chloride and 2 mols. of monoethanolamine; (4) dimethyl sulphate and a product obtained, as described in example 3 of Specification 423,864, from a polyethylenepolyamine mixture and oxalyl chloride or a product obtained, as described in connection with sample 3 of Specification 423,864, from a polyethylenepolyamine mixture and chloracetyl chloride; (5) dimethyl sulphate and a product obtained, as described in example 4 of Specification 423,864, from a polyethylenepolyamine mixture and biuret.  The process may be modified by conducting it in two stages; in the first stage the secondary amino groups in the starting materials are converted into tertiary amino groups, for instance with methyl chloride, methanol and hydrochloric acid, or benzyl chloride; in the second stage, the tertiary amino compound is converted into a quaternary ammonium compound.  Reference is made also to the consecutive use of a plurality of alkyl or aralkyl esters in the preparation of the quaternary ammonium compounds.  The examples include particulars of the use of the quaternary compounds described therein in treating cotton dyed with a substantive dye such as Sirius blue BR, the treatment being effected with a dilute aqueous solution of the quaternary compound, which may contain other substances such as sodium carbonate.
