Title: Improvements in and relating to locks
IPC: E05B35/12
Filed: 1934-06-18
Abstract: 419,269. Locks. ERAS, V. J. M., 1, Oranjepark, Dordrecht, Holland. June 18, 1934, No. 18027..[Class 44.] In an exchangeable trustee lock detachably secured to pins 15, 16 on the safe door 17 by a hand-operable slide 14 engaging grooves in the pins, the slide is locked against movement by a tumbler 22 pivoted at 29 and biassed by spring 27 to engage a pin 23 on the tumbler in one or other of two branches 24, 25 of a U-form slot 26 in the slide. Tumbler 22 is releasable by a changing key 35 inserted in keyhole 7 and engaging a tumbler aperture 28 having a shoulder 36 limiting movement of the key, which is rotatable anticlockwise, Fig. 5. The lock has an attendant's bolt 2 blocked by a tenant's bolt 5. The bolt 5 is shaped so that when shot its end 5<d> lies close to the pin 34 on which key 35 works so that the bolt cannot be fully shot with the changing key in place and the key cannot be fully inserted when the bolt is shot. Bolt 5 is locked by two sets of tumblers 8, 9 co-operating with pins on the bolt. The pin 31 co-operating with tumblers 9 overlies a projection on, or enters a recess in, tumbler 22 so that the tumbler cannot be released unless the tenant's bolt 5 is retracted. The key 10 operating tumblers 8, 9 and bolt 5 is inserted in a keyhole 11 and can only be removed when the bolt is in shot position. The attendant's bolt 2 is locked by a single set of tumblers 6 and is operated by an attendant's key, which is inserted in the keyhole 7, and can be removed with the bolt either shot or retracted. The bolt has a pin 32 which, when bolt 2 is retracted, engages a recess 33 in tumbler 22 so that the tumbler cannot be released unless bolt 2 is shot. Removal of the lock can only be effected by the use of the three keys, and the door must have been opened and bolt 2 again shot. The attendant's key can only rotate clockwise, Fig. 5, and so cannot be used to release tumbler 22. The slide 14 is operable, when released, by a finger-piece 14<a>, and can only be removed from the casing when in released position with recesses 20 in register with extensions 19 of the end of the casing which overlap the edges of the slide. Thus if the screws holding in place the cover-plate and mechanism of the lock have been removed the lock may still be securely held in place as the slide is not removable from the casing in the locking position. Various modifications are mentioned. Inter alia the tumbler 22 may be movable in the same direction as tumblers 6, the changing and attendant's keys being correspondingly modified, the tumbler 22 may be slidable, and two or more tumblers 22 may be provided, in which case pin 23 would be arranged on the slide 14, and slots such as 26 provided in the tumblers. The tumbler 22 may itself be locked by additional tumblers. The tumblers 6, 8, 9 shown are without springs, but spring tumblers may be used. Tumbler 22 may be independent of bolt 2, pin 32 and recess 33 being omitted.

Title: Encapsulating liquids or solids by interfacial polymerisation
IPC: B01J13/16
Filed: 1966-04-25
Abstract: 1,136,303. Forming microcapsules. WALLACE & TIERNAN Inc. 25 April, 1966 [26 April, 1965], No. 18072/66. Addition to 1,091,141. Heading B8C. The capsules of the main patent are formed by producing droplets of the liquid to be encapsulated (which may contain solids or subsequently become solid), and containing the first intermediate, by injection into the second liquid and flowing the droplets through the second liquid incorporating the second intermediate. The second liquid may flow with or against the droplets which may owe their motion to gravity or buoyancy. In one form of apparatus for carrying out the method, Fig. 1 (not shown) and generally when the first liquid is organic and the second aqueous, droplets are produced at the base of a column (10) containing the second liquid by an intermittently operated valve (25) controlling flow to a jet (13). The second liquid without the intermediate is pumped in adjacent the jet, allowing the droplets to form without encapsulation. The second intermediate is introduced further up the column so that encapsulation takes place from then on to produce the finished product at the top. A collector at the top comprises a spherical vessel (36) connected to the column by a horizontal tube along which air is blown to urge the capsules into the vessel. The latter has liquid and air discharge connections 41, 42 and means (not shown) for removing the accumulated product. In a modification of this form, Figs. 2, 4 (not shown) a sloping passage leads upwards from the column head and capsules, urged by injected air, roll against the roof of the passage, so producing a more uniform skin. In other arrangements, when the first liquid is aqueous, the first liquid is injected at the head of a column with the dispositions of inlets inverted as compared with the earlier described forms, Fig. 6 (not shown). Alternatively the second liquid in reactive form i.e. plus the second intermediate, enters at the base of the column where the downwardly moving capsules are collected, Fig. 7 (not shown). Non-reactive second liquid enters adjacent the jet and both liquids are discharged midway of the column. The jet may have a multi-aperture discharge head. It may be vibrated to assist formation of droplets.

Title: Method for producing glass pots and glass cuvettes
IPC: C04B35/18
Filed: 1932-06-27
Abstract: Relates to methods of making refractory articles, e.g. pots and cuvettes for glass making, made from chamotte and a ceramic binder, and consists in adjusting the sintering temperature of the clay used for making the chamotte by adding finely ground quartz (to raise the temperature) or glass (to lower the temperature) and in using as the binder a porcelain mixture, which just sinters at the working temperature of the article, comprising clay, glass, fine chamotte and medium grain quartz.  The glass used in the porcelain mixture is preferably the same glass as that to be melted in the pot &c.  In an example, the porcelain mixture is made by first mixing equal parts (dry weight) of slimed unctuous clay and glass and then adding 60 parts of fine chamotte and quartz sand to 40 parts (dry weight) of clay-glass mixture in an edge runner mill.  The refractory composition is made by adding 65 parts of coarse chamotte to 35 parts of binder.

Title: Improvements in or relating to the production of polyvinyl butyral films
Inventor: JENSCH WOLFGANG
IPC: B29C55/06
Filed: 1970-04-17
Abstract: 1,271,188. Treating polyvinylbutyral films. DYNAMIT NOBEL AG. 17 April, 1970 [18 April, 1969; 24 Feb., 1970], No. 18578/70. Heading B5B. A process for treating a film of plasticized polyvinylbutyral to remove tackiness, comprises immersing the tacky film in a bath containing a non-solvent for polyvinylbutyral and imparting a matted appearance to both surfaces by calendering the surfaces either simultaneously or successively while the film is immersed in the bath; calendering being carried out at a film surface temperature lying in the range from 5‹ C. above the lowest temperature at which "stamping" can occur to 140‹ C. This temperature is defined as the minimum temperature at which roughening of the film will occur when it is guided between them. The preferred temperature range is from 85‹ to 100‹ C. The fluid in the bath may be water, which can have compounds dissolved in it to raise its boiling point, e.g. water-soluble polyhydric alcohols NaCl, KC1, CaCl 2  and Na 2 SO 4 , or it may consist of water-soluble polyhydric alcohols such as ethylene or propylene glycol or glycerine. In Fig. 1, there is shown an arrangement whereby the surfaces of a film may be roughened in succession. The matting rollers 1 and 2 are heated but the pressure rollers 3 and 4 are not. The surface X is treated first and the surface Y thereafter. The surface X is protected against the thermal recovery that would otherwise occur when surface Y is heated, by the cooling effect of the fluid in the bath. In Fig. 2, both sides of the film are roughened simultaneously between rollers 6 and 7. The rollers 6 and 7 are not directly heated, the temperature being maintained by heating the fluid in the bath. The guide roller 8 may be omitted. The roller speeds may be adjusted so that the film is held under tension or stretched during the roughening process to a draw ratio of from 1.2 to 3.0, preferably to 1.8 to 2.0. Subsequently the film may be allowed to shrink back to its original dimensions, the film thus aquiring a rough base structure on both surfaces, in addition to the matt finish.

Title: Process for manufacturing electrical resistance bodies and machine for carrying out this process
IPC: H01B1/00
Filed: 1926-07-31
Abstract: 256,264. Loewe, S. Aug. 1, 1925, [Convention date]. Coating-machines.-Electric resistances such as high resistances in wireless apparatus are produced by passing mechanically a large number of separate bodies successively before one or more spraying nozzles applying a resistance coating to the bodies. Glass rods or other bodies are held by springs on holders 12 in a wheel 11 continuously rotated by a motor to move the bodies successively past a spraying-device 17 applying the resistance coating of Chinese drawing ink or the like, uniformity of the coating being ensured by rotating the holders 12 and the bodies about their axes by means of rollers 28 on the holders engaging a belt 29 rotated from the motor through a drive 31. A casing 13 vertically movable and balanced by a weight and rope 15 is lowered over the bodies and wheel 11 prior to spraying, the bodies being successively exposed at a slot 16 and being dried by an electric heater within the casing 13. To indicate when sufficient coating has been applied, the resistance of a small proportion only of the total number of resistances produced simultaneously is tested by means of an ammeter 26. In the spraying operation, sprayers may be provided at several points around the wheel 11. The contact between the sprayedon resistance layer and terminals such as silver caps at the ends of the bodies sprayed may be improved by spraying on a cap of Chinese drawing ink, soot, or the like over the silver, the resistance layer being sprayed over the body and over the caps. The caps and the resistance layer may be sprayed on simultaneously or successively. for instance, layers of the cap and of the resistance may be alternately applied from different sides, a shield covering the middle part of the body during spraying the caps. The resistances may be exposed to a heated stream of air during spraying the resistance layer and the caps.
