Filed: 1942-03-31
Abstract: 545,180. Closures for containers. BJERLING, O. B. March 31, 1942, No. 4275. [Class 125 (iii)] A receptacle 1 to contain foodstuffs or like materials has an opening 15 closed by a cover 5; the peripheral flange 3 of the container end outside the opening 15 has a channel 6 with ridges 7, 8 on each side of it adapted to engage in grooves 9, 10 in the cover. Rings 11 of resilient material are placed between the ridges and grooves The cover may be put on under vacuum, and it can be easily released by piercing it above the channel 6 with a pointed tool. If desired, the cover can be put on under vacuum before the bottom at the tin factory, and the receptacle filled from the bottom end at the filling factory; the bottom can then be attached in the usual way by folding or in any other way. Instead of the space 6 being channelled it may be bounded by flat surfaces between flat sealing rings. In a modification only one flat sealing ring is used, and this has a number of openings so that when the receptacle is closed by the cover separate cells are formed, each of which has to be broken to enable the cover to be removed.

Abstract: 1502322 Water-proofing building materials NYA ASFALT AB 31 Jan 1975 4331/75 Heading DIP A composition containing a liquid continuous phase and a discontinuous phase of deformable "particles" comprising a hydrophobic substance, at least one third of the "particles" having a "particle" size of not less than 0.1 micron is used to impregnate inorganic building materials so as to render them repellant to liquid water whilst maintaining sufficient permeability to water vapour to allow moisture to evaporate from the material, the liquid of the continuous phase then being removed by evaporation. The deformable "particles" may consist entirely of hydrophobic material and may be a liquid or semisolid. Alternatively the "particles" may comprise globules of a solution of a hydrophobic material in e.g. petrol, the globules being dispersed in e.g. an aqueous continuous phase. The hydrophobic material may be a silane, e.g. ethyl, butyl and hexyl trimethoxysilane, methyl, ethyl, propyl or butyl -tri (2-methoxyethoxy)-silane or -tri (ethoxy-ethoxy) silane, phenyl triethoxy silane, cresyl triethoxysilane, hexamethyl disiloxane, hexaphenyl-disiloxane, dimethyltetraphenyl-disiloxane or tetramethyldiphenyl disiloxane, hydrolysed silanes and polysiloxanes i.e. silicones. Preferably the continuous phase is water or a mixture of water with a smaller amount of methanol, ethanol or propanol. The particles are preferably 0.1 to 10 microns in size and comprise 5-25% by volume of the composition. The composition may be applied by a brush or sponge, by spraying or by suction. The building material may be sand stone, lime stone, bricks, mortar, concrete and asbestos cement. In example 7 the building material is washed with hot water before impregnation with the hydrophobic deformable "particles".

Abstract: 555,016. Mechanical presses ; moulding plastic substances ; linkwork. GOLDING, W. F., and NUELL, A. P. April 1, 1942, No. 4341. [Class 87 (ii)] [Also in Group XXIV] To limit the downward pressure which can be applied to a vertically-movable lower plunger B, the pressure is transmitted by levers 1, 4 and 14 to the pivot 13 of a diamondshape toggle frame anchored at 12 to the press, the ends 11 of the frame being drawn together by a tension spring or springs 10, the tension in which may be adjusted by means of nuts 20. The upward pressure at the pivot 13 may be initially adjusted by hanging weights on the pivot, adjusting the spring or springs to balance the weights, and then removing the weights. It is stated that when the angle formed by contiguous members 9 of the frame at the ends 11 is approximately 52 degrees, an approximately constant load is applied by the springs 10 to the plunger B. If the plunger B is depressed unduly, the resistance offered by the springs will decrease because of the increased mechanical advantage afforded by the links 9.

Abstract: 1502013 Flexural resonators CITIZEN WATCH CO Ltd 31 Jan 1975 [1 July 1974 (2) 25 Nov 1974] 4374/75 Heading H1E [Also in Division G3] A quartz flexural tuning fork oscillator comprises electrodes on both faces effective to cause vibration in the plane of the fork. The end of the fork is mounted by means of solder or an adhesive cement which provides electrical connections to the electrodes. The plate may be a Z-cut modified, e.g. by rotation about the X- axis through an angle of up to 15 degrees. Thus in a rectangular plate the length may be parallel to the Y<SP>1</SP> direction and the width parallel to the X direction. The signal field is predominantly parallel to the latter direction. Thus, in the resonator of Fig. 1, the arrangement of interdigitated electrodes 3a, 3b, 3a<SP>1</SP>, 3b<SP>1</SP> produces fields 13a, 13b opposed in direction on either side of the longitudinal axis of each tine of the fork. This causes flexural vibrations in the plane of the tines. The vibrator is tuned by removing parts of the loading plates 5a, 5b using a laser, thinner plates 6a, 6b being provided for fine tuning. It is attached to a pedestal 7 forming part of a capsule by solder or conductive cement 9.

Abstract: 475,238. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 15, 1937, No. 4512. Convention date, Feb. 14, 1936. [Class 38 (iv)] Arcs.-In a flash welding machine the gradual feeding together of the work pieces is controlled according to the current in and/or voltage across the electrodes by means of a grid-controlled vapour discharge tube 18 in the armature circuit of a feeding motor 10, the upsetting of the heated members being effected by the automatic reversal of a second motor 8 after a certain feeding movement. The slide 6 is attached by a ball bearing joint to a rod 7 which is splined to a worm wheel 9 driven by the motor 8 and screwed into a worm wheel 12 driven by the motor 10. When the switch 21 is closed these motors operate in opposition to produce a slow feed of the slide 6, but the fall of voltage in the winding 15 of the welding transformer 14 which occurs as the welding current grows causes an increase in the impedance of the tube 18 and a fall in the speed of the motor 10. Thus, the feeding rate is continually adjusted to maintain a constant welding current. When the slide 6 has advanced sufficiently a switch 22 reverses the motor 8 and the work pieces are upset, the opening of switches 21 and 23 being also effected by the projection 20 from the slide 6.

Abstract: 1390296 Steering column DAIMLER-BENZ AG 30 Jan 1973 [3 Feb 1972] 4528/73 Heading B7H A vehicle steering arrangement having an inclined steering column consisting of a steering shaft 3 and an outer tube 5 which may be shorter than the shaft 3 and which is attached to a mounting in the region of the instrument panel, also includes a member (which may form part of the shaft 3 or its supporting arrangement) which is inclined at a steeper angle than the tube 5, the arrangement being such that, in the event of a collision which deforms the front of the vehicle, e.g. moves the steering gear 2 towards the passenger compartment, the tube 5 is pivoted about its mounting so that the steering wheel 4 moves towards the vertical. This ensures that the driver's body strikes the steering wheel 4 square to the wheel 4 and in the chest region. Steering wheel 4 may also be moved towards the driver to increase the effective energy absorbing path of any deformable elements, e.g. a deformable body 9. In a first embodiment (Fig. 6) the steering shaft 3 includes a deformable member 8 which is mounted in eccentric holders 12 so that, when the steering wheel is in its neutral position, the member 8 is inclined at a steeper angle than the upper part of the shaft 3. The outer tube 5 is pivotally mounted on a bracket 11 by a joint 10 which can also slide along a slot 13. In the event of a collision the member 8 deforms in such a way that the steering wheel 4 moves towards the vertical and towards the driver. In a second embodiment (Fig. 8) the shaft 3 is articulated by a joint 15 and the lower section is inclined at a steeper angle than the upper section of shaft 3. The outer tube 5 is slidably mounted in a pivotal bracket 16. A guide rail 17 is provided which, in the event of a collision, guides the joint 15 to position 15<SP>1</SP>, the steering wheel 4 moving to the position shown in dotted lines. In a modification (not shown) the mounting 16 permits pivotal movement only and the guide rail 17 is omitted. In a third embodiment (Fig. 9a) the steering column 5 is supported at its forward end by a bar 20 which is inclined at a steeper angle than the column. In the event of a collision the bar 20 turns the column 5 about mounting 19 so that the steering wheel 4 moves towards the vertical.

Title: Production of salts of mercaptothiazoles
Inventor: WILDE BERTRAND ERNEST
Filed: 1959-02-10
Abstract: A water-insoluble metal salt of a mercapto-thiazole or -isothiazole is prepared by reacting a water-soluble salt of the mercaptan with a water-soluble salt of the metal in an aqueous medium, the resulting insoluble metal mercaptide being contacted with ammonia or an amine present in the aqueous medium during or after formation of the insoluble salt.  The metals are preferably those, such as zinc, cadmium and mercury, which are capable of forming water-soluble ammine complexes with ammonia or an amine. Specified mercaptans include 2- and 4-mercapto thiazoles and mercapto-aryl thiazoles; alkyl and aryl substituents may be present.  The ammonia or amine may be used in amounts of up to 10% by weight of the mercaptan. Specified amines include methylamine, dimethylamine and ethylamine. In a typical example, aqueous ZnSO4 is added to a hot solution of 2-mercapto benzthiazole in aqueous Na2CO3 whereupon a precipitate of the zinc mercaptide is formed and aqueous NH3 is added and the product is filtered off; in a comparative experiment, the ammonia addition is omitted yielding the zinc mercaptide more contaminated with free mercaptan.

[Also in Group XXX] Planks of sawn timber are sorted according to length by a longitudinal conveyer with a series of unloading stations each having a set of switches operating means to dislodge all planks less than a certain length. As shown, a conveyer formed by endless chains 12 driven by a motor 14 through chain 15 and sprocket wheel 17. The conveyer is inclined transversely to the horizontal at about 10 degrees and planks 25 on the conveyer co-operate with switches 20, 21, 22 on a wall 19 alongside the conveyer. Each plank co-operates with tongues 23 and first opens switch 20 then closes switch 22 and if it is sufficiently long opens switch 21 before switch 20 is allowed to close. If, however, the plank 25 is shorter than the distance between switches 20, 21, the circuit will be closed, thus energizing a solenoid 24 and releasing an arm 27 pivoted at 28 to dislodge the plank from the conveyer to shoots 30. In a further embodiment, switches 20, 21 are normally open and switch 22 normally closed. The Provisional Specification states that light-sensitive cells may replace the switches.
