Title: Improvements in or relating to the catch-bolt of bolts, latches and the like
IPC: E05B15/14
Filed: 1934-01-09
Abstract: 431,675. Locks, latches, &c. BERRYMAN, J., Edgecumbe Cottage, Amberley, Gloucester, and BERRYMAN, C. C., 4, Lanark Mansions, Maida Vale, London. Jan. 9, 1934, No. 2557/33. [Class 44] A latch bolt 2 is shot by a counterweight 5 mounted on the spindle 6 and connected to the bolt by an arm 4. A handle 8 on one side of the lock turns the spindle 6 and lifts the weight to extract the bolt, and a handle 13 on the other side, when turned in one direction, operates a member 11 to lift the weight 5 and extract the bolt, and when turned in the opposite direction turns the member 11 so that a recess 20 engages a heel 19 on the arm 4 and locks the bolt against withdrawal. The member 11 may be moved from locking position and the weight 5 lifted by a key inserted through a guide 24 to engage an aperture 22 in the member 11, as shown in Fig. 7. In the form shown in Fig. 8, the arm 4 engages a notch 28 on the bolt, and the means for actuating the bolt from the inside or locking it against withdrawal consists of an arm 31 carried by the spindle 29 of the inside handle 13. When the arm 31 is turned clockwise, it engages the weight 5<a> and turns it on its axis 6 to retract the bolt ; when turned anticlockwise it engages a slot 30 in the bolt and locks it. Specification 431,491 is referred to.

Title: Insulating coating and methods of applying the same
IPC: C04B28/26
Filed: 1944-02-17
Abstract: A process of applying a neutral coating on iron and steel includes the step of first mixing alkaline earth oxides with silica and then adding this mixture to an aqueous solution of sodium silicate and applying a second coating of the same ingredients plus asbestos after the first coating.  Calcined dolomite is the preferred alkaline earth oxide and a fluoride, e.g., calcium fluoride may also be present in the coatings. Preferably the first coating is prepared by mixing 1 4/5 parts of silica, 1/8 part of calcined dolomite and 1/8 part of calcium fluoride, then two parts of this mixture are added to one part of the silicate solution slowly and with stirring to form a paste when further solution is added.  The second coating is prepared in the same manner with the addition of one part of asbestos to four parts of the silica mixture.  The second coating after application may be treated by spraying with a weak solution of acid such as hydrochloric acid.

Title: Improvements relating to the conversion of waxy hydrocarbons
IPC: C10G45/62
Filed: 1962-01-26
Abstract: Oils having a higher isoparaffin content than the feed are obtained from waxy hydrocarbons at elevated temperature by contact with hydrogen and a catalyst comprising a platinum group metal, an halogenatable refractory inorganic oxide support and at least 1% fluorine obtained by contacting the support with XY2F2 in which X is carbon or sulphur and Y is hydrogen or fluorine under conditions which do not destroy the oxide structure or give free fluoride or volatile metal-fluorine complexes.  The reactions occurring are stated to be isomerization and isocracking with some aromatization and cracking and, if sulphur is present, desulphurization. The feed should contain at least 10%, preferably at least 50%, wt. of waxy hydrocarbons.  Conversion is effected at 500-1000 DEG  F., 0-3000 p.s.i.g., 0.01-10 v./v./hr. and up to 15,000 SCF of hydrogen per barrel of feed, using a fixed fluidized or moving bed of catalyst and liquid, vapour or mixed phase conditions.  The products boiling in the kerosine, gas, oil and lubricating oil ranges are dewaxed before and/or after fractionation and waxes may be recycled.  The catalyst is preferably treated with carbon tetrafluoride under non-reducing conditions to introduce up to 15% wt. of fluorine or 1.2-3.4 x 10-4 g. fluorine/sq. metre of surface area.  Suitable oxides are those of aluminium, boron, silicon, titanium and zirconium.

Abstract: 1299205 Amylose powder; amylose-butanol complex HAYASHIBARA CO 22 Jan 1970 [24 Jan 1969] 3241/70 Heading C3U Amylose powders of good solubility and flavour retention are produced by gelatinizing a starch slurry, hydrolysing the branches of amylopectin with an isoamylose thereby obtaining an amylosic starch solution, precipitating the resulting starch to the form of a crystalline precipitate by slowly cooling the starch solution, separating the precipitate either by decantation or centrifugal separation, and thereafter spray drying the separated crystalline precipitate to a powdery form. The precipitation and separation of the amylose from water can be achieved simply by the cooling or, alternatively, with the addition of butanol or a fatty acid to produce, after the cooling, a precipitate in the form of a complex, e.g. an amylose-butanol complex. The initial hydrolysis may be achieved by heating or with enzyme.

Title: Improvements relating to direct voltage stabilisers
Inventor: HAVARD PETER DAVID
IPC: H02M3/156
Filed: 1957-01-31
Abstract: 882,994. Automatic voltage control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 31, 1958 [Jan. 31, 1957], No. 3368/57. Class 38 (4). [Also in Group XL (c)] The D.C. voltage applied to a load is stabilized by connecting a capacitor across the load and charging it intermittently from a D.C. source through a switching transistor or discharging it through a shunt transistor, the "on/off" ratio being controlled in accordance with deviations in output voltage. The load 12 and capacitor 13 are supplied from a rectifier 3 through parallelled transistors 6, 7. The load voltage is detected by an emitter-coupled pair of transistors 31, 32. The base potential of transistor 31 (and hence the emitter potential of both transistors) is stabilized by a Zener diode 35, and the base potential of transistor 32 is proportional to load voltage so that with transistors 6, 7 conducting and the load voltage increasing, the collector potential of transistor 32 becomes less negative causing the transistor 24 to be cut off. Transistor 24 is cross-coupled with a transistor 23 to form a bi-stable pair, hence transistor 23 now conducts causing the two-stage emitter-follower amplifier 17, 16 to cut off and so cut off the switching transistors 6, 7. The resulting fall in load voltage reverses the above and the cycle repeats. Transistors 6, 7 and 16 are arranged to bottom when conducting to reduce power losses. Reference has been directed by the Comptroller to Specification 853,340.

Title: Improvements relating to the preparation of sulphates

Filed: 1942-03-16
Abstract: 561,937. Sulphates. OCEAN SALTS (PRODUCTS), Ltd., and ADAMS, B. A. March 16, 1942, No. 3428. [Class 1 (iii)] The sulphates of elements, the base or basic salts of which can react with sulphuric acid to form water-soluble salts, are prepared by the combination of steps comprising contacting a solution containing sulphuric acid with an acidadsorbing material and then contacting the acid-charged material with a solution or suspension of the base or basic salt in question. The method is employed for obtaining sulphates from dilute wastes from chemical processes. A solution of the sulphate so obtained may contain an excess of the base and be passed through a further bed of acid-charged material. Example.-A solution containing sulphuric acid and sodium sulphate was passed through a bed of meta-phenylene diamine resin through which was then passed a suspension of basic magnesium carbonate. Further magnesium carbonate was added and the solution again passed through the bed and so on to obtain a relatively strong solution of magnesium sulphate.

The first slide means comprises flexible fingers 368 which engage the lower edge of the foremost plate 26a, withdraw it from beneath pressing arms 310 and raise it to intermediate station 122 where it is supported by spring arms 176. Fingers 370 on the first slide means, simultaneously with the forgoing separation, forward a previously separated plate 26b to an inspection station 124 where it may be viewed by an operator. The slide 136 then returns to its starting position. The second slide 132 carries plate engaging fingers 402 which press on the back of the plate at the inspection station and pivot plate-supporting lever 204 to the right to deliver the plate to the vertical position whereupon it is moved downwardly by the slide 132 into the printing position 20. This downward movement of slide 132 returns a previously used plate to the magazine by engagement of its rear edge by further fingers 418. Return movement of the second slide means registers the plate previously moved to the printing position against a stop on lever 198. The plate is held in register position by a lever 240. Levers 326 bias the re-stacked plates away from the path of movement of the second slide means to permit further plates to be stacked. The magazine as a whole is biased to the right (as shown) and is removable.
