Title: Improvements in or relating to frames for photographic transparencies
IPC: G03B21/64
Filed: 1959-06-02
Abstract: 859,247. Lantern slides. JOST, J., [trading as FILMOSTO-PROJEKTION J. JOST]. June 2, 1959 [June 12, 1958], No. 18742/59. Class 98(2) A transparency frame comprises two identical frame halves, preferably dowelled, each of which has an opening adapted to receive a glass plate cemented at its edges at the aperture of a field limiting mask which extends over the inner surface of the frame half and to which it may be cemented, the transparency being held between the two masks. Adhesive bonding of the masks to each other or to the frame halves is optional in the preferred embodiment shown in Figs. 1, 7 and 8, the frame halves having diagonally opposed projections 1c and recesses 1d which are slightly bevelled so that when the two frame halves are juxtaposed with the projections of each opposite the recesses of the other, they may be pressed into firm engagement. The opening in the frame halves for receiving the glass plate 2 is of sufficient depth to allow a tolerance on the glass thickness, and the edges 1g of the opening are widened so as to allow the mask to bend slightly in these regions. The corners of the mask must be removed, as in Fig. 8, in order to clear the projections; in order, too that the assembled frame shall have a flush peripheral edge, those parts 1f adjacent the mask surface are depressed by an amount equal to the mask thickness. The inward-facing walls of the L- shaped projections serve to locate the transparency in its mounting position; identification of the front and rear of a transparency is facilitated by specially roughened regions on the frame members for suitable marking.
Patent GB-498398-A (GB)
Title: Improvements in or relating to the manufacture of carboxylic acids from olefines
IPC: C10B7/02
Filed: 1937-07-06
Abstract: Carboxylic acids are prepared by heating an initial mixture of an olefine, carbon monoxide, water or steam, and a boron-halogen compound, e.g. boron fluoride in anhydrous or hydrated form, aqueous solutions of dihydroxyfluoboric acid, hydrofluoboric acid and, generally, acids obtained from hydrogen fluoride and boric acids. Promoters such as powdered metals or oxides, e.g. nickel, or nickel and mercuric oxides, may be present.  Boron fluoride containing up to 5 mols. of water per mol. of fluoride is preferred.  The water, other than that present in the catalyst, and carbon monoxide may be in excess with respect to the olefine. Temperatures up to 350, e.g. 150-275 DEG  C., and pressures of, e.g. 25-900 atmos. may be used. Apparatus of acid-resisting alloys or coated with chromium or silver is preferably used.  In examples: (1) a mixture of CO, C2H4, and steam is passed in countercurrent to a liquid reaction product of hydrofluoric and orthoboric acids at 275 DEG  C. and 700 atmos. in a chamber containing active charcoal yielding propionic and other acids; (2) a mixture of CO, C3H6, steam, and dihydroxyfluoboric acid is converted into isobutyric acid; (3), (4), and (5) water-boron fluoride addition compounds are treated first with C2H4 and then CO. Heating under pressure gives a product yielding a propionic acid-boron fluoride addition compound upon distillation or yielding, upon steam distillation, aqueous propionic acid, and a residual water-boron fluoride addition compound which is recycled.  U.S.A. Specifications 1,924,763 and 1,924,766 are referred to.

Filed: 1971-06-03
Abstract: 1308273 Recording-apparatus NEW ZEALAND INVENTIONS DEVELOPMENT AUTHORITY 3 June 1971 [3 June 1970] 18869/71 Heading G1J. A cumulative quantity measuring and recording apparatus comprises a sensor to sense successive increments of the quantity by a predetermined amount, coding mechanism to register time in a binary code and a punching mechanism arranged to co-operate with the coding mechanism and the sensor in such a way that the sensor initiates a punching cycle on paper record tape and thereby automatically forms successive records in the binary code of the times registered on the coding mechanism when the sensor senses the increments. The apparatus may be a modification of apparatus designed to record quantities in code at regular intervals of time. The code discs may be driven by an electric or mechanical clock 3 through a gear chain chosen according to expected rates of variation of the quantity to ensure that a suitable time interval is represented by one division of the lowest order code disc 2. Upon the completion of each increment, a momentary contact closure or a positive going pulse turns on a latching circuit to complete a circuit including the punch motor and a battery. A double-pole double-throw relay may be used as a latch or the latching action of a silicon-controlled rectifier may be used. Among applications envisaged are tipping bucket rain gauges and solar radiation recorders. Plug-in circuit cards may be designed for ready conversion from one application to another.

Title: Improvements in or relating to fountain pen barrels and the like
IPC: B43K5/12
Filed: 1937-07-08
Abstract: Fountain-pen barrels are formed partly of transparent nitrocellulose or other ester or ether of cellulose and partly of similar but relatively opaque material arranged to form a mesh pattern, the barrel in normal aspect appearing opaque but when held up to the light being sufficiently transparent to enable the level of ink to be seen.  The mesh pattern is repeated about 8-16 times to the inch, and the transparent portions are approximately one-and-a-half to twice the width of the relatively opaque portions.  The barrel is preferably formed by compressing into a block layers of transparent and opaque material, slicing the block across the laminations, compressing the sliced layers with interposed layers of opaque material into a further block, slicing this block into layers, and finally wrapping on helically winding these layers into tubular form.
Patent GB-424042-A (GB)
Title: Improvements in making sound records photographically
IPC: G11B7/00
Filed: 1933-07-05
Abstract: 424,042. Optical sound-recording. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. July 5, 1933, No. 19081. Convention date, July 5, 1932. [Class 40 (ii)] Relates to the production of a photographic sound-record of constant width and varying density by means of a light-controlling device adapted to undergo, under the influence of the sound to be recorded, a displacement from its rest position which causes a corresponding variation in the intensity of illumination of the record surface. According to the invention, in order to compensate for distortions due to the gradation of the photographic emulsion used or to the light-controlling device, or to both, there is interposed between the light - controlling device and the record surface an optical device which causes the intensity of illumination to vary irregularly with the displacement of the light-controlling device. The Figure shows an apparatus for carrying out the invention. Light from a suitable source (shown as an illuminated slotted diaphragm a) is projected by a lens b through a slot c on to the mirror d of an oscillograph. The light reflected by the mirror forms an oscillating band g on an aperture e<1> of predetermined shape in a diaphragm e, which is arranged in front of a lens f, this lens forming on the photographic film i a stationary image h, of which the dimensions are constant, but the intensity varies in accordance with the variations in the amount of light transmitted as the band g moves across the aperture e<1>. An explanation is given, with the aid of graphs, of the manner in which the shape of the aperture e<1> is designed, using the characteristic curves of the negative and positive emulsions employed for the recording. Instead of the diaphragm e, there may be used a grey wedge with an irregularly increasing thickness ; or when using a film that is differentially sensitive to light of different wave-lengths, use may be made of a wedge which, in zones of different density, is coloured so as to be suitably absorbent for the different wave-lengths. The recording device used need not necessarily have a rectilinear characteristic, since the apertured screen e or equivalent optical device may be designed to provide the compensation required in this respect. The invention may also be applied in the production from an original record of a copy, by photo-electric means.

Filed: 1944-10-06
Abstract: 586,491. Compound sheet materials. TYCE, G. C., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 6, 1944, No. 19178. Drawings to Specification. [Class 140] [Also in Group XXVIII] Tubes or tube linings are produced by winding on a mandrel a sheet or sheets of fibrous material coated with a dispersion of finely powdered thermoplastic polymers in a non- volatile plasticizing agent such as is described in Specification 500,298, and subjecting it to sufficient heat and pressure to gelatinize the dispersion. In one example a dispersion of one part of the substance known under the Registered Trade Mark "Corvic" in one part of tricresyl phosphate is fed on to asbestos fabric, spread by a doctor knife, and wound on a polished metal mandrel with the coated side toward the mandrel. A metal band is clamped round the tube which is heated for thirty minutes at 140‹C. To facilitate separation of the tube from the mandrel the latter may be coated with grease or other suitable substance or a collapsable mandrel may be used. Metal reinforcement in the form of sheets, wire or gauze may be included in the tube. Specification 566,388, [Group IV], also is referred to.

Abstract: 1,055,853. Cooling dynamo-electric machines; slot wedges. WESTINGHOUSE ELECTRIC CORPORATION. May 7, 1965 [June 15, 1964], No. 19362/65. Heading H2A. In a dynamo-electric machine of the type described in Specification 920,558, having the rotor/stator gap divided by barriers into zones having different gas pressure, at least the lower portions of the stator barriers are formed by segments 51 having bases 52 in the form of slot wedges and spacers 53, the longitudinal assembly in each slot being held together, e.g. by an elastic member 57. The lower portions of the stator barriers 51 are arranged to be removable to enable skids to be inserted for dismounting of the rotor. A longitudinal assembly of barrier segments of glass melamine or glass epoxy 51 and spacers 53 are drawn in along each stator slot by means of glass cords 55. A polyesterimpregnated glass fibre tape 57 having a dowel 63 inserted in an end block 59, is extended sufficiently to allow a locking block 58 to be interposed between the last spacer 54 and the block 59. The tape 57 thus compresses the spacers 53 and segments 51, the ends of which are oppositely tapered so that the tensile force of the tape 57 tends to retain the bases 52 within the slot. Figs. 1, 2 (not shown) relate to the cooling arrangements comprising a liquid cooling system for the stator and a high pressure hydrogen circulation similar to that disclosed in Specification 920,558.
