Title: Improvements in and relating to a camera objective holder mount
IPC: G02B7/04
Filed: 1944-05-17
Abstract: 577,056. Lens mountings for photographic cameras. BAER, G. May 17, 1944, No. 9481. Convention date, May 17, 1943. [Classes 97 (i) and 98 (i)] An objective holder tube, slidable axially in the camera front between an operative and an inoperative position, has means for arresting it with precision against a stop defining the operative position, comprising an elastic member located in 'the holder tube (or on a camera part) and bearing against a conical surface, inclined to the optical axis at about 45 degrees, on the camera part (or the holder tube) so as to thrust the tube against the stop. The tube may be slidable in a ring insertable into the camera front by an axial thrust, there being precision arresting means of the above-described kind, both between tube and ring, and between ring and front. As shown, the holder tube 6 is slidable in a ring 4, itself slidable in a ring 1 secured in an aperture in the camera front 2. Between ring 1 and ring 4 is a single-turn spring 3 entering an annular groove 5 of rectangular section in ring 1, and bearing .against the conical side of an annular groove 5 of quadrangular section in ring 4, the pressure of the spring serving to thrust the ring axially so that a flange 4a thereon is forced against ring 1. A similar device 3a, 5a is disposed between ring 4 and tube 6, serving to thrust tube 6 axially so that a flange 6a thereon 'is forced against ring 4. The device 3, 5 serves to locate ring 4 in the camera front when the mount is inserted in ring 1, there being a conical surface 8 on ring 4 to open spring 3 as ring 4 is thrust into ring 1. The device 3a, 5a serves to locate tube 6 in operative position in ring 4. When the objective is not in use, tube 6 is thrust right home in ring 4, the conical surface of groove 5a serving to open spring 3a which then rides on the outer surface of tube 6. Springs 3a, 5a may be of rectangular or square section, the angle bearing on the conical surface being' rounded or bevelled ; or they may be replaced by radial spring pushers or balls urged radially by a spring. In a simpler, construction, the device 3, 5 is omitted, ring 4 being mounted directly in the camera front.

Title: A process for the construction or fabrication of floors and roofs without iron
IPC: E04B5/17
Filed: 1944-05-17
Abstract: 582,948. Floors and roofs. CONSTRUCTORA SACRISTAN SOC. ANON. May 17, 1944, No. 9484. Convention date, July 13, 1943. [Classes 20 (iv) and 107] A method of constructing hollow tile floors and roofs comprises placing on centering rows of hollow tiles D with other tiles E on-edge between the rows, bonding the tiles together with rich cement mortar, placing further tiles F in rows in the spaces between the on-edge tiles, each row breaking joint with the row beneath and covering the whole with a layer of concrete G. The centering, which is of a temporary nature, comprises the posts B to support the beams A which carry the parallel spaced planks C, upon which the tiles D and E are laid. All the tiles used are identical in all respects. For greater bearing strength the on-edge tiles may be laid as double rows and by spacing the rows apart and filling the space with concrete, concrete ribs may be formed in the structure. By the addition of strips of tiles to the on-edge rows and adding further layers of tiles to the rows between them, the floor depth may be increased.

IPC: B23K13/02
Filed: 1956-03-27
Abstract: 829,109. Welding by pressure. SOC. METALLURGIQUE TECHNIQUE ET COMMERCIALE. March 27, 1956 [March 31, 1955], No. 9525/56. Class 83 (4). In resistance butt-welding the opposed edges of the work, a high-frequency welding current is passed through the work longitudinally of the edges and through a series-connected conductor opposite and adjacent to the joint, the conductor serving to concentrate the current adjacent the edges to be welded. In a tube welding-machine the tube 1 is passed between two pairs of rollers 21, 25. The two conductors 20 of a high-frequency current supply of 1000- 15,000 cycles per second are connected through mercury baths 23, 26 to the rollers 21, 25. One conductor 20 has a section consisting of a bar 6 parallel and adjacent to the joint of the tube between the rollers 21, 25 and enclosed by a U-shaped magnetic assembly 11 of metal laminations which serves to concentrate the current in the tube adjacent the joint. The bar 6 may be hollow and water-cooled and the face adjacent the tube may be covered with an insulating layer. In place of the mercury baths, brushes or spring contacts engaging the rollers or the tube may be used. A wire brush for cleaning the joint before welding may be incorporated in the machine.

Title: Improvements in and relating to electric stabilising circuits
Inventor: SHAW NORMAN HARRY
IPC: G05F1/32
Filed: 1954-04-01
Abstract: 776,546. Automatic regulation. ENGLISH ELECTRIC CO., Ltd. March 25, 1955 [April 1, 1954], No. 9560/54. Class 38 (4). The D.C. voltage applied to a load 14 by a rectifier 15 supplied from a high-frequency alternator 12, is stabilized against changes in the output voltage and/or frequency of the alternator. The rectifier 15 is in series with a non-saturating inductor 16 across the secondary of a saturating transformer 10. The primary of transformer 10 is connected to the alternator 12 in series with a bridge rectifier 11 which supplies a non-saturating inductor 13. During a portion of each half cycle of input, the transformer 10 saturates and its impedance becomes small in comparison with that of the rectifier 11 and inductor 13. The current flowing in the primary circuit is then determined by the D.C. resistance of the rectifier 11 and inductor 13. This current is arranged to be greater than that at which the transformer saturates. Due to the inductance of 13, the current is maintained as a circulating current through the rectifier throughout each complete half-cycle, so that at the point in the half-cycle wherethe current from alternator 12 has fallen so that the transformer 10 is no longer saturated (and hence is providing an output to the load), the circulating current in the rectifier maintains its elements in a conducting state so that it presents very little impedance. The transformer saturates earlier if the input voltage rises and so tends to offset any rise in output voltage. A rise in the frequency of the alternator 12 tends to increase the output voltage of transformer 10 but this is offset by a rise in the impedance of inductor 16. In a modification, Fig. 2 (not shown) a threephase equivalent is disclosed.

Abstract: 1277002 Protein enriched vegetable materials W R STANTON and A J WALLBRIDGE 28 May 1969 [29 Feb 1968] 9940/68 Heading A2B [Also in Division C6] Cassava and other edible protein-deficient vegetable materials are fermented with a muceraceous fungus, e.g. of the genera Rhizopus, Mucor or Actinomucor, or a fungus of the genus Monilia, on a solid or paste-like substrate which is a mixture of the vegetable material and a compound containing nitrogen in non-proteinaceous form (specified) and assimilable by the fungus to synthesize protein, whereby the protein of the vegetable material is increased from an initial 0.01% up to as high as 10% and the level of toxicity is substantially reduced. Vegetable materials: Vegetables of the genus Manihot (particularly cassava), yam, European and sweet potato, sago, plantain fruit and sorghum. Flours of beans of the genera Glycine, Vigna, Phaseolus, Doliches or Canavalia can be added to the cassava and will then become unidentifiable in the fermented product. Lactobacilli and saccharifying enzymes are among the specified further additives for the fermentation. Micro-organisms: Rhizopus stolonifer CMI 127406 and 127407, Rhizopus Oligosporus and Rhizopus oryzae. The microorganism may be formulated with a solid nitrogen source, phosphate and magnesium stearate. A mixture of fairly coarse cassava flour with added fungi and nitrogen source is fermented in the form of an extruded spaghetti-like pasta, a lattice of short strips, modules or pellets close packed in shallow trays of expanded aluminium mesh so that the mycelial growth can develop uniformly throughout the mass of cassava and become completely interconnected. The trays are covered by a loosefitting lid of the same aluminium. The relative humidity within the vicinity of the cassava, which should be at least 85% can be maintained by a wrapping of regenerated cellulose film or banana leaves. The fermentation is terminated by drying or cooking the cheeselike product, e.g. baking, steaming or frying, or deep freezing it for storage purposes. The fermented product can also be milled to provide a protein-enriched cassava flour or added to starch-based vegetables generally. Examples are directed to the fermentation by specified fungi of the genus Rhizopus of (i) ground tubers of Manihot esculenta, (ii) steamed sorghum, (iii) ground tubers of yam, and (iv) ground fruits of the plantain Musa paradisiaca.
