Title: Process for the production of filaments, films, foils and other products from aqueous cellulose solutions
IPC: D01F2/08
Filed: 1930-11-21
Abstract: In the manufacture of artificial filaments, films, foils and other products from aqueous cellulose solutions such as viscose or cuprammonia cellulose solutions, there is employed a precipitation bath consisting of an inorganic acid and the monodi, tri- or penta-hydrates of methanol or a mixture of such hydrates.  By the use of the hydrates of methanol, too rapid withdrawal of water from the coagulated product, with consequent degradation of the cellulose by the sulphuric acid or methyl hydrogen sulphate, is prevented; the filaments produced from normal ripened viscoses have a strength of above 2 grams per denier, and from viscoses prepared from unripened soda cellulose, of 3 grams or more per denier.  The sodium sulphate produced during the coagulation has a favourable action on the product; similarly other salts and additions such as magnesium or zinc sulphates, and glucose dissolved in the coagulation bath, assist the precipitation process.  The coagulation bath may be regenerated by cooling to low temperatures to cause separation of the excess of sodium sulphate together with a part of the water; and, during the coagulation process too great dilution of the bath is avoided by the addition of anhydrous methanol and sulphuric acid.  In examples, a coagulation bath for normal viscose is prepared by forming methanol dihydrate by heating together methanol and water in the requisite proportions, and adding to this sulphuric acid and magnesium sulphate; a bath for viscose prepared from unripened soda cellulose consists of a mixture of tri- and penta-hydrates of methanol prepared by mixing methanol with the appropriate quantity of water, and an addition of sulphuric acid. Specifications 21144/06, [Class 2, Acids and salts, Organic &c.], 257,924, and 257,925, [both in Class 2 (ii), Cellulose &c.], are referred to.

Title: Improvements in or relating to friction testing machines for bearings
Inventor: SPENCER WILFRED JOYCE
IPC: G01N19/02
Filed: 1955-12-07
Abstract: 800,953. Measuring friction torque. E.M.O. INSTRUMENTATION, Ltd. July 6, 1956 [Dec. 7, 1955], No. 35139/55. Class 106 (2). Apparatus for testing the frictional resistance of relative rotation between two relatively rotatable parts of a bearing or two parts of a device which are fixed to the relatively rotatable members of a bearing, includes an electric motor, the rotor 40 of which forms part of a rotor unit having a seating for the bearing or device and arranged so that one part of the bearing or device rotates with the unit, while rotation of the other part is prevented and means for varying the energization of the motor to ascertain the value required to produce or maintain relative rotation of the parts. A bearing to be tested is mounted in a housing 44, Fig. 5, fixed to an eddy current rotor 40, and the rotor is slipped over a fixed vertical spindle 43 projecting from a base 41, the spindle engaging the inner race of the bearing. The base 41 has a handle 42 and is slidable in guides 51 on a base-plate 10 shown in plan in Fig. 1, so that it can be slid into position with the rotor 40 in the gaps of two similar stators 12, 13 fixed to the base-plate and arranged to turn the rotor in opposite directions. Current is supplied to one of the stators and is increased by a potentiometer turned by a knob 32 until the disc 40 and bearing begins to rotate, the value of the current giving a measure of the " breakaway " friction. The current is then decreased until rotation of the rotor is just maintained, this giving a measure of the rolling friction. The test is then repeated using the other stator, for rotation in the opposite direction. Weights 45 can be applied to the bearing to vary the axial thrust. To remove the bearing from the housing 44 after testing a plate 46 is depressed against a spring 48 by pins inserted through holes 50 so that pins 49 on the plate eject the bearing. To quickly test whether the " breakaway " friction exceeds a certain value the knob 32 includes a presetting device whereby a spring-pressed ball on the knob enters a recess at a predetermined reading. The apparatus is calibrated by a separate rotor turned against a hair spring of known rate.

Abstract: 938,944. Covering wires &c. GEOFFROY-DELORE S.A. Sept. 29, 1961 [Sept. 29, 1960], No. 35201/61. Class 87(2). In a method for applying coverings of different colours to a wire or other elongated member in an extrusion machine, the layers are applied successively, the order of application being changed to alter the colour of the outer layer. The layers 11, 12 of the covering are applied to the wire F, continuously moving in the direction of the arrows f, through rotary valves 13, 14 and the feed. chambers 10, 9 respectively. Each rotary valve 13, 14 comprises a pair of channels 15, 16 and 17, 18, respectively, arranged so that each of the coaxial extrusion screws 3, 4 may deliver material to one of two chambers 10, 9 while being isolated from the other. In the position shown the extrusion screw 3 feeds material to the chamber 10 for the outer layer 11 by means of the channel 15 and valve 13, but cannot feed any material into the chambers 9. When the valve 13 is rotated the screw 3 feeds material into the chambers 9 for the inner layer 12 by means of the channel 16. The valves 13, 14 are connected so they may be rotated simultaneously, and the length of the channels connecting the screws 3, 4 to the chambers 9, 10 are substantially equivalent.

Title: Single-lens reflex cameras
IPC: G03B7/099
Filed: 1972-07-24
Abstract: 1336536 Reflex cameras ASAHI KOGAKU KOGYO K K 24 July 1972 [9 Aug 1971] 34524/72 Heading G2A A single lens reflex camera has a viewfinder 4, a reflex viewing mirror 2, a photo-sensitive element 6 positioned in the viewfinder to receive light from an objective 1, and a retractable light intercepting member 7 placeable in the light path between the mirror and the viewfinder. During viewing, the photo-sensitive element measures the light intensity Bo incident through the objective and is electrically stored to control a subsequent shutter exposure time. In addition, reversely incident light Be is reflected within pentaprism 4 and gives an additional input to the element 6. The light intercepting member 7 is provided so that after the mirror has swung up the amount of the additional input stays constant and is not increased by additional reflections from the mirror. The electronic circuit coupled to element 6 is thus provided with a signal corresponding to the amount of the additional input and produces a corrested signal corresponding only to Bo to provide the subsequent shutter control.
Patent GB-355288-A (GB)
Abstract: 355,288. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Brand, S. ; 144, Forrer Boulevard, Oakwood Village, Dayton, Ohio, U.S.A.) May 21, 1930, No. 15602. Convention date. May 22, 1929. Addition to 250,612, [Class 106 (i), Calculating &c.]. [Class 106 (i).] Adapted for multiple-item transactions.-In the machine of the parent Specification the clerks' keys are locked throughout a multiple-item entering operation and are released only at the end of the total-taking operation. Depression of a clerk's key 30 rocks, through a detent bar, a dog 43 to free the beak 198 of an arm 199 loose on the release shaft 196. Fast on this shaft is a collar 202 provided with a nose 201 normally engaging a stud 200 on the arm 199, the stud and nose being pressed into contact by a spring 203. The release shaft having been freed and rocked clockwise, a shoulder 228 on the arm is seized by a latch 225 which therefore holds the arm in displaced position, locking the key-detent bar 36 against movement, by co-operation of a shoulder 221 on the arm with the end 222 of the bar. These parts retain their position until, at the end of the total-taking operation, a hook 235 on a slide 236 rocks the latch clockwise to permit the arm 199 to return to normal position with its stud 200 abutting the nose 201. The slide 236 is controlled by the shaft 55, rocked differentially according to whether a single-item key or a multiple-item key is depressed. In single-item transactions the slide is shifted fully to the left and the latch is therefore disabled. The actual release of the clerk's keys is brought about by a stud 57 on the voucher-feed sector 46 wiping past a lever 59, the upper end of which meets a stud 62 on, and so displaces, the detent bar 36. In a total-taking operation terminating a multiple-item transaction it is necessary to delay the release of the latch as otherwise it would reengage the shoulder 228 and for this purpose the mechanism shown in Fig. 3 is devised. The lever 178 fast on the control shaft 55 has a pin 179 adapted to be seized by the end 185 of a pitman 186 reciprocated by cams 189, 190 on the main shaft 79, one of the cams acting through a yielding abutment lever 193. The cams are so timed that the lever 178 and therefore the slide 236 are held in their displaced positions until the release shaft 196 and the arm 199 have returned to normal position. Specifications 227,861 and 248,763, [both in Class 106 (i), Calculating &c.], are referred to.

Title: Improvements in or relating to automatic brake adjusting mechanism
IPC: F16D65/54
Filed: 1929-11-21
Abstract: 343,571. Compensating for wear in brakes. MARYON, H., 18, The Grove, Ealing, London. Nov. 21, 1929, No. 35702. [Class 103 (i).] A device adapted to form part or the whole of a transmission rod or cable between a brake lever and a brake shoe or shoes and of the type in which the effective length of the device is automatically shortened to reduce brake clearance comprises a toothed bar 1, Fig. 1, secured to the driven part 3 of the transmission element and having two separate sets of teeth 1a, 1b, the teeth 1b being undercut, a movable casing 2 connected to the driving part 4 of the transmission element and carrying spring-pressed driving pawls 2a to engage the teeth 1a, and a fixed casing 5 carrying spring-pressed pawls 5a for engaging the teeth 1b in order to take up excessive brake-shoe clearance and, by the undercut nature of the teeth, to provide the necessary small clearance when the brakes are released. In operation as the brake lining wears, the travel of the rod 1 to the left in Fig. 1, when applying the brakes, increases until the pawls 5a are each able to take up another tooth 1b while on the return movement the pawls 2a engage with the next pair of teeth 1a. In a modification, the fixed casing 5, Fig. 1, is replaced by a casing 5, Figs. 3, 4, connected by springs 10 to the casing 2 and having a limited longitudinal movement giving, on the release of the brakes and the return movement of the casing, the necessary small clearance corresponding to that given by the undercut teeth 1b. This movement of the casing 5 is limited by lugs 14, 15 sliding on a rod 16 and abutting respectively a fixed joint 17 and a pin inserted in one of a series of holes 19 in the rod 16. For preventing the pawls 5a from taking up more than one tooth at a time and also to serve as an emergency transmission means should the pawls 2a cease to function, a stud 13 fixed to the casing 5 is adapted to slide in a slotted plate 11 secured to the casing 2. The pawls 2a, 5a in this case are alike and the bar 1 has one continuous set of teeth 1ab. When applying the brakes the casing 2 will move the bar 1 to the left by means of the pawls 2a and also the casing 5 by means of the springs 10. If clearance is excessive, the movement of the casing will be prevented eventually by the lug 15, and the casing 2 and bar 1 will keep moving to the left until the pawls 5a take up another tooth. On release of the brakes the casing 5 and bar 1 will move to the right until the casing is stopped by the lug 14 engaging the joint 17 and the casing 2 will be pulled back by the springs 10 into its former position relatively to the casing 5. Teeth may be provided on one side only of the bar 1 together with one pawl 2a and one pawl 5a. In both constructions the casings 2, 5 have a removable cover 6 and a bottom plate.
