Abstract: 113,093. Amigues, A. Oct. 3, 1916, [Convention date]. Sights.-Relates to sighting-telescopes and mountings therefor especially intended for machine guns, and consists of (1) a special adjustable mounting, (2) a sighting-telescope having an angularly adjustable reticule, and (3) a device for automatically adjusting the sight to correct for errors due to the heating of the barrel. In the construction shown in Figs. 1, 3, and 5, the telescope a is mounted in collars e, e' on a sight bar j, each collar being provided with a horizontal and a vertical adjusting-screw g. The sight bar j is pivoted at k to a frame l which is secured by a dovetail joint and by a spring catch v and a clamp x to a plate fixed to the gun. A coiled spring m around the pivnt k prevents back-lash. The sight bar is elevated by a screw device comprising a non-rotary screw o<1>, Fig. 5, connected to the sight bar, and a rotary screw o mounted on the frame. A casing t, Figs. 1 and 5, fixed to the screw o<1> has an opening t' through which graduations on the outside of the screw o can be seen. The reticule of the telescope is carried by an angularly adjustable ring c, Fig. 1, which can be fixed in position by a set-serew d. To compensate for the heating of the barrel, the sight can be adjusted by a screw-head g<1> or automatically by a device, shown diagrammatically in Fig. 12, comprising a metal bar A lying along the barrel and acting on a lever C, the movement of which, due to the expansion of the bar A, is communicated to the sight a by mechanism comprising a wire E, a lever G, a plunger I, a bell-crank K, and a wedge M.

Title: Improvements in and relating to steam auxiliary blower and over-grate air control gear for smoke-consuming devices, more particularly for use on locomotives
IPC: F23L7/00
Filed: 1932-01-19
Abstract: 390,280. Smoke-consuming devices. HUWYLER, O., 71, Ausstellungsstrasse, Vienna. Jan. 19, 1932, No. 1596. [Class 51 (i).] Steam auxiliary blower and overgrate air control gear for smoke-consuming devices for locomotives &c., is characterised by the provision in the auxiliary blower valve 7 of a channel 21, which permits the passage of a small quantity of steam, and which is automatically opened by the closing of the regulator and closed by the opening of the regulator, and also a channel 22, 23 permitting the passage of a larger quantity of steam, which is independent of the position of the regulator, the channel 22, 23 being controlled by the steam control valve 6. The steam control valve 6 is connected by pipes 21<1>, 22<1> to the bosses 21, 22 of the auxiliary air control valve 7, the pipe 21<1> being capable of supplying a small amount of steam to the auxiliary blower whereas the pipe 22<1> is capable of supplying a large amount. The steam control valve 6 also supplies steam from the main steam pipe 20 through pipes 24, 4 to a nozzle situated in the combustion chamber. With the lever 16, which governs the slide 32 of the steam control valve 6, in the position I, Fig. 1, the slide 32 is in the position shown in Fig. 4 and steam entering from the pipe 20 cannot pass to either of the passages 21<1>, 22<1> 24 or 27. When the lever 16 is moved to position II, the slide 32 is positioned as in Fig. 5 and steam from the pipe 20 escapes to the passages 21<1>, 24, 27. The steam in passage 21<1> can escape by way of the passages 21, 37, 23, to the auxiliary blower, only if the regulator is closed but if the regulator is open main steam will enter by way of the pipe 25, force the piston 28 and the hollow slide 36 upwardly to close the passage 37 and thus shut off steam to the auxiliary blower. When the lever 16 is moved to position III the slide 32 is positioned as in Fig. 6 and steam is opened to the channels 21<1>, 22, 23 and this is irrespective of the position of the regulator because of the reduced shank of the hollow slide 36. When the lever 16 is in position II the supply of the small quantity of steam to the auxiliary blower will thus depend on the position of the regulator, while in position III a large quantity of steam will be supplied to the auxiliary blower independent of the position of the regulator. Steam is supplied equally to the nozzle in the combustion chamber in either of positions II or III. The lever 16 must be moved from position II to position III manually but means are provided whereby the opening of the fire door will automatically move the lever from position I to position II through a system 13, 14, 15. The steam entering pipe 27 in positions II or III supplies the pressure to move upwardly a piston 42 which through a rod 17, adjustable in a longitudinal direction by separate attachable end pieces A, B or C, opens the air flap 3 by pressing on a lever 18 attached to the axle of the flap.

Patent GB-1090249-A (GB)
Title: Crosslinked acrylic acid and methacrylic acid interpolymers
IPC: C08F220/06
Filed: 1966-01-13
Abstract: Cross-linked interpolymers comprise at least 10% by weight of units of acrylic and/or methacrylic acid, 0.1-2% by weight of units of a polyallyl phosphate or phosphite of the formula <FORM:1090249/C3/1> or <FORM:1090249/C3/2> where R and R1 are each H or methyl and R2 is H or an allyl, methallyl, alkyl, aralkyl, aryl or alkaryl radical, and 0 to 89.9% by weight of units of at least one other copolymerizable monoolefinically unsaturated compound.  Examples of the latter compounds are ethacrylic, chloracrylic, maleic, fumaric, citraconic, mesaconic and glutaconic acid, amides of acrylic and methacrylic acid and their N-alkyl derivatives, styrene, ethylene, isobutylene, acrylonitrile, methacrylonitrile, alkyl acrylates and methacrylates, esters of unsaturated alcohols, vinyl pyridines, vinyl and vinylidene halides, vinyl ethers and ketones, methyl isopropenyl ketone, and dialkyl maleates and fumarates. The polymers are preferably prepared by polymerization of the appropriate monomers in an organic diluent which is a solvent for at least one of the monomers but a non-solvent for the interpolymer; polymerization can also be effected in bulk or in aqueous medium.  Suitable organic diluents are aliphatic and aromatic hydrocarbons, halogen derivatives of paraffins and benzene, aliphatic ketones, and mixtures thereof. Free-radical catalysts are generally employed, e.g. sodium, potassium or ammonium persulphate, sodium peracetate or percarbonate, caprylyl, benzoyl, pelargonyl or hydrogen peroxide, cumene hydroperoxide, di-t-butyl diperphthalate, t-butyl perbenzoate and azobisisobutyronitrile; redox and heavy metal catalysts may also be used and, also, polymerization may be induced by nuclear radiation, X-rays and U.V. radiation.  The interpolymers form gels in water and are suitable as thickening agents; the maximum effect is obtained when the polymer is neutralized, in water, e.g. with an alkali metal or ammonium hydroxide, carbonate or bicarbonate, or an amine having only one primary or secondary amino group. Examples relate to copolymers of acrylic acid with triallyl phosphate or phosphite.

Title: Improvements in or relating to teat cups for milking machines
IPC: A01J5/08
Filed: 1930-01-17
Abstract: 343,276. Cow-milkers. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. Jan. 17, 1930, No. 1726. Convention date, Jan. 19, 1929. [Class 84.] In teat cups of the kind comprising an outer rigid shell 1 and an elastic lining 2 the chamber between which is alternately subjected to suction and atmospheric pressure, the lower end of the shell, at the point where the lining is attached, is given a cross-sectional shape other than circular, so that when the pressure within the lining is equal to that in the chamber, the lining is partially flattened over the whole or the greater part of its length in a direction determined by the position at which it has been inserted in the shell. Since when the cup is dismantled for cleaning the lining will probably be reassembled in a new position relative to the shell, the lining will be flattened along a different diameter and its life thereby prolonged. In the form shown in the drawing, the ends of the shell 1 are elliptical. According to the Specification as open to inspection under Sect. 91 (3) (a) the shell may be provided with inwardly projecting central impressions or with transverse or longitudinal ribs which cause the lining to assume an elliptical shape, or the shell may be so shaped that the lining, on being compressed, becomes triangular in cross-section. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 322,889, [Class 84, Milking &c.].

Abstract: 1,080,021. Locking the wheels of a mine car. SHAW, TREW & SMITH Ltd., and D. G. SHAW. April 14, 1964 [Jan. 15, 1963], No. 1756/63. Heading B8E. The wheels 4 of a mine car are engaged and checked by levers 1 which engage in pairs upon and between each lateral pair of wheels 4. The levers 1 are pivotally carried at 6 by slides 9 which slide on shaft 11 positioned beneath the rails 3 on which the wheels 4 move. Sleeves 9 carry pins 15 which move in cam grooves 13 formed in element 12, and the latter is adapted to be pushed in the direction of the shaft 14 by a fluid cylinder. Each pair of arms 1 is connected by cross straps 5. Operation.-Shaft 14 is displaced axially so that element 12 moves in the direction towards spring 17. This movement causes, by engagement of pins 15 in diverging cam grooves 13, the slides 10 to move apart and thus to force the arms 1 in pairs away from engagement with the wheels 4 into the dotted line positions. When shaft 14 and element 12 are displaced in the opposite direction, pins 15 converge and arms 1 are moved into their wheel-engaging positions, as shown full line. Arms 1 are inclined in the vertical plane to assist their action.

Abstract: 1427886 Camera for close-range photography G L CHRISTIE 15 Jan 1974 [16 Jan 1973] 01935/74 Heading G2A A camera for close-range photography has assembled therewith a light source which can be moved towards or away from the subject through a number of indexed positions so that a constant depth of field can be maintained for any selected magnification value. As shown, the camera 2 is supported by a framework 30, 32, and its lens assembly can be adjusted axially by a knob 36 to occupy various locations 38 corresponding to different magnification values. The light source is an electronic flash device 4, and this is slidably mounted by means of a carriage 8 on a pair of rails 6, inclined at such an angle to the optical axis of the camera that the light source points directly at the subject. Mounted adjacent one of the rails 6 is a cylinder 20, rotatable about its longitudinal axis, and carrying a number of index marks 24. The focal-plane-to-subject distance, the lightsource-to-subject distance, the magnification, the aperture stop value, and the guide number of the flash source are mathematically interrelated, and the carriage 8 is aligned with a selected index mark which corresponds to the distance from the subject necessary to provide a depth of field for the particular magnification selected. Repositioning the light source 4 in alignment with a different mark 24 will have the effect of varying the intensity of the illumination at the subject while maintaining the depth of field constant, irrespective of the magnification value selected.

Title: Improvements in and relating to electric testing and measuring apparatus
IPC: G01R31/25
Filed: 1936-01-21
Abstract: 469,553. Current, pressure, and resistance measurements; calculating apparatus. WALKER, H. S., and ANSELL, W. G. Jan. 21, 1936, No. 1975. [Class 37] [Also in Group XIX] Characteristics of a thermionic valve, for example, mutual conductance, anode impedance and amplification factor are measured and recorded by means of an alternating-current bridge provided with resistances which are adjusted to give null readings, the amount of adjustment necessary being a measure of the characteristic. The bridge includes the valve 5, fixed resistance 4 and variable resistance 9, a blocking condenser 8 and input and output transformers 7, 11, the latter supplying a valve voltmeter (not shown). A small mutual inductance 17 compensates for valve capacities and stray reactances. In the circuit described, the adjusted value of resistor 9 with a null reading is proportional to the amplification factor. Anode impedance is measured by changing the bridge connections to introduce a series variable resistance in the grid circuit and a fixed resistance in the anode circuit, the resistance 9 being unaltered. The setting of the grid circuit resistance at a new null reading is then a measure of anode impedance. The mutual conductance is measured in calculating- apparatus associated with the resistor contact shafts, and is effected by multiplication, the apparatus delivering printed labels of the characteristics required. Calculating apparatus comprises type drums 24, 25 for printing the characteristics, and driven by the respective variable resistors, another drum 26 being actuated by the movements imparted to drums 24, 25 for giving a characteristic proportional to the quotient. Further drums may be provided for giving a visible indication of the readings set up. The calculating-apparatus is controlled through switch 27 which energizes magnets 29, 37 and 39 through batteries 28, 38 and 40 and contacts 32, 33, 41, 42 and 55', 56'. When contacts 32, 33 abut, disc 34 is prevented from rotating, but brake 43 is released and the dividend wheel 54 and ratchet wheel 46 are rotated proportional to one characteristic. When magnet 29 is de-energized the disc 34 can rotate and brake 43 is operated to stop the drum 24. In this condition, movement of the drum 25 in proportion to another characteristic, alters the fulcrum point 60 and at each reciprocation of the lever 62, the ratchet wheel 46 is moved to drive the dividend wheel 54 in the opposite direction to that given by the drive from drum 24. The lever 62 is connected to the type drum 26 through linkwork and, as the dividend wheel is now being driven in the reverse direction, when contacts 55<1>, 56<1> again abut, all three drums are positioned for printing the characteristics on labels fed to the platen 80.
