Abstract: 764,789. Sewing machines. SINGER MANUFACTURING CO. Feb. 28, 1955 [March 8, 1954], No. 5812/55. Class 112. [Also in Group XXIV] In a sewing machine the helical gears 53, 54 of the loop-taker shaft 33 and bobbin case opener shaft 38 driven from the main bedshaft by a similar gear on the latter engaging the gear 53 are lubricated by providing a lubricant retaining pad 58 in an annular recess 56 of the gear 54 and making this gear of a porous material such as a sintered metal. Oil is fed when necessary into the recess 56 through a hole 59 passing through the upper part 29<SP>1</SP> of the saddle 27 supporting the shafts 33, 38. The saddle 27 is secured to the machine bed and to a bed-shaft bearing bush in a manner which allows adjustment along the bed-shaft, together with the gear on the latter, to suit different needle spacings in a twinneedle machine having separate loop-taker units of opposite hand. The opener shaft runs at half the speed of the loop-taker shaft, and the gears 54, 53 are secured on these shafts by set-screws to allow relative adjustment of the shafts.

Filed: 1951-03-12
Abstract: 719,935. Fluid-pressure servomotor-control systems. MUIRHEAD & CO., Ltd. Feb. 20, 1952 [March 12, 1951], No. 5927/51. Class 135. [Also in Groups XXXIII and XXXV] In an automatic control system for stabilizing ships, the error signals are derived from a velocity sensitive gyroscope only so that any reaction back on to the gyroscope due to limiting the movement of the stabilizer does not affect the system. The gyroscope 1, Fig. 1, is mounted with its spindle athwartships and is free to precess about a vertical axis. The angular velocity of rolling causes a precessional torque which is converted into a proportional movement by centralizing springs. The gyroscope is coupled by a synchronous movement transmitter 2 to a similar receiver 3 which operates a hydraulic amplifier 4, 5 controlling an unspecified corrector. Movement of the receiver 3 is limited by stops 9. In a modification, Fig. 2 (not shown), the movement transmitter supplies a rectifier which energizes an electromagnetic relay controlling the hydraulic amplifier 4, 5 (above). Specification 581,776, [Group XXXV], is referred to.

A force P, Fig.1, to be measured compresses the annular laminations of a core of an element 1 reducing the air gaps between them and increasing eddy currents induced in the core thus decreasing the effective impedance of a winding 5 on the core. The winding 5 is connected in series with one section of a primary winding of a transformer 11, across an A. C. source. The core of element 1 is mounted on a partition 4 and is partially enclosed in a non-magnetic tube 7, the force being transmitted through a steel disc 9 and cushion 8 to the core. The annular laminations have a natural curvature and application of force straightens the plates reducing the air gaps. Suspended freely from the other side of the partition is an identical core and coil element 2 which is not affected by the force. The coil winding 6 of element 2 is connected in series with the other primary section of transformer 11. Thus under no load conditions the currents i 1  i 2  in the primary sections are equal and opposite and the resultant flux in the core will be zero. When force P is applied the effective impedance of coil 5 decreases and current i 1  will increase and the resultant flux in the core will produce an output voltage from the transformer secondary proportional to the load.

Title: A method for the production of new or improved films and adherent coatings containing nitrocellulose in solution in a solid polymeric resinous material, and compositions for their production
IPC: C09D101/18
Filed: 1949-03-14
Abstract: Films and adherent coatings are produced by forming (if necessary with the aid of a volatile mutual solvent), a solution containing industrial nitrocellulose and a liquid polymerizable form of an ester of a mono-ethylenically unsaturated alcohol with a mono-carboxylic aliphatic acid which contains in its molecule at least one pair of olefinic carbon to carbon linkages wherein the nearer carbon atoms of each pair are either directly linked to one another, giving a conjugated linkage structure, or are linked through not more than one intermediate carbon atom, spreading out this solution into a film on a solid substrate and, after evaporating any volatile mutual solvent used, exposing the resulting film adhering to the substrate to polymerization conditions such as to favour oxidation.  Such conditions may comprise exposure in an oxidizing atmosphere to heat or drying in an oxidizing atmosphere at ordinary temperature in the presence of a drier of the type commonly used in paints and varnishes, preferably a cobalt drier such as cobalt naphthenate.  The ester may be an allyl, methallyl or vinyl ester of sorbic, linoleic, or linolenic acid and it may be employed as such or after subjecting it to partial oxidation and polymerization by blowing air through it for a limited time at an elevated temperature.  About 0.1-1 per cent of cobalt naphthenate, reckoned on the weight of the polymerizable ester, may be employed.  Self-supporting films may be obtained by using as the substrate a glass surface from which the polymerized film may be stripped off after soaking in water. In an example quarter-second viscosity industrial nitrocellulose containing 12 per cent nitrogen is dissolved in 4 times its weight of allyl sorbate, 0.5 per cent of cobalt naphthenate (based on the weight of allyl sorbate) is added and the solution is spread out on a substrate in the form of a film which is then exposed for 1-2 hours at 80 DEG  C. In two other similar examples blown vinyl sorbate and blown allyl sorbate respectively are used, the ester in both cases being blown by passing a slow stream of air through the ester at 140-145 DEG  C. for 3.5 hours.  In a fourth example allyl linoleate is used and the nitrocellulose is dissolved with the aid of methyl ethyl ketone.  The film-forming solution may contain pigments, fillers or plasticizers, more especially such as are unpolymerizable, ester solvents for nitrocellulose, e.g. dibutyl phthalate, and other effect materials. The polymerized films are insoluble in water, alcohol and benzene. Specification 686,672 is referred to.
