Title: Improvements in or relating to embroidering machines
IPC: D05C11/16
Filed: 1922-01-05
Abstract: 173,776. Eberhardt, H. Dec. 9, 1921, [Convention date]. Embroidery machines.- In Heilmann type machines the threads are pulled through the work by winding them round cylinders surrounding, and rotating with, the needle clamps. The needleclamping jaws form part of a rod 4, Fig. 5, which is actuated by an angle bar 19, fixed to reciprocating supports 20. The shaft 51, Fig. 7, by which the supports 20 are reciprocated, are oscillated through a three-armed lever 53, 54, 55 from a cam disc 56 on a shaft 35. The clamping jaws 3, 7 are opened by withdrawing a key 9 in the rod 4, Fig. 5, against a spring 14. The key 9 is withdrawn by an angle bar 16, a rod 17, and a bell-crank lever 18, 23 from a bar 24; the bars 24, Fig. 4, are moved longitudinally by bars 26, and oscillating levers 31, 32 from a two way cam slot in a disc 34, Fig. 7. Switch points in the cam slot are so arranged that the roller takes each path in turn, thus opening The needle-clamps on each side of the fabric in turn. Cylinders 44, with toothed ends 45, are rotatably connected by the keys 9 to the rods 4, which are intermittently rotated by gears 58-62, from a main shaft 37, which also drives the shaft 35. As the right-hand needle clamps are withdrawn, a thread-guide rod 70, actuated by an extension 64 of the angle bar 19, descends to the position shown in Fig. 5, while another thread-guide rod 71 slowly rises and guides the thread to the surface of the rotating cylinder 44, thus pulling the thread through from the opposite clamp, which is, at the time, stationary.

[Classes 20 (i), 20 (ii) and 20 (iv)] A roof, floor or like structure comprises a plurality of girders each having a top boom 11 in the form of a longitudinally-channelled plate, a bottom boom 14 spaced away from the top boom, and bracing members 15, 16 connecting the top and bottom booms together, such girders being arranged near together so that the top booms form a substantial part of the roof, floor or like surface. The roof structure shown is of arched form and each of the girders is built up of preformed sections placed end to end to form the arch. As shown in Fig. 6, the top boom of each girder section consists of a treble channel and the lower boom 14 of a single channel, these booms being connected by welded bracing members 15, 16 of transverse and diagonal disposition to form a structure which is somewhat triangular in cross-section. The adjacent sections of each girder are connected together in position by strap plates 18 bolted on each side to the lower boom and strap plates 20 welded to the upper surfaces of the top boom. The girders are arranged close together with the small spaces between them closed by an inverted channel 21 overlapping the edges of the top booms and secured thereto by welding or bolting. Adjacent girders may be tied together by transverse angle-irons 23, 24 on the upper sides of the girders. The ends of the building consist of corrugated-metal sheeting 25 carried by posts 26 mounted on the base and secured at the top to a wall-plate 27 which is connected to the end girder. The ends of the girders are mounted on foundations 30, Fig. 3, and ties 31 below the ground level connect the opposite ends of the girders ; alternatively, the foundations may be of massive construction and designed in themselves to take the lateral thrust of the structure. The roof may be covered with soil or concrete. If desired, the bottom channel boom 14 may have its sides at right-angles to the base, in which case the lower ends of the bracing members are suitably bent to engage therewith. The spaces between adjacent girders may be closed by sheeting of plain, corrugated or channel form carried by purlins.

Title: Natural gamma radiation borehole logging system
IPC: G01V13/00
Filed: 1975-01-07
Abstract: 1466031 Borehole logging with γ rays MOBIL OIL CORP 7 Jan 1975 [15 Feb 1974] 602/75 Heading G1A A borehole logging system measures the natural gamma radiation from the bore and selects three energy bands corresponding predominantly to potassium, uranium and thorium gamma emission respectively; each of these bands is then compensated to remove the effects of the other two bands, so as to produce a measure of the potassium, uranium and thorium content of the bore. Fig. 2 shows the output of the bore probe, marked as composite, as well as the output of the probe in the presence of K, U or Th calibrating sources. Although the peaks at 1À46 and 1À76 MEV are predominantly due to K and U, it can be seen that the 1À46 peak is affected by U and Th as well, and the 1À76 peak is affected by Th as well. Thus the peaks in the composite signal at 1À46 and 1À76 need to be compensated to remove the effects of U and Th so as to produce a true measure of the K, U and Th content. In Fig. 1 the probe has a scintillator crystal 10 and photo-multiplier 11, whose output passes to three height selectors 16, 17, 18 and count rate meters 19, 20, 20. The selectors produce signals centred on 1À46, 1À76 and 2À62 MEV, so as to produce three signals corresponding to the peaks of the composite signal of Fig. 2. These signals K M , U M  and ThM are fed to a unit 22 where pre-set amounts of the signals are subtracted from one another to give signals K C , U C , Th C , representing the true K, U and Th content. Fig. 3 shows unit 22 in detail. Each input signal is buffered, at 30, 32 or 34; because the Th signal is not affected by K or U, as seen in Fig. 2, the output of buffer 30 is Th C . A fraction of The is selected at 42 for subtraction from the buffered KM signal at 35, and a fraction of Th C  is also selected at 40 for subtraction from the buffered UM at 33. This latter subtraction gives U C , a fraction of which is selected at 41 for subtraction from the buffered KM at 35. This produces K C . If the probe cystal is large it is possible for U to interfere with Th measurements, in which case a pre-set fraction of U C  is subtracted from the buffered Th M  to give Th C , Fig. 4 (not shown). Calibration: the three pre-set values in Fig. 3 are selected by initially exposing the probe to a pure Th source; the influence of Th on UM is removed by adjusting at 40 for a zero output from subtractor 33, and similarly the influence of Th on KM is removed by adjusting at 42 for a zero output from subtractor 35. Then the probe is exposed to a pure U source instead of the Th source, and adjustment is made at 41 for a zero output from subtractor 35, thus removing the influence of U on K M . The success of this calibration can be checked with a pure K source. If the extra subtractor of Fig 4. is used it is pre-set when the pure U source is used

Title: Infeed mechanism for a precision grinding machine
IPC: B24B49/16
Filed: 1961-01-06
Abstract: 912,891. Automatic load-control. CINCINNATI MILLING MACHINE CO. Jan. 6, 1961 [May 23, 1960], No. 637/61. Class 38 (4). [Also in Groups XXIII and XXIX] In an automatic control system for a rocking-wheelhead grinding machine (see Group XXIII), an hydraulic pressure-jet servo-valve controlling a servomotor feeding the wheel (see Group XXIX) is positioned in response to the variation of the load current of a grinding wheel driving motor so as to maintain the grinding pressure substantially constant. As shown, a signal representative of the grinding motor load current is derived through a current transformer, not shown, and applied across a resistor R1, Fig. 5. A reference voltage is derived from the motor supply line voltage and applied through a transformer T2 as bias to triode valves V1, V2. The voltage between the anodes of the valves is then representative, in phase and amplitude, of the deviation of the motor current from a desired value and is indicated on a meter 87 and applied through resistors R9, R10 to the input 82, 84, Fig. 6, of an amplifier comprising valves V3-V8 having outputs at terminals 92, 94 and 96, 98 energizing the solenoid windings of the pressure-jet servo-valve, controlling the servomotor feeding the grinding wheel so as to maintain the wheel motor load current constant. Potentiometers 1, 2, 5 are adjusted initially with R1 short-circuited to give equal potentials with respect to earth at terminals 82, 84. A potentiometer 4 unbalances the bridge formed by V1, V2 and the resistance charge including the potentiometers V4, V5 to produce a predetermined bias voltage which is applied to valves V3, V4 to hold the servovalve open. This bias is opposed by the load current dependent anode voltage so that at a predetermined load current, defined as a percentage of the full load current, the servovalve closes.

Title: Compositions for imparting water-repellent properties to fibrous materials
Inventor: EMBLEM HAROLD GARTER
IPC: D06M13/507
Filed: 1960-01-08
Abstract: 903,008. Waterproofing. UNILEVER Ltd. Dec. 12, 1960 [Jan. 8, 1960], No. 748/60. Class 140. Fibrous materials, particularly textiles of natural or synthetic fibres, or paper or wood, are rendered water-repellant by treatment with an aminoalkyl silicate and a wax in solution in a mutual solvent. The silicate is subsequently hydrolized by drying the material either in normally moist air, in the presence of steam, for example by steam pressing, or after immersion in water. The process may follow drycleaning or may be combined with it, in which case a vegetable, insect, or synthetic wax insoluble in the white spirit or chlorinated hydrocarbons used for drying-cleaning is employed, and the mutual solvent may be an ester such as ethyl or amyl acetate, benzene, or a methyl, ethyl, propyl or butyl ether of ethylene glycol. Ranges of concentration between 2 and 8% for both silicate and wax may be used. The silicate may be an orthosilicate of general formula Si(OR 1 )x(OR 2 ) 4-x , where R 1  is an aminoalkyl group and R 2  an alkyl group, and x is 1, 2, 3 or 4, or a polysilicate of unit formula (R 1 O) y (R 2 O) 2-y SiO where R 1  and R 2  are aminoalkyl and alkyl groups respectively and y has any value up to 2 and is preferably at least 0.1, or a mixture of such ortho- and polysilicates. The aminoalkyl groups may be derived from amino alcohols having groups R 3 , R 4 , R 5  attached to nitrogen where R 3  is a mono- or di-hydroxyalkyl group of 1-6 C atoms, R 4  and R 5  are hydrogen or alkyl or monohydroxyalkyl groups of 1-6 C atoms, and the total number of hydroxy groups in the molecule does not exceed 3, and is preferably one or two. The aminoalkyl silicates may be formed by an interchange process, whereby some of the alkyl groups of alkyl silicates are replaced by aminoalkyl groups, for example, by heating methyl- or ethyl-orthosilicate under a reflux condenser with an amino alcohol and distilling off the methyl- or ethyl-alcohol formed. Examples of amino alcohols which may be used in such a process are ethanolamine, isopropanolamine, 2-amino-butan- 1-ol and 2-amino-2-methyl-propan-1-ol. Waxes used may be vegetable waxes such as carnauba, japan, candellila, palm or ouricouri wax, solid hydrocarbons such as microcrystalline or other paraffin or ceresin wax, or soluble polyethylene, or insect waxes such as beeswax. According to the Provisional Specification, the amino alcohol used to prepare the aminoalkyl silicate may have cyclohexyl or branched or linear alkyl groups of not more than 9 C atoms, or a piperidine ring formed by the nitrogen atom and two of the alkyl groups of the amine.
