Title: Improvements in wrenches
IPC: B25B13/50
Filed: 1924-07-22
Abstract: 229,567. Moore, F. April 22, 1924, [Convention date]. Sliding and pivoted jaw wrenches; jaw faces.- In a pipe &c. wrench having a rotatable toothed inner jaw, means are provided to limit the extent of penetration of the teeth into the pipe &c. to be turned. The jaw 11 is mounted between the cheeks 9 of a sleeve 8 slidable on the shank 2 carrying the fixed jaw 6, the cheeks thus forming a guard to prevent undue penetration of the teeth into the pipe &c. Pinions 13, integral with or fixed to opposite sides of the jaw 11, engage racks 5 on the shank 2 so that as the pipe is turned the pinions act to press the jaw into firmer contact with the pipe. The shank 2 is preferably formed by bending a sheet metal blank to form a handle portion 3 of oval section, the remainder being of U-section in which the fixed jaw 6 is secured by a pin 7 and by welding or brazing. A spring 14, acting upon an arm 17 of a follower 18 secured to the sleeve 8, normally presses the jaw 11 towards the jaw 6. The spring is mounted on a rod 15 connected to a cross pin 16 and passing through a hole in the arm 17.

Title: Noise-excited resonance apparatus
IPC: G01R33/46
Filed: 1971-05-27
Abstract: 1344084 Radio frequency resonance spectrometers VARIAN ASSOCIATES 27 May 1971 [28 May 1970] 17590/71 Heading G1N In a radio frequency resonance spectrometer, the sample is irradiated with radio frequency energy, the R. F. being amplitude- or phasemodulated, or the polarizing field amplitude modulated, in accordance with a random or pseudorandom (i.e. repetitive) sequence to excite simultaneously a plurality of resonance lines in the sample, and the resulting resonance signal is phase detected and analysed by a method involving correlating the detected resonance signal V(t) with a sample of the random or pseudorandom sequence S(t) preceded or followed by Fourier transformation. In Fig.1, the sample is disposed in a polarizing field Ho and the phase of the R. F. is modulated at 4 by 180 degrees phase shifts at intervals determined by a random or pseudorandom sequence generator 5. The correlation is performed at 11 by a multi-channel circuit Fig.2 (not shown). Each channel consists of a multiplier (18, 25, &c) and integrator (19). Either of the signals V(t) and S(t) is fed directly to all the multipliers and the other signal is fed via delays (24, 26, &c). If a pseudorandom sequence is used, a time average computer may be interposed between amplifier 9 and correlation unit 11. In an alternative spectrometer Fig.4 (not shown) S(t) and V(t) are Fourier transformed by respective units (37, 38) before multiplication. If pseudorandom noise is used, a multi-channel storage and adder may be used to accumulate a time average of the noise-excited response (between 9 and 38) or to accumulate a time average of the spectrum (between 39 and 14). The Fourier transformations and multiplication may be performed in a digital computer Figs.5 and 6 (not shown) and automatic field-frequency control may be provided. In either spectrometer, field modulation may be used instead of phase modulation of the R. F. Fig.3 (not shown) the amplitude and duration of the modulation pulses being such as to cause a 180 degrees phase reversal of the gyromagnetic moments in the sample. The spectrometer may be a nuclear magnetic resonance, electron spin resonance, or nuclear quadrupole resonance spectrometer.

Title: The manufacture of conversion products of higher paraffin hydrocarbons
IPC: C07C17/00
Filed: 1931-02-06
Abstract: In the process of the parent Specifications, according to which products stated to be lubricants for use in the textile industry are obtained by treating halogenated technical mixtures of higher paraffins with aqueous caustic alkalies, alkali carbonates or alkaline earths, halogenated technical mixtures of paraffins are employed which contain at least nine halogen atoms and at least nine carbon atoms in the average molecule.  The products contain substantially less halogen than the starting materials.  In an example, a chlorinated product obtained by treating hard paraffin until the entrance of 14,5 chlorine atoms into the molecule (average molecular weight 367) is boiled under reflux with aqueous caustic soda.  The product is an elastic mass which may be purified by redissolving in a solvent, e.g. carbon tetrachloride, and is entirely saturated.  By heating the same starting material in an autoclave with excess of milk of lime, an unsaturated product is obtained which on exposure in the warm in a thin layer, yields a lustrous elastic film.ALSO:In the process of the parent Specifications according to which halogenated technical mixtures of higher paraffins containing more than eight carbon atoms and at least two halogen atoms are treated with aqueous caustic alkalis, alkali carbonates or alkaline earths, halogenated technical mixtures of paraffins are employed which contain at least nine halogen atoms in the average molecule.

Filed: 1951-08-03
Abstract: 709,224. Measuring hardness photo-electrically. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 7, 1952 [Aug. 3, 1951; Nov. 7, 1951], Nos. 18408/51 and 26052/51. Class 40 (3) Apparatus for measuring the hardness of a surface comprises a rocking pendulum consisting of two identical flat rings 1 (Fig. 1), connected together by spacer bars 2 and having an eccentric weight 4, which is set rocking with a known initial amplitude, and photo-electric apparatus for counting the number of swings before the amplitude of oscillation falls below a predetermined level. The pendulum is mounted on the test surface 6 (Fig. II), and tilted until a particular, ferromagnetic, spacer bar 14 is located in the grooved polepieces of an electromagnet 12, and its release initiates the rocking motion with a fixed initial amplitude. Part of the surface between the rings 1 of the pendulum is covered with a shield 5, having a horizontal lower edge, which interrupts a beam of light from a lamp 8 to a photo-cell 10 for only part of each cycle, until the amplitude of oscillation is reduced to the predetermined level, when the beam is completely cut off from the photo-cell. The latter feeds into an amplifier and counting device which records the number of changes in light level reaching the photo-cell, i.e. the number of swings. In modifications, the shield 5 may be located to normally pass light to the cell 10, or the part 5 may have an externally reflecting surface, when the photo-cell and lamp are located on the same side of the pendulum, or a refracting prism may be used. The mirror 5 may be small, giving two impulses from the photo-cell for each complete swing, only one of which is counted.
