Title: Improvement relating to pneumatic mechanical shoe nailing machines
IPC: A43D69/02
Filed: 1968-09-05
Abstract: 1,222,707. Shoe nailing machines. ZAVODY PRESNEHO STROJIRENSTVI NARODNI PODNIK. 5 Sept., 1968 [8 Sept., 1967], No. 42202/68. Heading B4C. In a shoe nailing machine, a last support comprises a supporting body 2 pivotally mounted on a shaft 29, a push rod 5 having an opening 25 for receiving a centring plug (15) (Fig. 2, not shown) for the last (16) and movable relative to the body by means of a pneumatically operable piston and cylinder 8, 9, an adjustable support (17) for the last mounted on an arm 20, and two mechanisms each including a unidirectional coupling, one mechanism being adapted to lock the push rod against downward movement and the other being adapted to lock the body against clockwise movement. The unidirectional coupling or clutch associated with the push rod includes a part 28 rotatably mounted on the shaft 29 and a second part 35 fixed on the shaft. A rack 26 connected to the push rod engages teeth on the part 28. When the push rod has been moved to a selected position by piston and cylinder 8, 9, a pneumatically operable piston and cylinder 48 is actuated to raise a toothed rack 45 which engages with a toothed member 44 fast on the shaft 29. Upward movement of the rack 45 causes the shaft 29 to rotate and the second part 35 to rotate and wedge rollers 36 against the part 28, thus securely locking the rod 5 against downward movement. The rack 45 may be locked in a raised position by a locking wedge 55 engaging a shoulder 56 on the rack. The wedge is mounted on the piston 54 of a pneumatic piston and cylinder device 51. The mechanism for locking the body 2 against clockwise movement includes a unidirectional coupling similar to that shown in Fig. 3. A toothed member (70<SP>1</SP>) (Fig. 4, not shown) fixed on the shaft 74 is engaged by one arm 70 of a lever 66 which is pivoted by actuation of a pneumatically operable piston and cylinder 61. The unidirectional coupling is mounted on the shaft 74 and the rotatable part has a toothing which engages with a toothed rack 78. Each coupling includes a ring with projections 39 thereon. By appropriate adjustment of a screw 42, a pin 40, fixed on the ring, is moved clockwise (Fig. 3) so as to move the ring and disengage rollers 36.

Title: Improvements in and relating to electrical signal generating devices and radio receiving equipment incorporating such devices
IPC: H04B7/08
Filed: 1964-10-19
Abstract: 1,049,366. Radio signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 19, 1964 [Nov. 22, 1963], No. 42535/64. Heading H4L. A device for providing an output signal dependent on the presence of a modulated R.F. carrier signal, comprises means for feeding the modulated signal to two or more filters designed to pass respective portions of the bandwidth of the modulated signal, means coupled to the filters and arranged to provide for each of the portions a pair of signals of opposite polarity representative of the energy content of that portion and means to select one signal from each pair and to add the selected signal to provide the output signal. A number of such devices are used at a receiving station to determine which of a plurality of carrier frequencies has been selected at a transmitter as providing the best signal so that the receiver can adapt its circuits accordingly. At the transmitting station, Fig. 1 (not shown), transmitters 21 to 24 can transmit on different carrier frequencies to corresponding receivers 31 to 34. The receivers operate at the same I.F. and their outputs are selectively connectable via a switch 46 to a demodulator 50 monitored by an indicator 52, the position of the switch being controlled by a relay 48. The outputs of the receivers are also fed to respective signal detectors 41 to 44 to determine which receiver is receiving a usable signal and to set relay 48 accordingly. A signal detector comprises three similar sections 60 to 62, Fig. 2, whose outputs are connected to a common circuit 66. Each section includes a band-pass filter 70 passing a portion of the bandwidth of the signal from the corresponding receiver, a rectifier-integrator 72 providing a signal representing the energy content of the signal passed by the filter, and a phase-inverter 76 which provides inverted or uninverted signals selectable manually by a " pass-reject " switch and fed to an adder 67 together with the signals from the other sections. If the signal from adder 67 is sufficiently great it will trigger a flip-flop 68 so that relay driver 69 will set relay 48 to connect the corresponding receiver to the demodulator 50. The " pass-reject " switch allows the detector to be set up for particular conditions such as the known presence of spurious signals on particular frequencies.

Title: Antenna-radome system
IPC: H01Q1/42
Filed: 1977-10-13
Abstract: A boresighting antenna for receiving signals within a given frequency band is covered by a radome having a wall including dielectric material. Boresight error compensation is provided by one or more pairs of perforated metal plates. Each plate has a dielectric material thereon. The plates of each pair are positioned symmetrically in relation to the longitudinal axis of the radome forward of the antenna in the radome in the direction from which the signals are received, and are tilted forward toward the radome axis from the interior wall of the radome at such an angle as to provide a phase lag in frequency components of the received signal at the high end of the given frequency band and a phase lead in frequency components of the received signal at the low end of the given frequency band. Compensation is thereby provided for the boresight error that is caused by the phase shifts of the different frequency components of the received signal that result from the received signal passing through the wall of the radome.

Abstract: 1,236,435. Hydraulic shock absorbers. A. A. DE KONING, and K. K. K. DE KONING. 11 Sept., 1968 [22 Sept., 1967]. No. 43290/68. Heading F2S. In a shock absorber of the kind in which a piston 2 reciprocates in a liquid-filled cylinder 1 communicating by way of a valve 7-10 with a surrounding annular reservoir 14, the flow path from the valve to the reservoir is by way of a crescent-shaped opening lying wholly to one side of a plane containing the axis of the piston's rod 3. The valve's body 7 is sealed to an underlying member 15 having on its upper side a central circular aperture 16 and a peripheral acruate aperture 17 and on its lower side an eccentric circular aperture 18. As best seen in Fig. 4, the crescent-shaped opening is defined by the area of overlap of the apertures 17 and 18. Within the reservoir there may be fitted a tube 19 whose cross-section matches that of the aperture 17 in the member 15 and which fits in that aperture. The base of the member 15 contains a depression 20 which co-operates with a spigot such as a bolt 21 to locate the member and, in the assembled shock absorber, provide a visible indication of the orientation of the member 15. The construction is such that when the shock absorber is installed with its axis horizontal (Fig. 5, not shown) and the crescent-shaped opening lowermost (i.e. spigot 21 uppermost), gas in the reservoir will not tend to leak into the cylinder. A conventional tube-within-a-tube shock absorber (Fig. 1, not shown) may be converted into one according to the invention by modifying its foot valve and fitting a member 15 beneath the valve.

Title: Process for the preparation of carboxylic acids
IPC: C07C51/34
Filed: 1959-12-29
Abstract: A process for preparing a carboxylic acid from an acyclic olefin or ring-containing polyolefin comprises the steps of reacting the olefin with an oxygen-ozone mixture in the presence of a reactive solvent as defined below to form an intermediate peroxide ozonolysis product, reacting the ozonolysis product with oxygen in the presence of a catalytic proportion of ozone and formic acid or mixture of formic and acetic acids, the formic acid being present in proportions of at least two mols per equivalent p  of peroxide group in the peroxidic ozonolysis product and recovering the carboxylic acid.  The reactive solvent employed is a solvent containing a C1 to C4 alkyl alcohol, formic acid, acetic acid, a mixture thereof or a mixture of one or more such solvents with a cosolvent such as acetone, chloroform or carbon tetrachloride.  Where solvents other than formic or mixtures of formic and acetic acids are employed in the ozonolysis reaction the intermediate product is recovered from the reaction mixture.  The olefinic starting materials may contain halogens or groups inert to ozone such as carboxylic acid groups, ester groups, nitro and sulphone groups.  Starting materials specified include butene-1 and -2, 1-5-hexadiene, pentene-1, straight and branched chain heptenes, octenes, decene-1, dodecene-1, cyclohexadiene, 4-vinylcyclohexene, 1,5-cyclooctadiene and 1,5,9-cyclododecatriene.  The vinylcyclohexene, cyclooctadione and cyclododecatriene may be prepared by dimer- and trimerization of butadiene.  Possible formulae for components of the peroxidic intermediates are given.  In the example heptanoic acid is obtained by passing oxygen containing ozone through a solution of 1-octene in acetic acid until 1 mol of ozone per mol of octene has been absorbed, formic acid is then added and oxidation with oxygen containing ozone is carried out at the reflux temperature.
