Title: Cooler package for electronic components
IPC: H01L23/467
Filed: 1963-03-28
Abstract: 976,053. Ventilating electronic components. INTERNATIONAL ELECTRIC RESEARCH CORPORATION. March 28, 1963 [Aug. 29, 1962], No. 12283/63. Headings H1K and H1R. A cooler package 10, Fig. 1, for transistors or other electronic components, comprises a plurality of separate individual cooler units 25, Fig. 3, joined together at their parallel end edges 28 and 29 to form a polygonal housing as in Fig. 2, with a plurality of fingers 36 and 37, extending from each unit 25 to form an enclosure for the reception of an electronic component. A plurality of polygonal housings may be connected as in Fig. 1 by strips of synthetic resin 48 connected in between the bentup edges 30 and 31 of the cooler units. Leads 47 to the electronic devices may pass into the interior of the package 10 through holes 43. The row of fingers 36 may be longer than the row 37 to increase ventilation and each row may be staggered. Air flow through the package may be natural with the package mounted on end, or may be forced, with a fan 13. Groups of fingers such as 36 and 37 may also be mounted on the outside of each unit, Fig. 6 (not shown), in which case the fan 13 may be made larger to pass air along the outside of the package as well as along the inside. If, however, a temperature difference is required between the components inside the package and those outside, the fan 13 remains as in Fig. 1. As the fingers on adjacent units of one housing are not parallel, radiation therebetween is minimized.

Abstract: 582,354. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., and KEALL, F. B. June 29, 1944, No. 12368. [Class 89 (iii)] In a fastener-inserting machine, the reciprocating driver is operated from a rotary crank through a lever to which it is coupled by a link, the movement of the lever being further controlled by a cam to impart to the driver extra speed over the major part of its movement and less speed towards the end of its movement than would be the case if the lever were omitted. The mounting of the work-feeding awl and a construction of nail separator are also described. The driver 1, guided in a throat 7, 9 on a swinging head 11, is clamped to a carrier 5 pivoted at 13 to a link 15 which is pivoted at 17 to a crank lever 19. The lever 19 is pivoted at one end 21 on a crank arm' 23 on the main shaft 25 and is provided at the other end with a cam roll 27 engaging a cam groove 29. A link 33 having a roll 45 engaging an arcuate guideway 47 on the head 11 is pivoted at 13 to the carrier 5 and at 35 to an arm 37 pivoted on the head, so as to ensure a substantially sraight-line movement of the driver. Lugs 51, 53 on the carrier 5 co-operate with faces 55, 57 on the head 11 to prevent swinging of the carrier if the driver breaks. The awl 61 is mounted on an arm 65 slidably and universally connected to a fixed bracket 67, Fig. 4, by plates 77, 79 engaging between part-ball members 75, 85. To ensure a substantially straight-line movement of the awl during work-feeding, a rod 93, 97 is provided having universal connections 91, 101 with the arm 65 and with a spindle which is eccentrically mounted in a fixed bracket 109 to allow of adjustment. Reciprocation of the awl is effected by a rock-shaft 131, Fig. 1, connected to the arm 65 through an arm 129, link 123 and ball joints 127, 121, 117. A nail separator 137, Fig. 5, is carried by a lever 135 pivoted at 139 and operated from a face cam 163 through a roll 161 on a lever 159, a two-part rod 157, a bell-crank lever 151 and a link 145 by means of universal joints. The separator 137 is moved rearwardly by the cam 16B and forwardly by a spring 169. Specifications 4471/03, [Class 89], and 350,566 are referred to.

Abstract: 721,054. Rolling. GROB, E. May 16, 1952 [May 16, 1951], No. 12502/52. Class 83 (4). In a method of forming grooves in a blank, groove.forming rollers are brought into repeated rolling engagement with the blank, the roller and blank being progressively moved relative to one another to extend the grooves. Apparatus for rolling teeth on crown wheels G comprises a rotatable carrier 11, Fig. 2, supporting rollers 10 having groove-forming ribs 17. The blank G is detachably mounted on a shaft 13 which is fed axially while continuously rotated at a synchronized speed so that the ribs 17 successively engage in partially formed grooves g. Inaccuracies resulting from the rotation of the blank G may be compensated by mounting the carrier 11 at askew angle. In further modifications a series of blanks may be arranged on a single shaft and the work may remain stationary while the carrier 11 is traversed by a carriage in a direction parallel to the grooves. More than one carrier head may be used or a number of blanks may be arranged around a carrier head so that the rolls 10 engage each blank in turn. Obliquely or helically toothed wheels may be rolled by setting the carrier 11, Fig. 4, at a skew angle and feeding the blank G either axially or parallel to the ribs 17 on the roller 10, the rate of rotation of the blank being arranged to compensate for the skew angle.

Title: Improvement in radio range and direction finder
IPC: G01S13/62
Filed: 1931-05-01
Abstract: 387,643. Wireless signalling. COMMUNICATION PATENTS, Inc., 60, Broadway, New York, U.S.A. May 1, 1931, No. 12869. Convention date, Nov. 8, 1930. Void [Published under Sect. 91 of the Acts]. '[Class 40 (v).] The distance between two points is determined by successively measuring the time of transmission of a radio signal therebetween. In one embodiment at each point is located a transmitter 5, Fig. 1a, and receiver 6 the latter being coupled to the former through the coils 10, 11. An impulse is initiated at one station by closing a key 17 and discharging a condenser 15 into the transmitter. This impulse travels to the distant point where it is received .and re-transmitted. It is then received by the initiating station and re-transmitted and so on backwards and forwards between the two stations. Each impulse is applied to frequency meters 21, 22 of low and high range respectively, the frequency of the impulses being a measure of the distance separating the stations. The meters may be calibrated in distance units. In a second embodiment, signals of controllable frequency are produced by an oscillator 50, Fig. 2a, coupled to the transmitter 35, the transmitter and receiver 36 being alternately operative under the control of an oscillator 47 preferably of higher frequency than that of the oscillator 50. A signal strength meter 44 is coupled to the coupling coils 39, 40 between the transmitter and receiver, and the frequency of the oscillator is adjusted so that upon re-transmission at the distant point, the wave will have a phase shift of either 180 or 360 and produce respectively either zero or double the reading of the meter 44. This frequency is a function of the distance and the control dial 53 of the oscillator 50 may thus be calibrated in distance units.

Title: Process for the polymerization of acetylene and apparatus therefor
Inventor: ROOT ALBERT BARNARD
IPC: C07C2/38
Filed: 1956-04-30
Abstract: Monovinylacetylene is produced by polymerizing acetylene in the presence of a liquid catalyst in a process which comprises passing humidified acetylene upwardly through a reaction column having a plurality of vertically disposed reaction zones separated by perforated plates in which the perforations represent 2-6 per cent of the plate area, the gas is fed at 10-100 p.s.i.g., the temperature of the column maintained at 60-75 DEG  C. and an acidified polymerization catalyst is passed down through the column so that the liquid, containing gas bubbles, fills 80-100 per cent of each reaction zone, and is recycled from the bottom to the top of the column.  The catalyst is preferably cuprous chloride dissolved in an aqueous solution <PICT:0793748/IV (b)/1> <PICT:0793748/IV (b)/2> of ammonium or potassium chloride with hydrochloric acid. Referring to Figs. 1 and 2 the column 1 is separated into up to 15 zones by plates 2 having perforations 13 amounting to about 3 per cent of the plate area.  Catalyst enters at 5 and flows down through downcomers 12, is separated from tarry impurities in the separator 9 and is led by lines 19 and 16 to the pump 11 which pumps it through copper turnings in the regenerator 10 and through the cooler 8 back to the inlet 5. Temperature control in the reactor is accomplished by cooling coils 14.  Acetylene, preferably containing a small amount of HCl gas, is passed in at 3 and the product is removed by line 7.  In an example a copper column 8 inches in diameter and 22 feet high is divided into 10 chambers by plates having 1/8 inch diameter holes whose centres are 5/8 inch apart and having a total area of 2.82 per cent of the plate area.  Acetylene with sufficient HCl gas to maintain 0.4-0.5 per cent by weight in the catalyst is supplied at 30 p.s.i.g. and 150-500 pounds per hour.  The catalyst contains by weight based on the solution, 31.5 per cent cuprous chloride, 25 per cent potassium chloride, and 0.4-0.5 per cent hydrogen chloride in water at 65-75 DEG  C., and is circulated at a rate of about 1 U.S. gallon per hour to give a conversion of acetylene to monovinylacetylene of 10 per cent per pass through the column and an overall yield of 88 per cent based on acetylene consumed.  Specification 401,678, [Group IV], is referred to.
