Abstract: 1,177,831. Punching. J. & S. ENGS. Ltd. 19 Jan., 1968 [23 Jan., 1967], No. 3278/67. Heading B3W. [Also in Division H2] A method of making an electrical connection between overlying portions of at least two printed conductors on respective surfaces of at least two insulating boards is described, by way of example, with reference to a single board 2 carrying printed conductors 3, 4. A punch 7 in a shroud 8 forces a metal slug 5, e.g. brass or nickel, to displace a portion of the board through an aperture 9 in a die 6, so that the upper part of the slug contacts the conductor 3 while the lower part, being of greater diameter than the aperture 9, is peened back by the die 6 to contact the conductor 4. The slug 5 and aperture 9 are preferably circular. The slug may be coated, e.g. with indium or gallium, and heated to fuse with the conductors 3, 4. Alternatively, the ends of the slug and adjacent areas of conductor may be tinned or plated and projecting parts of the slug may be flattened by rollers. In an alternative embodiment, instead of peening back the leading end of the slug 9, it is forced into a washer (20, Fig. 4, not shown), contained in the aperture 9, so that the washer contacts the conductor 4. The washer may be coated, e.g. with indium, and heated to fuse with the slug and the conductor. The upper end of the slug 5 may have an integral terminal thereon, the punch 7 being suitably modified. Reference has been directed by the Comptroller to Specification 776,373.

Abstract: 1,137,751. Magnetic recording heads. I.T.T. RESEARCH INSTITUTE. 23 Jan., 1966, No. 3328/66. Heading G5R. In a head of the cross field type, particularly for video recording and playback, flux passes across the gap 37 through the tape 11 and also normal thereto, through ferrite member 65, returning via legs (65a, 65b), Fig. 3 (not shown), and housing 60 to the lower part of core 30. Coils 42, 43 are energized with high frequency bias currents to produce fluxes which are opposed across the gap 37 and proceed normal to the tape. The windings are given an unequal number of turns so that a residual field appears across gap 37, and the number of turns may be switched, when it is intended to run the tape in the opposite direction. Coils 40 . . . 43 can be interconnected, Fig. 5 (not shown), for recording and playback. During recording, below the resonant frequency of coil 40, most of the flux from the tape passes through core portions 31a, 32a where the core gap 46 is small. Above the resonant frequency the parallel capacitance makes coil 40 operate as a shorted winding and flux is directed through core portions 31b, 32b, so that coil 41 is effective, gap 47 having a higher reluctance than gap 46. The windings 42, 43 may be connected in series aiding with coil 41 to give increased output above the resonant frequency of coil 40. The core and windings are mounted in non-magnetic metal, such as brass blocks 51, 52 in a magnetically soft material housing 60. The housing 60 is formed with a keeper surface (60a), Fig. 1 (not shown), with an aperture (60b) through which pass the pole faces, auxiliary audio cores, (300, 301) being placed on either side of the main gap. The ferrite member 65 is hinged, Figs. 3 and 4 (not shown) to allow the tape to be removed. In a modification Fig. 7, the high frequency bias winding 157 is arranged around the whole of the upper part of the head. During recording, flux threads coils 154, 155 below their resonant frequencies, and above, flux passes through core 139 so that winding 158 is effective. In a further modification, Fig. 8, (not shown), the main windings are arranged on the two core limbs only. The audio heads may be spaced from the video head, Fig. 9 (not shown).

Title: Apparatus for effecting navigational calculations
IPC: G01C21/02
Filed: 1944-02-23
Abstract: 608,846. Calculating. MATTHEWS, B. H. C. Feb. 23, 1944, No. 3390. [Class 106 (i)] Where three of the angles are known in the equation 1 - cos hour angle cos (difference co-latitude and polar distance) - cos zenith distance secant latitude the fourth angle is obtained by balancing a Wheatstone bridge. Three of the resistances are adjusted to values proportional to the known quantities and the fourth is then adjusted to balance the bridge and thus indicate the fourth angle. The resistances are provided with scales graduated in angles according to the trigonometrical function to be represented. The bridge may comprise resistances wound in drums 13, 14 and contacts 1, 2, 3, 4 carried by drums 5, 6, 7, 8 threaded for rotation on fixed screwed shafts, the pitch of the threads on the shafts and the resistance windings being the same. One end of each winding and contacts 2 and 3 are connected to a battery. Contacts 1 and 4 are connected to a galvanometer. Drums 6, 7, 8 are graduated so as to indicate latitude, declination and hour angle respectively. A graduated drum 28 threaded on the fixed shaft is coupled frictionally to drive the drum 6. The drum 5 may be locked stationary and carries a fixed index 27. The apparatus described is enclosed in a case fitted with a switch and provided with windows 40 . . . 43 through which the drums may be finger operated. Indices 32a, 22, 23, 24 on the case co-operate with the markings on the drums. To set the difference of cosines, the drums 5 and 8 are operated so that the fixed index on the drum 5 points to an angle on the drum 28 equal to the difference of latitude and declination and the index points to the zenith angle. A spiral form of resistance, Fig. 9, is provided with a hinged contact arm 4a carried by a drum 8 with an index 35 moving over a graduated drum 36 to which it is frictionally coupled. The drum used for setting the declination may in addition or alternatively to a scale of degrees have markings indicating appropriate stars or carry a scale of dates and times appropriate to the sun's declination for the current year. Four independent resistances may be used or in place of resistances other electrical devices such as condensers arranged in a suitable bridge circuit may be used.

Title: Separation of bitumen from tar sands
IPC: B07B13/00
Filed: 1974-01-24
Abstract: 1498008 Separation of bitumen from tar sand MAGNA INTERNATIONAL Inc 23 Jan 1975 [24 Jan 1974] 3395/74 Heading C5E Tar sand is mixed with water to form a slurry, the slurry is agitated and diluted with water to form a pulp having a water content at least equal to the weight of the tar sand and a temperature of at least 35‹ C., the pulp is moved primarily horizontally within a separating zone at a speed which is low enough to allow gravity settling of bitumen-free sand to form a sand bed in contact with the horizontally moving pulp but high enough to prevent permanent settling of bitumen coated sand, so that the bitumen coated sand is freed from bitumen by tumbling along the upper surface of the bed, sand is withdrawn from the bottom of the separating zone and water containing fines and bitumen is removed from the upper portion of the separating zone. Fig. 1 illustrates an apparatus in which a mixer 2 is used to form a slurry of tar sand 1 in water 3. Freed oil is skimmed from the surface of the slurry at 5 and 6 and the remaining slurry passed into a shoot 8 which discharges it between the inner stationary casing 13 (which has vanes 13a) and the upper portion of the inner rotating conical member 11 (which has vanes 19). The slurry is then rotated around the annular chamber formed between the outer casing 12 and the lower surface 15 of the cone 11 by the vanes 16 on the cone 11. The cleaned sand collects in a bed 37 at the base of the chamber and descending sand is freed from adhering bitumen by being tumbled over the surface 38 of the sand bed 37 by the swirling motion. A flow of recycled water from line 31 upwardly through the sand bed and the annular chamber removes the freed bitumen together with some adhering sand from the top of the chamber and into a collecting trough 30. Separated oil is skimmed from the trough at 35 and bitumen nodules are removed by a foraminous belt 32 through which the water passes and is recycled via line 31. The cleaned sand is continuously removed from the bed 37 by a screw auger 20. The sand/water slurry is suitably fed to the separator at 35-75‹ F.; a more complete separation of the bitumen from the sand can be achieved by mixing 10-20% (based on the weight of bitumen) of a solvent, such as kerosene or naphtha, with the tar sand prior to forming the slurry. Fig. 2 (not shown) illustrates an apparatus similar to that of Fig. 1 but in which the cleaned sand is removed by an auger located within the central shaft of the rotating conical member. Fig. 3 (not shown) illustrates an apparatus similar to that of Fig. 2 but in which the recycled water passes down through the hollow shaft of the sandremoving auger. Fig. 4 (not shown) illustrates an apparatus similar to that of Fig. 3 but in which the upper portion of the annular chamber shown in Fig. 1 is replaced by a very high turbulence slurry feed device.

Filed: 1938-02-04
Abstract: 500,911. Presses for separating liquids from solids. BAUSMAN, A. L. Feb. 4, 1938, No. 3532. Convention date, March 5, 1937. [Class 46] A series of combined pressure-plates 57 Fig. 6, and plungers 58, are loosely connected together and to a fixed head 21 arid a follower 33, forming part of a ram 28, by lost motion linkwork 43, 44. Press chambers are completed by rings 59, loosely connected together by similar linkwork 41, 42. Blocks forming the linkwork slide on rails 39, Fig. 3, attached to longitudinal tie rods 22. With the parts in the position shown in Fig. 6, material under treatment, for example cocoa liquor, is supplied through a passage 150 in the head 21 under control of a valve 151 and is distributed into the press chambers through central apertures 152 in the parts 57, 58. Filter screens or pads are secured to the outer surfaces of these parts and the parts themselves are perforated. Under the supply pressure part of the liquid in the material under treatment passes through the screens and perforations is collected in circular grooves on the inner surfaces of the parts 58 and is discharged therefrom to a receiving pan below, through radial grooves which intersect the lower portions of the circular grooves. When the chambers are filled with semi-solid material the valve 151 is closed and pressure applied to the ram 28 so that the plungers 58 are forced into the rings 59 and the cakes compressed to extract further liquid. When the ram 28 is retracted, the pressure-elements are separated by the linkwork 43,. 44. Then by means of hydraulically-operated rack and spur gearing, supported in and on the follower 33, the end link 42 is drawn to the left and the rings 59 are moved to the left over the plungers 58, so that the cakes fall freely from the chambers. Subseqnently the rings 59 are moved to the right by rack and spur gearing supported in and on the head 21 and the ram 28 is moved to the right to bring the parts 57, 58 to their original position, so that the press is again ready for charging. In the charging position the rings 59 are spaced from the plates 57 by two series of fingers 97, 97', Fig. 3, mounted on bars 98, 98<1>, which are turned hydraulically to bring the fingers in and out of their operative position. Valves for controlling the supply and exhaustion of the pressure medium to the ram 28, and the hydraulic operating apparatus are all arranged together on the side of the ram cylinder.
