Title: Improvements in or relating to Magnetic Tape Recording and/or Playback Apparatus
IPC: G11B15/18
Filed: 1966-09-22
Abstract: 1,165,981. Magnetic recording and playback. MINNESOTA MINING & MFG. CO. 22 Sept., 1966 [23 Sept., 1965], No. 42408/66. Heading G5R. A tape cartridge 15 for supplying a magnetic tape 38 to a recording and/or playback apparatus 16 which has a reel drive spindle 84, comprises a container 17 formed of shells 19, 21, Fig. 4, enclosing a pair of reels 22, 23 arranged coaxially one above the other to rotate on sleeves 27, 32 formed integrally with clutch discs 26, 30 and connected to each other by a projection 34. Clutch disc 26 is formed with tabs 33 to provide a drive coupling with reel driving spindle 84. Each reel 22, 23 has a flange 25 provided with a friction pad 31 to co-operate with the clutch discs. The tape 38 extends from upper reel 22 around a guide pulley 39 across a cut-away portion 20 of container 17, between upper tines of a tape guide assembly 47 and to a guide pulley 41. In traversing guide pulley 41 the tape is twined 180 degrees and retwined from the lower side of the pulley 41 between the lower tines of tape guide assembly 47 and across the cut-away portion 20 of the container to a guide pulley 42, Fig. 15, mounted on the same support pin 36 as pulley 39. Cartridge 15 is placed on a support deck 65 of reproducing apparatus 16. A capstan 83 extends from the deck 65 and is so positioned that the tape passes along one side of the capstan in two axially spaced positions. A reel driving spindle 84 is driven in a single direction by a motor 77 which also drives the capstan. Pressure rollers 201, 202 are movable selectively towards and away from the capstan to move the tape first in one direction and then in the other after a predetermined amount of tape sensed by an arm 176 has been withdrawn from a given reel 22 or 23. A cam 200 is provided to position the appropriate pressure roller 201, 202 and to alter the vertical position of a magnetic head 70 so that it will be in a position adjacent a different track on the tape in the new direction of tape travel. A retractable tape guide pin 131 is provided to disengage the tape from head 70 whilst these adjustments are taking place. The volume of the signals applied to or received from the tape is amplified by an amplifier (237), Fig. 16 (not shown) which is adjustable by a control knob 116 which meshes with a gear sector 114 on an arm 90 the movement of which is controlled by a timing mechanism 91, Fig. 6. The cartridge 15 is provided with a brake (58), Fig. 2 (not shown) to retain the tape on the reels when the cartridge is not in operative position.

As shown Fig. 1 a transistor oscillator 12 has an LC circuit 16 and a feedback capacitor 14 between the collector and emitter. The "hot" plate 18 of the sensor capacitor is connected through capacitor 22 to the base/emitter circuit and the other sensor plate 20 (or 20 and 24) to the earth line. Rectifier 44 converts the oscillator output to D.C. for application to the trigger/relay circuit Fig. 2 (not shown).

Title: Improvements in or relating to electromagnetic methods of and apparatus for prospecting the earth's subsurface structure
IPC: G01V3/08
Filed: 1962-11-09
Abstract: 985, 500. Prospecting electromagnetically. COMPAGNIE GENERALE DE GEOPHYSIQUE. Nov. 9, 1962 [Nov. 10, 1961], No. 42531/62. Drawings to Specification. Heading G1N. A method and apparatus for prospecting electromagnetically the sub-surface structure of the earth for an electrically conductive deposit, employs a primary magnetic field rotating about a vertical axis at an angular velocity corresponding to an audio frequency and an arrangement for detecting at a remote point a fixed-direction component of the composite magnetic field resulting from the primary field and eddy currents in the deposit, a sub-component of the composite component in phase quadrature with a further subcomponent which is itself in phase with the fixeddirection component of the primary field at the receiving station being isolated to indicate the presence of such a deposit. The rotating field may be produced by rotating a D.C. energised coil, rotating a magnet, or by supplying two perpendicular coils with A.C. in phase quadrature; and correct phasing at the receiver may be achieved by a high frequency radio beam rotating in correspondence with the magnetic field. One transmitter may be used with a number of receivers. The apparatus described responds to the vertical field at the detection point but the use of the horizontal or other directions is envisaged. A mathematical analysis is included.

If single-fold oil is used 10 parts of oil, 2-4 parts of glycol, and 30-40 parts of solvent are used. The solvent may be hexane, heptane or petroleum ether. The flavouring is used in the preparation of lime, grapefruit, lemon or tangerine flavourings. The extraction is carried out at or slightly below ambient temperature.

Abstract: 1,267,550. Making boxes. GENERAL NAILING MACHINE CORP. 27 Aug., 1969 [5 Sept., 1968], No. 42759/69. Heading BSD. A carton having a base panel 46, Fig. 9, and two side panels 47, 48 hinged thereto has the two remaining sides formed of separate end panels secured to the panels 46, 47, 48 by glue flaps 46f, 47f, 48f. The panels are assembled by a plunger and die, the plunger moving horizontally. The blanks comprising the panels 46, 47, 48 are stacked vertically in a magazine above the plunger 78 and die 79, teeth 41 on a finger 39 feed each blank to rolls 44, 45 that pass the blank down to a position between the plunger and die. Flaps 46f, 47f, and 48f pass a glue applying roller as they move downwardly. The separate end panels 105, Fig. 9, are fed from two magazines, one on each side of the die and plunger. As each blank is fed downwardly it trips a plate 166 and withdraws a catch 175 so that the plunger is free to move into the die. As the plunger moves into the die, panels 46, 47, 48 are folded to U-shape and pickoff plates 107 on the trailing end of the plunger feeds an end panel 105 into each open end of the U-shaped panels 46, 47, 48. Members 110, 111 assisting initial folding of panels 47, 48 and deflectors 181 fold flaps 46f. Presser plates 119 are moved towards the folded blank and end panels and press the carton on to the plunger until the glue has set. A rock shaft 115 moves the plates 119. Movement of the plates 119, of the plunger into the die, and the feed of the blank comprising panels 46, 47, 48 are controlled by linkages from cams on a shaft 98 driven from an electric motor and by chain and sprocket gearing. An adjustable time delay is included in the electric control circuit. A quick setting hot glue is used to enable the machine to operate at high speed. If the output is to be reduced it is not feasible to run the machine more slowly since this would necessitate changing to a slower-setting glue. This problem is overcome by running the machine at its usual high speed but interrupting the cycle for a predetermined period of time. Springs 184 press on the top and bottom sides of a formed carton to bow those sides inwardly, the carton being ejected as the next blank is folded in the die and engages the inwardly bowed sides.

Abstract: 1276194 Infrared gas analyzer MINE SAFETY APPLIANCES CO 29 Aug 1969 [9 Oct 1968] 43184/69 Heading G1A An infrared analyzer of the type disclosed in Specification No. 1173415 has its circuitry modified so that the analyzer may operate in an unbalanced condition, i.e. with the respective light beams entering the two cells 7 and 14 being of different energy. This energy difference may be obtained using an adjustable shutter 31, by running the source 2 on lower power than source 1, or by dispensing with source 2 and reference cell 14 entirely. The thermistor 23 is made one arm of a bridge circuit whose AC output is first amplified, then rectified, and finally smoothed before display on a meter 41. In use, firstly, flow equilibrium through flow chamber 22 is achieved in the absence from cell 7 of the gas component to be measured i.e. heat-induced flow into chamber 16 during radiation pulses is equal to the reverse pressureinduced flow between pulses. Then potentiometer 42 is adjusted to give a zero reading on the meter. Finally, the gaseous component is introduced into the sample cell and the. new meter reading gives an indication of the absorption of this component.
