Title: Improvements in or relating to induction logging apparatus
IPC: G01V3/28
Filed: 1954-02-25
Abstract: 747,889. Electric tests. SOHLUMBERGER WELL SURVEYING CORPORATION. Feb. 25, 1954 [March 2, 1953], No. 5575/54. Class 37. In a system for investigating the geological formations traversed by a bore-hole of the kind in which a unit comprising a transmitter coil 24 (Fig. 4) carrying A.C. and a receiver coil 25 is lowered into the bore hole, the pickup in coil 25 is. fed through a phase shifter 34 to the input of an amplifier 35 whose output feeds transmitting coil 24, the phase shifter 34 causing the input signal to amplifier 35 to be in phase with the output so that the system oscillates at a frequency determined by the amount of phase shift at 34, and therefore indicative of the magnetic and/or conductive properties of the surrounding media. The effect of variations in the phase shift in phase shifter 34 and amplifier 35 are eliminated by the use of a dummy coil load, e.g. a transformer 55 and cyclic switching from the main coils 24, 25 to the dummy coils 55, the resulting change in frequency being detected at 61 to record at 75 the conductivity of the surrounding formations. The coils 24, 25 may be originally fully coupled, or with no coupling, and may be duplicated as shown in Specification 678,901. In one arrangement with two receiving coils the spacing and coupling between the individual coils is arranged to give a desired degree of focusing into the wall of the bore-hole.

Title: Improvements relating to a method of mining coal or other minerals and to a conveyor-cutter assembly for use in such mining
IPC: E21C35/12
Filed: 1953-02-27
Abstract: 729,090. Endless-scraper conveyers. STAMICARBON N.V. Feb. 27, 1953 [March 1, 1952], No. 5580/53. Class 78 (1). [Also in Group XXI] In a mineral-mining, conveyer-cutter assembly in which a plough 7 slides along a guide rail 6 on the side of a conveyer 3, the depth of cut of the plough is controlled by either laterally tilting the conveyer towards or away from the mine face, or by angularly displacing'the guide rail 6 with respect to the conveyer about an axis parallel to the longitudinal axis of the conveyer, so varying the downward reaction on the plough. The tilting of the cpnveyer is due to the provision on either one of the side walls of the conveyer of a number of pairs of brackets 9, each pair being adjustably associated with supporting posts 11. The height of the wall from the floor is dependent upon the position of wedges 12 between the brackets and the posts. Alternately, said wedge-actuated support means may be replaced by telescopic posts operated by screw-adjustment means. Specifcations 729,078 and 729,079 are referred to.

Title: Improvements in and relating to fish filleting machines
IPC: A22C25/08
Filed: 1945-03-09
Abstract: 597,943. Fish-filleting machines. ATLANTIC COAST FISHERIES CO. March 9, 1945, No. 5953. Convention date, May 9, 1944. [Class 28 (ii)] In a fish-filleting machine such as described in Specification 452,688 in. which a fish tail leading and back down is fed through operating stations by side grippers, the side grippers now provided engage the fish at the tail and up to the fleshy portion of the tail. Three sets of grippers are mounted on blocks 30, carried round on conveyer chains 16, during which time the grippers are actuated by fixed cam surfaces 170, 180 and 186 successively. Figs. 4 and 11 show one set of side grippers which comprise the tail gripper 134 having an inclined row of teeth 146 and a vertical row of teeth 145 and an intermediate gripper 132, having a vertical row of teeth 145 and a body gripper 130, with three horizontal rows of teeth 140. The teeth of these rows decrease in height to conform with the shape of the fish. The teeth 140 are sharp enough to penetrate through the scales into the flesh, and on withdrawal, a spring mounted stripper plate 102 frees the teeth of adhering scales as the teeth are retracted. The stripper plate 102 also engages the fish until the teeth 140 have been retracted. All the grippers are mounted on a slide 55 in a block 30 on the conveyer chains. The grippers are actuated as described below to move oppositely disposed grippers towards and from each other. Each slide 55 comprises a spring pressed plunger 80 in a housing 60 and a second plunger 112 in a housing 56, the plunger 112 carrying one end of the stripper plate 102 the other end of which is coupled at 104 to the first plunger 80. The plunger 80 carries across key 88 slideable in slots 92 in the housing 60, the key ends also projecting in the slots 94 in the ribs of the block 30, so that when the teeth 140 are first withdrawn from the fish, the stripper remains in contact and the teeth are clear of scales &c. This stripper contacting with the fish remains until the right hand end of the slots 92 engages the key 88 and carries back the stripper plunger 80 along with the housing 60 carrying the teeth 140. When the block 30 is pulled by the chains 16 round the sprocket 12, the cam 170 bears on the rollers 74 to slide each plunger housing 60 and attached grippers towards the other to grip the fish. The roller 72 engages cam 180, which maintains the plunger housing 60 so that the stripper plates also grip the fish. The fish then passes through an undescribed fin straightener and dorsal fin remover to the belly slitting knives. Then cam 186 presses laterally on roller 72, so that the housing 60 is retracted to release the fish as above. A rail 190 acting on roller 74 maintains the slides and grippers retracted during the lower run of the chains. During this movement the roller 72 may be made to actuate the dorsal fin remover as described in Specification 591,723. Specification 466,674 for removing dorsal fins also is referred to.

The edges of the slit are inclined at f, g to take a wedge h, and the limb d may be forced away from the plate by adjusting a screw i, the maximum movement being small so that the parts spring back when the screw is loosened. For greater widths the plate is slit near both feeling edges, each slit being provided with a wedge and screw, and a wooden &c. handle is fitted to prevent errors due to temperature changes. Outside callipers connect each of a U-shaped plate with the slits near the inside edges.

IPC: C08G63/48
Filed: 1950-03-14
Abstract: In making fatty-oil-modified alkyd resins by esterifying an incompletely esterified polyhydric alcohol composition, prepared by alcoholysis of a fatty oil with one or more polyhydric alcohols and containing calcium salts dissolved therein, with phthalic acid or anhydride with or without maleic anhydride, clear, haze-free resins are obtained by adding to the polyhydric alcohol composition one or more saturated aliphatic dibasic acids of the series HOOC.(CH2)n.COOH, where n is 0 to 8, in amount at least sufficient to precipitate the calcium salts present.  The precipitate may be removed mechanically before the esterification.  The temperature of the polyhydric alcohol composition should not exceed the volatilization or decomposition temperature of the added aliphatic saturated dibasic acid at the moment of its addition.  Acids specified are oxalic, malonic, succinic, adipic and sebacic. Examples are given.

[Class 9 (i).] A sensitive percussion fuze comprising a direct-action striker b and a momentum percussion cap c in a casing a held in place by a shear wire or its equivalent is arranged at a small distance x from a fixed shoulder, constituted for example by the front end of a sleeve f, so that on discharge the wire is partly sheared and offers only a weak resistance on impact, the resistance being however sufficient to hold the fuze in place during flight. During flight, centrifugal members g move out and allow the sleeve f to be retracted by a spring f<2>, thereby leaving the fuze free to act on impact. The gap x is adjusted by screwing the front part d of the fuze body more or less into the rear part e, and clamping the parts in adjusted position by a screw i. In a modification, an additional sleeve is provided around the spring f<2> and sets back temporarily during the period of acceleration on discharge to prevent any premature outward movement of the centrifugal members g. In other modifications the shear wire secures a thimble behind the fuze a, b, c, and the fuze is covered by a cap as described in Specifications 340,810 and 370,792. Reference is also made to Specification 402,969 where the shear wire of an ordinary directimpact striker is weakened in the same way.
