Title: Improvements in and relating to means for controlling the liquid masses of tanks forcompensating the rolling of ships
IPC: B63B39/03
Filed: 1931-06-01
Abstract: 380,051. Damping rolling motion of ships. GES. FœR ELEKTRISCHE APPARATE, 44, Wilhelm V. Siemensstrasse, Marienfelde, Berlin. June 1, 1931, No. 16005. Convention date, May 30, 1930. [Class 113 (i).] In arrangements for damping the rolling motions of ships in which side tanks are alternatively pumped full and empty, a regulating- device for the pumps moves in phase with the angle of roll indicator so that feed is reversed as the ship passes through the horizontal position thus causing the liquid movement in the tanks to be displaced in phase by 90‹ so that the tank is being filled during the whole of its movement below the horizontal and is being emptied whilst above. The tanks 1, 2, either open to the sea or closed, are alternatively filled and emptied by the pressure and suction chambers 14, 15 connected by the blowing pump 17, the two-way valve 13 in the air conduit 4 effecting the desired alternation. The roll indicator 41 through the motor 40 and the gearing shown moves the controller switch arm 33 in phase over opposite contact paths 29, 30 lying in the armature current circuit of the motor controlling the cock 12 or directly driving the pump. To compensate for list the motion of the indicator 41 is fed to the screw 44 on which works a nut 45 supporting a spring-balanced hydraulic cylinder 42. Excessive one-sided movement of the cylinder is fed into the differential 37 and is then combined with the direct feed from the indicator 41.

Title: Improvements in contact banks for electromagnetic switches
IPC: H01H63/06
Filed: 1952-07-08
Abstract: 698,115. Contact-members for switches. GENERAL ELECTRIC CO., Ltd., and BENBOW, C. H. July 8, 1952, No. 16267/50. Class 38 (v) [Also in Group V] A bank of contacts suitable for telephone switches is made by locating the contacts in a row in arcuate form in a mould and injecting thermoplastic insulation into the mould so as to form a layer of inlation on one side of and between the the contacts in the row. Figs. 1 and 2 show a plate thus made, 10 being the contacts and 15 the insulation (polystyrene). The contacts may be placed in the mould separate from each other, or may be blanked from a sheet and left connected by thin fillets to form a comb which is placed in the mould, the fillets being removed after moulding. Both ends of each contact project beyond the insulation, one end being for soldering and the other for establishing contact with a switch wiper. Fig. 3 shows a contact bank made by assembling pairs of contacts between two end plates 14, 19 of mild steel. On plate 14 is laid one plate 15 with its contacts uppermost, then an insulating arc 16 of "Bakelite" (R.T.M.), then a plate 15 with its contacts lowermost, then an electrostatic screen 18 of aluminium, and so on until the required number of levels has been completed.

Title: Piezoelectric crystal apparatus
IPC: H03H9/09
Filed: 1947-06-20
Abstract: 624,257. Piezo-electric crystal mountings. WESTERN ELECTRIC CO., Inc. June 20, 1947, No. 16341. Convention date, June 5, 1940. [Class 40 (v)] A piezo-electric crystal contained within an evacuated bulb is supported solely by curvelinar conducting wires attached at one end to the crystal electrode coatings and at the other end to lead-in wires sealed into the bulb. Fig. 1 shows a crystal 27 supported within a glass bulb 21 held in a corrugated ring 62. The crystal has four deposited electrodes 31 of aluminium or silver, both major faces being divided longitudinally by etching. Along the nodal line heavier coatings, for example of baked silver paste, are applied under or over the electrodes and to these regions are connected four phosphor bronze supporting wires 51, 52, 53, 54 of diameter of about 0.004 inches. Each wire is bent twice at right angles and one end is secured to one of the lead-in wires 23, 24, 25 and 26 sealed into the "pinch," the connection to the crystal at the other end being facilitated by providing the wires with disclike heads. Excessive movement of the crystal is prevented by encircling diagonally-opposite corners with loops 55, 56 attached to wires sealed into the " pinch." The first right-angle bend in the supporting wires may be omitted, in which case the wires are L-shaped (Fig. 3, not shown). In another arrangement (Fig. 6, not shown), the wires are bent in a V-shape before approaching the crystal and in this arrangement excessive movement is prevented by mica discs supported above and below the crystal and by four U-shaped stops supported around the side edges close to the corners. Smaller crystals may be supported as shown in Fig. 4. In Fig. 7, the supporting wires 175, 176 are given three right-angle bends, though these bends may be smoothed so that the wires become S-shaped. In these cases excessive movement is prevented by inserting the ends of the crystal in slots in mica discs 181, 182 and providing stops to prevent longitudinal movement in the form 185 and 186 as shown, or as discs parallel with the slotted discs but spaced slightly from the ends of the crystal (Fig. 8, not shown). In Fig. 9, the supports comprise semicircular wires 243, 244, 245 and 246 of about 0.0142 inches diameter, from the ends of which short thinner wires connect to the crystal. The semicircular wires are inclined towards the crystal to achieve a compressional effect which tends to ensure permanency of the connection between the short wires and the crystal. The corrugated ring 254 supporting the bulb is clamped in resilient bushes 255, 256.

Abstract: 514,582. Drying systems; ornamenting. STAUDE, E. G. June 1, 1938, No. 16380. [Class 34 (ii)] [Also in Group XV] A process for applying adhesive to each of a number of articles comprises applying a water soluble adhesive in liquid form and, immediately thereafter, before drying the adhesive, a dry adhesive which mingles with the water soluble adhesive to increase the quantity of adhesive and at the same time acts as a drier. The machine shown is for gumming envelope flaps. Blanks 4 are fed from a hopper 3 by a rotary roller 2 to feed rollers 6, 7 rotating more slowly than the roller 2 to produce overlapping of the blanks. The edges of the blanks are supported by endless belts 8 with which belts 10 co-operate. The flaps pass over a roller 16 dipping in a glue reservoir 15, rotary rollers 18, 19 offset from the centre of the roller 16 serving to hold blanks with the flaps in contact with that roller. The blanks then pass over a powder-hopper 22 from which powder is thrown on to the blanks by a rotary roller 20 having pointed flutes 21. Reversely-rotating brushes 24, 25 remove excess powder which is returned to the hopper. The blanks may be fed end-to-end instead of overlapping in which case a gummer having the exact outline of the gummed part is used; also, the powder may be applied by spraying and the excess removed by suction. The powder may be gum, dextrine, flour, or a dry composition of the same material as that of'the flap-gum.
