Patent GB-900643-A (GB)
Title: Improvements in or relating to an adhesive splicing device
IPC: G03D15/04
Filed: 1958-07-25
Abstract: 900,643. Laminates; film splicers. KODAK Ltd. July 25, 1958 [July 31, 1957], No. 23971/58. Classes 31 (1) and 140. [Also in Group XX] The abutting ends of two strips are joined by means of an adhesive patch transferred to one or each face of the strips from an applicator on which the patches are adhesively carried until used. As shown, handle 8 is brought down so that knife 9 cuts the over-lapping ends of film strips 11 and 12 to provide an interlocking arrangement of their abutting end edges. The film is removed from projections 14 and, after removing a non-sticking paper separator from between the flaps 17, 18 to expose the high-tack adhesive surfaces of patches 19, the lower flap 18 of an applicator is located on bosses 25, 26 and the two central projections 14 with the adhesive surface of the lower patch 19 (not shown) facing upwardly. On replacing the film and pressing down the flap 17 the patches 19 are stuck on the film. The applicator is formed from a web of heavy paper or cardboard stock by first coating two areas with low tack pressure-sensitive adhesive and attaching adhesive patches 19 to these areas with their high tack adhesive coated surfaces facing outwardly. Before the web is folded down a central line, a separator 28 of paper to which the adhesive of patches 19 will not readily adhere is inserted and apertures 21 and 22 cut out to trim patches 19 as the applicator is severed from the folded web. Perforations 27 are also formed in this single cutting action and, together with apertures 22, are used for locating the applicator with respect to the film to be joined. Patches 19 are of thin transparent material such as polyethylene terephthalate and the adhesive effect of the low tack adhesive may be reduced by embossing flaps 17, 18 of the applicator.
Patent GB-749976-A (GB)
Title: Improvements in or relating to automatic paralleling control for a pair of alternators
IPC: H02J3/42
Filed: 1954-08-18
Abstract: 749,976. Automatic paralleling systems for alternators. SUNDSTRAND MACHINE TOOL CO. Aug. 18, 1954 [May 27, 1954], No. 24021/54. Class 38 (4). Automatic operation of a circuit-breaker 40, 41, for paralleling the incoming machine B with a running machine A at a favourable point in the slip cycle when their speeds are substantially in synchronism, is effected by a condenser 23 which is charged over rectifier 27 and contacts 21, 28 of a relay 20 during part of the slip cycle and subsequently discharged over relay contacts 21, 29 into the winding of a further relay 31 having contacts 34, 38 which control the energizing circuit of the circuitbreaker coil 40. Closure of a manual initiating switch 1 applies the beat voltage between corresponding phases A1, B1 of the two machines (suitably reduced by resistor 9) to the relay winding 20 over a rectifier bridge 12, so that the relay pulls in when the beat voltage reaches a certain value, remains closed for a time dependent upon the frequency difference between the machines and then drops out when the beat voltage falls to some lower value towards the end of the beat cycle when the machines approach phase correspondence. The cycle then repeats. The time constant of the charging circuit of condenser 23 is such that the condenser can only acquire sufficient charge to actuate relay 31 when the speeds of the two machines are substantially equal. The combined operating times of the relay 31 and circuitbreaker 40, 41 is preferably matched to the time required for the beat voltage to fall from the drop-out voltage of relay 20 to zero. The circuit-breaker is of the mechanical latch-in type.

IPC: F16D65/48
Filed: 1954-08-21
Abstract: 760,373. Internal shoe-drum brakes. GIRLING, Ltd. Aug. 12, 1955 [Aug. 21, 1954], No. 24401/54. Class 103 (1). In a manually-operated adjusting device for internal shoe-drum brakes the adjuster cam is integral with, or is carried by, a spindle which extends through an opening in the back-plate of the brake and a blade or plate-spring keyed on the spindle has one or more radial teeth for co-operating resiliently with a radially grooved or serrated plate or disc keyed to the back-plate so that the spindle is effectively located in any angular position in which it is set. In the embodiment illustrated in Figs. 1 and 2, a snail cam 11 co-operates with a peg 12 on a brake shoe 13 for adjusting the " off " position of the shoe. The cam 11 is mounted on the inner end of a spindle 14 which extends through the fixed back-plate 10 and the outer end being formed with a square section to enable the spindle to be moved angularly by a spanner or the like. The spindle is held in any angular position in which it is set by the engagement of a spring 20 having teeth 21 which engage the serrations 17 on a fixed dished disc 16 keyed to back-plate 10. A distance-piece 22 is provided between the cam 11 and the spring 20 to keep the spring 20 in engagement with the dished disc 16. The two teeth 21 are not diametrically opposed, one being off-set angularly by an angle equal to half the angular spacing of the serrations, so that adjustment of the cam can be effected in angular steps equal to half the spacing of the serrations for fine adjustment. Fig. 7 illustrates a further embodiment in which the adjuster forms an anchorage and adjuster for the ends of both brake shoes remote from the actuator, the cam surface being formed by the base of the groove 26. On the outer end of the cylindrical member 27 is a reduced axial extension 28 which projects through the back-plate and a disc 31 and spring 32, of the same form as that described in connection with the first embodiment, are mounted on the extension 28 outside the back-plate 29.

Filed: 1968-05-22
Abstract: 1,218,220. Echo sounding transducer. SIMONSEN & MUSTAD A.S. 22 May, 1968 [31 May, 1967], No. 24454/68. Heading H4J. An echo sounding transducer 6 (Fig. 2), e.g. for sea fishing, comprises two vibratable surfaces 2, 3 each having a width of 0À7 to 1À3 wavelengths in water at the frequency of acoustic energy transmitted by the transducer 6. The two surfaces 2, 3 are disposed side-by-side with their lengths substantially parallel and with a space of width 0À1 to 0À4 wavelengths in water at such frequency between the adjacent sides of the two surfaces. The surfaces 2, 3 are preferably made up of laminations and are energized by supplying an alternating current to a common winding 5. The polar diagram of the transducer 6 (Fig. 3, not shown) has relatively large side lobes so that useful information from a region extending to 30 to 40 degrees on each side of the axis of the main lobe is obtained. Information about the configuration of the sea bottom in regions to the side of the main lobe is thereby obtained. Preferably the transducer 6 is combined with a further transducer 1 (Fig. 4) comprising a single retractable surface, the polar diagram of which has negligible side lobes. The two transducers 6, 1 may be vibrated simultaneously or at different times and in phase or out of phase. As shown (Fig. 4), the transducer 6 has laminations perpendicular to the laminations of transducer 1 so that their polar diagrams are perpendicular. The transducer 1 may be rotated by 90 degrees (as compared with Fig. 4) so that the polar diagrams are coplanar. Alternatively transducer 6 is rotated by 90 degrees so that the polar diagrams are in parallel planes.
