Title: Improvements in or relating to apparatus for measuring ships' speed and/or mileage
IPC: G01P5/06
Filed: 1942-10-08
Abstract: 560,767. Ships' logs. PETROFF, A., and IMPROVED SUBMERGED LOG CO.., Ltd. Oct. 8, 1942, No. 14156. [Class 97 (ii)] In a ship's log of the kind described in Specification 425,160, there is provided in a streamlined extension a<6> of the stream-lined chamber b a cavity 3 containing a bellows chamber 4, the outer surface of which is in direct communication through openings 5 with the water in the vicinity of the impeller. The interior of the bellows chamber 4 is open to the space in the chamber b and both these chambers are completely oilfilled. In operation, if there are no air bubbles present in the oil, then no matter what depth, say, a submarine dives, there will be no tendency for water to enter by way of the oil-filled gland of the impeller shaft. If air bubbles are present, then, under the conditions of a deep dive, although the static pressure in the vicinity of the impeller would greatly increase, there would be no tendency for the oil in the gland to be forced inwardly, since the internal pressure communicated to the oil by way of the bellows chamber would automatically increase in proportion to the depth of dive. Specification 437,829 also is referred to.

Abstract: 1387157 Making truss members; flanging and corrugating; welding by pressure; severing C-O Inc 28 March 1972 [29 March 1971] 14367/72 Headings B3A B3E B3R and B3D A method of making truss members comprises intermittently moving a pair of flat channel forming strips S, Fig. 3, and a flat strut forming strip T, Fig. 7, through a forming station, simultaneously pressing the strips S, T to form oppositely disposed channel members 10, Fig. 1, and to shape the strut forming strip into a pair of oppositely shaped struts 12, each of which has flat end portions 13 and a generally U-shaped intermediate portion 14, bending the flat end strut portion with respect to the remainder of the strip portion to provide alternating extending apices 15, moving the channel members and struts to a welding station and welding the apices to the channel members. The strips S, T are fed from respective rolls 50 (161), Fig. 5 (not shown), and pressed in a press 51 having opposed dies 52, 53 and a floating die 54. The dies include portions 60, 61 for shaping the strip 7 to form the strut members and single operation of a fluid ram 162 allows the press to simultaneously form the channels and struts. A bending mandrel 62 is used to bend a pair of struts along surface (64), Fig. 9 (not shown). The bent strut member is introduced between the channel section strips S and the apices are welded using welding apparatus 31. The apparatus 31 comprises a fixed table 35 and one or more pairs of electrodes 37, 38 which are piston operated. The electrodes are mounted on a slide 41, Fig. 13, on the table, the slide being movable transversely by a motor 42. At a cut-off station C, Fig. 4, one or more cutters 32, which may be in the form of a rotating abrasive disc are used to cut off a predetermined length of truss member. A cutter is mounted on the shaft of a motor (45), Fig. 14 (not shown), mounted on a pivoted bracket 46. The bracket is controlled by a piston (47) for swinging movement into and out of the path of the truss member. A stationary welder is used, Figs. 16, 17 (not shown), to form the end structure of the truss member and comprises a pressure member (75) pivotally mounted on a slide (76) which moves longitudinally of the truss member. Movement of the member bends the free end (E) of an end strut member and simultaneously welds the end strut to an associated channel member.

Title: Improvements in percussion fuses for aircraft bombs and other purposes
IPC: F42C1/04
Filed: 1924-06-13
Abstract: 218,991. RÚmondy, L. E. July 12, 1923, [Convention date]. Projectile fuzes.- Percussion fuzes are provided with a fuze carrier adapted to be moved longitudinally on impact according to the resistance of the target encountered, to cause the fuze to act with or without delay. As shown in Fig. 1, the fuze mechanism is of the kind described in Specification 172,326 and comprises a casing F carrying firing-pin F<1> and containing a percussion cap F<2> held away from the firing-pin by a spring F<3>. This fuze is mounted between a stop c<1> and a spring f in a fuze carrier C, C<1>, C<2> which is secured by an annular nut E against a washer c<2> bearing against a collar D<1> on a delay device D. This device, as described in Specification 213,547, contains a delay charge d and a relay charge d<3>, and has flash holes d<1> opening :out from the delay charge. Additional holes d<2> opening out from the relay charge d<3> are now provided below the collar D<1>. On impact with a highly resistant target, the fuze carrier C, C<1>, C<2> is rammed in and shears the collar D<1>, whereby the holes d<2> are uncovered to the flash from the percussion cap F<2> and explosion of the projectile occurs without delay. On impact with water or like non-resistant target, however, the collar D<1> is not sheared, and the flash is transmitted by the delay charge d. The casing F may be arranged to project beyond the nose of the projectile A. In a modification, the flash holes, d<2> are arranged above the collar D<1> and are adapted to be closed when the fuze carrier is rammed in, the explosion being thus delayed when the target offers a strong resistance, but is immediate when the target is weak. In this modification, the fuze is held in its carrier by a split ring. In another modification, Fig. 3, the ramming in of the fuze carrier C by a strong target capable of shearing a washer D<1> causes a firing-pin G<1> to strike a percussion cap G' producing immediate explosion, the cap G<3> being normally held away from the firing-pin G<1> by a spring G<2>, and the casing G carrying the firing-pin and enclosing the cap being normally held forwards by a spring H. When. a weak target is encountered, the fuze mechanism G<1>, G<3> acts only when the casing G is driven back by the explosion of the relay charge d<3> after the combustion of the delay charge d, which is ignited by the nose fuze. In the nose fuze shown in this Figure, the percussion cap F<2> bears against a washer F<4> having ears f<4> held between a sleeve C<2> and a shoulder c', and the casing F has slots F<3> for slidingly accommodating the ears f<4> of the washer. The displacement of the fuze carrier may control the immediate or delayed action by opening passages by perforation, or by means of an auxiliary device, such as a throttle. A number of shearing stops may be provided to make the delay longer or shorter according to the resistance of the target.

Abstract: 1367290 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 28 March 1972 [21 May 1971] 14420/72 Heading H3B The sensing positions of a plurality of channels along which cylindrical domains are propagated are staggered, and the respective sensing devices connected in series to a common output circuit, so that advancing domains in identical positions in each channel together produce a series of non-overlapping output pulses. The domains 26 are established in a biased magnetic sheet 10 of orthoferrite or garnet, and as shown in Fig. 1, may be propagated by a rotating magnetic field H along parallel channels 1-8 defined by permalloy T-bar overlays. Series connected sensing devices 14-1 to 14-7, which may be magnetoresistive or Hall effect, are positioned in staggered order across the channels, each group of four sensors being connected to a sense amplifier 18 and to an energizing constant-current source 16. The output of the sense amplifier 18, which consists of spaced pulses each representing the arrival of a domain at a sensing position, Fig. 2 (not shown), is applied to a utilization circuit 20. A control circuit 22 linked with the field coils producing the rotating magnetic field H correlates the pulses and the channels. In a modification, Fig. 3, the propagation channels are defined by conductor loops 28 which are pulsed sequentially by signals # 1 , # 2  and # 3  from a propagation pulse source 24 to shift an associated domain towards series connected sensing devices 14-1 to 14-3. A further embodiment, Fig. 4, has a single conducting sense loop 30 extending at an acute angle across eight propagation channels defined by T and I bars. Alternatively magneto-optic sensing may be used with an optic beam scanning at an acute angle across the channels.
