Title: Improvements in or relating to the production of protective coatings upon aluminum and aluminum alloys
Inventor: SCHAABER OTTO
IPC: C25D11/06
Filed: 1950-02-13
Abstract: 673,391. Anodic treatment of aluminium base metal. JUNGHANS, S. Feb. 13, 1950, No. 3672/50. Class 41. A process for the production of an oxidic coating on an aluminium base metal comprises anodizing the metal on an electrolyte consisting of a substantially water-free fused salt bath, which is such that upon electrolysis oxygen is liberated at the anode, the bath being maintained at a temperature between 140‹ C. and the melting point of the metal. The salt used is preferably an alkali-metal or ammonium nitrate or nitrite. Potassium dichromate is also suitable. Decomposition of the nitrates may be accelerated by the addition to the bath of catalysts, for example copper or iron compounds or lead oxides. Copper oxide and copper nitrate are mentioned as examples. Copper and iron compounds may be obtained by using copper and iron electrodes. To ensure the production of light transparent coatings a local potential which normally persists for a short time after current has been switched off, should be reduced or destroyed. This may be done by using an electrolysing current which is interrupted or which is an alternating current or a pulsating current. A suitable current is provided by superposing a direct current of N-2 volts upon an alternating current of N volts. Anodizing treatment may be preceded by etching for a short time in a caustic soda solution of about 5 to 15 per cent concentration, and may be followed by boiling in a 2 to 5 per cent waterglass solution.

Title: A new or improved method of laying pipes in land for drainage purposes
IPC: E03F3/06
Filed: 1925-02-10
Abstract: 243,574. Fowler & Co. (Leeds), Ltd., J., and Robinson, J. Feb. 10, 1925. Laying pipes.-Pipes for draining soft subsoils &c. are laid by forming a hole beneath the surface by means of a mole-drainer, making gaps or openings at suitable distances along the line of the drain hole, passing lengths of piping down the gaps and inserting them one after another in the drain hole by means of a ram or the like. When the pipe lines are completed a few pipelengths are passed down each gap to connect the adjacent pipe lines, and the gaps are filled in with soil. A ram suitable for forcing lengths of piping into a hole is shown in Fig. 1. Links 5 operated by a hand-lever 6 engage a rack 4 having a plunger 1 at the forward end, which forces the pipes through the sleeve 14. Varying positions on the hand-lever 11 12, 13 allow varying degrees of mechanical efficiency in the ram. A conical cap 15, Fig. 7, may be fitted in the forward end of the foremost drain pipe to prevent the pipe from fouling the drain hole and filling up with soil while the pipe is being pushed forward, and the forward end of each drain pipe 3 may be slightly rounded for the same purpose.

Title: Signal sequence detectors
IPC: G06F7/02
Filed: 1962-02-01
Abstract: 923,541. Electric selective signalling. AMP Inc. Feb. 1, 1962 [Feb. 14, 1961], No. 3789/62. Class 40 (1). A signal sequence is detected by shifting a set state along a transfluxor shift register, each shift being caused by the reception of a signal of the sequence. A clear state is that state in which flux is clockwise about the main aperture of the transfluxor while a set state is that state in which part of the flux is in a clockwise direction and part in anti-clockwise direction. The left-hand minor aperture of a transfluxor is not used. The direction of flux at each step (N) is shown by the arrows beneath Fig. 1. Initially all the cores are cleared (1). It is required to detect the sequence ATOM. An A-signal opens gate 18 and energizes windings 28 and 40. Winding 28 opposes winding 40 on core 11 but has more turns. Core 11 is set (2). Source 48 now energizes windings 45, tending to polarize the flux about the right-hand minor apertures 11T to 14T in anticlockwise direction, and 40 which opposes winding 45 and is sufficient to overcome its effect on cores 12 to 14. The flux about aperture 11T is switched since core 11 is in set condition (3). An immediately following T-signal will energize windings 30 and 40. There will be no immediate effect on core 12 since the windings cancel out. However, winding 40 will reset core 11, thus energizing transfer winding 50. This will set core 12 (4). Source 48 is now energized to reverse the flux about aperture 12T (5). If the signals A.T.O.M. are received in sequence this process continues until core 14 is in the set state with the flux about aperture 14T reversed (9). Energization of source 42 or the reception of any other signal after the M-signal will clear core 14 by means of winding 40 and the output on winding 56 is an indication that the desired sequence has been received. If at any time a signal other than of the required set is received winding 30 is energized and the set core is cleared by winding 40. If a signal of the set is received out of sequence the core will also be cleared. Thus, if an O-signal is received after the A-signal windings 32 and 40 are energized, core 11 is cleared but the transfer winding 50 will have no effect on core 12 since it is opposed by winding 40. Windings 32 and 40 in opposition have no effect on core 13. A second embodiment is described in which each core is associated with two signals (Fig. 2, not shown). The source 48 is dispensed with and its function performed by a signal of the sequence. Thus, if the sequence ATOM is to be detected only two cores will be used. The A-signal will set the first core; the F-signal will reverse the flux about the minor aperture; the O-signal will clear the first core and set the second; and the M-signal will reverse the flux about the minor aperture of the second core. The second embodiment describes the detection of the signal AUTOMATE by apparatus in which the A-signals for example energize the same winding. Specification 922,466 is referred to.

Title: Improvements in or relating to rat traps
IPC: A01M23/34
Filed: 1944-03-02
Abstract: 576.783. Rat traps. MARRIAGE, E. B. March 2, 1944, No. 3918. [Class 5 (i)] Relates to rat traps of the kind comprising a base, a spring-actuated movable member thereon, a noose-forming wire attached to the lever, and an apertured abutment for receiving the wire. According to the invention the wire is attached to the lever by a rigid link and the abutment is so disposed that the link is located in its aperture when the trap is set, the link being secured in its set position by resting upon a support whereby a slight pull on the wire causes the lever to move laterally away from the support thus allowing the spring- actuated member to operate upon the wire. In the construction shown a coil spring is mounted on the base board 1, to which is also connected by a staple 14 a wire which passes through the spring and which has a portion forming with the spring extension 6 a stirrup to which is connected a tube 9. Tube 9 has an eyelet 10 engaged by an eyelet on a rod 12 the other end of which carries a brass wire 13 formed with a noose 15. To set the trap the wire and rod 12 are passed through a ring 17 of a wire frame 16 secured to the base board, and the rod 12 is then sprung upwardly until it rests on the top of a pointed wire pillar 18. Any pull on the wire, exerted for instance by a rat entering the noose, dislodges the rod 12 from the pillar and thereby enables the spring to pull the rod and wire through the ring 17 which acts as an abutment for tightening the noose. An adjustable extension 2 is adjustably connected to a base board so that the trap may be pressed into the side of a nick as shown. A safety catch 20 may be prpvided to hold the parts in the operative position.
