Patent GB-796446-A (GB)
Title: Improvements in or relating to the production of phosphorus-containing polyester resins
Inventor: COATES HAROLD
IPC: C08G79/04
Filed: 1956-03-09
Abstract: A phosphorus-containing polyester resin is made by effecting a transesterification reaction between a dialkyl phosphite (e.g. dimethyl or diethyl phosphite) and an aliphatic glycol (e.g. ethylene glycol, tetramethylene glycol, pentamethylene glycol or 2-methyl-pentanediol-2,4).  Reaction is generally effected in an inert atmosphere at 80-200 DEG  C. while the monohydric alcohol liberated is distilled off.  The transesterification is completed by heating under diminished pressure and at a temperature such that any unreacted glycol is distilled off.  Catalysts, e.g. sodium, and/or magnesium, sodium amide, sodium alkoxide or the corresponding potassium or magnesium compounds or phosphoric acid may be used.  The products are useful in the manufacture of flame-resistant resins, paints and lacquers and also in the manufacture of lubricant additives and hydraulic fluids.

Title: Regulatable a.c apparatus
Inventor: HINKSMAN ERNEST ALAN
IPC: H01F29/06
Filed: 1969-02-12
Abstract: 1279011 Control of AC motors; supply systems for electric furnaces. MIDLAND TRANSFORMER CO Ltd 6 Feb 1970 [12 Feb 1969] 7510/69 Headings H2H and H2J A three-phase apparatus, such as an electric motor or furnace or a rectifier, is regulated by an auto-transformer having a winding connected between two terminals of a three-phase A.C. supply whose third terminal is connected to one input terminal of the apparatus, the other two input terminals of which are connected to respective taps on the autotransformer, these taps being movable in synchronism to adjust the voltage between them from zero to the full interphase voltage. In the described embodiment, the apparatus is a motor 10 and the taps 20, 21 move from an initial position at the ends 27, 28 of the autotransformer 18, 19, corresponding to shorting out of the winding 14 of the motor which will thus not run, to a final position at the ends 29, 30 corresponding to full speed of the motor. The construction of the windings 18, 19 and the taps 20, 21 may be as described in Specifications 1,221,647, 1,238,295 and 1,241,956, in which case the taps 20, 21 can remain in any desired position between the ends 27, 29 and 28, 30. Such action is not possible if the taps 20, 21 comprise contact elements only of a material of low electrical conductivity, in which ease the tap movement between the ends is progressive with no stopping. The taps 20, 21 may be moved by the means described in Specification 1,263,716, which also explains how this means (an auxiliary motor whose movement is programmed) opens a contactor 32 to de-energize the autotransformer 18, 19 when the taps 20, 21 have reached the ends 29, 30 and the full load current of the motor has been transferred to auxiliary contacts 33, 34 and 35, 36. This transfer may be effected by causing the high conductivity contacts of the taps 20, 21 to bridge the auxiliary contacts or by providing further contacts to bridge the auxiliary contacts if the taps 20, 21 comprise only low conductivity contacts. The autotransformer may comprise a single coil wound as a shell and having taps which cross over to reverse the direction of rotation of the motor, Fig. 3 (not shown).
Patent GB-125118-A (GB)
IPC: F42C15/21
Filed: 1916-05-26
Abstract: 125,118. Owens, J. S., and Wells, E. May 26, 1916. Projectile fuses.-Relates to percussion fuses which are sensitive to impact in more than one direction. According to the invention, a striker ib surrounded by an annular weight within the fuse body, the striker having a. collar which bears against the base of the weight, so that a forward or tilting movement of the weight forces the striker against a percussion cap. In the fuse shown in Fig. 1, the striker consists of a tube 4 containing priming-composition and having a disk 9 thereon. The striker is normally pressed back by a spring 10 so that the disk 9 bears against the base of a heavy tube 7 surrounding the striker. When impact occurs, the striker 4 is moved forward against a cap 5 by the tilting, or under the direct pressure of the weight 7. To render the fuse sensitive to a fall upon its base, the plug 3 containing the cap 5 may be made slidable axially. The percussion cap may be mounted on the striker. Various forms of safety devices may be used, such as a split-pin passing through a recess in the fuse body and through the striker. The safety pin may be acted upon by a spring in such a way as to be automatically withdrawn from engagement with the striker after being released by the set-back of a ring or other locking-device on discharge of the projectile. Figs. 3 and 4 show examples of such arrangements. In the form shown in Fig. 3, the safety pin 11, acted on by a spring 13, is normally locked in the operative position by a hand-operated pin 14 and an inertia ring 16. In the modification shown in Fig. 4. the member which locks the safety pin 11 is a bolt 21 which sets back on discharge and disengages itself from lugs 19, but is prevented from falling away from the fuse and thus freeing the pin 11 until the projectile has passed out of the gun 18. In a further construction, the safety device comprises a split-pin which cannot re-engage winth the striker after being withdrawn; complete withdrawal of the pin is prevented by a stop. The Provisional Specification describes also other modified arrangements of the safety pin, and states that, in one construction, the pin may be withdrawn by a spring-operated lever. The provision of a sliding member which normally locks the safety pin and is withdrawn by means of a weight attached by a cord is also described.

Abstract: 1468368 Magnetic heads MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Feb 1974 [20 Feb 1973 (2) 11 Aug 1973] 7633/74 Heading G5R A magnetic head has parallel first electrically conductive coil segments 6 on a substrate 5, a first magnetic layer 9 extending across all of segments 6, second electrically conductive coil segments 12 formed across layer 9 and serially connecting segments 6 to constitute a head coil around layer 9, segments 12 being formed separately from and subsequently to segments 6, a second magnetic layer 11 magnetically coupled to layer 9, and a transducing gap defined between layers 9 and 11 by a non-magnetic material layer (10), Fig. 6 (not shown), formed between side end portions of layers 9 and 11. The segments 6, Fig. 7, of copper or aluminium are formed by deposition, evaporation, diffusion, anodic oxidation or implantation on a substrate 5 of silicon semi-conductor or glass. An insulating layer 32 of silicon dioxide is then formed by thermal oxidation, evaporation or epitaxial growth, the magnetic layer 9 of permalloy or Serdust is formed by evaporation or sputtering and a further silicon dioxide film 33 applied over layer 9. End parts 6<SP>1</SP> of segments 6 are exposed by photo-etching and the coil segments 12 applied by deposition or evaporation. The non-magnetic gap-defining layer (10), Fig. 6 (not shown), is applied to end part (7) of layer 9 and the second magnetic layer 11 is formed in the same manner as layer 9 so that it only overlies the end parts (7), (8) thereof. The layers 9, 11 may be rendered anisotropic, with the hard axis parallel to the head coil axis, by depositing the magnetic material in the presence of a magnetic field. The required shapes of the various layers are provided by selective photo-etching. A multitrack head may be produced by forming a plurality of such unit heads on a common semi-conductor substrate on which head switching and amplifying circuits may be formed by integrated circuit techniques. The centre taps of balanced coils (70), Fig. 12 (not shown), of a multitrack head may be connected via respective switching transistors (73) to a common power supply bus (82), a first common terminal (80) being connected to first ends of coils (70) via respective diodes (72) and a second common terminal (81) being connected to second ends of coils (70) via further respective diodes (72<SP>1</SP>), terminals (80), (81) being connected to the output of an amplifier for the signal to be recorded. Clock pulses applied to ring counters or shift registers (74), each connected to a respective transistor (73), cause the unit heads to be driven in sequence thereby providing recording tracks (53), Fig. 10 (not shown), oblique to the transport direction of a magnetic tape (51). The circuit may be used with clock pulses of 5 MHz p.r.f. to record video signals by means of amplitude modulation. The head assembly may be used for playback by providing each unit head with a bias coil winding in order to alter the reluctance of the magnetic core.
