Title: Improvements relating to the voltage control of a.c. generators
IPC: H02P9/14
Filed: 1943-06-07
Abstract: 570,872. Alternators. BRITISH THOMSON-HOUSTON CO., Ltd., POHL, R., and MATHEWS, P. June 7, 1943, No. 9133. [Classes 35 and 38 (iv)] The voltage of ar alternator is main tained constant under varying load by making its excitation the rectified resultant of a current proportional to the load and a current proportional to, but in quadrature with the voltage, the latter component being obtained from inductance and capacity in parallel with the generator. In the form shown, the current feeding the field winding 2 through the rectifier 5 is derived partly from the series connected condenser 4 and inductance 3 and partly from the transformer 6. The positions of the condenser and inductance relatively to the rectifier may be interchanged. Specifications 24099/02, [Class 35], and 439,955 are referred to.

The active region 12 of the layer 5 which, with substrate 3, defines the junction 2, is bounded laterally by the surface 13 and by at least one groove 11 extending at least partly through the layer 5 and aligned parallel to the surface 13. Preferably further grooves 9, 10 complete the lateral boundary of the active region 12, which is contacted by a conductive layer 8 extending through a contact window 15 in an insulating film 14. The layer 5 may be formed by diffusion, but is preferably provided by successive liquid phase epitaxial depositions of p-type Ga 1-y Al y As(0#y#0À5)SA, p-type Ga 1-m Al m As(0À1#m#0À7; y#m)5B and p-type GaAs on an n-type body 3 which itself comprises an epitaxial layer 3B of Ga 1-x Al x As(0À1#x#0À7; y#x) on a substrate 3A of GaAs. A cooling member may be soldered to the electrode 8. Figure 8 shows an assembly of a plurality of such diodes mutually isolated by grooves 21-25 the width of which increases with increasing depth. Each of the active regions 12A-C may be provided with a discrete electrode, or a common conductive layer may be provided to contact all the regions 12A-C.

[Also in Division C1] A row of four downwardly pointing rotary clamping heads 30 with suction bellows are set on the white-dried plates 16 by lowering the cross-member 26; as the lever 48 lifts the crossmember 26 the suction heads 30 lift the plates 16 from the moulds 14 on an endless conveyer 10. The heads 30 are then swung upwards about the shaft 28 until their sleeves 36 (Fig. 3, not shown) contact the drive belt 88 which then rotates the sleeves together with the heads 30 and the plates.  The edges of the plates are then engaged first by the harder bristles 98<SP>1</SP> of a rotating roller brush 98 and then by the softer bristles 98<SP>11</SP> as the brush is moved axially by the pin 108 which engages in the cam groove 106. The brush and sponge housings 94 and 96 are displaced along the guide rods 92 by the crank drive 102 so that the sponge belt 100 smoothes the edges of the plates. The plates are then gripped by the secondstage suction heads 60 at position 60<SP>1</SP> and then the plates are released by the heads 30 and carried without inverting to a stacking table 18. The second stage suction heads 60 can be rotatable about their axes so that they can engage the plates and rotate with them for additional grip during cleaning in position 60<SP>1</SP>.

Title: Machine for wood chipping
IPC: B27L11/02
Filed: 1953-04-10
Abstract: 737,384. Cutting up wood. ROTTMANN, E., [trading as'MOEBEL-FABRIK WESTFALIA - H. ROTTMANN]. April 10, 1952 [May 15, 1951], No. 9316/52. Class 145. A machine for chipping waste wood for the manufacture of boards comprises a rotating cutter drum 7 or disc 26 fitted with blades 17 and at intervals corresponding to the desired length of chip, with sawtoothed pre-cutters 21, the wood pieces 3 being fed to the cutters with their grain direction parallel to the length of the blades. The blades and pre-cutters are adjustably secured by wedges 19 and the precutters are mounted on springs 22. The wedges have relatively flat chip-receiving grooves 20 and the pre-cutters have teeth 23 followed by smooth ridges 24 of the same width as the chip grooves. The ridges 24 engage in the slots cut by the teeth 23 and prevent the wood being cut from over-penetrating into the grooves 20, thus leading to an undesired increase in the thickness of the chips. In the embodiment shown in Fig. 1, the wood is fed by toothed discs 13 which are mounted on spring- or weightloaded levers 14 and are driven by chain or other means from the main drive of the machine. An adjustable serrated backing plate 6 is fitted close to the cutter drum and the top wall 9 of the shoot and the front part 18 of the housing can swing upwards to give access to the cutter drum. In the disc version shown in Fig. 6, the wood pieces are fed along a guide 29 by a plunger 33 operated by a rod 32 and an eccentric drive, the guide 29 lying off-centre to the axis of the cutter disc 26 and being fitted with a hinged lid 31.

[Class 38 (iv)] A discharge lamp 1 for a motion picture camera or projector is arranged to produce one flash per cycle of the supply by connecting it to the supply transformer 3 in series with a rectifier 4 shunted by a resistance 5, the latter having such a value that during the half cycles for which the rectifier would normally prevent the flow of current to the lamp, a voltage is supplied to the lamp which is only sufficient to maintain the ionization thereof. Alternatively, a rectifier is employed having a resistance in the reverse direction corresponding to the value of the resistance 5 which can then be dispensed with. U.S.A. Specification 1,986,939 is referred to.

Title: Process for restoring the crimp of continuous filamentary material
IPC: D02G1/20
Filed: 1965-03-04
Abstract: Filamentary material, in the form of untensioned, twisted or non-twisted, continuous filaments of nylon or polypropylene possessing latent (and perhaps patent) crimp, is deposited in the form of overlapping flat loops or preformed coils across the width of a permeable supporting web e.g. a foraminous or open-mesh polyester or polyolefin fabric or spaced parallel threads thereof, travelling at a lower speed than the speed with which the material is supplied to the web so that the web supports ten to five hundred times its own length of filamentary material, and the full crimp is developed by heating the relaxed filaments with steam or a hot liquid while they are on the web.  The layer of filamentary material may be secured on the web by spaced holding threads or an endless belt moving with the web.  A dyeing package may be formed by rolling a multilayer assembly of the web and the crimped material.

A process for the continuous electrolytic production of titanium is carried out in a cell divided into a plurality of compartments each containing an electrolyte sharing a liquid alloy electrode containing the electrolytes of said compartments, and containing titanium as a solute and a solvent of at least one of the groups of metals less electropositive than titanium with respect to halogens, (as hereinafter defined), and comprises electrolysing in one compartment of the said cell a fused salt electrolyte composed of at least one of the alkali and alkaline earth halides between the said liquid alloy electrode acting as a cathode and a dependent isoluble anode immersed in the said electroylte. Simultaneously feeding at least one titanium halide below the surface of the said liquid alloy electrode in the said compartment so as to discharge halogen at the said anode and supply the said liquid cathode with titanium, and simultaneously, in another compartment of the said cell, electrolysing a fused salt electrolyte composed of at least one of the alkali and akaline earth halides as a solvent and containing a lower halide of titanium as a solute, between the said liquid alloy electrode acting as an anode and a solid cathode immersed in the said electrolyte, thereby selectively dissolving the said titanium from the said liquid alloy electrode and depositing titanium on the said solid cathode. Specified metals for the liquid alloy are silver, tin, antimony, lead, zinc, copper, bismuth, cadmium, iron, nickel, colbalt or mixtures thereof. Specified alkaline earth metal halides include those of magnesium. Specified halides of titanium are the tetrachloride, trichloride and dichloride. As shown, the electrolytic cell 10 is formed into two compartments by partition 11 of graphite.
