Abstract: 381,210. Electrical musical instruments. MAcCULLUM, C. R. and MACCULLUM, A., 21, Gibson Street, Hillhead, Glasgow. July 1, 1931, No. 18955. [Class 88 (ii).] In an electrical musical instrument employing a photo-electric cell 9 and light-records of individual notes, on actuation of a shutter 5 by a key 1 a beam of light is caused by a slot 15 in a rotating cylinder 14 to traverse a stationary note-record on a film 10. Each note-record consists of a small patch having a density which varies in a vertical direction and relates to a few waves only. The height of a patch is the same as the distance between the slots 15 so that as a beam leaves at the lower edge of a patch, a fresh beam enters at the upper edge. The currents produced are passed through an amplifier 18 to a loudspeaker 19. The note records may be arranged on the film in rows representing the notes of an octave, and in columns representing the different octaves. The film may have noterecords relating to different instruments, the requisite part of the film being brought into position by e.g. a crank 20 on roll 11.

Title: Improvements in the regulation of rectifiers by means of grids
IPC: H02M7/15
Filed: 1935-07-03
Abstract: 459,443. Rectifying alternating current. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. July 3, 1935, Nos. 18996 and 18997. Convention dates, Nov. 1, 1934 and May 17, 1935. [Class 38 (ii)] A grid-controlled rectifier is automatically regulated to maintain constant voltage, constant current, or constant power output by an arrangement comprising a phase shifting impedance network for the grid potentials, one element of the network comprising a variably saturated inductance in which the saturating current consists of the difference between a standard current and a current proportional to the quantity to be regulated. In the arrangement shown in Fig. 1, the grids of a rectifier 1 are fed from transformers 31 through resistances and inductances 3 associated with saturating windings 30. The latter are fed from points 8, 10 with the difference between a standard current derived through a stabilizing resistance 4, transformer 5, rectifier 6 and smoothing circuit 7, 11, and a current proportional to the output voltage of the rectifier 1. A compound voltage characteristic may be imparted to the rectifier by causing the standard current to vary with load by energizing a winding 50 on the transformer 5 from a current transformer 12 on the primary side of the main supply transformer. A relay 13 may be arranged to introduce a stand-by stabilizing resistance 40 in the event of failure of the resistance 4. Switches 15, 16 may be associated with the ignition device or main circuit breaker of the rectifier in such manner that the transformer 5 is cut out when the rectifier is inoperative. In a modification, Fig. 2 (not shown), the saturating windings are fed with the difference between a standard current derived as in Fig. 1 and a current proportional to the rectifier load current derived through current transformers and an auxiliary rectifier. Fig. 3 shows a further modification wherein a current proportional to the rectifier load current is supplied through a resistance 70 and inductance 71 to a rectifier 73, and the saturation of the inductance 71 is varied in accordance with the voltage of the main rectifier 1 by a winding 72. Thus a current proportional to the power output of the rectifier 1 is delivered by the rectifier 73 and balanced against a standard current supplied by a rectifier 54, the difference serving to energize a saturating winding 55 controlling the grid phase shifting circuit 60 to effect regulation of the rectifier to constant power. Specification 412,773 is referred to. According to the Specification as open to inspection under Sect. 91, the controlling current may supply one field component of a synchronous machine instead of energizing a saturating winding of an inductance. This subject-matter does not appear in the Specification as accepted.

Abstract: The invention comprises 6-dichloromethylene and 6-dibromomethylene derivatives of D 4-3-keto-steroid compounds of the androstane, 19-nor-androstane, pregnane and 19-nor-pregnane series having a saturated B ring, and the preparation thereof by reacting a 3-enol ether or a ketal of a D 4-3-keto-steroid of the androstane, 19-nor-androstane, pregnane or 19-nor-pregnane series having a saturated B ring with a tetrahalogenomethane in which the halogen is either bromine or both chlorine and bromine.  An intermediate 6-trihalogenomethyl derivative is first formed which is unstable and slowly transforms into the desired 6-dihalogenomethylene derivative. The transformation may be speeded up by the action of an acid-binding substance such as pyridine or collidine, an organic peroxide or magnesium, or by irradiation with light of a wavelength between 2000 and 8000  .  In some cases it is possible to isolate the intermediate 6-trichloromethyl or 6-tribromomethyl steroid of the above series. In the examples the following compounds are prepared: 6-tribromo (and trichloro)-methyl-testosterone, 6-dibromo (and chloro)-methylene-testosterone, 6-dibromomethylene - testosterone acetate, 6 - dibromomethylene - 17a  - methyl - testosterone, 6 - dibromomethylene - 19 - nor - testosterone acetate, 6 - dibromo (and chloro) - methylene - progesterone, 6 - dibromemethylene - 17a  - hydroxyprogesterone and the corresponding 17-acetate, 6 - dibromo - methylene - 11 - desoxyacetate, 6 - dibromo - methylene - 11 - desoxycorticosterone acetate, 6-dibromo-methylene-17a  - hydroxy - 11 - desoxycorticosterone 12 - acetate, and the 20 - ethyleneketal of 6-dibromomethylene-cortisone acetate.
