Title: Improvements in and relating to Sight-testing or Eye-examining Instruments or Apparatus.
Inventor: HOSFORD JOHN STROUD
IPC: A61B3/024
Filed: 1917-02-24
Abstract: 113,641. Hosford, J. S. Feb. 24, 1917. Sight-testing apparatus.-A perimeter is so constructed that the field of vision has within it only the fixed and movable spots on the front of a dead black test board or disk. The movable spot x is either made of or carries a small piece of iron or other magnetizable metal and is moved in any desired direction by a permanent or electro magnet y placed behind the board. In the form shown in Fig. 1, the head-rest c is adjustable vertically and laterally by racks and pinions and the board a is mounted in a frame s vertically adjustable in guides t, which are mounted on slides d longitudinally adjustable in side guides e by means of a rack and pinion. A chart z, marked by a pricker or pencil 3, is held against the back of the board by a hinged frame u. The magnet y, which as shown is made hollow to receive the pricker and forms the armature of a coil 2, may be counter-balanced by a weight 9 or may be supported by lazy-tongs and a ball-and-socket joint or may be adapted to slide in a radial slot in a rotatable frame so that it may be moved into any desired position on the chart. The movable spot x may be placed in a thin liquid trough, the front of which is made of glass, or it may be held in position on the board by suction or magnetically by employing an iron test-board which is magnetized, for example, by a coil placed behind it.

Title: Improvements in and relating to gain control circuit means for line and radio telephony
Inventor: SHARP LEONARD WILLIAM DESCARRI
IPC: H04B1/64
Filed: 1952-02-01
Abstract: 715,401. Automatic volume control. PLESSEY CO., Ltd. March 4, 1953 [Feb. 1, 1952], No. 2763/52. Class 40 (4) [Also in Group XL (c)] In a volume compressor arranged to mute in the absence of signals so as to suppress background noise, there is produced a negative D.C. potential proportional to the output, which is applied to a compressor valve as grid bias via two independent paths in parallel, which respectively effect muting and volume compression. Signals are applied to the compressor valve V1 via a transformer T1 and are taken from a subsequent output valve V1 via transformer T2. A rectifier M3 is connected by way of a potentiometer R12, 13 and blocking condenser C3 to the anode of valve V2, and produces across condenser C2 a negative potential proportional to signal output. In the absence of signals the valve V1 is given a positive bias via resistances R8, 10, 9, 2, so that grid current renders the input impedance low relative to that of series resistance R1: rectifiers M1, 2 are biased to be respectively conductive and non-conductive. As the output level and the negative D.C. potential across condenser C2 increases, the potential of the point "B" moves negatively until grid current in the valve V1 ceases, giving full gain. The rectifier M2 becomes conductive and clamps the potential of point "B". Upon sufficient further increase of negative potential across condenser C2 the rectifier M1 is rendered non-conductive: the potential is then communicated to the grid of valve V1 via resistance R6, 3 so as to cause volume compression. The point at which muting occurs may be adjusted by means of the potentiometer R8 and the compression point by resistance R5.

Title: Improvements in the manufacture and production of aromatic acid chlorides

Filed: 1928-02-02
Abstract: 310,909. Henderson, B. W., Percival, J. G., and Imperial Chemical Industries, Ltd. Feb. 2, 1928. Benzoyl chloride is made by chlorinating benzyl alcohol. Either chlorine or chlorine mixed with hydrochloric acid is used as chlorinating agent. In practice this reaction is combined with the ordinary method of chlorinating benzaldehyde. Thus a mixture of benzyl alcohol and benzaldehyde obtained by hydrolysis of the chlorination product of toluene (i.e. benzyl and benzal chlorides) is chlorinated to yield pure benzoyl chloride. In examples, (1) benzoylchloride is obtained by chlorinating benzyl alcohol, (2) a mixture of benzyl alcohol and benzaldehyde (obtained by hydrolysis of crude benzal chloride) is chlorinated to yield benzoyl chloride. o- and p-Chlorbenzoyl chlorides may be made in an analogous manner by chlorinating the corresponding hydrolyzed chlorbenzyl chlorides or a hydrolyzed mixture of the corresponding chlorbenzyl chlorides and chlorbenzal chlorides.

Abstract: 122,305. British Thomson - Houston Co., (General Electric Co.). Feb. 26, 1918. Controllers, actuating - mechanism for.-The resistance in series with the field winding of a motor is shunted by two pairs of contacts operated by centrifugal means; one pair is normally open, and the other is normally closed. These are used for speed regulation, and additional contacts are used to disconnect the motor at a predetermined speed. The apparatus consists of three rings 1, 2, 3 rotated by the motor shaft. The arm 8 is pivoted on and electrically connected to the ring 2, and its free end works between the contact 11 on the ring 1 and the contact G on the ring 3. The arm 14 is pivoted on the ring 1 and is associated with a contact 16 on the ring 2. The rings are connected to the field winding 20 and resistances 24, 28 as shown. When the motor is at rest, the arm 8 engages .the contact 11, thereby short circuiting the resistance 28 so that the motor starts with a strong field. When the motor reaches a predetermined speed, the arm 8 moves away from the contact 11 and the resistance 28 is inserted in the field circuit. At a higher speed, the arm 14 engages the contact 16 and short-circuits the resistance 28 to strengthen the field and to slow up the motor. The arm 14 will therefore engage and disengage the contact 16 to keep the speed constant. At a high predetermined speed, the arm 8 engages the contact 6 to short-circuit and de-energize the circuit-breaker winding 23, thus causing the circuitbreaker 22 to disconnect the motor from the supply.

[Also in Group I] In a bean stringer and slicer in which a bean is pushed into and separates the split halves 5, 6 of a cylindrical guide carrying top and bottom stringing knives 7, after which the bean advances through a series of slicing knives 4 fixed in a removable grid 3 the grid is prevented from falling out of its aperture 2 in the frame by limiting the upward sliding movement of the guide half 5 by abutment clips 10 detachably fixed on the posts of the frame, so that at least the lower edge of the guide continues to overlap the grid 3 and hold it in position. The lower guide half 6 may be similarly limited in its movement by clips 14. The clips 10 and 14 also prevent the guide halves 5 and 6 from slipping off the posts of the frame. The guide halves 5, 6 are yieldingly pulled towards each other by springs 11 spanning projecting hooks 12 on each guide half, but are held separate by abutting against a side lug 13 integral with the handle. A fixed auxiliary knife 8 is provided for topping and tailing the beans. An opening 15 is provided in the handle 1 so that the device can be clamped to a table. In a modification, Fig. 6, the guide halves are pivoted to move apart horizontally when a bean is pushed through but this movement is similarly limited to ensure that the removable grid of knives is prevented from falling out by being overlapped by some part of the guide halves.
