Title: Improvements in carrier wave signalling systems
IPC: H04B3/10
Filed: 1938-04-01
Abstract: 513,229. Repeaters for carrier systems. STANDARD TELEPHONES & CABLES, Ltd., and HODGSON, K. G. April 1, 1938, No. 10094. [Class 40 (iv)] In a carrier system in which a pilot current for controlling volume regulation, volume indicators or frequency synchronization accompanies the signals in the repeaters, it is arranged that the terminal apparatus, which carries signals only, overloads at a lower level than the repeaters. By this means, temporary overloads of the repeaters and consequent false variations in the level of the pilot current are minimized. Impedance changes due to overloading of the terminal apparatus are prevented from affecting the output of the pilot current source by associating the terminal apparatus 11 and the source 14 with the line by means of a hybrid coil 15.

Abstract: 591,026. Electric resonators highfrequency discharge apparatus. GOODALL, M. C., and WRIGHT, C. S. April 21, 1945, No. 10098. [Classes 39 (i) and 40 (iii)] A coaxial resonator 1, 2, is tuned by moving a capacitive disc 9 towards or away from the end of the half-wave inner conductor 2, which is supported on a heat-conducting copper pillar 3. The disc 9 is of the same diameter as the conductor 2. Movement is effected bv turning a, screw-threaded 8, which is enclosed in a quarter-wave sleeve 14 -to give the effect of good contact between the shaft 8 and end plate 7. An approximately linear law of tuning is obtained when the diameters of the shaft 8 and central support 3, which may be of metal, are a quarter of those of the inner conductor 2 and tuning-disc 9. The inner diameter of the outer conductor 1 is twice as great, and is ¢# times the maximum working wavelength. When the resonator forms part of an oscillationgenerator of the velocity-modulated reflector type, the end wall 4 is provided with spring fingers 20 for making contact with an electrode 19 of a valve 18 of the disc-seal type, corresponding fingers 16 being provided on the inner conductor for another electrode 17. For connection to an external circuit a loop or probe coupling 23 is inserted close to the central pillar 3, on the side of it opposite' to the tuning-disc 9. This oscillation-generator may be ganged with a crystal mixer comprising a resonator similarly constructed but without the valve 18, a set screw for presetting the tuning being arranged instead of the valve in the end wall 4, while a crystal takes the place of the coupling 23, Fig. 1 (not shown).

Title: Eye protector
IPC: A61F9/06
Filed: 1942-07-30
Abstract: 564,257. Eye protectors. McDONALD CO., B. F. July 30, 1942, No. 10664. Convention date, March 14. [Class 97 (i)] [Also in Group V] An eye protector in which lens and frame are integral is made from plastic material, such as cellulose acetate or polymerized methyl methacrylate, injected into a mould at-high pressure and temperature so that 'the material enters the mould in substantial alignment with the surfaces of the lens cavity of the mould at the entrance thereto. The lens is concave towards the eye and conforms to the contour of the face about the eye; and the frame is constituted by an inwardly-directed peripheral extension of the lens, terminating in a face-engaging edge and sufficiently deep to permit free eye movement while affording a wide field of view. The frame portion may be thinner than the lens portion, and the effect of this and also of the inward disposition of the frame portion is to cause the plastic material to flow into and fill the lens cavity in the mould before it completely fills the frame cavity. The temperature and pressure of the injected material may also be regulated to this end. Protectors for both eyes are joined by a bridge of adjustable width. The protector shown in Fig. 1 comprises lenses 2, concave towards the eye, each with an integral inwardly-extending frame 3 terminating in a rounded or beaded edge conforming to the contour of the face round the eye. Holes 9a in the nasal sides of the lenses receive a resilient cord 9 forming an adjustable bridge ; and holes 10a are provided in the other sides to receive a head strap 10. Fig. 9 shows apparatus for moulding both lenses simultaneously, comprising two mould pieces 30, 31 forming when assembled lens cavities 32a, 32b having the inwardly-directed peripheral portions necessary for moulding each frame portion in one piece with its lens portion. Overflow cavities 45 may be provided to accommodate air pockets formed during the moulding. The injection nozzle is received in a vertical gate passage 35, communicating via horizontal ducts 35a constricted at 35b, with the lens cavities 32a, 32b, and in substantial alignment herewith at the points of junction. A depression in the mould piece 31 at the bottom of the passage 35 is shaped to form a shoulder in the plastic material which acts as a retainer for the moulded lenses when the upper mould piece 30 is removed. Pins 44 guide the movement of the upper mould piece on the lower piece, and a plate 41 provided with knock-out pins 40 is guided by pins 42 on the lower mould piece, additional pins 43' serving to hold it in position with respect to said piece. Vent holes 7 and the holes 9a, 10a for bridge and headband may be formed during moulding if projections are provided that may be withdrawn before the protectors are removed from the mould; or they may be formed subsequently as by drilling. A plate or shield to protect the eyes from glare may be placed over the upper side of each frame and held in place by securing it to the vent holes. Provision for attaching a vent baffle plate may also be made.
