Abstract: 234,718. Sidwell, E. W. Dec. 1, 1924. Boots, shoes, and lasts, measuring for.-Foot and last measuring apparatus of thekind comprising a sole plate with devices for locating the heel, toes, and ball joint are further provided with means for automatically converting girth measurement and length measurement at various points into a code letter or indicator denoting the combined relationship of girth and length measurements. This is done by means of cords, the ends of which are attached to fixed or moving points on the machine, while the other ends register a code letter in an indicator. Various other measurements including toe angles are similarly recorded and all may be printed on a card. A main slide bar 1 is mounted on an inclined frame so that all parts slide back after use to zero. A foot is supported on foot-rests 2 and centred in adjustable heel pieces 6 against a back-rest 7, and the ball of the foot is located on a part 8 pivoted to a slide 9 on the bar 1. Mutually-adjustable side pieces 10 centre the foot. To the ball joint locators are secured tubes 12 through which passes a measuring cord 13 for taking the girth of the foot at the ball joint. One end of the cord 13 is attached at 14 to a fixed part of the apparatus and the other 15 to an index box 16 sliding in a groove in the central slide 9. The size indicated, A, B, C, &c. is compounded of the length to which the slide 9 carrying the ball-joint locator is moved and the actual girth of the foot at that point. For convenience in operation, the cord 13 is made in two parts joined by a connection over the ball joint. Similar cord systems in tubes 19 are employed for measuring the ankle and instep girth, the ends of these cords being attached at 18 to the slide 9 and to dimension index boxes 20 sliding in grooves in a fixed part of the framework. A toe-locating device 21 is provided on a slide 22 and also a toe-angle locator 23, preferably pivoted, and provided with linkage 24 and telescopic rod connections 25 to an index box 29. The anglelocating device is adjusted so that its spindle 32 coincides with the axis of the apparatus. A button 33 then connects the rod system 25 in zero position. All the indicators can be pressed upwards to register on a card placed in a slot 26.

Title: Improvements in wireless receiving apparatus
IPC: H04B1/12
Filed: 1919-11-24
Abstract: 160,502. Chandler, C. K. Nov. 24,1919. Atmospherics and undesired signals, eliminating or limiting; thermionic amplifiers and detectors; directive signalling. - In wireless receiving-apparatus, interference from a magneto or other disturbing source is obviated by a corrector circuit containing inductance and capacity, the inductance of which is coupled to the disturbing source so that the energy picked up by the corrector circuit directly from the magneto neutralizes that picked up by the receiving-circuit from the same source. Fig. 1 shows the corrector circuit 1, 2, 3, which is capable of being tuned, connected in parallel with the primary of an intervalve transformer. The lead from the inductance 1 to the primary of the transformer may be dispensed with when dealing with interference of very high frequency, the circuit then acting as an aerial picking up energy from the source M. Interference from atmospherics or from powerful stations may be obviated by coupling the inductance in the corrector circuit to a small aerial in which the disturbance produces forced vibrations. The corrector circuit may be connected to the grid circuit of the receiving valve, either as shown in Fig. 2<c> or at the grid end or at the filament end. Suitable inductances or capacities may be arranged in the main receiver circuit such that, whilst the circuit is tuned to the received signals, the maximum energy is not picked up from the disturbing source. The range of the interfering waves and the phase differences between the effects of the disturbing source on the main and corrector circuits may be altered by inductances and capacities. When applied to aeroplanes, two corrector circuits may be used, one coupled with the amplifier and one with the main receiving circuit. In Fig. 4, which shows the arrangement for high frequency amplification, a small coil inserted in the main receiving circuit and corrector circuit for the rectifying-valve 5 are both coupled with the source. The leads from the magneto may he wound in a single coil in the form of a plait, each member of the plait being connected to one earth lead. The coupling may be either electromagnetic or electrostatic; if the former, it must be very loose to avoid electrostatic transfer of energy; if lack of space prevents sufficient looseness, a small coil is placed in series in the main receiving circuit and coupled with the source, or the coil may be used as an aerial coupled to the source. In the case of both high and low frequency interference, two corrector circuits may be used, one to correct for the high-frequency disturbance and the other for the low. Fig. 5 shows the invention applied to directional apparatus comprising two aeriaLs 11, 12 at rightangles connected through change-over switches 8, 13, 14, 15 to two corrector circuits 6, 9 and 7, 10 so that correction is applied when there is interference and the circuits are disconnected when there is no interference.

Abstract: 826,805. Indicating liquid levels. SHAND & JURS CO. Sept. 17, 1957 [Oct. 1, 19561, No. 29312/57. Class 123(1) In a liquid level gauging apparatus particularly for marine use comprising a float which is lowered by a graduated tape on to the liquid surface, the tape and tape drum can be removed for storage when the apparatus is not in use. The apparatus consists of a housing 11 mounted on an enclosure 12 fixed to the ship's deck overlying a tank 14 and carrying a reel 21 on which is wound a metal tape 18 graduations on which may be read through a window 19 in the top cover 127 of the housing. The reel 21 is mounted on a hub 22 within a separate compartment 11c in the housing, the compartment being filled with an anti-freeze fluid. The tape passes from the reel through an opening 63 in the compartment wall and over an idling pulley 29, its end being secured to a float 64 which is guided for vertical movement within the tank by wires 74, 76. In use the float is lowered to the liquid surface in the tank, when the level therein can be read through the window 19, by rotation of the reel, the drive means consists of a pin 49 which engages a lug 51 formed on the reel hub. The pin is carried on a crank arm 48 attached to a shaft 44 passing through the wall of the compartment 11c and carrying on its outer end a drum 42 upon which a counterbalance spring 58 is wound when the tape is lowered, the spring ensuring that the float always rests at the same level in the liquid. The drum 42 is driven by a pin 97 which engages a lug 98 in the drum, the pin 97 being carried by a shaft 93 which is rotated by the manual operation of a crank handle 91. When the apparatus is to be out of use for a lengthy period, damage by corrosion &c. to the tape and reel is avoided by removing these from the housing. The float is wound up into the enclosure 12 and suspended on a hooking member 118a, the tape is then disconnected and removed with the reel through the hinged top cover 127.
