Filed: 1938-06-30
Abstract: 511,643. Making rods and wire. MAUTSCH, R. Tune 30, 1938, No. 19475. [Classes 83 (ii) and 33 (iv)] Rolling; shearing.-Small sectional rod or wire is made by shearing large pieces of metal, which may be scrap, into fine shreds which are passed immediately, to avoid oxidation, to rolls which cause them to cohere into a continuous length. Large scrap such as old ships plates, axles, shafts &c. after being cleaned may be used. As shown, an electric motor 3 drives a shaft 4 and thereby by worm gearing 14 and belt gearing a feed roller 20, and by bevel gearing 5 a crank shaft 7 on which are mounted cranks 8 transmitting motion to cutters 10. The cutters are V- shaped and shear the large metal piece 2 into thin elements 36 which fall by gravity through a hopper 39, drum 38, hopper 37 to a position between consolidatry rolls 40, 42. From the rolls the continuous length formed may pass to a winding drum 53 or may be sheared by a cutter 44 into suitable lengths. The shearing cutters which are shown in Fig. 3 have saw teeth 28 and one section 34 is arranged with a cut out part 32 for the part 33 of the other section 34 to be positioned. The length of material may be passed through rolls heated by electric current and in Fig. 6 is shown the passage between rollers 57 connected to a transformer 58 the length 55 of wire forming the electrode of an electric furnace 56, having a slag outlet at 59 and an exit 60 for the product, which passes a cooling chamber 61 and thereby by rolls 64-68 to a wire drawing machine 51 and winding reel 53. Cutters 44 may be provided.

Title: An improved kinematograph intermittent feed mechanism
IPC: G03B1/22
Filed: 1948-07-26
Abstract: 669,639. Kinematograph apparatus. COUTANT, A. C., and MATHOT, J. July 26, 1948, No. 19904/48. Class 97 (i). In an intermittent feed mechanism having at least one reciprocating pawl, spring urged to engage the film perforations and trail over the film on the return stroke, the return stroke is prolonged until the pawl almost, but not quite, reaches the perforation beyond that which,it is intended to engage on the next feed stroke. In one form, for substandard film with one perforation per frame, the claw is carried on a carriage reciprocated parallel to the film through an amplitude nearly twice the frame height. In the form shown in Fig. 2, the film passes round the drum 13 containing the pawl 2 urged outwards by the spring 5. For film with four perforations per frame the pawl amplitude is increased to nearly a quarter greater than the frame height (arc ef as compared with arc cd). A pin 11 on a uniformly rotating disc engages a slot in a lever 9 pivoted at 10, in which slot is also engaged the pin 12 on the drum 13. The feed stroke of the pawl thus corresponds to the rotation of the pin through the arc hij, less than half its rotation.

Preferably the apparatus uses reflected light to determine the degree of oxygenation of blood by applying a probe to the skin. A xenon lamp forms light source 12 which transmits light along light guide 14a to an annular surface in probe 16. The reflected light is transmitted through a second guide 14b to optical apparatus 20 which consists of a focussing lens 26 a rotating filter wheel 24 and a photo-multiplier detector 28. Three or more filters 26 can be used in the wheel 24 and by means of switch 32 the intensity of light from each filter is separated and passes as signals S1, S2, S3 to integrator 38 which integrates the signals over an adjustably selectable time. The signals are paired and subtracted to give (S1-S2) and (S3-S2) and these resultant signals #1 and #2 respectively are operated on by factors representing the motor coefficient of extinction of the component substance. After a further subtraction stage 46, 47 the outputs are divided at 48 and the quotient signal operates meter 50 which indicates the concentration of the component substances. The apparatus may be supplemented to measure the product c.d where c is the concentration and d the length of the light path. The supplementary apparatus comprises three further filters on rotating plate 24 and requires that switches 62, 66 are closed and switch 60 opened. When the log of the quotient of the differences of the intensities of the received signals (S4, S5, S6) has been taken the value of the product is displayed on meter 74.
