Title: Improvements in abrasive tools
IPC: B24D7/02
Filed: 1942-06-25
Abstract: 557,194. Moulding abrasive tools. TEAGUE, E. D., and NORTON GRINDING WHEEL CO., Ltd. June 25, 1942, No. 8737. [Class 87 (ii)] [Also in Group XXIII] In moulding abrasive tools having diamond or other abrasive bounded by a resinoid or like bond, a metallic powder is incorporated in the abrasive-bearing bond to form a localized wear-resisting skin. As shown, a cup wheel comprises a skin 3 united to the outer perimeter of a layer 2 of resinoid-plus-diamond powder formed on the face of a non-abrasive-containing form 1. The Fig. shows the assembly before the parts 2, 3 have been compressed. The invention may be applied to disc wheels carrying abrasive on the periphery or on the sides, or to honing sticks or stones. In making the wheel shown, the pre-moulded form 1 is inserted, together with a bottom plate 6 and arbor 7, into a mould 5. The exposed inner surface of the mould 5 is smeared with grease or with an adhesive such as glue or synthetic resin solution, the assembly 1-6-7 is removed and the preform 1 is cleansed of grease &c. Electrolytic iron powder of 300 mesh is spread over the grease &c., the mould being rolled on its circumference to promote even distribution. The loaded grease &c. is then trimmed to leave a skin 3. The assembly 1-6-7 is replaced, a hub member 8 is placed in position, diamond-resinoid mixture 2 is filled in to a depth 1/32-in. below the upper edge of the skin 3, and the mixture 2 and skin 3 are pressed by a member 4. The bond may be cured while the wheel is still in the mould, or after removal from the mould. It is found that the metal powder permeates the layer 2. If the metal-loaded grease &c. has spread over the top surface of the layer 2, the area affected may be ground. The form 1 may be moulded at the same time as the diamond-resinoid mixture is moulded. The metallic powder may be tin or copper. The bond may be shellac or rubber.

Title: Process and apparatus for producing continuous sheet of biaxially oriented organic polymer
IPC: B29C55/14
Filed: 1944-05-09
Abstract: <PICT:0585164/IV/1> <PICT:0585164/IV/2> <PICT:0585164/IV/3> A solvent-free organic polymer such as polystyrene is continuously extruded at a raised temperature in the form of a ribbon, cooled to a temperature at which it may be oriented by stretching, and stretched first longitudinally only and then transversely.  The transverse stress is applied by gripping and pulling apart the edges of the elongated portion of the ribbon, and the stress is maintained while reducing the temperature to below the temperature at which internal stresses of the polymer are relieved.  Apparatus for carrying out the process comprises a heated stuffer S, an extrusion die D, rolls C which cool the extruded film, a re-heating oven O with heaters H, and grippers g which are driven at such a speed as to stretch the film longitudinally, e.g. at a linear speed four times that of the rolls C.  The grippers are simultaneously moved outwardly by means of the cams 107 so as to stretch the film transversely.  The grippers are moved by means of endless chains, and the claws of the grippers are operated by means of cams 68a and 68b in order to grip and release the edges of the film, respectively.  In order to compensate for transverse variations in the thickness of the film, the thicker portions of the film are re-heated, prior to stretching, to a lesser extent than the thinner portions, as shown in Figs. 3 and 4, in which 41, 42 and 43 are insulators.

Abstract: 1,137,863. Crimping yarns; forming yarn packages. KLINGER MFG. CO. Ltd. 28 Jan., 1966 [2 March, 1965], No. 8891/65. Headings DID and D1F. Yarn 1, crimped in a stuffer box crimper 15, is wound by a roller 22 into a package 20 under such tension, imparted by a tension device 17, that the yarn is straightened and the bulkiness temporarily removed: thus the formation of the package is facilitated and yarn speed of over 1000 ft/min may be obtained: the subsequent unwinding of the package is also improved. Tension device: yarn guide. The tension device comprises relatively movable combs between the teeth of which the yarn passes in serpentine manner. One of the combs is rotatably mounted and biassed by a weight so that should the yarn tension fall the weight moves the rotatable comb to increase the path of the yarn over the teeth and so restore the original tension. The weight is attached to its comb by rubber, rubber-like or spring means so that sudden tensions caused by abrupt movement of the weight are damped. At the entry end of the tension device a guide surrounded by an annular shield is provided to keep the incoming yarn out of contact with the teeth of the comb. The comb teeth adjacent the yarn entry end of the tension device are lengthened to prevent the yarn coming out of contact therewith.

Abstract: 1,207,551. Teaching warfare. AAI CORP. 26 Feb., 1968 [28 Feb., 1967 (2)], No. 9273/68. Heading F3C. [Also in Division H4] An arrangement for teaching and training in gunnery comprises a weapon having a barrel 39 and being mounted on a vehicle, a photoscope 11 being mounted in the bore of the barrel. A transmitter is associated with the trigger of the weapon such that on actuation of the trigger a signal. is transmitted omnidirectionally. This signal is detected at a target and causes an infrared radiation device 27 on the target to radiate a signal. If the radiated infra-red signal falls on the radiation sensitive part of the photoscope, the weapon has been aimed correctly and a hit is recorded. The hit signal may be transmitted back to the target (Fig. 1, not shown). In the construction shown, the photoscope comprises a photodiode 43 having a radiation sensitive surface 49, radiation being focused on to the surface 49 by a lens 41. A mask 51 is interposed between the lens 41 and photodiode 43. To increase the range of usefulness of a photoscope, two lenses may be mounted, preferably one within an axial bore of the other, each lens focusing radiation on to separate photodiodes (Figs. 9, 10, 11, not shown). As a " target hit " signal from a photodiode is very small, an amplifier is located adjacent each photodiode in the photoscope housing, the signal from the amplifier being passed to a Schmidt trigger and thence to an OR gate. The signal is then passed through a cable to a modulator and the transmitter in the vehicle. The photoscope is centred in the barrel of the weapon by a bevelled ring attached to the forward end of the photoscope and engaging in the muzzle of the barrel (Figs. 3, 4, 10, 11, not shown). The photoscope is supported at its rearward end by a tensioned cable (Fig. 10, not shown) or a tensioned cable and plastics shoe combination (Figs. 3, 4, not shown). The sensitivity of the radiation sensitive surface of the photoscope may decrease from the centre of the surface.

[Class 40 (iv)] [Also in Group XXXVI] in an arrangement for amplifying or reproducing direct current in a circuit 1 by means of a transductor 2, the alternating current of which is rectified by a rectifier 5, the direct current circuit 1 is coupled to the output circuit by a transformer 3 in order to balance out irregularities caused by imperfections in the transductor and rectifier. These irregularities occur mainly when the transductor is saturated, and the transformer 3 should, therefore, not be saturated at such times. To ensure this, an additional winding fed with constant direct current may be provided on the transductor or transformer or both, or the transformer may be constructed by suitable choice of turns or core material or otherwise so that it requires greater current for saturation than does the transductor. The output current is fed to a measuring instrument or control apparatus 6. Specification 558,269 is referred to.
