Patent GB-474252-A (GB)
Title: A method of treating the cylinders, pistons, piston rings, valves, valve seats, valve spindles, valve stem guides and the like of internal combustion engines with a view to minimizing friction and/or minimizing wear
IPC: F16J9/26
Filed: 1936-05-16
Abstract: Wearing parts of internal-combustion engines, which are subjected to high temperature, are coated with a composition containing graphite, shellac or gum, water, and borax or other solvent for the shellac or gum, and are then subjected to heat treatment to render the composition unaffected by petrol or oil, the surplus composition finally being removed.  A smooth surface is thus obtained which will withstand considerable wear at the high temperature of the engine gases, and, in the case of relatively moving parts, will effect the lubrication thereof. Heat treatment at 300 DEG  F., for 24 hours is specified.  A small amount of potassium bichromate may be added to the composition to reduce "pitting," and several coats may be applied, as by brushing or spraying, each coat being allowed to dry before the next is applied.

Title: mprovements in or relating to the production of articles of synthetic plastics material
IPC: C08F2/52
Filed: 1964-04-06
Abstract: 1,048,194. Moulding lustrous &c. articles. H. HUNSDIECKER. April 6, 1964 [April 4, 1963], No. 14024/64. Heading B5A. Lustrous or decorative plastics articles are formed orienting colouring pigment particles in a transparent liquid resin, contained in a non- electrically conductive mould, by means of 3-dimensionally curved lines of force emanating from charged conductors or condensers placed against the mould, the resin being subsequently hardened. In one example (see Fig. 1), the pigment particles are oriented in a collapsible glass mould comprising side walls 2, 3, 4, 5 and base 1, by means of charged conducting wires embedded in a dielectric sheet 6 positioned against wall 3 on pins 9. Where the lines of force from conductors 7 enter the material through wall 3 the particles are oriented approximately at right-angles to the surface of the material and such regions consequently appear clear when viewed. Conversely to the regions 10 of the material, i.e. away from the conductors, the particles are oriental approximately parallel to the surface and thus said regions appear lustrous. By suitable charging and distribution of the conductors or condensers any required pattern may be imparted to the material (see Figs. 7a-19, not shown).

Filed: 1953-05-27
Abstract: 725,389. Friction clutches, reversing gearing. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 27, 1953, No. 14747/53. Class 80 (2) Openings are provided in the housing of an electromagnetic friction clutch to facilitate the adjustment of an abutment for a stack of friction plates and the measurement of the air gap between the magnet and its armature. As shown applied to a reversing gear, two drums 27 oppositely rotated from an input shaft 1, Fig. 4, are clutchable selectively to an output shaft 3. The shaft 1 carries a wide pinion 33 meshing with both a gear 31 on one drum 27 and a gear 35 driving, through a shaft 37 and a gear 39, a gear 29 on the other drum 27. Each clutch comprises a series of carbon discs 11, splined to the drum 27 at 41, alternating with a series of steel discs 9 splined at 43 to the output shaft 3. Engaging pressure is applied to each clutch through a thrust race 69 and a tubular member 67 from the armature 65 of an electromagnet 61. To facilitate measurement of the air gap between the armatures 65 and the magnets 61, an opening for the insertion of a feeler is provided in the clutch housing, but is normally covered by a removable plate. Adjustment of the air gap to compensate for wear on the clutch plates is effected by an abutment disc 49 which is screwed into the drum 27. A diametral split 53 in the disc allows it to be expanded, by means of a screw 55 engaging a tapered hole in the split, to lock the disc in position. An aperture 59 allows a wrench to be inserted to slacken the screw 55, after which the input shaft 1 may be rotated until the air gap is of the required dimension.
Patent GB-147765-A (GB)
Abstract: 147,765. Trinks, F. Dec. 4, 1913, [Convention date]'. Adding-apparatus.-In a calculating-machine of the pin-wheel and cam-disk type the settable pins, which may be pivoted for lateral movement or displaceable radially, are adapted to be moved to operative position by means of setting-levers c<1> when turned in one direction and to be restored to normal position on the return movement of said levers. As shown in Figs. 1, 2 the pins d are pivoted at d1 for lateral movement, and the setting-levers c<1>, which are loosely mounted on the shaft b but rotate with the pin wheels a, have projections i, k. The projection i serves to set the pins d in operative position when the lever c<1> is adjusted in the direction of the arrow x, while the projection k on the return movement presses the pins back to inoperative position. Each setting-lever c<1> is held in adjusted position by a toothed sector g thereon engaging a bolt h on the corresponding pin-wheel a. A modification is described in which the setting-levers do not rotate with the pin-wheels a. In this case the setting-levers are pivoted to a hub loosely mounted on the shaft b and are normally held out of operative relation with respect to the pins d by means of a spring (the levers themselves may form the spring). The setting levers are held in adjusted position by a toothed sector on the hub and a bolt on the fixed part of the frame, and by means of teeth or recesses in one side of the slot through which the setting-levers project and which compel the operator to move the setting-levers within reach of the pins d when effecting the setting or restoration thereof. The setting-levers may gear directly or indirectly with numerals wheels to indicate the item set.

Title: Doppler correlation radar system
IPC: G01S7/34
Filed: 1970-03-26
Abstract: 1300157 Doppler radar RCA CORPORATION 26 March 1970 [28 March 1969] 14830/70 Heading H4D A Doppler radar has a CW transmitted signal phase modulated in accordance with a binary code and in which the received echoes are mixed with contemporary transmitted signals, wherein the binary code is a group of N bits including a sub-group of successive bits # N/2 and only the sub-group is correlated against the contempoary mixed output to provide an audio signal indicating a moving target which varies directly with the echo amplitude and the range of the target. An n bit shift register 22 supplies its (n - 1)th and nth bits to an exclusive -NOR multiplier 23, whose output is thus a pseudorandom code of 2<SP>n</SP> - 1 bits cycle duration. Each bit of the register is fed to an AND gate 64 which produces an output pulse once every code cycle. This pulse changes the state of a bi-stable 68 which enables an AND gate 72 to which is supplied the pseudo-random code. Thus the output of the gate 72 is a code formed by alternate cycles of the pseudo-random code interspaced with equal length uncoded periods. This code is used to phase-modulate a CW signal which passes through a circulator 14 to the aerial 72. Echoes from a target are mixed with leakage from the transmitted signal to provide a signal delayed by the transit time to and from the target. The nth output of the register 22 is fed to the input of an m bit register 62. All of the n + m bits of the two registers are available to a tap switch 80. Each bit of the registers corresponds to the contemporary modulating signal delayed by an amount corresponding to a specific range bin. The output of multiplier 78 is thus the product of the contemporary modulating signal and the delayed modulating signal, this signal being fed to correlator 74. The other input is the product of the contemporary modulating signal and the received signal. Thus when the tap switch delay equals the target delay the output of the correlator is a maximum and the presence of a target is indicated by a meter, the range being indicated by switch 80. A second target indication signal is generated by a second correlator 76, which has an input from the mixer output and from the AND gate 72. An OR agte 70 connected to bi-stable 68 and AND gate 64 provides a blanking signal to the correlator thereby selecting the sub-group of bits from the modulating code, the sub-group being the second to seventh bits of the pseudo-random half of the code. The correlator produces a signal which increases in amplitude with increasing range and which is fed to earphones. Thus when the operator hears a signal indicating a target, he operates switch 80 until meter 82 indicates the range bin which contains the target.

May 20, 1931, No. 14889. Convention date, May 21, 1930. [Class 87 (ii).] Bodies, such as gearwheel blanks, comprising a number of dissimilar elements formed from spinnable textile fibres treated with an adhesive binder, such as phenolic condensation product, are heated, preferably in damp air, to soften the adhesive, compressed in a mould to form a preform without curing the binder, and then pressed and heated to cure the binder and produce the final shape. The wheel elements 5 .. 8 are fitted upon a support-ring 3 into a perforated container I in which they are heated, preferably in a steamy atmosphere, the steam providing the heat or supplying the moisture to an electrical oven through which the container slowly passes. The binder is thus softened and the elements adhere together but not to the container. The ring 3 is then removed and the container inserted through a side opening 14 into a groove 15 on a mould 9, the elements being forced from the container and compressed at a pressure of about 2000 lbs. per sq. in. between dies 10, 12 to produce a preform. The preform is then warmed to remove moisture and soften the adhesive and is finally steam-heated and compressed in another mould to cure the binder and produce the final shape. Fig. 6 shows the manner in which the binder-treated constituent wheel-elements are arranged in relation to the perforated container 22, in which the preliminary heating takes place, when the web and hub are of loose cotton 23 and the rim of rings 24 of woven material. The container is removed while the preforming operation is taking place.
