Filed: 1929-07-19
Abstract: 338,505. Triggs, W. W., (Kalif Corporation). July 19, 1929. Casting - machines ; moulds. - To facilitate flow of heat from the friction surface of a journal bearing, the bearing element 12 is laterally surrounded by a frame member 10 of high tensile material constructed so that a substantial area (one quarter or more) of the upper surface of the bearing element contacts with the load transmitting surface. The bearing element which may be composed of a copper-lead alloy is secured to the frame by brazing and engagement in notches 10<1>. The bearing is formed by running molten alloy into a sand mould 14 containing the frame 10, which has been previously plated with a film of copper. Before the introduction of the alloy, a dry, moisture absorbing, and. preferably, -non- oxidizing gas, such as nitrogen, is passed from a source 18 to a tube 22 surrounded by an electric heater 25 and finally through the mould. In lieu of nitrogen, the gas obtained by burning hydrogen free producer gas with a slight deficiency of air may be employed. On the withdrawal of the gas flow, molten alloy in excess of the quantity required for the bearing element is run in at 15.

Title: Planographic printing plate and method for preparing same
Filed: 1961-06-20
Abstract: A metal base such as Al, steel, Zn, Mg, Cr or Cu is treated with an aqueous solution of a potassium titanium hexahalide, preferably K2TiF6 in a concentration of 0.1% to saturation, to form a hydrophilic coating prior to coating with a light-sensitive compound capable of becoming water insoluble and ink receptive upon exposure to light to form a planographic printing plate.  The metal base is first alkali degreased, acid etched, desmutted and then activated with phosphoric, chromic, nitric, sulphuric, or oxalic acid.  After treatment in the K2TiF6 solution at 90-180 DEG F. the coating is given a hot water rinse and then hardened in a 0.1-5% solution of citric acid or tartaric acid at 50-100  DEG F.  The treated base is then coated with a light-sensitive compound such as albumen bichromate or a diazo resin such as the condensation product of paraformaldehyde and paradiazophenylamine or the furfural acetone concentration products or the cinnamyl compound antioxidant such as a 0.01-0.1% aqueous solution of hydroquinone may be added to the hydrophilic layer prior to the diazo treatment.

Abstract: 580,032. Dry shavers; making dry shavers. PHILLIPS, H. Nov. 13, 1944, Nos. 22370/44 and 7559/45. [Class 131] [Also in Group XXII] A dry .shaver includes a guard formed by closely spaced arcuate members b ground on their inner faces at b' to provide slots of the necessary width for the entry of hair to be cut. The members b are made by winding a wire b round a circular former and welding it to the strips e arranged peripherally in pairs. The strips e are separated in pairs and the wire between the strips ground, bent as at b' and secured to the base a. A spring clip f is inserted to add rigidity and protective pieces hold the assembly in place. The reciprocating cutter c is arranged inside the guard so that its blades d are substantially tangential to the inner surfaces of the guard at their point of contact and is made by imbedding a helical coil of steel d with chamfered edges in a base c or by securing flat strips of steel d to a rectangular base c which is subsequently cut in two at c' as shown in Fig. 8. The guard and cutter may be made by impressing or machine-cutting a series of semicircular ridges on a plate and grinding the middle portion on the faces which will later be brought together until the spaces between adjacent ridges are of the required width.

Title: Communications systems hving automatic line transfer systems

Filed: 1974-05-21
Abstract: 1447007 By-passing failed repeaters VIDAR CORP 21 May 1974 [1 June 1973] 22683/74 Heading H4R If a line section fails it is by-passed by a section of reserve line Pα and connected 13 to the preceding reserve line section for fault interrogation from a command office 1. A pulse every sixth time slot is sent along reserve line Pα by a unit "6425" at the command office and if there is no by-pass the pulses are looped back by the terminating office 4 for detection at the command office. PCM data on the working lines a-f is sensed by units "6415" at each office to detect when pulses are not of alternating polarity, contain 14 zeroes or exceed 1 ms. corresponding to a fault condition. The priority status of the failed line is assessed, a lamp light and a transfer unit activated to change over switches at the downstream office (in this case office 3) thereby connecting the outgoing side to the corresponding end of the reserve line Pα. A loop 16 is also completed. The absence of a fault interrogation code and the presence of a fault condition is used to signal back to the preceding office 2, by increasing the error rate of the data stream, to cause that office to connect to the other end of the reserve section Pα and to connect the failed section to the preceding reserve line section. The increased error rate data stream is connected back to proper form in the preceding office to prevent indicating a non-existent fault in preceding sections. A test set may be plugged in to the "6425" unit at the command office to interrogate the nature and location of the fault or the faulty office section may transmit back a characteristic code. The command office includes a data connector as above which is disabled during fault interrogation. "6425" Units in other offices detect the absence of the sixth time slot code to indicate that a line transfer or a fault in the reserve line has occurred. The reserve line is sensed for data errors as for working lines and the controlling unit "6425" generates an eighth time slot code to indicate that a line transfer has occurred. If a reserve line fails all transfers to it are released either to their original working line or to a second reserve. Minor and major alarms operate if the first or the second reserve respectively fails. A failed line is tested before release and if good for 10 sees. the release is effected provided a manual or automatic reset switch is operative. A reset code of every second time slot permits remote resetting of all affected units. The resetting of reserve lines is effected by units "6425" at the downstream end of each reserve line section.

The pivots and window locking devices (not shown) are located between the two parallel runs. The runs may be on the external peripheral surface of the sash to make edge contact with the curved internal peripheral surface of the frame.

One face of the flange 10 of the strip is located in the median perpendicular plane of the beading 11 and shallower flanges 12 on either side are spaced from the flange 10 by a distance equal to the thickness of a flange so that when the strips are reversed relatively and the flanges arranged end to end, the flanges can be interleaved with the median planes of the beading coinciding when the beadings are in the grooves 8.
