Title: Improvements in or relating to push rods and methods of making the same
IPC: F01L1/14
Filed: 1958-10-29
Abstract: 838,899. Making valve push rods; force fits. BUNDY TUBING CO. Oct. 29, 1958 [Nov. 8, 1957], No. 34605/58. Classes 83 (2) and 83 (4). [Also in Group XXVII] In a method of making a push rod e.g. a valve push rod an end portion of the wall of a tube 30 is formed with at least three circumferentially spaced axially and inwardly extending projections 36 between which is secured on a predetermined centre an insert 40, a part 42 of which projects out of the tube for operative engagement with other mechanism. A tubular valve push-rod 10 having end pieces 27 is operated from a cam-shaft 14 and a recessed valvelifter 11, the upper end of the rod 10 engaging a recessed arm 21 of a valve-actuating rocker 12. The tube 30 is made by transversely rolling flat strip to tubular form and welding or brazing the opposed edges together. The welding may be by electric resistance or electric arc. A tube having a two-ply wall may be made by rolling strip through 720 degrees and brazing the interfaces. The projections 36 may be short compared with the length of the tube or may extend the full length in which case long lengths of tubular stock are fluted prior to cutting to rod length. The projection-forming flutes 37 may also be formed by pressing a die over the end of the tube. On insertion of the part 40 of the end piece 27 the projections may be pressed out slightly but still support the insert clear of the internal weld flash. The insert may additionally be secured by a spot weld 44. In a modification the insert may have a projecting portion with a recess for engagement with other mechanism. U.S.A. Specification 2,292,810 is referred to.
Patent GB-768047-A (GB)
Title: Improvements in and relating to control systems for electric power networks
IPC: H02J3/46
Filed: 1954-11-30
Abstract: 768,047. Automatic control systems for power supply networks. GENERAL ELECTRIC CO. Nov. 30, 1954 [Nov. 30, 1953], No. 34699/54. Class 38 (4). In a power supply system in which one group of power stations, controlled by a central station, exports power by a tie line to a second group of power stations controlled by their central station, and in which both groups additionally supply their own local loads, the generators of the individual stations of each group are automatically controlled to maintain the tie line load constant by apparatus at each central station which compares the system frequency with a frequency standard and compares the tie line load with a preset value, adds the error signals algebraically, and transmits the resultant (modified to effect a preset load sharing programme) to the individual stations of the group to control the governor settings of the generators. As viewed from the exporting central station, a rise in system frequency accompanied by a rise in tie line power indicates a reduction in local load; the two signals are additive and correction is made as above. However, a rise in frequency accompanied by a drop in tie line power indicates a reduction in load on the remote group ; the two signals are then arranged to cancel and no correction is made to the local generators. Increases in local load are similarly distinguished from increases in remote load. A standard frequency oscillator 10 supplies a frequency comparator 11 to which the system supply is also connected. The output is stated to be a rotating shaft 14 which is one input to a differential 14. The other input is a shaft 18 of a power comparator 16 which it is stated compares the tie line load with a preset reference. The differential is arranged to multiply either the frequency error signal or the load error signal by an empirical constant so that the two signals just cancel when the remote area load changes. The output of the differential is applied to a gear box 21 which has several output shafts, e.g. 3, with different gear ratios, the gear ratios being selected to enable stations with different rates of response to be controlled. Each shaft drives a selsyn generator so as to produce an A.C. output signal, and these signals are connected to selector switches (one per station: only one, 34, being shown). Each switch arm connects to a load proportioner 38 which consists of a selsyn driven by a variable speed motor so that the share of load to be taken by each station of the group can be pre-set. The final signal is sent via carrier current transmitters, e.g. 44, to receivers, e.g. 45, at each station of the group. The demodulated signal is applied to a series of electronic positioning units, one per generator, to control the individual turbine governors.

Title: Improvements in or relating to process of polymerizing 3,3-bis (chloromethyl) oxetane
IPC: C08G65/18
Filed: 1958-10-31
Abstract: High molecular weight polymers of 3,3-bis (chloromethyl) oxetane are produced by continuously feeding the monomer and catalyst into the upper end of a polymerization zone containing a mass of such material being polymerized, removing excess exothermic heat of polymerization by boiling of the monomer as it descends into the mass, maintaining a body of polymer at the bottom of the zone to effect complete polymerization therein, and withdrawing substantially completely polymerized product from the bottom of the zone at a rate to maintain a substantially constant mass of material being polymerized.  A volatile solvent may be added to the system to provide improved temperature control, preferably with a boiling point between 150 DEG -175 DEG C., e.g. heptane, decane, dodecane, carbon tetrachloride, tetrachloro-ethane and trifluoro-1, 1, 2-tribromoethane.  The catalyst may be triethylaluminium or other aluminium alkyl, alkoxide or chloride catalysts as described in Specifications 819,407 and 832,283 and U.S.A. Specification 2,905,647.  Apparatus for carrying out the process is described in detail.  Peak reactor temperatures of from about 205 DEG  to 232 DEG C. are obtained, with temperatures of polymer at the end of the zone at 180 DEG  to 250 DEG C.  The products may be separated by quenching in a non-solvent or by cooling, grinding and washing.  They have specific viscosities of between 0,3 and 4,0 measured as a 1% solution in cyclohexanone at 50 DEG C., i.e. molecular weights in excess of 10,000 are obtained. They may be moulded or extended to form films, filaments, sheeting, strip, tubing; calendered to coat paper or fabric; and laminated to form counter tops, industrial board, &c.

Title: Apparatus for determining the direction of incident sound
IPC: H04R1/40
Filed: 1969-07-11
Abstract: 1,261,098. Direction-finding systems. FRIED KRUPP G.m.b.H. 11 July, 1969 [12 July, 1968], No. 35128/69. Heading H4D. In a system for determining the angle of incidence α of sound waves W relative to a reference axis of a circular array of receiving transducers, direction-indicating voltages derived from the differential voltages of diametrically opposed transducers are compensated for disturbing components, which are a function of 3α, 5α &c. and arise if the sound wavelength is comparable to the array dimensions, by providing at least one further similar array angularly offset from the first by #/(2k+1) (where k is an integer) and by summing the outputs of transducers of the first array with the outputs -of corresponding transducers of the further array. As shown, the first array N comprises transducers 1N, 2N, 3N, 4N. An X voltage and Y voltage whose amplitudes are a function of cosα and sinα, respectively, are derived from transducer pairs in array N. Similarly, voltages X<SP>1</SP> and Y<SP>1</SP> are derived from array K, which is offset by #=#/3, and summed -with the X and Y voltages, respectively. It is shown that disturbing X, Y components which are functions of 3α are thereby cancelled. Further offset arrays may be used to cancel less significant disturbing components which are functions of higher multiples of α: thus an array offset by # = #/6 +#/5 (i.e.#/5 from a reference axis of the combined K and N arrays) will cancel 5α components. The compensated X -and Y voltages, together an "omnidirectional" voltage Z which is the sum of -all transducer voltages, may be used to give an unambiguous cathode-ray tube indication of sound wave direction. The transducers may be parallel connected instead of series-connected, for summing currents rather than voltages.
