Title: Improvements in or relating to Electromechanical Resonators
IPC: H03H9/50
Filed: 1967-07-13
Abstract: 1,198,326. Electromechanical filters. HB ENGINEERING CORP. 13 July, 1967 [15 July, 1966], No. 32351/67. Heading H3U. An H -shaped resonator comprises two massive limbs 12, 14 connected mid-way along their length by a relatively flexible limb 16. Input and output piezoelectric transducers 22 are situated, respectively, on the upper and lower surfaces of the limb 16 and the resonator is pivotally supported on the nodal axes 20 of the limbs 12, 14 by arms 42 upstanding from a base 40. As shown in Fig. 3, flexure of the limb 16 between the positions A and E by the upper transducer 22 causes pivotal movement of the limbs 12, 14 about the axes 20, these limbs pivoting in opposite directions to each other between the positions B and F. Plugs 38 which may be adjustably positioned in bores 36 permit the resonant frequency to be adjusted. Electrical methods of varying the resonant frequency employing auxiliary piezoelectric transducers or electromagnets are described with reference to Figs. 5, 6 (not shown).

Title: Carbon arc lamp with automatic carbon advance
IPC: H05B31/00
Filed: 1959-09-25
Abstract: 894,646. Automatic control systems for arc lamps. BAUER G.m.b.H., E. Sept. 25, 1959 [Sept. 27, 1958], No. 32600/59. Class 38 (4). [Also in Group XL (a)] An automatic control-system for a carbon arc lamp comprises a first control means for advancing the positive carbon in response to the position of the arc, a second control means for advancing the negative carbon in response to the voltage across the arc, the two means being so interconnected that the second control means is disabled whilst the first system is operative. An arc is struck between carbons 3, 5 by manual means whereupon relay coil 101 is energized to close contact 102. The field winding 111 of the carbon advance motor is thus energized directly from positive line 98, the armature 107 of this motor being supplied from the same line over resistors 105, 106. Thereupon the motor rotates very slowly, the positive carbon 3 then being advanced at a very slow rate whilst move ment of the negative carbon 5 is prevented by an electromagnetic lock 65 energized over contact 139 of a relay 136. Under these conditions the advance of the positive carbon does not fully compensate for the burning away of the carbon. At some point the light rays from the arc affect a photo-resistor 84 which becomes conductive to energize a relay coil 90 whereupon contact 92 changes over from contact 94 to contact 93. The field 111 is now supplied over resistor 109, causing field weakening, and resistor 105 is removed from the circuit of the armature 107. The motor now runs at a high speed to quickly advance the positive carbon until the light rays from the arc no longer impinge on the photo resistor 84 which then becomes non-conductive to de-energize relay coil 90 and the contact 92 returns to its original position. Whilst relay coil 90 is energized no movement of the negative carbon is possible since relay 136 cannot be energized under this condition. When relay coil 90 is de-energized should the arc length, and hence arc voltage, become too large sufficient voltage will appear at the points 125, 127, a sensitive relay coil 131 is energized to close contact 138 to energize the relay 136 to open its contact 139 thus deenergizing the lock 65 whereupon the motor is able to slowly advance the negative carbon until the arc voltage is returned to normal. Relay coil 131 is then de-energized and the lock 65 reapplied. Relay 121 protects the sensitive relay 131 against excess voltage. Resistors 116, 117 are oppositely temperature-sensitive and serve to prevent operation of the relays controlling the advance of the negative carbon when the arc lamp is cold.

Abstract: 1,274,724. Polymerizing olefins. VEBACHEMIE A.G. 27 June, 1969 [2 July, 1968], No. 32642/69. Heading C3P. Polyolefin powders are prepared by a process which comprises polymerizing a C 2-4  α-olefin with a catalyst comprising a compound of a Group IV, V or VI transition metal in an oxidation state lower than the maximum and an organo compound of a Group Ia, IIa or IIIb metal, the catalyst being applied to a finely divided polyolefin support in the form of substantially lenticular or spherical particles, and recovering a finely divided, free flowing product of average particle size substantially larger than that of the finely divided support. The catalyst may be prepared by reducing a transition metal compound with an organometallic compound in the presence of the support, and activating the product with further organometallic compound. The support may be powdered polyethylene or polypropylene. The polymerization may be effected in a liquid hydrocarbon diluent, or in the gaseous phase in a fluidized bed. In examples a mixture of vanadyl trichloride and n-propyl titanate is reduced with diethyl aluminium chloride in an aliphatic hydrocarbon solvent in the presence of polyethylene powder and the product (1) used with aluminium triethyl to polymerize ethylene in an aliphatic hydrocarbon diluent in the presence of hydrogen and (2) used with aluminium triisobutyl for the polymerization of ethylene in a fluidized bed.

Abstract: 385,096. Centrifugal pumps. WEIR, Ltd., G. & J. and HILLIER, H., Holm Foundry, Cathcart, Glasgow. Dec. 5, 1931, No. 33735. [Class 110 (i).] A device for bringing into operation an auxiliary pump 3 comprises a piston 17 which is exposed at its upper end to the discharge pressure of the main pump and on its lower to a spring pressure 12. On the discharge pressure of the main pump falling below a certain valve the piston is forced upwards and carries with it a valve 4 which admits steam to the driving turbine 2 of the auxiliary pump 3. The discharge side of the auxiliary pump is connected to the lower end of the piston 17 and the discharge pressure acting in addition to the spring pressure maintains the piston in the raised position thus keeping steam supplied to the turbine 2 until it is cut off by hand. The piston may be replaced by a diaphragm 29, Fig. 3, which lifts a needle valve 30. On the needle valve lifting and allowing water to pass, a valve 31 in the steam supply pipe is operated by a diaphragm 32. Where the pump is driven by an electric motor the piston 17 is connected to an electric switch.
