Title: Improvements in or relating to high-frequency pulse producing apparatus
IPC: H03K3/78
Filed: 1946-07-08
Abstract: 626,709. Wave-guides. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 8, 1946, No. 20395. Convention date, March 4, 1944. [Class 40 (v)] Ultra high frequency energy is fed to each of a number of wave-guides in turn for a short period, the propagation times of the waveguides being such that the energy fed to a collecting wave-guide from all the guides coincides in time to give a pulse of duration equal to the time for which each guide is connected to the source of high frequency energy. Fig. 1 shows a radiating element A, surrounded by a cylindrical shield provided with a slit and rotating at a speed equal to the pulse repetition frequency. A fixed shield surrounds the rotating shield, and has a number of slits, similar to that in the inner shield and forming the ends of wave-guides L<1> ... The waveguides L<1> ... are connected through delay guides, which may be rectangular guides of height approaching #/2 or with a dielectric other than air, to a common collecting guide. The effective lengths of the delay guides are such that the energy transmitted by all the guides L<1> ... arrives in the collecting guide at the same time to give a short, high amplitude pulse. In a modification, Fig. 3, the radiating element A feeds resonators R<1>, R<2> ..., which are traversed by a discharge tube K. Each resonator R<1> ... is tuned for a particular voltage applied to the discharge tube K, when high frequency energy is fed through a delay guide L<1> to a collecting guide G. Each resonator R<1> is tuned in turn by applying a series of pulses of duration equal to that of the desired pulse and modulated at the pulse repetition frequency to the discharge tube K.

Abstract: 1,249,417. Sealing ceramic to ceramic and to metal. GENERAL ELECTRIC CO. Ltd. 22 April, 1970 [22 April, 1969], No. 20466/69. Heading B3V. [Also in Division C7] A ceramic-to-ceramic, or to metal, seal between substantially thermally-matched materials, e.g. in electron valves or sodium vapour discharge lamps, comprises a layer of an active alloy sealing material containing a finely-divided dispersion of zirconium oxide not greater than 60% by volume in any part of the layer. The ceramic may be alumina, magnesium oxide or magnesium spinel, and the metal Nb, Ti, Ta, W, Mo or Rh or an alloy of two or more of these. Alternatively, one of the ceramic materials in a ceramic-to-ceramic seal may be a boride, carbide, nitride or silicide of a refractory metal. The sealing layer may be introduced between the surfaces to be sealed as an alloy, or in the form of shims of the separate metals including Zr, zirconium oxide being formed by reaction between the Zr and the refractory oxide of the ceramic. If Zr is not used as an active metal in the sealing layer, a zirconium oxide dispersion is incorporated in the layer before it is inserted and another active metal is used. Added to this initial composition for the sealing layer may be Ni, Fe, Cu, Co, Mn or Cr, in the percentages listed, to bring the m.p. into the range 950- 1350‹ C.

Title: Injection moulding
IPC: B29C37/00
Filed: 1974-05-09
Abstract: 1449728 Injection moulding control system CINCINNATI MILACRON Inc 9 May 1974 [10 May 1973] 20484/74 Heading B5A [Also in Division G3] A control system for controlling the postinjection holding pressure of an injection moulding machine having a mould cavity 22 and a plasticator 11 comprises a transducer 32 for providing a signal representative of the mould cavity pressure, an integrating circuit 34 for integrating the first signal over a predetermined time interval (t 1 -t 2 , Fig. 2), a reference source 41 for providing a second signal representative of a desired holding pressure, a comparator 40 for comparing the second signal with the integrated first signal to produce an error signal and modulating means for causing the holding pressure applied by the plasticator 11 to the mould cavity in the next machine cycle to be varied in accordance with the error signal thereby to reduce the deviation of the holding pressure from the desired pressure, The modulating means may comprise an electrically modulated pressure control valve 30 which is adjusted in response to the error signal received by the valve driver 28 and which is connected by a solenoid valve 31 to the fluid pressure line 17 of the piston 15/cylinder 14 for driving the plasticator forward to inject a shot. The modulating means may include a summing circuit 44 which combines the error signal with a third, holding pressure, reference signal derived from a sample and memory circuit 45. This memory is loaded from an injection pressure reference source 46 prior to or during the first cycle of operation but thereafter the reference signal in the memory 45 is replaced at each cycle by the corrected error signal issuing from the summing circuit 44. The integration of the first signal may not be commenced until the pressure in the mould cavity exceeds a predetermined value, e.g. 100 p.s.i. determined by a reference source 36 (see t 0  of Fig. 2, not shown). This nominal value ensures that the timer 37 is not operated if a blockage occurs in the nozzle or sprue bore. The switch from injection pressure to a lower holding pressure is effected by a mechanism 25 which supplies a signal representative of the plasticizing screw's position to a switching control 26 where it is compared to a reference position signal 27. When the signals coincide a gating signal is transmitted to the valve driver 28, valve 30, a cycle controller 29 and the solenoid valve 31.

Title: Automatic charging device for tunnel ovens
IPC: A21B3/07
Filed: 1933-07-21
Abstract: 423,103. Bakers' ovens. SPINETTE, V., 20, Rue Camille Simoens, Schaerbeek, Brussels. July 21, 1933, No. 20635. Convention date, July 22, 1932. [Class 51 (ii)] A travelling bakers' oven is charged by a reciprocating carriage 21operated automatically from the oven conveyer 13 and caused to move forwardly against the action of counterweights by the engagement of catches 30 on endless driving chains 22 with bolts 31 on the carriage, the arrangement being such that, when the carriage reaches charging position, the bolts are automatically disengaged and the carriage is returned by the counterweights to initial position. Release of the bolts 31 is effected by a spring-pressed rod 32 which, by engagement with an abutment on the door 15 is moved rearwardly to release a pawl 33 from a ratchet wheel 34 mounted on a hollow shaft 35, the latter being fitted internally with a spring control which causes it to rotate and lift, through a cam device, the bolt 31 clear of the catch 30. This mechanism is reset, during the return travel of the carriage, by the engagement of curved levers 37 mounted on the shaft 35 with fixed tappets 38. Levers 39 are provided by which the bolts may be released, if necessary, by hand. The carriage 21 comprises a table 10 on which rests a cloth 11 having end rods 54, 55 to which are secured cords 56, 57 wound over drums 58 mounted on a hollow shaft 20 encircling the shaft 35. When the carriage reaches charging position the rod 54 is engaged by hook members 62 which keep it stationary during the first part of the return movement so that the cloth 11 passes, as shown in Fig. 5, below the table 10 and feeds the loaves 12, previously placed thereon, to the oven conveyer 13. At the end of the travel of the cloth the rod 54 moves out of engagement with the hooks 62 and the cloth is returned by rotation of the shaft 20 effected by engagement of pulleys mounted thereon with fixed guide rails. Free-wheel devices are incorporated in the mounting of these pulleys so that no rotation of the shaft 20 takes place during the forward travel of the carriage 21. The actuating-shaft 27 for the chains 22 is driven by an electric motor which is switched in, at the appropriate intervals, by peaks on a cam wheel secured to the shaft 65 of the oven conveyer 13, and out, to enable the carriage to return and be reloaded, by a second switch operated by the catches 30 after the bolts 31 have been disengaged therefrom. The oven is provided with a sealed charging chamber having alternately operated doors 15, 16 which are interconnected by link mechanism 46 ... 50 so that when the door 15 is raised, by the engagement of stops 41 on the charging carriage with rollers 42, the door 16 is lowered. Specification 423,102 is referred to.

Title: Improvements in or relating to reverberation apparatus
Inventor: BARRASS ROBERT
IPC: G10K15/12
Filed: 1962-05-30
Abstract: 1,027,521. Reverberation apparatus. PYE Ltd. May 21, 1963 [May 30, 1962], No. 20804/62. Heading H4R. In an apparatus for providing reverberation the input signal is analysed to determine the relative amplitudes of a predetermined number of discrete frequencies, or narrow bands of frequencies, and control signals derived which are representative of the amplitudes of these frequency components, the control signals are then delayed and used to control the amplitudes of similar frequency components produced in the apparatus which are mixed with the original signal and fed to the output. Multiple reverberation effects may be produced by feeding the frequency components produced by the apparatus back into the input of the apparatus. The Figure shows the preferred embodiment in which the input signal after amplification in amplifier 1 and 4 is fed to a plurality of band-pass filters f1, f2 &c., the outputs of which are rectified and applied to a delay circuit RC to provide control signals DC1, DC2 &c. These control signals are used to control the level of frequency components similar to those from which the control signals were derived, the components being selected by band-pass filters f1-f2, f2-f3 &c. from the white noise source 5. The outputs from the amplitude controllers C1, C2 &c. are combined and mixed with the original signal from a volume control circuit 2 and fed to the output amplifier 3. The control signals DC1, DC2 &c. may be modified by the signals from a device A in dependence on the ambience of the studio &c. The white noise source 5 and filters f1-f2, f2-f3 &c. may be replaced by a number of fixed frequency oscillators. Twenty channels over a bandwidth of two kilocycles are recommended.
