Title: Balanced low-frequency amplifiers
IPC: H03F3/36
Filed: 1951-10-18
Abstract: 697,064. Valve amplifying circuits. NEDERLANDSE CENTRALE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK. Oct. 18, 1951 [Oct. 18,1950], No. 24365/51. Class 40 (vi). A push-pull amplifier the output of which is independent of H.T. supply voltage fluctuations comprises two valves directly connected over a pair of resistances 3, 4 the junction point 8 of which is maintained at the same D.C. potential as the valve anodes. The output is taken from adjustable tapping points A, B on the resistances 3, 4. A static. balance having been obtained by adjustment of the valve characteristics so that both anodes and the point 8 are at the same potential, no D.C. passes through the resistances 3, 4 and so the circuit may be balanced dynamically, by adjustment of the tapping points A or B, without disturbing the static balance. The potential required for the point 8 may be obtained from a potentiometer across the H.T. supply, Fig. 3 (not shown). It is shown in the Specification that this may lead to an adjustment of the tap A or B giving low gain; this may be overcome by making the dynamic impedance of the valves much greater or much smaller than the resistance of the anode loads 1, 2. Alternatively, one or other of the resistances comprising the potentiometer may be non-linear, i.e. have a dynamic impedance much greater or smaller than its D.C. resistance. The anode resistances 1, 2 may in addition be returned to a tapping-point on a potentiometer of this type.

Filed: 1964-06-12
Abstract: 1,015,106. Injection and extrusion moulding machines. GEB. BUHLER. June 12, 1964 [June 14, 1963; May 20, 1964], No. 24470/64. Heading B5A. An injection moulding machine having a nozzle assembly 12 slidable in a nozzle housing 2 between open and closed positions, can be used for extrusion by retaining the nozzle assembly in the open position by means of a latch 3 as shown in Figs. 1, 2. In one example the latch 3 has an aperture having three portions 41, 42, 43 of different widths. In the position shown in Figs. 1 and 2 the narrowest portion 41 co-operates with recessed parts 31 in the body 4 of the nozzle. Passages 7 through the nozzle body are thus open for the passage of material from the plasticizing cylinder. By shifting the latch 3 to the right in Fig. 2 the nozzle body can be given limited axial movement determined by the engagement of an aperture portion 42 with the face 62 of an annular groove 32 in the nozzle body 4. Pressure of material in the plasticizing cylinder closes the passages 7 until the body is again moved to the right by contacting a mould 9. The widest portion 43 of the latch 3 enables the nozzle assembly 12 to be removed from the housing 2 for cleaning &c. Figs. 3, 4 (not shown) illustrate a modification comprising a generally U-shaped latch 23 which is removable from the nozzle housing. In a further modification (not shown) the latch may be axially movable and/or rotatable relative to the housing.

Filed: 1952-10-01
Abstract: 719,514. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd. (Mergenthaler Linotype Co.). Oct. 1, 1952, No. 24582/52. Class 100 (3). Assembling matrices.-A typographical composing machine of the kind known under the Registered Trade Mark " Linotype " comprises an assembler slide brake to normally prevent retrograde movement of the slide, a poweroperated cam-shaft for raising the elevator, and means controlled from said power-operated cam-shaft for releasing the assembler slide brake prior to the raising of the elevator so as to cause the slide through the line resistant to press the composed line yieldingly against the rotating starwheel. The machine is of the general construction described in Specification 706,438, and the assembler slide brake 15, Figs. 1 and 7, is momentarily released before the elevator B rises by means of a rotary solenoid 34, Figs. 1 and 3, energized by the closing of a switch 42 by a cam 40 on the cam-shaft 28 for raising the first elevator. Alternatively, the brake may be released by a mechanical connection from the cam 40. As the elevator is raised and nears the transfer position, a projection 45 releases the brake again through a mechanical linkage 46, 46a, 47, 48. The link 47 is mounted on the plate P of the hinged assembly frame, which is sometimes swung open, this being permitted by the split linkage arrangement 46a, 47, projections 46a being tapered and conical to facilitate re-engagement. The brake is restored on descent of the elevator by a projection 50. The elevator is provided with main and auxiliary rails for supporting at either of two levels matrices formed with upper and lower characters. The lower ends of assembled matrices should be seated on the rails to the left of small detaining plates 32, Fig. 1, and the upper ends are held against displacement to the right by spring-urged locking pawls 20. When the brake is released the first time, a spring 14 forces the slide to the right and forces the last matrix against the plates 32, so that the star-wheel can push the upper end of the matrix past the pawls if it was not previously properly aligned.

Abstract: 1482976 Metal detector P A SPENCER and G L FRY [trading as ARADO ELECTRONICS]  12 Jan 1976 [9 June 1975] 24668/75 Heading GIN A metal detector comprises an audio frequency oscillator 10 having a tuned circuit determining the oscillation frequency, say 4.5 kHz., and including a search coil 11 of which the inductance is varied by proximate conductive or ferromagnetic objects. The oscillator output is multiplied to a frequency of about 9 MHz by means of filters 12, 14 and amplifying and squaring circuit 13. The output from filter 14 is mixed, with the output of 9 MHz reference oscillator 15, in mixer 16 to provide sum and difference frequencies including a frequency in a band centred on 200 Hz. One or other of oscillators 10, 15 is turnable so the difference frequency may be adjusted to a desired value. The difference frequency is selected by a tuned audio amplifier 17 and applied to headphones 18 or a frequency meter. The pitch of the audiotone produced rises for non-ferrous objects and falls for ferrous objects. The detector has the coil in a paddle on the lower end of a rod with a handle at the top allowing the user to move the coil over the ground surface. At 4.5 kHz the coil may have 110 turns and a diameter of 18 cms. For detecting small coins and jewellery of poor conductivity compared with silver the oscillator 10 frequency is 9 kHz and the coil has 60 turns.

Filed: 1972-05-25
Abstract: 1375268 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 25 May 1972 [1 June 1971] 24695/72 Heading H4K  An interface between a stored programme processor and a cross-bar switching network includes a first register for receiving a word signifying which group of a plurality of groups of like components is to be addressed, a second register for receiving a control word whose individual bits specify the state to which at least some of the stores of the particular group are to be set, a third register for receiving an inhibit word whose individual bits specify which stores of the particular group are not to have their states changed, and a masking circuit for combining the two words so as to produce a control function that is used to set the stores of the designated group. Network equipments such as inter or intra exchange junctors contain a plurality of components, e.g. signalling and battery feeding relays, the latter each being represented by a store in a set of stores allocated to a junctor. In the interface the groups of stores, e.g. bi-stables, representing similar components are arranged in matrices of which each column corresponds to a particular equipment and each row represents corresponding components, e.g. relays, of each of the equipments. In operation, the processor transmits an address identifying a particular row of a particular matrix whereby a pair of decoders are enabled to mark this row for implementation by the control function. The latter is determined by a masking circuit consisting of NAND gates whose net effect is that they produce no significant output (actually two zeros, Fig. 4, not shown) if a bistable is not to be set or reset, i.e. the corresponding relay is not to have its state altered, and produce either a 0 or a 1 output if a bi-stable is to be reset onset respectively. In this manner some of the members of a group of components may be controlled without the processor needing to define the state of all the members of the group.
