Abstract: 103,573. Campbell, H. E. April 7, 1916. Window frames ; window sills and lintels; sash-cord attachmerrts; sashes balanced by weights. - In window frames and sashes made of metal, the suspension devices are enclosed within the lintel A and jambs C, and the jambs C, lintel A, and sill B are bolted together by bolts D. Bent plates E, J, I form the jambs C, which are divided by a partition N, to which is secured a T-shaped bar O and springs W, S. The springs carry angle strips T, V, which normally close the spaces between the plates J, I and the bar 0, above the lower sash and below the upper sash respectively, but which are bevelled to engage the sash frames and to be pushed aside when the windows are raised or lowered. The window pane is held between plates h, i, Fig. 8, which may be enclosed within the jambs so as to make the whole width of the frame available for light space. Attached to these plates are plates R projecting to the inner surfaces of the jambs, and to these plates are connected the weighted chains 12 which pass over chain-wheels 13 mounted in ball bearings in the lintel. The ball bearings are carried by blocks c integral with the bottom plate a of the lintel. The chain-wheels carry supporting-seats for the shaft 14, which is clamped therein by covers f and stirrups e. A flange 19 is provided for raising the lower window, and the sill B comprises a flange 16, which enters between the plates 17, 18 and forms with a bar 21 a weather-proof joint.

Title: Improvements in and relating to the production of sound records
IPC: G11B7/00
Filed: 1932-02-25
Abstract: 397,205. Sound-records. THOMAS, R. V., 18, Rue Leon Delhomme, Paris. Feb. 25, 1932, No. 5673. Convention date, March 2, 1931. Drawings to Specification. [Class 40 (ii).] Sound is recorded optically by a beam of punctiform cross section oscillating at a frequency varying from 0 to 20000 per second, and the record so formed is adapted to be duplicated by a photo-engraving process. The record may be formed on a, travelling band or as a spiral trace on a disc. Recording may be effected by an oscillograph system. The record is first developed, then copied on to carbon paper, and this copy is transferred on to a plate of polished metal coated with a sensitive layer. The metal is engraved by means of powdered neutralized iron perchloride spread on the surface of the plate and, after the first etching, the protective layer may be reinforced by ink applied by a roller and a new etching effected. A counter-matrix with a record in relief may be obtained from this matrix for use in making discs or bands for reproduction by an ordinary sound-box or pick-up. Alternatively, by commencing with a positive of the record, the metal. plate may be formed directly with the record in relief. Reference has been directed by the Comptroller to Specifications 715/01, 4661/03, [both in Class 40, Electric telegraphs &c.], 1532/11, and 280,923, [both in Class 40 (ii), Phonographs &c.].

Title: Improvements in or relating to multiple frequency oscillators
IPC: H03B21/02
Filed: 1947-02-28
Abstract: 637,179. Valve generating circuits. SOC. INDEPENDANTE DE TELEGRAPRIE SANS FIL. Feb. 28, 1947, No. 5890. Convention date, Feb. 28, 1946. [Class 40 (vi)] A multiple frequency generator comprises three valves having tuned anode circuits and at least one of which is a frequency changer, each frequency changer having its grids connected respectively to the anodes of the other tubes and its anode connected to a grid of at least one other tube. Fig. 2 shows a simple form comprising frequency changers L1, L2, L3 connected so that the output of each valve serves as an input for the other two. When the circuits are tuned to frequencies F1, F2, F3 such that F3=F1+ F2, the system is self maintaining. Also the sums and differences of the frequencies F1, F2, F3 will be produced and may be brought out by resonant circuits in the respective anode circuits. These frequencies will have the requisite relationship for maintaining oscillation, and will in their turn produce further sets of sum and difference frequencies ; and so on indefinitely. This leads to the arrangement of Fig. 6 in which the members of the chains of resonators in the respective anode circuits are tuned to frequencies proportional to the numbers in the squares. Thus valve L2 produces the odd harmonics, and valve L3 the even harmonics of the frequency to which the anode circuit of L1 is tuned. If the circuits in L2 are variable over the ranges 1 to 2, 3 to 4, &c., and the circuits of L3 are variable over the ranges 2 to 3, 4 to 5, &c., then the whole range 1 to 11 can be obtained. with continuous variation. In Fig. 8, an oscillation generator L1 is connected to two frequency changers L2, L3. If the frequency F2 is stabilized by a quartz, variations in F1 are accurately transposed to F3. The anode circuits of L2, L3 may have chains of resonators operating in the manner of Fig. 6. Fig. 10 shows an arrangement for obtaining high harmonics by means of a frequency changer L1 tuned to the fundamental F0 and excited by successive harmonics generated by L2, L3. If the anode circuits in the Fig. 2 arrangement are tuned to the same frequency, three phase oscillations are produced.

Class 126 A preformed throat unit for fitting in a fireplace opening between the top of the fireback and the flue, comprises front, back and side walls enclosing a duct converging upwardly and having its outlet set behind its inlet, and the front wall is recessed to leave a gap between the front of the unit and the top of a fireplace surround. The unit, which may be a single moulding of refractory material or may be in multi-section form, has a rectangular base forming flanges 15, 16 at the sides and front. The flat back wall 11 slopes rearwardly from the base, and the side walls 12 and front 10 are set back from the flanges and flare outwardly into the base. The duct 20 is a regular trapezium in cross-section, its parallel front and back converging towards the top, and the sides converging towards the back, and also converging upwardly. The back and sides are flat but the front flares outwardly near the bottom. The top of the back and side walls are level, and the front wall extends above them to form a ledge 21, which supports the brickwork immediately over the fireplace. The swept back front wall 10 affords a space between the throat and the surround. A bracket 25 for a fire guard may be secured by a bolt passing through a hole in the flare of the front wall. In a modification, Fig. 6, the outer face of the front wall 10 is vertical, and has a recess 26 to afford a space behind the surround.

Title: Improvements relating to Pulse Generating Circuits

IPC: G04F5/10
Filed: 1967-02-08
Abstract: 1,180,402. Transistor oscillators. R. W. REICH. 8 Feb., 1967 [9 Feb., 1966], No. 5934/67. Heading H3T. [Also in Division G3] A relaxation oscillator circuit for providing timing pulses comprises silicon transistors 1, 2 coupled by a circuit including a capacitor 14, in series with a first resistor 19, the capacitor 14 being chargeable through a second resistor 13 and dischargeable through a third resistor 10, the transistors 1, 2 being connected to emitter and collector resistors 3, 6, 7, 10 to form a bridge which is unbalanced each time the capacitor 14 charges up. When the transistors 1, 2 are non- conducting the bridge is balanced and the capacitor 14 charges through resistors 10, 13, 19 and 7 until the base voltage of transistor 1 rises sufficiently to render transistor 1 conducting. The collector voltage of transistor 1 then falls to render the transistor 2 conducting to cause the capacitor 14 to discharge through resistors 15, 19, 10 and the emitter-collector path of the transistor 2. The resistor 7 may comprise the driving coil of a timepiece and form part of an electromagnetic device for advancing the teeth of a seconds or minute wheel. The frequency of the oscillator can be rendered more constant, by stabilizing the voltage across the resistor 13, during charging of the capacitor 14, by connecting a Zener diode between the negative supply terminal and each end of an auxiliary resistor in series with the resistors 10, 13. Also the resistors in the oscillator circuit may have negative temperature coefficients to reduce the variation of frequency with temperature. Instead of driving a clock mechanism the oscillator circuit may be utilized to initiate switching operations.
