Title: Improvements in or relating to wall structures
IPC: E04B2/04
Filed: 1934-06-23
Abstract: 440,209. Walls ; building blocks. HOLLAND & HANNEN & CUBITTS, Ltd., 1, Queen Anne's Gate, Westminster.- (Schr÷der, W. ; 1, Rhodiusstrasse, M³lheim, Cologne, Germany) June 23, 1934, No. 18634. [Classes 20 (iv) and 87 (i)] To permit variations in wall thickness in multiples of a quarter of the minimum thickness, the bricks are made angular in plan and with the sides of definite lengths made up of a certain minimum unit a, say 2 ins., and joint thickness b. Thus in the basic form of block A, Fig. 1, the inner side 4-5 is of length a+ b, the side 5-6 is 2a+b, sides 6-1 and 3-4 are 2a, 1-2 is 4a+b, and 2-3 is 3a+b. The height may be 2a, 3a + b, 4a + b, and so on. Fig. 7 shows a wall of minimum thickness 4a+b; other solid and cavity walls are described and vary in thickness up to 6a+2b. The angle blocks, Fig. 1, may be used with rectangular blocks such as E, F, Fig. 7, C, Fig. 9, and B, C, E, Fig. 24; the lengths of such blocks may be a, 2a, 3a + b, 4a + b, and 6a+ 2b. The combinations of angular and rectangular blocks may be formed as integral Z-shaped blocks, Figs. 12, 17, 24, and 26, the dimensions of which bear definite relations to those of the unit blocks. The dotted lines 40 indicate the equivalent of joints, and apertures 15 may be round or of other shape. The blocks may be made of burnt clay, lime sandstone, or light porous concrete.

Abstract: 893,015. Anodes for preventing corrosion. READER & SONS Ltd., E. June 1, 1960 [June 2, 1959], No. 18786/59. Class 123(1). An impressed-current cathodic protection electrode comprising an electrode proper 4 has firmly attached to its lower end a porous ceramic part 3 which is less conductive to electrical currents than the electrode proper and is adapted to retain, at least temporarily, a film on diffusion of liquid after immersion in and withdrawal from such liquid so that, when the electrode is positioned with the part 3 immersed in an electrically conductive liquid and the level of the liquid is lowered, the electrical resistance to the current flow between the electrode proper and the liquid progressively increases as the liquid level is lowered and the liquidretained by the part 3 leaks away. In this manner the potential across the gap between the collar 3 and the liquid surface is insufficient to cause a spark when the liquid eventually drops below the level of the part 3. In a modification, Fig. 2, the electrode proper comprises a film of platinum 8 over the part of a titanium rod 6 which extends above a lower collar 7 which is adapted to retain a thin layer of liquid upon its upper surface when the liquid falls below the platinum part 8.

Title: Silicon carbide resistance bodies and methods of making same
IPC: C04B35/573
Filed: 1957-06-14
Abstract: A temperature-sensitive resistor comprises a mass of recrystallized silicon carbide, the crystal lattice of which contains a small amount (up to 0.34 per cent by weight) of boron; it is stated that this enhances the sensitivity of the resistor to changes of temperature. Anhydrous boric oxide is mixed with silica sand, coke and sawdust in the proportions described in the Specification and furnaced in known manner.  The resultant crystalline silicon carbide which contains 0.20 per cent by weight of boron is crushed and graded, and then moulded and fired to form a resistor of desired shape. Alternatively, boric acid may be added to granular silicon carbide and mixed with sodium silicate and water, or other temporary binder, rammed to shape, and fired in a reducing atmosphere to 2000-2500 DEG C.  The material can be moulded to any desired form and size by conventional methods, glycerine or other plastifier being added if necessary, and can be provided with electrodes and connecting wires in known manner.  It is stated that the boron assists the process of recrystallization, which follows a growth pattern of pure pyramiding hexagonal layers.  Specification 17911/92, [Class 39], is referred to.

Abstract: 1,108,154. Electronic counters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 18 June, 1965 [6 May, 1964], No. 18849/64. Heading G4A. [Also in Division G3] According to the number stored in a first counter B5-B8, so a proportion of the pulses applied to a second counter B1-B4 are passed to an output terminal. Both counters are of binary-coded decimal type with different feedback arrangements, whereby the first is weighted 1224 and the second 1125. Carry between binary stages is effected over Q terminals and pulse outputs to AND gates A1-A4 is effected over P terminals, the counters being arranged for this purpose in opposite sense. The circuit shown represents the first decimal place but provision may be made by carry from B4 and B8 for subsequent decimal places. The first or controlling counter may be reversible (Fig. 13, not shown) as described in Specification 1,108,153. The apparatus may be used in a retro-active system, Fig. 14, to maintain the speed of a motor M at a specified rate. Feed-back loop 3 provides a first degree of control. A finer control is provided by pulse generator 4, the output of which over a 1- second period is stored in control counter 5211. This then controls the output of an oscillator and main counter 1224 to feed pulses to circuit 5 which also receives pulses from generator 4. In the manner described in Specification 1,098,457, the circuit 5 deletes coincident or corresponding pulses so as to drive counter 9 forwards or backwards. A digital-to-analogue converter 10 and amplifier 2 then complete the loop to speed or slow the motor as necessary.

Title: Process for preparing formaldehyde in stable form
IPC: C08G12/12
Filed: 1956-06-19
Abstract: Formaldehyde in stable form is prepared by contacting formaldehyde, in substantially gaseous and monomeric form at a temperature in the range 80-400 DEG  C. with an acceptor comprising urea, melamine, thiourea, phenol or a mono- or dialkyl substituted phenol, said acceptor being a liquid or being in suspension or solution, there being present at least a catalytic amount of water which is introduced to the reaction either before or during said contact with the formaldehyde, the formaldehyde and acceptor dispersion being maintained at a pH within the range of about 7 to 9 and the temperature of the dispersion being maintained at a temperature between 50 DEG  C. and the boiling point of the dispersion.  The formaldehyde may be introduced in the form of furnace gas, direct from a methanol dehydrogenation or oxidation unit.  Alternatively the formaldehyde may be used in the form of the gas mixture obtained when methane, natural gas or butane is converted to formaldehyde.  The pH is established at a value of from 7 to 9 by the addition of an alkali which is non-reactive with formaldehyde, e.g. sodium or potassium hydroxide, triethanolamine, borax or sodium carbonate.  The products may be mixed with an aqueous solution of formaldehyde at a temperature above that at which paraformaldehyde separates from the solution and this results in stabilization of the formaldehyde in the whole composition.  The formaldehyde compositions produced may be used for the production of resins (see Group IV (a)).ALSO:A stable composition of formaldehyde, obtained by contacting formaldehyde in substantially gaseous and monomeric form at a temperature in the range 80-380 DEG  C. with an aqueous solution of urea, the pH of the dispersion being maintained at 7-9 and the temperature of the dispersion being maintained between 50 DEG  C. and its boiling-point, is acidified to a pH of 6.0-6.7; the acidified product is continuously-charged to a well-stirred reactor vessel to such volume that it is filled in about 1 hour; the product is continuously withdrawn and neutralized giving a resin which is useful as an adhesive for wood.  An example is also given in which a concentrated formaldehyde solution, obtained by replacing urea with melamine, is reacted with further melamine to produce a melamine-formaldehyde resin.

Title: Parametric amplifiers
IPC: H03F11/00
Filed: 1963-05-15
Abstract: 1,047,702. Parametric amplifiers. K. SCHMID. May 15, 1963 [May 15, 1962], No. 19314/63. Heading H3B. In a parametric amplifier pump energy is stored in a parallel resonant circuit including a centre-tapped inductance forming a bridge with two non-linear capacitors and is phase moduiated by the signal to be amplified, the resultant modulated signal being fed to a phase-sensitive detector having a single-ended output. As shown in Fig. 1, pump power P 1  is supplied to a parallel resonant circuit comprising divided inductance L 1  and two variable capacitance diodes D 1 , D 2  which circuit is tuned to the pump frequency fp and is arranged as a balanced bridge. The signal to be amplified is applied to input 1 so as to cause the average junction capacitances of the pumped diodes to vary with time with the result that the pump energy is amplitude and phase modulated at the signal frequency. The phase modulated signal is then fed to a phase sensitive circuit comprising two detector diodes D 3 , D 4  connected to the parallel resonant circuit and which add the phase modulated pump energy P<SP>1</SP> 1  and the quadrature pump energy P<SP>1</SP> 2  supplied through capacitors C 1  and C 2 . The rectified currents, i.e. the sum and difference of half the pump voltage U 1  appearing across the pump circuit and the voltage at 4 and 6, flows through diodes D 3 , D 4  and resistors R 1 , R 2  to load R L . Thus a phase shift of the pump voltage U 1  alters the magnitude of the voltages applied to detector diodes D 3 , D 4  causing a change in the rectified voltages + UD 3  and - U D4  and hence a change in the output voltage. In a second embodiment, Fig. 2, resistors R 1 , R 2  are connected to ground instead of the tap on inductance L 1  and the polarity of the diode pairs D 1 , D 2  and D 3 , D 4  is chosen such that the output voltage at 7 is in phase with the input voltage 1. The total output voltage is fed back into the input circuit and is in series with the input voltage so that the circuit operates in the manner of a cathode follower. The D.C. component of the output voltage also acts to automatically control the frequency against changes due to the variations of capacitance in the parallel resonant circuit. In the arrangement of Fig. 3 (not shown) the quadrature pump signal P 2  and the pump signal P 1  applied to the bridge circuit are obtained from a signal generator and delay line. For V.H.F. operation as shown in Fig. 3 the pump generator is coupled inductively to the pump circuit but in the case of a low frequency amplifier the tapped inductance may be bifilar wound, Fig. 4 (not shown), allowing coupling of pump signal P 1  by means of a resistor to one end of the tapped inductance. For low frequencies a phase shift network is employed in place of the delay line.

Title: Record defect compensation apparatus
IPC: G11B20/06
Filed: 1975-05-08
Abstract: 1503807 Television systems RCA CORPORATION 8 May 1975 [6 June 1974] 19322/75 Heading H4F To compensate for defects in the video signal generated by the pick-up of a video record player, detection of a defect causes a portion of the present image line signal to be replaced by a substitution signal, e.g. a portion of a preceding image line signal. The effect of the defect-detection is maintained until after the defect has ceased. The video signal, e.g. from a video disc player having a capacitive pick-up is a frequency modulated signal. It is passed via limiter 23, Fig. 1, to unit 25 which generates a fixed parameter pulse at each zero-crossing. The pulses pass to a filter 27 having a pass-band equal to the bandwidth of the recorded video signal, the filter providing a demodulated signal for display. The pulses also pass to a defect detector 30 which includes a filter 31 having a passband substantially greater than that of the recorded video signal. If the amplitude of the signal W from filter 31 lies above or below the range of values occupied by the defect-free demodulated video signal comparator 33 or 35 will generate a defectindicating signal D for as long as the signal W lies out of range. In the absence of a defect, complementary signals Cl, C2 cause switching unit 70 to pass the normal demodulated signal applied at N to output O which feeds a display. However when a defect signal D occurs it charges capacitor 52 to the peak of the signal and the capacitor then discharges slowly via resistor 54. When the potential on the capacitor exceeds a threshold level set by resistors 58, 59 signals C1, C2 are reversed so causing unit 70 to pass a substitution signal applied at S to the output O. Because capacitor 52 discharges slowly Cl, C2 will not revert to their normal state until after the defect in the video signal has ceased. D.C. mismatch on switching is reduced by operation of gating transistors 90, 91 in unit 70 in inverted saturation mode.
