Title: Electric resistance furnace for the thermal treatment of metals and other substances
IPC: H05B3/02
Filed: 1928-09-17
Abstract: 297,826. Infra Soc. Anon., (Assignees of Sorrel V., and Lafont, A.). Sept. 29, 1927, [Convention date]. Resistance furnaces. - A furnace for the heat treatment of metals and other substances comprises a metallic chamber b heated by resistances c regulated by means comprising a balance l from one arm of which a magnetic body m<1> is suspended in the heating chamber in a magnetic field which may be created by means of a magnet d. When the body m<1> attains a temperature at which its magnetic properties disappear the arm of the balance rises and the switch n is opened to vary the heating effect either directly or through a relay. The variation may be produced by altering series connections to parallel, by altering star connections to delta, by interposition of a resistance, by altering transformer connections, or by means of an induction regulator. By choosing a suitable material for the body m<1> the temperature of the furnace can be kept constant or can increase very slowly after the critical point is reached. The body m<1> may be constituted by the material to be treated. A thermo-couple connected to a galvo may be fitted to ensure that the heating is stopped at the required temperature. The chamber b may be of copper, aluminium, bronze, german silver, ferro-nickel, nickel, nickel-chromium, silver, gold, platinum, or tungsten. 'The lid g is in two jointed sections.

Title: Improvements in or relating to telephone answering and recording devices
Inventor: WARREN WILLIAM EDWARD
IPC: H04M1/654
Filed: 1960-08-04
Abstract: 912,283. Substation apparatus. SOUTHERN INSTRUMENTS Ltd. Aug. 1, 1961 [Aug. 4, 1960], No. 27102/60. Drawings to Specification. Class 40 (4). In a device for answering and recording incoming telephone calls such as described in Specification 853,024, the operation of the answering device is delayed until pay tone ceases or for a predetermined period whichever is the shorter. In the described embodiment 15 seconds after the first ringing pulse is received a thermal delay switch operates and, if the subscriber has not answered, the next ring- ing pulse starts two valve timing circuits. One timing circuit has a delay of 2¥ seconds and, if the pay tone is not present on the line at the end of this time the delay circuit connects the answering device to the line and initiates the conventional opening announcement. If the pay tone is present on the line the delay circuit is reset by each pay tone pulse to give a further ¢-second delay. The answering device is therefore connected to the line half a second after pay tone pulses cease. Should the pay tone pulses not cease within 12 seconds the second delay circuit operates to connect the answering device to the line as before.

Title: Improvements in or relating to systems for signal transmission by pulse code modulation
IPC: H03M1/00
Filed: 1962-07-17
Abstract: 982,204. Delta modulation. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 17, 1962 [July 20, 1961], No. 27430/62. Heading H4L. In a delta pulse code modulation transmission system, quantization noise, particularly at low input signal levels, is substantially reduced by feeding to the normal differencing circuit, controlling the pulse modulator, a unidirectional voltage proportional to the input intelligence signal level and compensating therefor by modulating the comparison signal, derived by integration in the normal feedback loop, in accordance with the averated amplitude of the transmitted pulses. Transmitter.-As shown (Fig. 1a) speech signals from a source 1 pass via a filter 2 and amplifier 3 to the differencing circuit 4. A unidirectional " level " voltage proportional to the speech signal level, derived via a detector 19 and filter 20, is also fed to the circuit 4 which, in known manner, controls the pulse modulator 8 to produce an output pulse or no pulse according to whether the comparison signal fed over line 5 from the integrator 11 is less than or greater than the speech signal as modified by the " level " signal. The code modulator output pulses after regeneration at 9 are fed to line 10 for transmission and are also fed to a modulator 21 in the feedback loop 6 where they are amplitude (or duration) modulated according to the averaged amplitude of the output pulses in line 10, by a direct voltage, derived by smoothing the output pulses at 22 and fed to the modulator 21 over an adder 24 in which a constant reference direct voltage at 23 may be added. A constant reference direct voltage from a source 25 may be added to the " level " voltage in the differencing circuit 4 so that in the absence of a speech signal, pulse signals are transmitted at a density of 30% of the density at the maximum pulse repetition frequency. The reference voltage 23 is such that in the absence of a speech signal the modulator 21 reduces the amplitude of the code pulses to 5% and causes the modulator 21 output pulses to vary in amplitude substantially proportionally to the " level " voltage. A pre-emphasis (differentiating) network 30 is preferably used in the input to the " level " voltage circuit 19, 20, the output of which may be fed, alternatively, to the output of the modulator 21 (as shown dotted in Fig. 1a). Receiver (Fig. 1b) The received pulses are regenerated at 13 and amplitude modulated at 26 by a voltage corresponding to the density of the transmitted pulses and derived by a smoother 27 to which is added at 28 a reference voltage 29 which is such that in the absence of a speech signal being transmitted, the output of modulator 26 is suppressed. The modulator output pulses are integrated at 15 and smoothed at 16 to reconstitute the speech signal which is fed via an amplifier 17 to a reproducer 18. Modifications.-The invention may also be used with a delta modulation system in which the output pulses differ in polarity. Specification 684,318 is referred to.

In a spring-applied braking system including a fluid control circuit incorporating a selflapping valve, the self-lapping valve is operable by a cam arrangement which comprises locking means to lock the valve in the " brake applied " position and release means by which the cam arrangement can be released from locking the valve. The self-lapping valve comprises a cap 3 rotatable about axis 4 by means of handle 6 on the innermost end of which there is a pin 7 engaging a bore 8 in extension 9 of a first face cam 10, cam 10 being free to rotate with handle 10. A second face cam 11 in contact with cam 10 is held in the valve body 2 so that it cannot rotate about axis 4, the cams being resiliently biased together by a spring 13. A pin 14 is provided concentric with axis 4 and located slidably in the first cam 10, its end abutting an extension 15 of cam 15: movement of pin downwards parting the two cam profiles 16, 17 via spring 13 and piston 20 against the force of spring 23. The movement of pin 14 is limited by a further pin 14a. On the cam profile 16 there is a projection 18, Fig. 2, which engages with a recess 19 on the cam profile 17 of earn 11 when the brakes are in the fully applied position: when it is desired to release the brakes pin 14 must first be depressed to release the handle, by separating the cam faces sufficiently for cam surfaces 31 to engage when the handle is rotated.
