[Also in Division G1] Optical apparatus for measuring the light absorption or reflection properties of a sample comprises a bundle of fibres 10 to one end 11 of which a probe 12 is attached for immersion in or presentation to the sample while the other end is divided into two branches; light passing along one branch of the bundle 10 is reflected back through the second branch to comparator means where it is compared with a reference beam received directly from the same source of light by means of a further branch 18 of the fibre bundle 10. The two beams thus produced pass through lenses 21a, 21b and are then interrupted alternately by a chopper 23. The beams are alternately received by a photo-multiplier 24 from which the output passes to an amplifier 27. The output from the amplifier 27 is taken to a phase sensitive detector 29 and a servomotor 30 which moves a wedge 22 across the reference beam to equalize the beam intensities received by the photo-multiplier 24. A pen 31 gives a graphical representation of movement of the wedge.

Abstract: 1,250,377. Semi-conductor devices. SONY CORP. 22 Aug., 1969 [24 Aug., 1968 (2)], No. 41944/69. Heading H1K. A polycrystalline region 103<SP>1</SP> is provided in an integrated circuit semi-conductor wafer 108 in the vicinity of one of the circuit elements, e.g. a transistor Tr, so that when a material producing carrier recombination centres is diffused into the body, e.g. from a vapour deposited layer 110 overlying an oxide layer 105 having an aperture 107 adjacent the polycrystalline region 103<SP>1</SP>, the preferentially very high diffusion rate in polycrystalline material as compared with that in monocrystalline material causes the entire region 103<SP>1</SP> to act as an effective diffusion source, resulting in the production of a region 109 exhibiting low carrier lifetime localized in the vicinity of the transistor Tr. In the embodiment shown the polycrystalline region 103<SP>1</SP> is formed as part of a generally monocrystalline layer 103 vapour deposited on a substrate 101, due to the previous preparation of part 102 of the surface of the substrate 101, e.g. by scratching or deposition of a material having a lattice constant which differs from that of the substrate 101. A polycrystalline layer of Si may also serve as the site for the subsequently deposited polycrystalline region 103<SP>1</SP>. The circuit shown includes, in addition to the transistor Tr, a resistor region 106r. In a further embodiment comprising a transistor and a diode the vicinity of the former device is provided with a concention of carrier recombination centres in a similar manner to that described above by diffusion through an annular polycrystalline region (208), Fig. 2J (not shown), and a further annular polycrystalline region (207) surrounds the transistor and defines the lateral limit of diffusion of the carrier recombination impurity. In a modification of this embodiment the collector electrode may be situated on the first-mentioned annular polycrystalline region (208), which tends to be of low resistivity. Carrier recombination impurities referred to are Au and Cu, for use with Si or Ge wafers. The device containing the localized carrier recombination centre concentration may also be a diode.

In a welding and/or cutting torch, a handle 10 contains ducts for cutting gas and oxygen, a valve 26 being disposed in each duct and connected to a valve push rod 27 axially slidable in a bore 19 within said handle, each push rod 27 having an external screw-thread 33 for receiving thereon an internally screw-threaded actuating ring 34 which is disposed in said handle and serves upon rotation to move the push rod 27 to open or close the associated valve 26. The valve 26 co-operates with a valve seat 25 to open or close the end of a bore 24 in a connecting piece 16 through which the oxygen is supplied. The valve push rod 27 has an axial bore 40 aligned at one end with a passage 18 in the handle 10 and terminating at the other end in oblique transverse bores 41 leading to a space 43 around a cage 47 formed in the end of the pushrod 27 with which a part-spherical face 28 of the valve plug 26 co-operates. Abrasion resistant plastics slip rings 37 are located in annular slots 36 in the actuating ring 34 and sealing rings 39a and 39b in recesses 38a and 38b. A spring 30 biases apart the connecting piece 16 and the valve push rod 27 to compensate for thread clearance of the actuating ring 34. To avoid rotation of the push rod 27, pins 44 are provided which slide in bores 45 in the handle 10. The arrangement for control of the cutting gas is similar to that for control of the oxygen.

[Also in Division H2] A piezo-electric ignition device 31 according to claim 1 of the parent Specification is disposed parallel to a rotary gas control comprising coaxial pilot and main valves 2, 3 operable by cams actuated by a rotatable knob 12 carrying gearing 29 meshing with gearing 32 on the rotatable manipulator 50 of the ignition device such that an ignition pulse is produced after opening the pilot valve. To operate the device, knob 12 is first depressed against a spring 14 to engage the gearing 29, 32 after which it is rotated in one direction carrying with it a plate 9 rotatably mounted in the housing 8 of the control. At the same time a cam 10 on the plate 9 rotates a cam support 7 against a return spring 18 causing a plunger 4 to open the pilot valve 2. The igniter produces a pulse to ignite a pilot jet and the knob is held until a thermocouple, heated by the pilot jet, produces sufficient current in an electromagnet 26, Fig. 3, to retain a latch 21 in interlocking engagement with a hook 16 on the cam support 7. Knob 12 is then allowed to retract and disengage the gearing and is rotated in the opposite direction to an intermediate position causing the cam 10 to depress the cam support 7 and open the main valve 3. The knob may be operated to close and open the main valve as often as desired without extinguishing the pilot jet but should it be returned to the initial position, cam 10 depresses support 7 still further and the hook 16 slides off a pin 23 on the latch 21 allowing spring 18 to return the support 7 to its initial position and both valves 2, 3 to close. If the knob 12 is turned towards the "on" position again before the electromagnet has released, the outer edge of hook 16 strikes the pin 23 and prevents the support 7 from rotating to the ignition position and the generation of an ignition pulse.
