Title: Optical Apparatus for Determining Transmitting and Reflection Densities of Sheet Material
Inventor: EIGL JAN
IPC: G02B21/00
Filed: 1967-11-20
Abstract: 1,190,070. Densitometers. CESKOSLOVENSKA AKADEMIE VED. Nov. 20, 1967 [Nov. 18, 1966], No. 52646/67. Heading G1A. A densitometer is adapted to measure both the reflectance and/or scattering characteristic and the transmitting characteristic of the same point of a stationary sheet of material. As shown light from a source 1, the output of which is maintained constant by varying the power supply to compensate for colour change in the filament is collimated by lenses 3 for passage through a colour filter 4. The resulting mono-chromatic light is split at 22 by a transparent mirror into a measuring beam 0 1  and a compensating beam 0 2  which operate alternately under the control of a maltese disc which alternately interrupts the beams at A and B. The measuring beam passes through an internally reflecting prism 6 and a manually adjustable optical wedge 21 to a mirror 7 which can be set to either of two positions. With the mirror in the position shown the light passes along a path 0 4  via lenses 8, 9 and a prism 10 and impinges on the point P of the sheet material 30 under test. Light transmitted by the sheet material at that point passes through a transmitting assembly as indicated at 11d and is split by a prism assembly 14a into a beam on to a photometer 13 and a beam 0 14  again split by a prism 14b leading to the eyepieces 14e and 14f of a microscope. If the mirror 7 is in the dotted line position the light is reflected by a prism 15 and passes through lenses 16 and 17 to be reflected by a prism 18 on to the upper surface of the material at the point P, for reflectance and/ or scattering characteristic determination. Various alternative transmitting assemblies are mounted on a rotatable member (not shown) so that they can be brought to the position lid. One assembly allows an image of the sheet 30 to be seen through the microscope while other assemblies detailed function to receive transmitted, scattered and reflected light respectively. The compensating beam 0 2  is transmitted along a paths 0 7 , 0 8 , 0 9 , 0 10 , and 0 11  is sequence and arrives at the prism assembly 14a where it is combined with the light from the transmitting assembly. The photometer receives these two beam alternately and a light transmitting wedge 32 is automatically adjusted until the beams are attenuated to the same extent. A paper record may be derived from the position of the wedge. The apparatus may be used to examine densities and lusters in polarized light, a rotatary polarizer such as a flat polarizing filter or a rotating Nicol prism being included in the illuminating light beam and a rotating analyzer being included in front of the transmitting assembly.

Title: Improvements in or relating to pulse-gating circuit arrangements
IPC: H03K23/00
Filed: 1968-11-07
Abstract: 1,246,836. Pulse gating. SIEMENS A.G. 7 Nov., 1968 [8 Nov., 1967], No. 52738/68. Heading H3T. In a pulse gating circuit timing pulses at E are transmitted to the output(s) A1 (A2 . . .Am) through a capacitor C1 and gating diode(s) D31 (D32 ... D3m), conduction of a timing pulse through the diode(s) being controlled by a transistor T in response to a control input(s) S1 (S2 ... Sn) blocking of D31 when T goes off being delayed by a time determined by the capacitor C1 and the resistance of a discharge path independent of T. The transistor T is normally ON, with negative potentials at all the S1 . . . Sn inputs, so that the collector and hence the junction C of the capacitor C1 and diodes D31 . . . D3m are at zero potential. Consequently, negative going timing pulses at E have their leading edges differentiated by the capacitor C1 and the low resistance of the conducting transistor to give negligibly small pulses at C, and their trailing edges differentiated by the capacitor and resistor R4 (a diode D2 being reverse biased now, to isolate the transistor) to give positive going pulses which pass through the diodes D31 . . . D3m. When the transistor is turned off by a zero level potential at any one input S1 . . . Sn, the point C goes negative to -U b ; consequently even the positive-going pulse resulting from differentiation of the trailing timing pulse edge only reaches zero potential, and the diodes D31 ... D3m do not conduct. The capacitor C1 governs the rate of change of potential at the point C when a control signal changes the conductivity state of the transistor T. In a modication (Fig. 2, not shown) the output of the gating diode (D3) is connected to an intermediate positive potential (potentiometer R5, R6) instead of to zero potential, and to a capacitor (C2) which is in turn connected to an intermediate negative potential (potentiometer R7, R8) and to the output diodes (D41 . . . D4m). This arrangement provides a dead band so that  the output does not transmit spurious small magnitude pulses of either polarity. The gates control shift registers.

Filed: 1969-10-28
Abstract: 1287779 Nuts YORKSHIRE IMPERIAL METALS Ltd 13 Oct 1970 [28 Oct 1969] 52769/69 Heading F2H A nut has at least one spanner engaging portion 4 undercut to form a canti-lever 8, the length and thickness of which is such that when a predetermined torque is exceeded the cantilever 8 is deflected sufficiently for the gripping surfaces of the spanner to lose their grip on the nut. The nut may be cylindrical with projections, e.g. semi-cylindrical for engaging the gripping surfaces of the spanner and alternate portions 4 may be provided with canti-levers 8. In the embodiment of Fig. 3 (not shown) the portions 4 may be relieved and may be non-planar, e.g. curved. A nut in which the ends 9 of the canti-levers 8 lead during rotation to tighten the nut prevents over tightening and a nut in which the ends 9 trail during tightening cannot readily, if at all, be unscrewed with an open ended spanner, which provides a degree of security or safety. The nut may be injection moulded from acetal polymer and is particularly useful for plumbing fittings with packing or sealing material of which the effectiveness would be destroyed by overtightening.

Abstract: 1,170,775. Monostable circuit. TATEISI ELECTRONICS & CO. 25 Nov., 1966 [27 Nov., 1965], No. 52859/66. Heading H3T. [Also in Division G1] A transistor monostable T8, T9 driving a solenoid RY through a transistor T10 is triggered to its unstable state by positive pulses at T8 base derived from positive or negative pulses occurring at the collector of a preceding transistor T6. The pulses from T6 are applied both directly to a differentiator C11, R19 and, after inversion in a transistor T7, to a differentiator C12, R21. The diodes D2, D3 thus pass positive trigger pulses to T8 base in response respectively to positive and negative pulses at T6 collector.

Abstract: 1525100 Demand assignment communication INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1975 [30 Dec 1974 (5) 26 June 1975] 52958/75 Heading H4M A plurality of networks, with corresponding control units 10 are coupled via network access control unit, concentrator, and mulitplexer 12, Fig. 4, which provides for assembly of a burst, demand assignable signal for communication (e.g. after modulation via a satellite). The communicated assembled signal is transmitted to all networks for demultiplexing, deconcentration and distribution, the burst duration being variable in dependence on network loading. In the presence of blocked demand, such demand is dispersed over all networks. In meeting demand data has priority over telephonic communication, continuing such communication having priority over transitional telephonic communication. The telephone channels utilize time assignment speech interpolation (TASI). Network control units, Fig. 3 (not shown).-The network control units, receiving baseband, or modulated, digital data, or, via PBX equipment (1.1) signals derived from telephones 1.1.1, function to pass the information in digital form via buffers to slot interchange memory (26), the information being communicated to other ports, or, in TASI format, to other networks or to the unit 12. The network control units, and the unit 12, see Fig. 4 (not shown) make use of microprocessors in their control. The various information and control formats used are disclosed in relation to Figs. 5-10 (not shown), as are the means for establishing and terminating signal paths, Figs. 12, 13A, 13B (not shown).
