Title: Evaluation of photometric measurement values
IPC: G01N30/84
Filed: 1978-09-20
Abstract: There is provided a process for rapid direct evaluation of photometric measurement values, wherein   a) all measurement positions 12 are successively scanned so that, after the last measurement position, the first measurement position is again reached, and this scanning of the measurement positions is repeated at high speed, b) the voltage thereby produced in the photometric measurement cell 6 serves for the deflection of an oscillograph 7 and c) the scanning frequency of the measurement positions is co-ordinated with the oscillograph sweep. A device for rapid photometric direct evaluation of thin layer chromatograms 5, 12 comprises   a) a rotatable receiver 10, 11 by means of which the chromatogram can be scanned with constant rotation speed by the measurement head 6 so that, after a constant time, the starting position is again reached; and b) an oscillograph 7 so connected that the voltage produced in the measurement cell 6 serves for the deflection of the oscillograph, the rotation speed of the chromatogram 5 being arranged to be co-ordinated with the oscillograph sweep.     <IMAGE>

Title: Electronic dictionary with plug-in module intelligence
Inventor: LEVY M
IPC: G06F3/16
Filed: 1978-10-18
Abstract: A portable electronic dictionary in a hand-held housing has a plurality of alpha-numeric displays and a keyboard. A plug-in module 300 contains a microcomputer 238 and a ROM 320 which stores a plurality of pairs of sequences of alpha-numeric characters and is searched by a central processing unit in the microcomputer under instructions stored as firmware in another ROM 232 forming part of the microcomputer. One sequence of each stored pair is compared with a sequence which is entered into the keyboard and stored in a RAM 234 also forming part of the microcomputer until a match is found. After one or more sequences have been entered into the keyboard and locations of matching pairs are stored in the microcomputer RAM, the pairs of stored sequences can be rolled across the display. Either sequence of each pair can be compared with a sequence entered into the keyboard to enable translations to be performed, e.g. between English and Spanish and vice versa. The plug-in module 300 may be replaced to deal with different languages. <IMAGE>

Title: Manufacture of barrel bolt
IPC: B23C3/00
Filed: 1978-10-28
Abstract: A barrel part is formed for a barrel bolt by a single milling operation using a plurality of differently sized milled cutters co-axially disposed on the same arbor. At least one cutter penetrates through more than half the depth of the barrel part to provide transverse slots whilst at least one further cutter penetrates only a short distance into the bore to provide a longitudinally extending opening. A rotary saw can be mounted co-axially with the milling cutters to sever the milled blank from a continuously extruded section. The number of milling operations and finishing operations necessary to complete the bolt barrel part are reduced by the single milling operation. <IMAGE>

Title: Open End Spinning of Composite Yarn
IPC: D01H1/00
Filed: 1980-02-13
Abstract: A method of producing a composite yarn in an open-end spinning apparatus comprises in parting a false twist to a first fibrous system 2 by means of a rotating fluid current within a nozzle 1, providing the surface of the fibrous system 2 with discrete, staple fibres 15, the front ends of which become clamped onto fibrous system 2 and the rear ends of which are mutually intercrossed by means of a second- rotating fluid current in a second nozzle 8, 1' thus forming a fibrous envelope around the first fibrous system.

Title: Determining the frequency of an alternating signal
IPC: G01R23/00
Filed: 1980-08-27
Abstract: A method of determining the frequency of an alternating signal in sampled form e.g. pulse code modulated or pulse amplitude modulated comprises inputing each signal sample sequentially (INA), recording the new and previous signal amplitude (RNPA), comparing the new and previous amplitudes (CNPA) to decide whether a zero crossing has occurred (FZC?), storing the signal amplitudes on either side of the first zero crossing (SNPF), inputting new signal samples (INSA), recording new and previous signal amplitudes (RNPS), incrementing a sample counter (ISC), comparing new and previous sample amplitudes (CNPS) to decide whether a zero crossing has occurred (ZC?), incrementing the zero crossing counter (IZC), deciding whether the nth zero crossing has occurred (NZC?), storing the sample amplitudes on each side of the nth zero crossing (SNPN), signalling to the calculator unit that the nth zero crossing has occurred (SNZC), reading the sample stores (RSS), reading the sample counter (RSC), and calculating the frequency (FC). The frequency may be calculated from the relationship   <IMAGE>  where N is the number of cycles of the alternating signal in the period between the first and nth zero crossing,  Ts is the period of the signal samples, Ns is the number of sample intervals between the first and nth zero crossing,   a1 is the signal amplitude immediately before the first zero crossing, a2 is the signal amplitude immediately after the first zero crossing,   a3 is the signal amplitude immediately before the nth zero crossing, and a4 is the signal amplitude immediately after the nth zero crossing.     Apparatus for performing the method is disclosed and its use in MF signalling receivers for telephony explained. <IMAGE>

Title: Hydraulic shock-absorbing arrangement suitable for supporting pipes
IPC: F16L3/217
Filed: 1981-02-10
Abstract: A shock-absorbing support arrangement comprises a cylinder 1, filled with hydraulic fluid, having a hollow piston 2 with a plurality of ports 15, 16 in each end face 12, 14. Valve plates 17, 18 are each biassed away from the ports in each end face, and are dimensioned so as to be capable of closing all of the ports in one face or the other simultaneously. Slow piston movement does not affect the valve plates. Sudden shock on the piston rod moves one or other plate to close all its ports simultaneously. Fluid flow normally takes place past both outer and inner periphery of each plate thus allowing closer spacing and therefore quicker response than prior art proposals. Accessible screws 20 permit easy adjustment. The parts are disposed in a circle. <IMAGE>

Abstract: A screw-threaded container and closure cap have complementary stop means which prevent over-screwing of the cap onto the container. In a particular embodiment a screw- threaded container 5 has attached to it a closure cap with a screw-threaded skirt 2, and unscrewing of the cap from the container must be preceded by deforming a flexible annular band 8 attached to the cap skirt by bridges 7 so as to place flexible fins 9 formed on the band 8 clear of otherwise abutting lugs 10 formed on the container neck. Over-screwing of the cap on the container is prevented by stop means formed on the cap and the container, for example a truncated thread start 15 on the cap and a buttress 14 depending downwardly from the thread 13 on the container neck. <IMAGE>
