Title: Improvements in and relating to speedometers
IPC: G01P3/10
Filed: 1930-11-10
Abstract: 358,763. Speedometers. STOECKLIN, C., 10, Rue Jean Varet, Paris. Nov. 10, 1930, No. 33790. Addition to 324,505, [Class 106 (iii), Fares &c.]. [Class 106 (iii).] Periodic-counter and like speed indicators.-In a speedometer of the type set out in the parent Specification, a cam operates directly a single lever which slides a double-toothed crown wheel driven from the vehicle into engagement with one or other of the two transmissions. The spindle 1 carrying a cam 2 is driven from clockwork, the cam moving a lever 3 pressed into engagement with it by a spring 22<11> so as to slide the double-toothed crown wheel 4 on the squared spindle 12 into engagement with a pinion 25 gearing with a wheel 6. The latter carries a pin 9 engaging a pin 10 on a toothed wheel 8. A pin 15 on the other side of this wheel engages an abutment 14 on the axis 7 which drives the indicating needle 19 through gears 16, 17. The wheel 8 is held by a spring catch 22. This reading will be held while the cam switches the drive to the other and similar mechanism driving the wheel 8<1>. If the speed has increased, the pin 15 of the second gear will push the abutment 14 and move the needle on. If the speed has fallen, on the stop spring 22 being released, the wheel 8 is released and under the influence of the return spring 20d returns to zero. The stop spring 22<1> is now holding the wheel 81 and the reading. The stop springs 22, 221 are operated at appropriate times by the cam 2. The pinion 51 is acted upon by a spring 11 so that engagement by the wheel 4 is cushioned. The wheels 6, 6<1> and 8, 8<1> are constantly urged towards their zero positions by return springs, such as the spring 20d.

Title: Apparatus for analysing the response of a process system
IPC: G06F17/15
Filed: 1974-10-23
Abstract: 1480727 System testing using crosscorrelation NATIONAL RESEARCH DEVELOPMENT CORP 23 Oct 1974 [23 July 1973] 34939/73 Heading G1U A system 1, Fig. 2, is tested by applying a pseudo-random chain of pulses to it and computing the cross-correlation of these pulses with the resulting output from the system. The pseudorandom chain of pulses comprises a fixed sequence of 2<SP>m</SP>-1 pulses - each pulse having one of a possible two characteristics - generated 9, 17 repetitively, ad infinitum, which pulses are effectively gated to the system 1 under test by a buffer store in such a way that during the first generation of the fixed sequence of 2<SP>m</SP>-1 pseudorandom pulses only the first pulse is applied to the system, during the second generation of the fixed sequence only the second pulse is applied to the system, and so on, this being effected by clock pulses of frequency f/2<SP>m</SP> from a divider 11, 13 whereas the pseudo-random pulses are generated at a frequency of f by a clock 10. Thus, following the application of a pulse to the system every other pulse of the fixed sequence occurs before a further pulse is applied to the system. This feature is exploited in the calculation of the required cross-correlation function, each output y r  from the system resulting from the application of the pulse x r  being digitized, 14, being reduced 16 in value by the output y r-n  (where n = 2<SP>m</SP>-1), and being multiplied 18 by every other pulse x 1 , x 2 , ..., x r-1 , x r , ..., x n  of the fixed sequence. The resulting products (y r -y r-n )x s  are distributed (over s) to respective accumulators 19, 20 so that after the initial n cycles of the pseudo-random  sequence the accumulators store a moving correlogram based exactly upon the preceding n system outputs. The final result can be displayed on a c.r.t., and to avoid cumulative errors two multi-stage accumulators 19, 20 could be utilized alternately, one being zeroized whilst the other is in use.
Patent GB-1064725-A (GB)
Title: Improvements in or relating to manufacturing metallic images by photographic means
IPC: G03C5/58
Filed: 1963-09-04
Abstract: Internal and/or external metallic images on hydrophilic non-conductive non-metallic carriers are formed when metal germ images, produced by exposure of a photo-sensitive compound which itself yields physically developable silver nitrate nuclei or which yields physically developable mercury and/or silver nuclei in a secondary reaction e.g. by treatment with acidified mercurous nitrate/silver solution, are activated and then treated with a solution of a copper, nickel or cobalt salt, or a mixture of nickel and cobalt salts, and a reducing agent to deposite metal on the developed image.  Activation of the mercury and/or silver metal germ image is effected by treatment with a solution of a salt of a platinum metal, e.g. platinum or palladium, or when nickel or cobalt is to be deposited by a short physical development with a silver salt solution containing a developer either followed by a platinum metal salt solution treatment or by conducting the nickel or cobalt deposition while the thus-developed silver image is in contact with a rod of iron or aluminium.  When copper is to be deposited, activation may be effected solely by a short physical development with silver or, in an Example (2), this is combined with the secondary reaction of the photo-sensitive compound so that the latter after exposure is treated with an acidified mercurous nitrate and silver nitrate solution also containing a developer.  Images activated by silver physical development may be rinsed with ammonia or ammonium chloride solution and platinum metalactivated images may be rinsed with alkali-metal chloride solution before the deposition of copper, nickel or cobalt.  The solution to deposit copper may contain copper sulphate, formaldehyde and preferably ethylene diamine tetracetic acid, triethanolamine or an alkali metal tartrate.  The nickel and cobalt solutions contain the metal chlorides and a hypophosphite reducing agent and preferably sodium citrate and ammonium chloride. The solutions may also contain sodium or potassium hydroxide and glycollic acid.  The photosensitive compounds mentioned include silver halides, mercuric compounds, diazo compounds such as diazosulphonates and naphthoquinone and anthraquinone mono- and di-sulphonic acids. Carriers specified are partially hydrolyzed cellulose ester films.
