Title: Method and apparatus for determining a statistical characteristic of a parameter subject to random fluctuations
IPC: G01B21/08
Filed: 1965-10-18
Abstract: 1,122,797. Statistical computing device. J. PEKLENIK 18 Oct., 1965 [20 Oct., 1964], No. 44021/65. Heading G4G. When a first parameter is subject to random variations in dependence on a second parameter, e.g. ordinal values of temperature, power, voltage against abscissal values of time, or thickness or diameter of a sheet wire or yarn against abscissal values of length; it is shown mathematically that the variations are distinguished and characterized by the standard deviation of the slope of the parameter, # x . , where # x . = # x  r a , C a ; in which # x  is the standard deviation of the variable, r a  is the number of intersections of the ascending and/or descending flanks of the curve of the variable with a predetermined level a displaced from the abscissal axis, and C a  is a constant given by where m x  is the mean value of the variable (Fig. 4). A curve X (t) representing deviations of a surface is interpreted by the displacements of a stylus in a measuring device V (Fig. 5) to produce corresponding signals which are applied to a known device R calculating a signal representing the standard deviation # x  which is indicated and also applied to a Schmitt trigger to which a bias is applied from potentiometer P representing level A; the trigger operating at points of equality between the bias voltage and the ascending flanks of the signal representing curve X (t). A counter Z registers the number of operations of the trigger, and the value r a  is indicated and converted by digital analogue converter D/A to a corresponding voltage, which may be indicated. A function generator T receives voltages representing a, m x  and # x  to compute a voltage representing C a , which may be indicated, and a multiplier M receives voltage representing # x , r a  and C a  to compute a voltage representing characteristic # x . which may also be indicated.

Title: Analyzer for nuclear spectrometry
IPC: G01N23/08
Filed: 1965-10-18
Abstract: 1,128,468. Recording nuclear energy spectra. LABEN LABORATORI ELETTRONICI E NUCLEARI S.R.L. Oct. 18, 1965 [Oct.22, 1964], No.44066/65. Heading G1A. Apparatus for recording nuclear spectra is arranged to print out one measurement whilst the next measurement is being made. An analogue to digital converter ADC, Fig. 3 produces a code corresponding to the height of a pulse UR from a particle detector, which code is passed to an address register IA. Register IA selects a corresponding channel in a ferrite core memory sub-group FCM<SP>1</SP> in which the spectrum is being built up, and the content of this channel is read into a content register CA. +1 is added to this content which is then written back into the memory sub-group FCM<SP>1</SP>. The result of a previous measurement, stored in the memory sub-group FCM<SP>11</SP> is read out by the content register CA channel by channel and transferred to a second content register CB which is used to control the acutal read out device AU (e.g. a tape or card punch, series or parallel printer or magnetic tape recorder). Since the content register has to perform a function both in classifying pulses and reading out the result of a previous measurement, a control circuit CC is provided to ensure that it is not asked to do both at once. The control circuit Fig. 2, receives pulses e at regular intervals which are passed along m<SP>11</SP> to control the reading out. When there is a pulse to be analysed, a pulse a is transmitted to m<SP>1</SP> and closes gates A 1  and A 3  to prevent transmission of any e pulses until the classification of the pulse is complete.

Title: Improvements in or relating to reversing gears
IPC: B63H23/08
Filed: 1962-11-22
Abstract: 951,038. Reverse gear and control; friction clutches. VOLVO-PENTA A.B. Nov. 22, 1962 [Nov. 24, 1961 ; Sept. 10, 1962], No. 44272/62. Headings F2C and F2D. In a forward-neutral-reverse gear for a marine outboard motor, forward or reverse opposed bevel gears 1, 2 freely carried by an output shaft 3 and meshing a driving bevel pinion fast with an input shaft, are selectively clutched to the shaft 3 by a double-ended slidable friction cone clutch member 7 helically splined on the shaft 3 to provide a self-tightening action on clutch engagement. The clutch member 7 is normally engaged by a spring with the forward drive bevel 1 and controlled by two electromagnetic devices 12, 14 which when energized, respectively serve to disengage the clutch member 7 and engage it, against the spring bias, with the reverse bevel 2, the member 7 being formed with a central groove 9 provided each side with inclined cam surfaces 11. On energization of the magnet 12, a pin 13 moves radially inwards to engage one of the cam surfaces 11 whereby the member 7 is moved to a central neutral position and locked there by further penetration of the pin 13 into the groove 9. Reverse is engaged by energizing the magnet 14, or operating a manual lever 16, to turn an eccentric pin 15 permanently engaging the groove 9, which moves the clutch member 7 into engagement with the reverse bevel 2, the pin 13 being withdrawn when the pin 15 starts to rotate, the control devices 12, 14 being electrically interconnected to prevent the pin 13 locking the member 7. The spring 8 may be omitted in which case the clutch member 7 by its own weight engages the bevel 2 for forward drive, reverse then being effected through the bevel 1, the input shaft being driven in the opposite direction to the former arrangement or, a reversible pitch propeller is used. In Fig. 4 the clutch member is controlled solely by an eccentric pin such as 15, Fig. 1, the rock shaft 31 of which is turned by manually rocking a shaft 34 having an eccentric 35 engaging a V- groove in the shaft 31 through a spring loaded ball 40 which serves to resiliently maintain the shift device in either extreme engaged position whilst the manual rock shaft can be further rotated to perform additional functions such as to increase the engine fuel supply. In Fig. 6, the shaft 41 carrying the eccentrically mounted clutch shift pin is rotated by a forked arm 42 operated by a control lever 43 through a link 44 spring loaded against the bottom of the forked arm such that, as before, on further rotation of the operating lever beyond that required for clutch engagement, the rod rides up the slot of the lever against the spring bias.
