Title: Improvements in laser rangefinders
Inventor: KERENYI IMRE
IPC: G01S17/14
Filed: 1966-02-21
Abstract: 1,083,073. Laser rangefinders. G. & E. BRADLEY Ltd. Feb. 21, 1966, No. 7547/66. Heading H4D. [Also in Division G4] Apparatus for providing an analogue electrical signal representing the time elapsed between two events includes a counter 15 (Fig. 1), which is enabled to count clock pulses when the first event occurs and prevented from counting clock pulses after the second event, the output from the counter being converted into an analogue form. In the embodiment described for determining the position of an object the counter commences its count when a gate 13 is enabled by control circuitry 11, the control circuitry 11 also causing a laser 10 to emit a light pulse. When a reflected light pulse from the object is received by a photomultiplier in a receiver 12 the gate 13 is closed to stop the count. The binary coded decimal counter 15 then sets sixteen relays, four in each decimal stage, the relay contacts bridging binary weighted resistors connected in series. The resistors may be connected across an amplifier (32, Fig. 3, not shown), to control the gain so that the output voltage from the amplifier depends on the resistance of the combined series of weighted resistors and hence on the time between the emitted light pulse and the reflection which closes the gate 13. Alternatively (Fig. 4, not shown), the resistors (42) may be connected across a potentiometer (40) so that as the resistance varies an error signal applied to an amplifier (39) positions the wiper of the potentiometer and at the same time a pen (37) of a chart recorder. To find the position of several objects a series of counters 15, 47, 48 (Fig. 5), may be enabled by gates 13, 45, 46 when the laser 10 emits a light pulse and each gate then closed when the reflection from an associated object is received. Each counter then gives an analogue output signal corresponding to the position of one of the three objects.

IPC: B01D11/02
Filed: 1948-03-12
Abstract: <PICT:0644910/III/1> An oil - containing substance is continuously extracted with a solvent by placing it in a receptacle movable in a continuous horizontal circular path, extracting the contents of the receptacle a number of times with solvent of gradually decreasing solute content, the solvent after each extraction being applied to a succeeding receptacle and fresh solvent being added to each receptacle whilst in its last position but one.  The process is effected in an apparatus comprising a plurality of receptacles R1-R8 attached to a rotatable vertical spindle 3, each receptacle being provided with a combined filter bottom 12 and collecting tray 14, Fig. 3, pivotally attached along one edge to the receptacle and the other edge being supported via rollers 15 by means of a discontinuous trackway comprising two rails 17.  A charging hopper above receptacle R1 charges the receptacles <PICT:0644910/III/2> successively. Solvent is introduced from a reservoir to a sprayer S1 into receptacle R6 and collects in the collecting tank T1 beneath whence it proceeds through an outlet O1 and pump P1 to a p  sprayer S2 and similarly in succession through the tanks T2-T6, pumps P2-P5 and sprayers S2-S6 and outlets O2-O5, the strong solution having passed through the newly charged receptacle R1 being collected from an outlet O6.  A gap in the rails 17 under compartment R8 permits the hinged filter bottom and collecting tray to drop, discharging the contents of this compartment via a shoot 20.  A cranked bar 22 and counterweight 23 controls the descent of the filter bottom.  The receptacles are preferably maintained in continuous movement but with solids of high oil content, it may be preferable to make the movement discontinuous, the solids being treated with solvent which all drains into the collecting tank beneath before the receptacles are moved forward to the next position.

A method of making a milk powder comprises separating by centrifugal action the fatty phase and the non-fatty phase of whole milk or fat-enriched milk either before or after Pasteurization or uperization (i.e. high-temperature short-time sterilization e.g. by injecting steam), concentrating the non-fatty phase until it has a solid content of 40-55% by weight, heating said concentrated non-fatty phase between 70‹C. and 90‹C. for 30 to 5 mins., mixing the treated non-fatty phase with the fatty phase, homegenizing the mixture at 38‹C. to 45‹C. and then drying the homogenized mixture. The fatty phase may be melted and centrifuged to remove residual water which contains the protein membranes of the fatty globules and this residual water is then added to the non- fatty phase before concentration thereof. The fatty phase may be deodorized by distilling under reduced pressure. The deodorization step may take place after the removal of the residual water. The non- fatty phase may be concentrated in vacuo in a thin film continuous concentrator. The mixture may be homogenized using a piston homogenizer. The homogenized mixture may be freeze-dried or spray-dried.

Abstract: 590,242. Measuring pulse duration. STANDARD TELEPHONES & CABLES, Ltd. April 5, 1945, No. 8486. Convention date, March 26, 1943. [Class 40 (v)] [Also in Group, XXXVI] For measuring the duration of recurrent substantially rectangular pulses, 15a, a resonant circuit L, C, is shock excited by the leading and trailing edges of the pulses. The first half wave of the combined oscillation produced after the occurrence of the trailing edge is arranged to reach a maximum peak value, indicated by a meter 34 fed from a class C amplifier 30, by adjustment of condenser C which determines the resonant frequency of the tuned circuit. The condenser C settings are calibrated in pulse width, the maximum reading of the meter 34 occurring when the pulse period is half the period of the tuned circuit. The valve 20 is provided to damp the tuned circuit, except when it is blocked by the pulse voltage applied to its grid from resistance R and also during the positive half-wave following the occurrence of the trailing edge which biasses the cathode. The pulse voltage is also applied to disable the amplifier 30, through lead 55, to prevent its operation by any subsidiary maxima during the pulse period, produced when the circuit LC is tuned to a frequency higher than the critical value. The circuit may be modified to use minimum instead of maximum indications.
