IPC: G03B15/04
Filed: 1967-05-17
Abstract: 1,190,663. Camera with synchronized flashlight exposure. AGFA-GEVAERT A.G. May 17, 1967 [May 20, 1966], No.22954/67. Heading G2A. A photographic camera having a shutter synchronized for flash-light exposure comprises in that part of the current circuit connected to the flash terminals 2 which is integral with the camera and to which the flash-light apparatus may be attached, a thyristor 1 to the grid of which is attached a coil 3 and a movable shutter blade with soft iron peg 6 being so arranged as to effect a variation of magnetic flux in the region of said coil, during run down of the shutter, the e.m.f. induced in said coil being sufficient to render the said thyristor conductive. In the embodiment described the coil is wound on one arm of a permanent horseshoe magnet 5, the peg 6 on run down of the shutter passing between the poles of said magnet and the shutter blade is arranged to make consecutive exposures of a shutter aperture by movement in opposite directions, the horseshoe magnet being so positioned in the path of said peg that during the two movements of the shutter blade in opposite directions the said peg initially enters between the poles of the magnet in respective positions of the shutter blade that are symmetrical with respect to the shutter aperture, the width of the pole shoes of the magnet being dimensioned in accordance with the shutter speed to allow for an appropriate ignition delay of flash apparatus to be used with the camera. Any negative pulse arising through return of the shutter blade is suppressed by diode 4. Such a diode would not be necessary with a pivoted blade shutter.

Title: Process for the separation of the cardio-active glucoside of bulbus scillae into two components
IPC: C07G3/00
Filed: 1927-09-01
Abstract: 300,726. Ellis, R.E., (Chemical Works, formerly Sandoz). Sept. 1, 1927. Glucosides. - The cardioactive glucoside of Bulbus Scillae is separated in the presence of aqueous media into two components by processes of fractional dissolution, fractional precipitation or fractional extraction from aqueous media by means of organic solvents. The separation may be effected using the actual glucosides or their compounds with tannin. In one example, a solution in methanol of the pure glucoside prepared for example according to Specification 199,400 and 217,247 is poured into water whereby the less soluble component is precipitated. After the tannin-like impurities have been removed from the filtrate by adding a precipitant such as freshly prepared lead hydroxide and filtering, the solution of the more soluble component is extracted with ether and evaporated in vacuo. According to a second example, pulverized dry Squill is extracted with alcohol and the solution evaporated. The residue is dissolved in water, common salt added and the solution extracted with ethvl acetate. The ethvl acetate extract is evaporated and the residue taken up with water to which common salt solution has been added, whereby the more soluble component goes into solution, leaving the less soluble component as a flocculent precipitate. The latter is separated, dissolved in aqueous alcohol and freed from tannin by treatment with lead hydroxide or the like. The more soluble component is similarly treated and worked up as in the first example. According to a third example, an extract of Squill prepared as in the previous example is dissolved in methanol, treated with chloroform and filtered. The solution is evaporated and the residue stirred with water containing common salt. The less soluble component is separated and worked up as an in example 2. After removing tannin from the solution of the more soluble component, acid impurities are removed by adding sulphuric acid and extracting them with chloroform. The neutralized solution is saturated with ammonium sulphate and the glucoside extracted with ethyl acetate. The glucosides, on hydrolysis with mineral acids, give one molecule each of glucose, rhamnose; and the aglucone.

Title: Pulsimeter
IPC: A61B5/024
Filed: 1976-06-03
Abstract: 1524413 Pulsimeter HEUER LEONIDAS SA 3 June 1976 [4 June 1975] 23041/76 Heading G1N(E) In a pulsimeter which may be worn like a wristwatch, the output signals from a pulse sensor 7 are supplied to a signal processing circuit 10 wherein "n" squarewave pulses are generated for each pulse beat. The resulting squarewave pulses are fed to a counter circuit 15 which counts the number of pulses occurring in an interval 60/n seconds. Thus the number shown on a digital display 5 is an extrapolation of the number of pulse beats per minute. Circuit details The output signal of the sensor 7 is directed via a pulse shaper 11 to an integrator 12a whose voltage output is directly proportional to the interval T between the pulse beats. This voltage signal is fed to a voltage sensitive oscillator 12b that produces "n" pulses in the interval T of the pulse beats. These pulses are supplied to one input of an AND gate 14. The other input is supplied by an auxiliary counter 13 supplied by the shaper 11 and the oscillator 12b. The auxiliary counter and the gate 14 function together to prevent the counting of more than "n" pulses from the oscillator following a heart beat in the event that the succeeding heart beat is delayed or missed, and so "skipped" beats will be noticed by the resulting effect on the display 5. The signals from the gate 14 pass to a three stage counter 16. The counted values are transferred to a memory 17 containing a series of shift registers 17 every 60/n seconds. The transferance is controlled by a signal derived from an oscillator 19 supplying a frequency divider 20, a "negative jump" differentiator 21 and a "positive jump" differentiator 22. The memory 17 is connected to a display control 18 which scans the memory at a rate determined by the oscillator 19. The display consists of light emitting diodes that are activated when a button 6 is depressed. A further diode 5a may also be connected to the pulse shaper 11 so that it flashes in rhythm with the pulse beats.

Title: Improvements in the separation of proteins and lactose from whey or similar liquids
IPC: A23J1/20
Filed: 1922-08-25
Abstract: In treating whey from cheesemaking and similar liquids from other milk-treatment processes to obtain lactalbumen and lactose, the whey is first neutralized with a slightly soluble oxide or carbonate, such as magnesia or chalk, and the albumen is precipitated without concentrating the whey by means of carbon dioxide and aluminium hydrate, which may be generated in the whey by adding chalk and aluminium sulphate.  The two steps may be combined in one, but if it is desired to obtain the lactalbumen in as pure a state as possible the whey is first neutralized, heated to 80 DEG -85 DEG  C., filtered from the coagulated albumen, and then treated with the aluminium hydrate and carbon dioxide to precipitate the remaining albumen. Specification 13444/90, [Class 127, Sugar], is referred to.

Title: Improvements in electric fusion welding
IPC: B23K9/18
Filed: 1944-11-24
Abstract: 579,186. Uniting by fusion. LINDE AIR PRODUCTS CO. Nov. 24, 1944, No. 23433. Convention date, Jan. 20. [Class 83 (iv)] In a method of electrically melting and depositing metal from an electrode on to a work-piece, such as armour plate, and simultaneously melting metal of the work-piece so as to coalesce therewith, heat is applied to the electrode in addition to that derived from the welding current, in an amount sufficient to increase the ratio of melted electrode metal to melted work-piece metal. Welding or the deposition of a protective overlay such as of non-ferrous or highly alloyed ferrous metal, e.g. austenitic steel containing ingredients such as chromium, nickel and manganese, on a steel base, are thus effected without deep penetration of the work-pieces, thus avoiding undue softening or hardening of the metal, and with reduction of the dilution of the electrode metal by the work-piece metal. Welding may be effected as described in Specification 433,723 with a bare electrode 10 blanketed by comminuted mineral material and connected to a source of alternating or direct current through a variable resistance 17. The additional heat to the electrode may be obtained from alternating or direct current passed therethrough between collets 14 and 15 through a variable resistance 16. It may alternatively be effected by surrounding the electrode by a coil carrying high-frequency alternating current so as to heat by induction, or by directing thereon oxyacetylene or other flame jets.
