Title: Improvements in or relating to a process and apparatus for sizing filaments
IPC: D01G29/00
Filed: 1962-06-18
Abstract: 1,002,570. Sizing and winding filaments. FARBWERKE HOECHST A.G. June 18, 1962 [June 20, 1961], No.23368/62. Headings D1J and D1L. A filament, e.g. a synthetic filament drawn from a bobbin 1 is passed through a guide 2, through a thread brake 3 and over a guide pin 4 to be sized by a smooth or grooved roller 6 rotating in a bath 5 of the sizing agent: the filament is then guided by rollers 7, 8, 9 through air for 6 to 17 feet to allow the size to dry at least partially and is then wound up on a cheese 15 in such a way that the traversing guide 10 and its supporting frame 17 do not contact the filament on the cheese. As shown the traversing guide frame carries a light 11 and a photo-electric cell 12 such that as the cheese grows to interrupt the light beam an electric motor 13 is acutated to shift the frame via a worm gear and hold the guide 10 out of contact with the cheese. In a further form the frame carrying the traversing guide is shifted by a cam which is rotated in accordance with the number of revolutions performed by the cheese, the cam shape depending upon the thickness of the filament being wound. Alternately the cheese may be moved away from the traversing guide. The size in tray 5 is fed from a storage tank and is preferably recycled and filtered.

Title: Automatic flash control device for photographic cameras
Inventor: HUTCHISON MILLER REESE
IPC: G03B15/04
Filed: 1963-06-13
Abstract: 1,018,246. Photographic flash guns. EASTMAN KODAK CO. June 13,1963 [Aug. 6, 1962], No. 23543/63. Addition to 968,932. Heading G2A. A modification of the invention claimed in the parent Specification consists in providing an electromagnetic device 54 which controls the actuation of the switching device. As shown, the device 54 is a relay coil in series with a photoresistive cell 36. Relay coil 54 is energized by battery 24 when switches 26 and 28 are closed. Control switch 56 is then opened to connect cell 36 into the relay circuit. If the field brightness is high, a high current flows through cell 36 thus energizing relay 54 such that switch 58 is held open to interrupt the circuit to lamp 20. If the brightness is low relay energization is too low to open switch 58 so the lamp 20 is fired when shutter synchronizing switch 28 is closed. In a modification, Fig. 2 (not shown) a sensing member 68 having stepped surface 70 is moved manually upwards to engage pointer 66 of galvonometer 62 thus setting an exposure aperture formed by blades 72, 74. Switch contacts 84, 86 are closed to complete a lamp circuit when member 68 moves upwards sufficiently to open the aperture to compensate for low level of brightness.

Title: Improvements in photometers and like photoelectric instruments
IPC: G01J1/36
Filed: 1946-08-09
Abstract: 668,362. Photo-electric flicker photometers; electromechanical impedances. SIGRIST, W. Aug. 9, 1946, No. 23607/46. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 11, 1947.] Classes 40 (iii) and 40 (viii). [Also in Group XL (c)] An electric flicker photometer comprises an optical member electromechanically oscillated at a predetermined frequency to project the images of two illuminated objects to be compared on to a photo-cell, to produce an A.C. at the oscillation frequency, whose amplitude corresponds to the difference of light intensity between the objects, which is applied to a demodulator network energized by a steady A.C. from the electromechanical oscillator, converted into a slowly varying indicator signal corresponding to the light intensity difference, and applied to a measuring instrument through a low,pass filter admitting only a restricted frequency band. In Fig. 1 a lens L and oscillating mirror S project images A<SP>1</SP>, B<SP>1</SP> of the illuminated surfaces A, B to be compared on to a screen C having an aperture C<SP>1</SP> through which a photocell Ph is alternately illuminated to produce an alternating signal at the oscillation frequency which is amplified at IV and fed to the half-wave or full-wave ring rectifier demodulator V together with a steady energizing A.C. derived from the mirror oscillator system II, III, in which a resonator (Fig. 3) comprising a flat spring F pivoted at nodes F<SP>1</SP>, F<SP>2</SP> and carrying at its centre a mirror S balanced by weights M<SP>1</SP>, M<SP>2</SP>, M<SP>3</SP>, M<SP>4</SP> is arranged to oscillate about the nodes when driven by an armature X disposed in the common air-gap of two magnetic windings Y<SP>1</SP>, Y<SP>2</SP> which are connected in the opposite arms of a bridge network, Fig. 4 (not shown), having chokes for the remaining arms and energized by an amplifier valve through a transformer, the valve control electrode being energized regeneratively by the bridge unbalance to maintain continuous oscillations of the mirror at the natural frequency of the resonator. The demodulator output supplies a slowly varying indicating signal, corresponding to the varying light intensity difference between A and B, to a measuring instrument VII through an end amplifier VI and a lowpass filter limiting the response to a restricted frequency range to exclude spurious indications and background interference. The filter may comprise RC elements, or the response limitation may be accomplished by the inertia effect of the measuring instrument. The resonator may be excited piezo-electrically or electrostatically.

Patent GB-814636-A (GB)
Title: Novel unsaturated alcohols and esters thereof and a process for the manufacture of same
IPC: C07C33/02
Filed: 1957-07-29
Abstract: The invention comprises unsaturated alcohols of formula <FORM:0814636/IV (b)/1> and esters thereof with organic aliphatic carboxylic acids; R represents an alkyl group containing 2-4 carbon atoms.  The preferred esters are those formed with lower aliphatic carboxylic acids, "lower" meaning containing up to 6 carbon atoms. The esters of the above alcohols may be prepared by halogenating with concentrated aqueous or anhydrous hydrogen chloride or bromide or with a phosphorus halide an alcohol of formula <FORM:0814636/IV (b)/2> with concomitant allyl rearrangement to the halide of the alcohol of the first formula above, and converting the latter to the corresponding ester by treatment with (i) an alkali metal salt of an alkanoic acid, or (ii) with an organic aliphatic carboxylic acid anhydride in the presence of a lower alkanoic acid. Alternatively the 3-alcohol above may be acylated with an organic aliphatic carboxylic acid anhydride (or by other methods known per se) and the 3-ester heated with a lower alkanoic acid to effect rearrangement.  The free 1-alcohol may be obtained by hydrolysis of the 1-ester, e.g. with an alkali metal hydroxide and may if desired be re-esterified, e.g. by treatment with an organic acid anhydride in the presence of pyridine. In examples the acetic acid esters of 3,7-dimethyl-nonadien - (1,6) - ol - (3) and 3,7,9 - trimethyl-decadien - (1,6) - ol - (3) are prepared, the free alcohols obtained by hydrolysis, and the isobutyric acid esters prepared by acylation with the anhydride.  In Example (1) the starting 3-alcohol is prepared by chlorinating 3-methyl-penten-(1)-ol-(3) to give the 3-chloro-compound, condensing the latter with ethyl acetoacetate to give 3 - carbethoxy - 6 - methyl - octen - (5)-one-(2), hydrolysing the ester with KOH to give the K salt of the free acid, treating with concentrated HCl to effect decarboxylation and produce 6 - methyl - octen - (5) - one - (2), adding an acetylene in the presence of sodamide to yield 3,7 - dimethyl - nonen - (6) - yn - (1) - ol-(3) and hydrogenating catalytically to produce 3,7 - dimethyl - nonadiene - (1,6) - ol - (3).  In Example (2) the starting 3,7,9-trimethyl-decadien - (1,6) - ol - (3) is prepared analogously from 3,5-dimethyl-hexen-(1)-ol-(3).

Title: Wave soldering of circuit components to electrical circuit boards
IPC: B23K3/06
Filed: 1959-07-13
Abstract: 862,722. Soldering. SYLVANIA ELECTRIC PRODUCTS Inc. July 13, 1959 [Aug. 26, 1958], No. 24043/59. Class 83 (4). In applying molten solder to the underside of a circuit board having depending component terminals to solder the terminals to circuit conductors on the said underside of the board, a wave of solder is formed by forcing molten solder up through a slot-like orifice, the orifice having an overflow apron of gentle inclination extending along one side, and the circuit board is passed transversely across the crest of the wave from the side remote from the apron whereby in passing across the apron the terminals emerge gradually from the solder. Molten solder 11, Fig. 1, e.g. 60% tin, 40% lead, is pumped through an aperture 13 in a submerged plate 15 up through an orifice formed by an end plate 16, an opposite end plate and side plates 38, Fig. 2. The end plate 16 has an abrupt overflow lip 19 with falloff skirt 21 and the opposite plate has an overflow apron 17 with a linear gradual decline between the lips 23 and 24, the solder forming a wave which rises to a crest 30 to overflow over both apron 17 and skirt 21 to return to the reservoir. Endless flexible e.g. synthetic rubber belts 39, Fig. 2, guided in slotted side blocks 41 drive printed circuit boards 31 from left to right in Fig. 1 over the top edges of the side plates 38 to pass over the solder wave so that terminals 33 are brought into contact with the solder. The skirt 21 and apron 17 can be bent to vary the rate of immersion and emersion of the terminals. The reservoir has insulated side walls 53, Fig. 3, and a bottom plate 55 with an orifice 61 in communication with a radial pump 63 which pumps solder through an aperture 87 against a baffle plate 88 and then up through a tapered conduit 89 to the top of which is secured the plate 15. Heaters are suspended in the reservoir and may be inserted in apertures 83 in the base.
