Title: Device for milling longitudinal grooves or slots in wooden workpieces
Inventor: ECHTERNKAMP GUNTER
IPC: B23Q7/00
Filed: 1967-02-02
Abstract: 1,118,390. Woodworking. F. MEYER & SCHWABEDISSEN. 2 Feb., 1967, No. 5162/67. Heading B5L. A device for milling limited longitudinal grooves or slots in a wooden workpiece 2 which is fed in the direction of the groove or slot to be cut comprises a milling tool 3 which can be coupled to the workpiece while the workpiece is being fed and during insertion and withdrawal of the tool, the tool having a drive which imparts a lag thereto in the feed direction between its insertion and withdrawal. The milling tool is carried by a device 1 movable horizontally parallel to the direction of movement of the workpiece in a stationary part 4. A slide 6 having adjustable catches 7 engageable by the workpiece is coupled to the device 1 for movement therewith by a pin 10 engaging a slot in a lever pivoted to the device and having a roller 12 bearing against a guideway 13 having horizontal and inclined portions 14, 15. In operation, as the workpiece advances it engages catch 7 to advance to slide 6 and the device 1. During this movement the roller 12 runs along guideway portions 14 and the tool 3 is lowered into the workpiece, the tool and workpiece moving at the same speed. When the roller engages the inclined portion, the device 1 lags so that the tool cuts a slot in the workpiece to a length determined by engagement of the slide 6 with an adjustable stop 16 so that the tool and workpiece move at the same speed while the tool is raised whereupon the catch 7 is also raised to permit the workpiece to advance to the next catch, a spring 5 returning the device 1 to its initial position.

Title: Process for the fixation of effects mechanically produced on textile materials
IPC: D06M15/423
Filed: 1954-02-23
Abstract: Mechanical effects are fixed upon cellulose textile fabrics, especially those of regenerated cellulose, with the aid of a water-soluble alkyl ether of a urea-formaldehyde condensation product containing, per mol of urea, more than 2 mols of formaldehyde.  The ether may be obtained by reacting the condensation product of 1 mol of urea and 3 to 5 mols of formaldehyde, from which excess formaldehyde and water have been distilled, with methanol in the presence of hydrochloric acid, after which reaction the acid is neutralized and excess methanol is distilled off.  The ether is applied in aqueous solution which may also contain a condensation product of formaldehyde with guanidine, biuret, dicyandiamide, benzoguanamine, acetoguanamine, formoguanamine or melamine or water-soluble ethers of these products, and/or polyvinyl alcohol or partially hydrolysed polyvinyl acetates.  The composition may also include a hardening catalyst, coagulatable proteins, dyestuffs, dyestuff components, pigments or softeners.  In examples (1) and (2) viscose rayon fabrics are impregnated with an aqueous solution containing lactic or tartaric acid and the ether obtained by reacting methanol with the condensation product of 1 mol of urea and 4.5 mols of formaldehyde, and the fabrics are dried, chintzed or embossed and then heated to cure the resin.  In examples (3) and (4) viscose rayon fabrics are similarly treated, the aqueous solution containing, in addition to the ether, a water-soluble methylol melamine containing about 2 methylol groups, a water-soluble methylol melamine containing about 4 methylol ether groups, polyvinyl alcohol, urea, calcium chloride and boric acid.

Title: Circuit arrangement for the generation of a control voltage for the automatic amplification control of television receivers
IPC: H04N5/52
Filed: 1952-02-29
Abstract: 712,292. Automatic gain control. STANDARD TELEPHONES & CABLES, Ltd. Feb. 29, 1952 [March 24, 1951], No. 5370/52. Class 40 (5) In a television receiver for signals of the negatively-modulated type an automatic gain control (A.G.C.) voltage is derived as the sum of two voltages, the first of which is proportional to the mean value of the rectified I.F. signal and the second to the difference between the peak and mean values of the rectified video-frequency signal. The signal detector 2 is direct-coupled to a video-frequency amplifier . 6 which modulates the cathode of the picture tub'e 8. A negative going voltage proportional to the mean value of the demodulated signal is obtained by means of a resistance-condenser combination 4, 5 and appears across the condenser 5. The signal applied to the cathode of the tube 8 is also applied to the grid of a synch-separator valve 11 via blocking condenser 9: the valve 11 operates by virtue of grid-leak bias, a series grid resistance 12 also being provided to improve the elimination of noise impulses. A voltage proportional to the difference between the peak and mean values of the composite video-frequency 'signal is obtained from the grid of the valve 11, by means of resistance-condenser combination 14, 5. This voltage appears across condenser 5, being added to the first component of A.G.C. voltage ; resistances 14, 4 provide a voltage divider whereby the correct proportion of the second component of A.G.C. voltage is added in. By deriving the A.G.C. voltage in this manner, the effect of noise impulses upon the control is minimized.

Title: Subscribers line scanning arrangement
IPC: H04Q3/00
Filed: 1974-02-07
Abstract: 1423092 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 7 Feb 1974 [12 Feb 1973] 5679/74 Heading H4K A line loop detector comprises a diode/ capacitor circuit coupled to the line and effective upon an associated diode gate under loop conditions so as to permit the passage of pulses from a signal source to a detector circuit. The main purpose of the gate is to prevent spurious line signals, particularly longitudinal currents and voltage pulses, from inadvertently actuating the detector. Each line has its line wires a, b coupled via respective resistors R4, R3 to an individual diode D1 located at a crosspoint of an identification matrix M. The diode is connected on the one hand via a first capacitor Cl to a pulse source SC individual to the relevant vertical of the matrix and on the other hand via a second capacitor C2 and a gate D2, R5 to a detector circuit RC individual to the relevant horizontal of the matrix. When the line is unlooped, D1 is reverse biased, Cl is uncharged and C2 is charged. In these circumstances, pulses from SC cannot pass through the gate. The pulses are produced by momentarily saturating transistor TR1 by means of short pulses on its base terminal IN from a not shown scanner. When the line is looped, the diode Dl is negatively biased such as to permit Cl to charge and C2 to discharge and then charge in the reverse direction. Consequently an earth pulse from SC is now effective to allow current to flow through gate D2 and hence to turn-on the detector transistor TR2 which thereby provides a line loop indication at its output terminal.

Title: Improvements in or relating to train control systems

Abstract: 351,071. Track apparatus for stoppingtrains. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, and HUDD, A. E., 947, West Van Buren Street, Chicago, U.S.A. March 17, 1930, No. 5680/31. Divided on 351,039. [Class 105.] The apparatus described is the same as that of Specification 351,039 the claims being directed to the control apparatus which acts in conjunction with the stop signal. According to the present invention a train control system comprises two track elements arranged crosswise with respect to each other and with their mid points lying over each other in the mid line of the track, one element always being effective to exert a control influence, and the arrangement is such that if this element only is active it exerts a control to bring about a brake operation but if the second element is also active this exerts a second control which prevents the brake operation. The train apparatus comprises two receiving devices situated crosswise with respect to each other and with their mid points overlying each other in the mid line of the locomotive and the arrangement is such that if one device is operated, the brakes are operated, but if the second device is also operated it prevents the first device having any effect. In the apparatus shown the track elements acting in conjunction with the stop signal S comprise a longitudinal permanent magnet 51 and a transverse electromagnet 52 with their mid points lying over each other in the mid line of the track. The permanent magnet element acts on a pair of longitudinal flux collecting plates 6, 7 and the electromagnet, energized when the stop signal is at clear, acts on a pair of transverse collecting plates 4, 5. An armature 3 normally abuts against polepieces on the plates 4, 5 and is therefore not moved when both pairs of plates are activated. Should, however, the stop signal be at danger the track electromagnet is not active and therefore the track permanent magnet effects movement of the armature which moves a thin metal strip 63 to uncover a venting port 92 in a vacuum pipe system leading to a diaphragm 11 which is therefore released to open a train pipe valve 66 giving a full brake application. The armature 3 can be reset, when the train is at rest to allow access to an acknowledging key APF, by operating the key to connect the vacuum system to the under side of a spring- pressed plunger 8 having a stem to engage the armature ; the acknowledging key APF cannot be held over as a port 14 opens the vacuum system to atmosphere. The collector plates 4 .. 7 are housed in a casing 98 which has its opening to atmosphere 93 in a position to prevent dirt entering the casing.
