Filed: 1955-10-05
Abstract: 785,253. Reservoir pens. GRUBE. F., [trading as,KAWECO, BADISCHE FULLFEDERFABRIK F. GRUBE]. Oct. 5, 1955 [Oct. 5, 1954], No. 28423/55. Class 146(3) In a ball-point pen of the kind wherein the writing unit is retractable within an outer casing, there are two writing units 1, 2 arranged co-axially in a removable double sleeve 3 so that when the reservoir of one unit is exhausted the other unit can be brought into use by reversing the units. The unit 2 is shorter than the unit 1, and may have the same or a differently coloured ink therein. The sleeve 3 has a transverse wall 4 with conical recesses 5, and lateral holes 6 allow air to reach the reservoir of both units. In use, a cap 8 is fitted over the point of the unit 2, and the usual retracting spring 7 is fitted over the unit 1 to abut the end of the sleeve 3 before the units are inserted in an outer casing (not shown). The point of the unit 1 is moved from the casing into writing position on depression of a push stud. When the unit 1 is empty of ink, the units are removed from the casing, the spring 7 removed and pushed over the unit 2, and the units re-inserted into the casing in the reverse order.

Abstract: 1,212,041. Continuous sol production. UNIVERSAL OIL PRODUCTS CO. 18 June, 1968 [21 June, 1967], No. 29009/68. Heading C1A. A metal oxide sol is produced continuously by reacting, in a digestion zone, an excess of particles of aluminium, chromium, iron, zirconium; zinc, gallium, or mixtures thereof, with a mixture of hydrochloric acid and recycled sol by passing the mixture through the digestion zone at a superficial linear velocity (defined as volume flow rate over area of digestion zone when empty) of at least 31 cm/minute and continuously removing part of the resultant sol at a rate such that the average residence time of the sol in the digestion zone is from 1 to 12 hours, the remainder of the sol being recycled. The linear velocity of the acid/sol mixture in the digestion zone may be as high as 610 cm/minute. The temperature in the digestion zone may be 52‹ C. to 121‹ C., and pressure may be applied to maintain the sol/acid mixture in the liquid phase e.g. by controlled venting of the hydrogen by-product. In the case of aluminium the product is an alumina sol containing chloride. The aluminium content (preferably less than 14%), chloride content (preferably 8-12%) and aluminium/ chloride ratio (usually 0À5 to 2 by weight) may be controlled by varying the rates of addition of the various reactants and the rate of sol product removal.

The hydrolysed product from step (a) may be subjected to processing, e.g. the removal of water and acetic acid, of unreacted or only partially hydrolysed starting material, before the treatment of step (b). Treatment (b) removes from the mixture acidic material washed off the cation exchange resin that unfavourably affect the stability of the diols, particularly in the subsequent fractionation. The process is -particularly suitable for the preparation of the 1,4-diols from the corresponding diacetates, though it may also be used to obtain other butane or butene diols; the starting materials may be obtained by oxidative acetoxylation of butadiene with acetic acid, optionally followed by hydrogenation. The cation exchange resin is preferably a sulphonic resin based on styrenedivinylbenzene, and the anion exchange resin a strongly or weakly basic amine based on a polyacrylate or polystyrene matrix.

Abstract: 1391351 Pneumatic braking systems; brake warning devices FABBRICA ITALIANA MAGNETI MARELLI SpA 21 June 1972 [25 June 1971] 29155/72 Headings F2E and F2F In a vehicle compressed air braking system an actuator C is locked in the parking position only when the service braking pressure is a maximum. As shown, service braking takes place on actuation of a pedal operated distributer D, air passing from a reservoir S 1  to advance actuator piston 1. Pressure air also passes via conduits 27, 28 to a valve 8 on piston 24 of which is depressed against the action of a spring 25 when the maximum pressure is reached. An extension 31 is thereby freed from a groove 33 of a hand operated member 12 which is thereby permitted to move rightwardly allowing a valve stem 13 to move upwardly under the action of springs 13, 20. A valve member 14 is thereby seated to cut off communication, via lines 16, 18 between a reservoir S 2  and a piston 5 located in a lock actuator chamber, further upward movement of member 14 allowing the chamber to be exhausted through the hollow interior 21 of the stem 13 and outlet 22. A spring 7 in the chamber pivots a member 6 to an inclined position locking the stem 3 of the actuator C. A brake warning device is provided comprising pressure switches I 1  and I 2  respectively open when no pressure exists in line 28 and pressure exists in line 18, lamps L 1 , L 2 , a relay R, a flasher unit T and an ignition switch contact connected through a contact K of relay R to a voltage supply (+). When the ignition key is inserted, contact K being at point a, with the parking braking on and no pressure in line 18, lamp L 1  flashes. When the release operation commences conduit 28 is pressurized, switch I 1  closes so that lamp L 2  is continuously lit.

[Class 38 (v)] [Also in Group XXXIX] A signal-responsive re lay modifies its circuits on operating to prevent its being held, after the cessation of the signals, by noise currents of a level approaching that of the weakest effective signal. For example, it may interact with a further relay which, by opening its circuit or cutting in a reverse winding, causes it to be intermittently released, Figs. 1 and 3 (not shown). Alternatively it may, with the aid of a further relay cause the reversal of current through or the short-circuiting of a winding which helped its initial operation, Figs. 2 and 4 (not shown). As shown, the relay B in response to rectified signal current energizes E which reverses the direction of current through the right-hand winding of B and so tends to make it or actually makes it drop back.

Abstract: 989,884. Detecting characteristic marks on letters. STANDARD TELEPHONES & CABLES Ltd. Aug. 16, 1961 [Aug. 18, 1960], No. 29602/61. Heading B8A. Documents, e.g. letters, are examined for the presence of a characteristic mark, e.g. a stamp. The letter on a conveyer (not shown) is scanned by a photo-cell device 1 the output of which measures the reflection coefficient of the part of the document scanned and is thus modulated by the presence of a stamp. The output is fed via an amplifier 2 to a first amplitude filter 6 designed to produce an output for signals corresponding to reflection coefficients less than 65% and simultaneously to a high-pass filter 10 which removes the D.C. component. The amplitude filter 6 transmits so long as the input signal corresponds to less than 65% and marks its output, and thus the input of time integrating circuit 7 which, when it reaches a certain time corresponding to the width of a postage stamp transmits a setting signal to storage device B which thus marks its output and one of the inputs of an AND-gate F. The high-pass filter 10 passes the A.C. com ponent of the signal to a second amplitude filte 11 which marks one of the inputs of a second AND-gate K the other input of which is marked by the output of the first amplitude filter 6 in the presence of the appropriate signal from the photo-cell device 1. This unblocks AND-gate K which gives an output fed to a pulse-shaper 12 which feeds a standard pulse to a pulse counter 13. When a certain number of pulses are counted the output of counter 13 is marked and the storage device E is set thereby so that both inputs of AND-gate F are marked and a signal fed to a control device W (unless prevented by an AND-not gate O intended to prevent false identifications due to marking of input h). Modifications of the arrangement (Figs. 2 and 3, not shown) enable further criteria of identification to be adopted, e.g. that a portion of the document near the stamp must be brighter than the stamp and to avoid identifying printed or hand written portions as stamps.
