Abstract: 690,424. Agricultural implements. MONROE AUTO EQUIPMENT CO. June 23, 1948 [Feb. 14, 1948], No. 16888/48. Class 6(i) [Also in Group XXIX] An implement such as a plough 29 is attached to a "Jeep" type vehicle 13 having either a two-wheel or four-wheel drive, by means of lower converging links 25 and an upper compression link 33, the length of which is adiustable by means of a turnbuckle 32. The links 25 are universally connected to a hitch bar 23 and the rear ends of the links are universally connected to the plough. The link 33 is universally connected to a housing 35 and to the plough. The implement is lifted and lowered by means of a hydraulic jack (not shown), which is located within the housing 35. The jack is connected by a lever (not shown), to a shaft 71 which rocks levers 59, 69 connected to links 25 by links 53, 63. The link 53 can be adjusted in length by turning a handwheel 47. A power take-off shaft 45 may be driven by the vehicle engine whether or not the ground engaging wheels are being driven. It may be used with post-hole diggers or power-operated saws. An adjustable relief valve is provided in the circuit associated with the hydraulic jack so that the pressure on the jack piston can be relieved thus leaving the piston free in its cylinder. Under such conditions the depth of operation of the plough is completely controlled by either a depth control wheel 43 or the adjustable turnbuckle 32. The front wheels of the vehicle take 40 per cent approximately of the load from the plough while approximately 60 per cent is taken by the rear wheels. A downward pressure can be applied to the plough by adjusting a control valve 161, which controls the supply of liquid to the jack, to its implementlowering position. The invention can also be used with cultivators.

IPC: B60T11/22
Filed: 1956-06-02
Abstract: 859,911. Hydraulic brakes. GIRLING Ltd. June 3, 1957 [June 2, 1956], No. 17120/56. Class 103(1). In a master cylinder of the kind in which a port in the end of the cylinder remote from the working piston is connected to a reservoir and is adapted to be closed by a valve when the system is under pressure, a frictional sliding coupling is provided between the working piston and a rod attached to the valve controlling communication between the cylinder and the reservoir when the piston is advanced to apply pressure to the system the valve is moved forwardly, as a result of the frictional coupling, into engagement with its seating to close the valve independently of the fluid pressure in the cylinder without reliance on spring-loading of the valve. In the embodiment illustrated, a master cylinder 10 has formed integrally therewith a fluid reservoir 11 which is in communication with the cylinder bore 12 of the master cylinder by way of axial opening 13; the opening and closing of said axial opening being controlled by a valve member 31 provided on the end of an axiallyextending split rod 26 which slides into an axially-extending recess 24 in the master cylinder piston 18. The length of the rod 26 in relation to the other dimensions of the assembly is such that when the piston is fully retracted and the valve 31 is open in engagement with a cage 35 abutting against the end of the cylinder, the head 25 on the rod is in frictional engagement, with the wall of the recess 24 and is in engagement with the flange or lug 28 on a thimble 29 surrounding inwardly-extending spigot 22 of piston 18, the parts being in the position shown in Fig. 1. In operation, when piston 18 is moved to the left to pressurize the brake cylinders via connection 17, the frictional coupling between rod 26 and piston 18 causes the valve to move with the piston until the valve engages its seating and cuts off the reservoir from the cylinder. The rod 26 can then telescope into the piston as the piston advances. On the return movement of the piston the valve opens as soon as the piston starts to move and the pressure in the cylinder falls, but if the valve should stick and fail to open it will be positively opened by the engagement of the flange or lug 28 with the head 25 on the rod 26 when the piston returns to its fully retracted position.

Abstract: 660,726. Automatic exchange systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 29, 1949 [July 2, 1948], No. 17209/49. Class 40 (iv). A circuit for detecting the calling condition of a subscriber's line comprises resistors R1 and R4 connecting battery and earth to the line conductors a and b, respectively, and seriesconnected resistors R2 and R3 connecting the b conductor to a test wire c and to a call detector OD common to a group of lines. The change in potential across the resistors due to closure of the subscriber's loop circuit causes a normally conducting valve 7 in the call detector to become cut-off and release a relay 8 which starts a linefinder OZ over a contact 9. When the characteristic potential of the calling line is found, a control device (not shown) stops the finder and busies the outlet by applying earth potential over contact 11 to the test wire. Symmetrical loading of the line under speech conditions is arranged by making the parallel combination of resistors R2 and R4 equal in resistance to R1, which may consist of a non-linear resistance having inverse resistance/voltage characteristics. Specification 641,819 is referred to.

Filed: 1936-06-22
Abstract: 476,445. Knitting. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES. June 22, 1936, No. 17348. Convention. date, July 10, 1935. [Class 74 (ii)] Relates to a narrowing device for flat hosiery frames equipped with a jacquard for producing openwork &c. patterns, in which the narrowing comb, which extends over the entire width of a division consists of a plurality of parts displaceable with regard to one another to enable split connections to be made in a space free from narrowing points, 'while patterning, narrowing and widening are done as usual. The three parts 4, 11, and 12, into which the narrowing comb is divided, are carried by axially slidable carrier bars 3, 7, and 10 which are urged by springs 14, 16, and 19 towards stops 17 and 20 : the part 4 can, in addition, be swung up out of action when desired. These stops are slidably mounted on rods 23 and 38 and the distance of each from the carrier bars can be varied by the insertion between it and the end of the rod 23 or 38 of one or both of a pair of intermediate members, namely 31, 32, or 45, 46. The effective length of bar 3 can be increased or decreased as desired by means of an intermediate stop member. 53 which can be swung on a pivot 52 to put its end into or out of line with the end of the shaft 3. An adjustable collar 15 also limits the axial movement to the lift of the rod 3. Stepped wedges 24, 39 can be individually raised or lowered by means of axially movable stepped cams 26, 40 so moving rods 23, 38 axially, and hence moving laterally to the extent of one or two needle spaces, those sections of the narrowing comb whose carrier bars abut against the stop or stops 20, 17 moved. 'To effect patterning the parts 4, 11, 12 are united to form a single comb. In this position the intermediate members 32, 46, are in front of their rods 23, 28, and the intermediate stop 53 is swung down into the active position, with the result that the carrier bars 3 and 7 abut against the stop 17, and the carrier bar 10 abuts against the stop 20. By means of cams 26, 40, the parts of the narrowing comb can now be moved in unison to right or left. When a split connection is to be produced the parts 11 and 12 are moved away from the part 4, as in Fig. 2, by inserting the intermediate member 31, and withdrawing the member 46, whilst the stop 53 is swung to the inoperative position. The part 4 may be shifted laterally for patterning, by the stop 17. For the production of the toe portion, the part 4 is swung into inoperative position, the members 31, 32, are withdrawn and the members 45, 46 are in front of the rod 38. The two parts 11, 12, are then separated by a space corresponding to a few needles only this space being necessary for the narrowing operation.

Abstract: 294,526. Newport Co., (Assignees of Gubelmann, I., and Henke, C. E.). July 25, 1927, [Convention date]. Grant of Patent opposed. Resits.-Wood or gum rosin is purified and decolourized by treating a solution of it in a solvent relatively immiscible with resorcinol, with resorcinol, and then separating the resorcinol containing the impurities and colouring matter from the purified rosin solution. The solvent is preferably a volatile hydrocarbon such as petroleum naphtha, gasoline, turpentine, &c., the treatment with resorcinol being effected at an elevated temperature and separation effected by cooling and decantation. The resorcinol may be recovered for reuse by extracting both the rosin solution and the solid mass of resorcinol and impurities with water, and then evaporating the resultant water solution of resorcinol. The process is particularly applicable to a commercial solution containing rosin, pine oil, and other terpenes, which is usually obtained by extracting resinous woods with petroleum naphtha. Specification 275,862 is referred to.
