Title: Vehicles
IPC: B62D49/08
Filed: 1973-07-23
Abstract: 1429693 Counterweights CATERPILLAR TRACTOR CO 23 July 1973 [21 Aug 1972] 35056/73 Heading B8B [Also in Divisions E1- E2] The frame of a vehicle, e.g. an excavator or a loading machine, is provided with an opening, defined by structure members 20, 22, 24, 28, 30, into which a counterweight 35 can be entered in a substantially horizontal direction to rest on and be secured to support means 28, 30 integral with the frame. Movement of the counterweight into the opening is limited by stop members 36, 38. A second counterweight 48 may be fitted to the rear of the frame to retain the first counterweight 35 in the frame. Members 42, 44 are secured to the frame to act upon the top portion of the first counterweight 35 to prevent it from falling due to its weight out of the opening whilst, during fitting into or removal from the opening, it is only partially supported by the support means 36, 38. The second counterweight is formed with a towing hitch 56. A lifting eye may be fitted into a tapped hole 46 to allow of lifting up of the counterweight and of its partial entry into the opening until it is retained in the opening by the members 42, 44, after which the eye is removed and the counterweight fully entered into the opening.

Title: Device for differential braking of front and rear wheels in a motor vehicle hydraulic braking system
IPC: B60T11/34
Filed: 1958-11-03
Abstract: 837,388. Fluid-pressure brakes. FIAT S.p.A., and BALDWIN, P. S. Nov. 3, 1958 [Nov. 14, 1957], No. 35241/58. Class 103 (1). A device 8 for insertion in the conduit of a vehicle hydraulic brake system, which leads to the rear wheel brake cylinders, has the effect of reducing the pressure transmitted to the rear wheel brake cylinders in relation to that transmitted to the front wheel brake cylinders. The reduction takes place as a result of the action of a stepped piston 18. Pressure fluid supplied to connecting pipe 13 passes straight through to connection. 14, past valve 34, and along bore 32 and through radial passages between ribs 30 and radial openings 48, until the pressure differential across the stepped piston is sufficient to cause it to move against spring 37 and close valve 34 upon its seat. The condition is represented by the point marked I on the graph of Fig. 4. Thereafter the pressure rise for the rear wheel brake cylinders is represented by the line III, as compared with that for the front wheel cylinders represented by the line II. Reduction of braking effect on the front wheel cylinders is advantageous for reducing wheel lock due to the weight distribution resulting from forwards movement of the C. of G. during retardation.

Title: Measuring device
IPC: G01R19/10
Filed: 1959-10-23
Abstract: 908,355. Automatic voltage control systems. MASCHINENFABRIK OERLIKON. Oct. 23, 1959 [Dec. 23, 1958], No. 36046/59. Class 38 (4). In an automatic voltage regulation system in which the excitation of an alternator is controlled in response to the output of an A.C. voltage error measuring circuit across the alternator output and of the kind disclosed in Specification 901,785, the excessive field excitation which would be called for by a large drop in alternator speed is prevented by an override circuit. The measuring circuit consists basically of a circuit (not shown) which is responsive to changes in frequency and an opposing circuit 14, 15 which is responsive to changes in both frequency and amplitude. There is additionally provided a transformer 26 and rectifier 28, the output of which is in parallel with that of rectifier 14. Under normal conditions the output of rectifier 14 exceeds that of rectifier 28, but if the frequency falls below a predetermined value, the output of rectifier 14 will fall below that of rectifier 28 and rectifier 28 takes over. The alternator output is thus allowed to fall with falling frequency. In a three-phase embodiment, Fig. 4 (not shown), the output current of a three-phase rectifier fed from two single-phase transformers provides the override.

Abstract: 358,787. Centrifugal compressers. GUTEHOFFNUNGSHœTTE OBERHAUSEN AKT.-GES., Oberhausen, Rhineland, Germany. Nov. 29, 1930, No. 36058. Convention date, Nov. 29, 1929. [Class 110 (i).] To prevent surging in a centrifugal compresser, the latter is divided into two separate compressers a, b, of different nominal deliveries, an uninterrupted delivery range from above the surging limit of the small compresser to the maximum load being obtained by operating first with the small compresser a alone, then with the large compresser b alone, and finally with both together. The two compressers are fitted with non-return valves g in their delivery branches f and are put into and out of operation by flap-valves h arranged in the suction branches c. The valves h are actuated through linkwork by the cylinders i which themselves are operated, either automatically or by hand, by the regulating device k. The consumption of power, when either compresser is running with its suction branch closed, is reduced to a minimum by the provision of pipes l leading from the delivery branches to the cylinders i and adapted to be opened to atmosphere when the valves h are in closed position.

An apparatus suitable for producing a medical spray from a liquid or powder fed through a tube 18 comprises a receptacle 10 having a single central aperture 14 in its bottom wall 12 and a conduit 16 which supplies compressed air to the aperture and atomizes the spray material in the receptacle. The spray material is fed to the receptacle through adjustable supply means 18 whereby a thin film or layer is maintained on the bottom wall. The atomized material leaves via the open upper end of the receptacle. The bottom wall of the receptacle may be variously shaped, Figs. 2-4 (not shown). In the embodiment of Fig. 5 (not shown) an air chamber (28) is provided below the bottom wall of the receptacle, which wall is formed as a membrane with a plurality of apertures so that it vibrates at a high frequency under the air pressure. A slotted screen (34) assists the atomization, together with an adjustable baffle (38). In a further embodiment, Fig. 7 (not shown) variable air pressure is supplied to a liquid reservoir (50) causing the liquid to be fed to an apertured receptacle (20) via a pipe (51).

Abstract: 900,035. Screwdrivers. DUNLOP RUBBER CO. Ltd. Oct. 20, 1958 [Nov. 28, 1957], No. 37064/57. Class 61. A tool for fitting and removing the valve core of a pneumatic tyre or other inflatable article comprises a key part 2 for insertion into the valve barrel to engage the core, and a clutch part which comprises a cylindrical member 6 axially slidable and rotatable within a tubular handle 1 and having a pair of semi-circular part-helical teeth 9 at one end, each terminating in an abrupt longitudinal edge dropping to the commencement of the other tooth, and a driving part which comprises a transverse bar 5 secured across the tubular handle 1, the clutch part 6 being urged by a compression spring 10 towards the bar 5 and connected to the key part 2 which projects axially from the handle 1, the slope of the teeth 9 and the strength of the spring 10 being such that on rotating the handle 1 to turn the key in the inserting direction the bar 5 will ride on the helical teeth 9, but if the torque transmitted exceeds the predetermined value it will ride over them, depressing the clutch part 6 against the spring 10; and on rotating the handle 1 in the other direction the bar 5 will engage the longitudinal edges of the teeth 9 so as to transmit a greater torque without depressing the clutch part 6. The lower end of the spring 10 abuts against a plug 11 secured to the handle 1. The maximum torque is set by inserting a predetermined number of washers 13 between the spring 10 and plug 11. In a modification shown in Fig. 4, a key part 20 is rotatably anchored in the end of a tubular handle 21 by means of a flange 22. The stem 23 of the key part 20 is formed with a series of radially disposed ratchet teeth 25 which engage complementary teeth on a driving part 26. The part 26 is slidably but non-rotatably keyed with a handle 21 by a peg 27 engaging in a slot 28 in the handle. A spring 38 urges the driving part 26 into engagement with the teeth 23. The torque will be limited in the " insertion " direction by the teeth riding over each other against the action of the spring 38. A greater torque can be given in the " removal " direction since the torque is transmitted through the abutting longitudinal faces of the teeth.
