Title: Device for storing and dispensing webs of material
Inventor: OFFORD JOHN
IPC: B41J11/58
Filed: 1982-07-02
Abstract: A device for storing and dispensing webs of material is in the form of a trolley (10) having a plurality of trays (16) for receiving individual webs of material, and having a bank (18) of dispensers arranged for dispensing the webs of material from a single central location. Each dispenser is associated with a respective tray (16) and is operable to grip the associated web for retaining it in readiness for use and to permit or cause withdrawal of the associated web from the respective tray for use. Each dispenser may be in the form of a clamp consisting of a fixed plate (38) and a movable blade (42) secured to a rod (44) which is pivotally supported. The blade is movable between two stable positions, in contact and away from the plate 38, and is held in these positions by spring (50) or by weights or magnets. Rod (44) is manually rotated by an operating knob at one end. Alternatively, each dispenser may be a pair of rollers motor driven and/or biased together resiliently or magnetically or by being supported in angled slots. An additional removable receptacle (20) may be disposed above the bank of dispensers for receiving used webs. Each tray (16) may be partitioned and carry two webs, each dispenser then dispensing two webs at a time. <IMAGE>

Title: Retaining pin assembly for earthworking tool
Inventor: RADIGAN MICHAEL
IPC: E02F9/28
Filed: 1981-03-16
Abstract: A retaining pin assembly (16) for securing a replaceable earthworking tool (14) to a support member (12) includes a spring type pin (36) and a coacting sleeve (40). The pin assemby (16) is insertable through generally aligned openings (30, 22) in the tool (14) and support member (12) and functions to lock the tool (14) to the support member (12) and to force an end portion (28) of the tool (14) into contacting relationship with shoulders (18, 20) of the support member (12). Earthworking apparatus, such as impact rockbreakers and rippers, generally include a replaceable tool mounted on a shank or support member. Unless the tool is forceably held in contacting relationship with the support member, the retaining pin, tool, and support member are subject to damage. The retaining pin assembly (16) of the present invention secures the tool (14) and support member (12) in contacting relationship and maintains a continuous locking force between the tool (14) and the supporting member (12).

Title: Electro-magnetic saturation and possible re-setting of Wiegand effect sensors
Inventor: VESTER KLAUS
IPC: H03K17/97
Filed: 1983-08-30
Abstract: A Wiegand sensor 4, which is triggered by a rotating permanent magnet 2, is saturated electromagnetically by means of a circuit 8 triggered by the Wiegand pulses, which then supplies for a short period an electrical current to the sensor induction winding 7 of the Wiegand sensor 4 in order to build up a saturating magnetic field. This is stated to be preferable to the conventional use of a permanent magnet to saturate the sensor. The re-setting permanent magnet 5 can also be replaced by a further winding which is energised between the periods when electromagnetic saturation is taking place. <IMAGE>

The ring (37) is provided with inwardly extending flanges (43, 44) which overlap the rims (45, 49) and urge them against a circumferential bead (38) of the rolling diaphragm (7). The distances (a, b) between the plane of the peripheral surfaces (41, 42) of the rims and the outer surfaces (47, 48) of the casing shells (22, 23) are from one to one and a half times the thickness (c) of the casing shells (22, 23), and results in the effective diameter (f) being favourable compared to the installation dimension (g). The rims (45,49) may extend at angles ( alpha ,  beta ) which are preferably 60 DEG . In a second embodiment, Fig. 3 not shown, flange 43 is replaced by indentation (50) which engage rim (45). <IMAGE>

Title: Metal-working compositions
Inventor: KUWAMOTO HIROSHI
IPC: C10M141/00
Filed: 1984-05-31
Abstract: A metal-working oil composition containing:-   (A) one or more lube-oil components which are oils and fats, mineral oils or fatty acid esters; and (B) one or more polyetherpolyol dispersants which are made by adding alkylene oxides to polyalkylene- imines or -polyamines, alkyl- or alkylaryl-amines, or carboxylic acid amides, or their derivatives, e.g. polyetherpolyol derivatives having molecular weights of 300 to 600,000 and obtained by adding alkylene oxides to polyalkyleneimines.

Title: Braking pressure generator
Inventor: BELART JUAN
IPC: B60T11/20
Filed: 1986-05-16
Abstract: In a vacuum brake booster and master cylinder (34) assembly a push rod (14) coupled to a movable wall (2) of the brake booster displaces a first piston (33) in a stepped bore (29) of a housing (34,34a), the said first piston (33), via a pressure fluid column enclosed in an annular chamber (37) displaces a second smaller diameter piston (31) faster into a pressure chamber (40) which is in communication with a wheel brake. On vacuum failure, a compression spring (48) displaces a flexible diaphragm (44) disposed in an inner chamber of the first piston (33) to, in turn, via plungers (49,49'), opens valves (50,51,50',51'), via which the pressure fluid in the annular chamber (37) can flow back into a hydraulic reservoir. The first piston (33), via an extension (38) with a shoulder (41) engages the second piston (31) causing an equally rapid displacement of the second piston (31). As the effective hydraulic cross-sectional surfaces (F-f and F'-f, respectively) of the two pistons (33,31) are of different sizes, normally - with the brake force booster intact - the second piston (31) is displaced faster than the first one. <IMAGE>
