Title: Flared grinding wheel
IPC: B24D7/02
Filed: 1980-09-09
Abstract: A flared grinding or abrading wheel in which the leading end of the periphery of the wheel body (1) is provided with an annular recess (13) receiving an abrasive insert ring (3), has the rear end part (130) of the recess (13) formed such that it is of a diameter about the wheel axis not more than the minimum internal diameter of the insert ring (3). This enables the ring (3) to be co-axially introduced over the periphery (12) of a pre-formed wheel body (1) at the rear end of the latter and then axially slid into the recess (13) for adhesive securing or bonding therein, e.g. by appropriate pre- treatment of the recess (13) and internal periphery (30,31) of the ring (3). The rear end part (130) of the recess (13) and the co-operating internal peripheral part (30) of the ring (3) are shown parallel with the axis of the wheel but other formation may be employed as described. <IMAGE>

Title: Doors
IPC: E05D15/10
Filed: 1980-12-16
Abstract: An improved fire door suitable for application within limited spaces includes a closure member 10 for an opening O suspended by mounting members 20, 30 having runners 21, 22 located within channels 12', 13' to guide the runners 21, 22 and hence the closure member 10, to slide in a fixed plane.

Title: Pipe connector
IPC: F16B7/04
Filed: 1981-02-27
Abstract: A pipe connector for connection to a pipe having a plain end comprises a body (10) having a profile matching that of the pipe, and a pair of jaws (12) extending outwardly for insertion within the end of the pipe. The jaws are formed with oppositely directed clamping surfaces (24, 26) for engaging the inner wall surface of the pipe end. One of the jaws (14) is fixed and integral with the body (10). The other jaw (16) is pivotally mounted on the fixed jaw (14) and is extended inwardly of the body (10) where it is threadedly engaged by a screw (38) which connects the pivoted jaw with the body so that by rotating the screw (38) in the appropriate direction the pivoted jaw (16) pivots away from or towards the fixed jaw (14) to clamp or unclamp the jaws from the pipe. The screw (38) thus provides a positive clamping force which greatly assists the dismantling of the connector from a pipe end when desired. The screw (38) also retains the pivoted jaw (14) in place and there are no loose parts to become lost.

Title: Time metering devices
IPC: G07F17/24
Filed: 1980-09-10
Abstract: An electronic parking meter (10/50) comprising a display device (20/56), a timer (24, 31/62, 67, 64) and a control means (28/62) operable to set the timing device (24, 31/62, 67/64) in operation for a purchased parking time in response to insertion of coins into the meter. The display device (20/56) is arranged to give an initial display of purchased time, but for this display to be inhibited shortly afterwards so that a user of a previously vacant parking lot controlled by the meter cannot determine from the meter whether there is any unexpired parking time left for that lot by a preceding user. In one form, the meter is controlled by a central processing unit (62) and is arranged for storage in a memory (64) of user supplied data such as vehicle registration number and parking lot identification, as well as of purchased time. For controlling several parking lots by the meter, the meter is provided with a selector (22/52) enabling the user to select a desired parking lot.

Abstract: A double universal joint is provided with improved centering means. One end yoke of the joint has a circular ridge or tooth 146 and a central tooth 148 facing the other end yoke with the center line of the teeth being coaxial with the axis of rotation of the one yoke. The other end yoke has circular ridges or teeth 152, 154 and a central recess 158 facing the one end yoke with the center line of those teeth and recess being coaxial with the axis of rotation of that yoke. The teeth are positioned so that one tooth extends between two teeth of the other yoke for any position of the end yokes and the drive and driven members or shafts to which they are attached. The sets of teeth are in patterns of spherical segments so that any longitudinal cross section taken centrally through the teeth has the same general appearance as a section gear through a segment. In a preferred form, the tooth profile or shape in transverse section is such that intermediate portions are thicker than both inner and outer end portions. The center tooth is also thicker in transverse cross section than the other teeth and the central recess is wider in transverse cross section than grooves between the teeth. <IMAGE>

Title: Method and Apparatus for Feeding Wafer Pieces into Casting Moulds
IPC: A23G3/20
Filed: 1981-10-27
Abstract: To manufacture chocolate slabs filled with wafers, wafer pieces (2) are laid into depressions (7) in chocolate- slab casting moulds (5), these depressions being lined with chocolate. The wafer pieces (2), lying against one another both laterally and in a longitudinal direction, are first moved counter to the direction of transport of the casting moulds (5), then guided apart from one another laterally to a lateral spacing corresponding to the lateral distance between the depressions and in a longitudinal direction to a longitudinal spacing corresponding to the longitudinal distance between successive depressions. Finally, the direction of movement of the wafer pieces is reversed and the pieces are laid synchronously with the movement of the casting moulds into the depressions (7). The apparatus provides, above the conveying arrangement for the casting moulds (5), a spreader device (8) for the wafer pieces conveyed, lying against one another, counter to the direction of movement of the casting moulds, and, connected downstream of the spreader device against the direction of movement of the casting moulds, a transfer device including a drum 21 with wafer-receiving mandrels 22 which lays the wafer pieces in the casting moulds. <IMAGE>

Inventor: JOHANSSON HAKAN
IPC: B23Q9/02
Filed: 1982-11-05
Abstract: Method and apparatus for machining, especially boring, of machine parts (22), for example for forestry machines, power shovels etc. When certain types of damages, for example on hinges, shaft journals etc. occur on, for example, forestry machines, power shovels etc., boring operation is required. Heretofore this operation could not be carried out in situ. It was, thus, necessary to dismantle the damaged machine part and transport it to workshop. The present invention is characterized in that a guide member (1) is fixed temporarly in correct machining position relative to the machine part (22). Thereafter a machining tool (31) is moved along the guide member while simultaneously the tool (31) for carrying out the machining proper of the machine part (22) is rotated. When the machining is completed, the guide member (1) is removed from its fixed position.
