Title: Bobbin donning
Inventor: SLAVIK WALTER
IPC: B65H67/04
Filed: 1986-09-05
Abstract: A yarn handling machine has a yarn winder with a cradle (14A, Fig. 3) for holding a bobbin tube/yarn package in contact with a friction drive roll (10). A bobbin donner comprises a bobbin gripper (30) pivotably mounted on a carrier (pivotable arm 32). The donner transfers the bobbin (22) to the cradle (at 18), but keeps a grip on the bobbin, while pivoting on the carrier, as the cradle carries the bobbin to the drive roll. One cradle arm is there opened to allow clamping of yarn between a bobbin end and the opened arm, the gripper maintaining the bobbin against the roll. The gripper comprises rollers (74, 78, 88, Fig. 4) which grip the bobbin and which are "skew" to the bobbin axis so that with drive roll rotation the rollers urge the bobbin axially against the un-opened cradle arm. <IMAGE>

Title: Domestic hot water systems
Inventor: HANSON-GRAVILLE GEORGE
IPC: F24D3/08
Filed: 1986-10-13
Abstract: A domestic hot water system comprises a satellite cylinder 4 for water to be heated rapidly. The main cylinder 1 is heated indirectly by a coil having an inlet 2 and an outlet 3 which communicates with the return feed D to the boiler or other heating source. A hot water draw-off outlet A from the cylinder 1 is connected to the satellite cylinder 4 and this includes an outlet B which then serves as the water supply draw-off. Within the satellite tank 4 is located a finned heat exchange unit with an inlet C for connection with the hot water supply of the boiler and an outlet which connects with the input side of a changeover valve E. The valve E may be set by means of a control 5 to direct the heating water supply output from the satellite tank 4 either through pipe F to the inlet 2 of the coil in the cylinder or through pipe 6 to directly communicate with the outlet D thereby by-passing the coil to heat water in tank 4 rapidly.   The heat exchanger in tank 4 may comprise fins of convoluted wire and an internal wire brush-like element to assist heat transfer. <IMAGE>

Title: Band saw for dividing up animal carcases
Inventor: SYRE MANFRED
IPC: B23D55/10
Filed: 1988-02-12
Abstract: A band saw (10) for dividing up animal carcases has two rollers (13 and 14) on which a saw band (15) is guided. The roller (14) can be displaced to change the spacing of its axis from the axis of the other roller (13). For this purpose, the roller (14) is guided for longitudinal movement in a slide and the slide can be displaced by a tensioning device (17) which is limited by its design, in terms of its total travel, so as to permit only a structurally predetermined maximum tension of the saw belt (15) to be obtained regardless of the adjustment skills of the operator. Risk of extensive high tension can therefore be avoided. The tensioning device (17) comprises a tensioning member (22) moved to its tensioning position by movement of a cover (12). In Fig 4 (not shown), the tensioning member (22a) comprises a cam plate. Setting guides (16) for the interlaced guidance of a cutting pass (15a) of the saw band, each comprise two guide parts (18, 19 Fig 3) displaceable relative to one another upon opening and closing of a cover (12). <IMAGE>

Title: Cache memory
Inventor: CRANE DAVID PAUL
IPC: G06F12/12
Filed: 1988-10-28
Abstract: A cache memory has a RAM 23 for holding flags pointing to the most recently used data item in each of a plurality of sets. When a data item is loaded into the cache, the item to be replaced is selected by excluding the most recently used item in the set in question, and selecting one of the remaining items on a non-usage basis, for example a random basis. This not-most-recently-used (NMRU) replacement algorithm requires fewer storage bits than a conventional least-recently- used (LRU) replacement algorithm, while giving better performance than a purely non-usage based replacement algorithm. <IMAGE>
