Title: Plastics dispenser body having injection and blow moulded parts.
Inventor: SAFFRON RONALD GEORGE
IPC: B29L22/00
Filed: 1989-09-15
Abstract: A method is described for producing a dispenser including a plastic body which defines two vertically spaced compartments (2, 3) connected by an orifice closable by a plug valve (6) which co-operates with a seating (5) set in the internal periphery of the orifice to provide a seal between the two compartments (2, 3). The body section (2) which defines the upper of the two compartments is of tubular construction and the body section (3) which defines the lower of the two compartments is capable of flexing movement towards and away from the mid section of the body in which the orifice between the two compartments (2, 3) is defined. The method includes the steps of producing by an injection moulding technique a semi-finished product comprising the upper and mid body sections and a parison dependent from the mid body section, and subsequently blow moulding the parison to produce the lower compartment of the dispenser.

Title: Suction cleaner for wet cleaning
Inventor: BAXTER JOHN
IPC: A47L9/06
Filed: 1990-02-03
Abstract: A suction cleaning nozzle has an elongate cleaning fluid delivery compartment (13) between forward and rearward suction compartments (11, 12), the cleaning fluid delivery compartment receiving an insert 21 having a series of grooves 29 in one surface to define feed passages for the cleaning fluid, and a sloping runway 24 along its top edge to promote the flow of cleaning fluid from an inlet 18 to the opposite ends of the nozzle.

Title: Digital filters
Inventor: LUTHRA AJAY K
IPC: H03H17/02
Filed: 1990-07-10
Abstract: The present invention provides a method of using long digital filters in the presence of quantisation/round-off errors by prescaling each filter coefficient C'O - C'C(N-1) by a scaling factor. The prescaled coefficients are used to weight at 14 input data samples. The resulting weighted data values are then divided at 16 by the appropriate scaling factor and combined to produce an output data sample, Yn. Each filter coefficient is multiplied by an appropriate scaling factor, then quantised and fed to a multiplier 14. Each input data sample may be separately processed and then combined in successive summers 17. The delay elements may be connected in series or in parallel with the input data path. The filter may be an FIR filter. <IMAGE>

Title: Cooling apparatus for grinding machines
Inventor: PESCHIK WERNER
IPC: B23Q11/10
Filed: 1992-09-04
Abstract: Apparatus for supplying coolant to the location of contact between a workpiece 9 and a grinding wheel 7 has one or more reciprocable and indexible carriers 16, 16a each of which removably or fixedly supports two or more different nozzles 17, 17a. This enables each carrier to maintain a selected nozzle in an optimum position for delivery of coolant to the location of contact. At the same time, the other nozzle or nozzles are sealed from a source of coolant so that the coolant is not wasted. The nozzles can be removed from their carrier or carriers individually or in groups of two or more. Alternatively, each carrier with all of the nozzles thereon can be replaced with a carrier mounting a different set of nozzles. Nozzles can be exchanged simultaneously with the grinding wheel, and the operation of the cooling apparatus can be automated, for example, in such a way that the stream or streams of coolant issuing from one or more selected nozzles follow a changing location of contact. <IMAGE>

Title: Axial securing mechanism
Inventor: BUSCH HANS-WALTER
IPC: A47C1/025
Filed: 1993-08-06
Abstract: An axial securing mechanism to fix, for example, a gear wheel 23 on a shaft 12 has the gear wheel 23 non-rotationally arranged on an offset portion 21 by means of entrainment gear-teeth 22 and secured axially by deforming a ring 26 into groove 25 by forcing it onto entrainment gear-teeth 22. To produce clearance-free axial securing which is not affected by the accuracy of the thickness of the gear wheel 23, the offset portion 21 is greater in length than the thickness of the gear wheel 23 and between the offset portion 21 and a journal, which is a smaller external diameter than the offset portion, is groove 25. The material of the ring 26 is deformed, by the teeth 22 which penetrates the ring 26, when the ring 26 is pressed onto the offset portion 21. The ring 26 is pressed onto the offset portion 21 until it abuts against the gear wheel 23. <IMAGE>
