Title: A method of and an apparatus for severing the end thread left at the welt of stockings knitted on circular hosiery knitting machines
IPC: D05B23/00
Filed: 1981-09-16
Abstract: A knitted stocking 1 is drawn on to an axially-reciprocable, hollow, cylindrical support 3 having an orifice 5, in such a manner that the stocking welt 4 with the end thread 7 at its edge is flush with the orifice 5. The support 3 is movable from a reception position I to an operating position II in which it is axially aligned with a thread cutting device 6 comprising a housing 15 which has suction air connections 14 and which accommodates a rotatably mounted, spring-loaded cutting blade carrier beam 10 provided with two cutting blades 11. The beam 10 cooperates with a counter- cutting disc 8 which is angularly adjustable and which has a plurality of bores 9, forming counter-cutting edges on the inner surface of the disc 8, arranged in spaced relationship on a circle. In the position II the support 3 with the stocking 1 is moved up to the disc 8 and the end thread 7 is sucked into the housing 15 through one of the bores 9. The carrier beam 10 is then rotated and the end thread 7 is severed first time, whereupon the support 3 is moved away from the disc 8 and the latter angularly adjusted to such a position that when the support 3 is again brought up to the disc 8 and the end thread 7 sucked in again, a second cutting operation can take place to sever the end thread 7 to its final predetermined length. <IMAGE>

Title: Liquid metering apparatus
IPC: G01F15/075
Filed: 1981-09-29
Abstract: For enhancing the accuracy in the volumetric metering of beer, a flow meter (10) which is provided in the dispense line emits a pulse each time a predetermined volume of beer passes therethrough. After dispensing, for example, a half pint of beer the number of pulses received by an intermediate store (12) are compared by a digital comparator (14) with a corresponding number of pulses in a permanent store (16) corresponding to an exact half pint measure. If the registered pulses from the store (12) are within a range of 10% less or more than the number of pulses in the store (16) a computer (18) varies the number of registered pulses to equal the number of nominal pulses and the varied number of pulses is then entered into a totalisator (20). By means of the rounding up or down feature, the inherent inaccuracy in the flow meter becomes of little significance in terms of overall accuracy. <IMAGE>

Title: Vehicle train-tracking-routing apparatus and method
IPC: B61L25/02
Filed: 1981-10-08
Abstract: The movement route of a vehicle over a roadway track having a plurality of stations and control track switches is selected from a storage table of predetermined available routes in accordance with the known track plan and in relation to each station. The position of a vehicle with respect to the "signal-blocks" which are occupied or vacant is recorded continuously. When the vehicle arrives at each of the stations, the desired available route is established to the next station in relation to occupied track signal blocks, the known direction of train movement and track switches cleared to permit vehicle travel to the next station. The available route to the next station is cleared in time so the vehicle will not have to slow down or stop in front of a track switch. In addition the spacing of vehicle trains is regulated in relation to the plurality of stations.   <IMAGE>

Abstract: The invention concerns a ship's steering gear having two separate liquid pressure thruster units. The gear incorporates main and auxiliary pumping units (3 and 7 respectively) for supplying operating fluid to the thruster units (2A, 2B). The main pumping unit (3) has a liquid supply tank (4) containing a liquid level detecting device (6A, 6B) operable to de-activate the main pumping unit (3) and activate the auxiliary pumping unit (7) which has a liquid supply tank (11) containing liquid level detecting devices (10) operable at one level of liquid to connect the auxiliary pumping unit (7) to one thruster device (2A or 2B) and at a second lower liquid level to substitute the other thruster device (2B or 2A). In operation, drop of liquid level in the liquid supply tanks is used to signal the presence of a leak and to set in operation the auxiliary pumping unit and determine how it operates. <IMAGE>

Title: Interpretation of seismic records
Inventor: HERKENHOFF EARL F
IPC: G01V1/28
Filed: 1983-04-06
Abstract: In a method of interpreting seismic records, progressive changes in amplitude as a function of offset of common gathers can be more easily identified by emphasizing the degree of amplitude variation between "near" and "far" amplitude vs. time traces of each gather along a seismic line, and displaying the resulting near and far offset sections side-by-side. A significant - and progressive - change in P-wave reflection coefficient as a function of the angle of incidence (within sections) indicates valuable characteristics, say the fluid hydrocarbon-bearing potential and/or the lithology of the reflecting horizon.

Title: Process for the manufacture of products from reinforced polyester resins
Inventor: MCDOUGAL JOHN R
IPC: C08J5/24
Filed: 1983-11-08
Abstract: Process for the manufacture of glass fiber-reinforced polyester products. A ready-to-mold resin and reinforcement composite is prepared using an initiator which has been microencapsulated in order to prevent initiator-induced cross-linking of the resin reactants. The initiator is released during the molding of the composite by rupture of the microcapsules due to internal vapor pressure developed at a preselected molding temperature. The encapsulation of the initiator provides improved homogeneity and increased flowability of the composites during molding, and enables the provision of molded polyester products having higher degrees of cure and more defect-free finish surfaces.
