Abstract: ABSTRACT          Artificial insemination Apparatus, especially for Hens Mr.  Robert CASSOU Mr.  Maurice CASSOU Mr.  Bertrand CASSOU            The invention relates to apparatus of the kind comprising a holder which has a cylindrical passage (3) with which are associated a member (4) for ejecting the semen and also a reservoir tube (I4) containing semen which is fixed by a grip (I6) relative to this passage, so as to be disposed at the front of the holder.          The problem is to reduce the cost of such apparatus.          In accordance with the invention, the reservoir tube (I4) is fitted directly onto the holder (I) by fitting the rear end (I4a) of the tube onto a snout (2a) solid with the holder (I) and surrounding the passage (3), the reservoir tube presenting a convergent front end for self-supporting insertion into the animal.          The invention is principally of use in insemination of hens.                                Fig I

Abstract: HYDRAULICALLY ACTUATED WINCH ASSEMBLY   ABSTRACT OF THE DISCLOSURE A hydraulically actuated winch assembly having a dual planetary gear system for driving a common ring gear from a power input shaft,  Power from the shaft is divided through the two planetary gear systems for driving the common ring gear which is attached to the load member, such as a winch drum.  A brake assembly can be assembled as a unit and then inserted into the winch assembly and is axially fixed in position by a retainer plate that is held on the housing of the winch assembly by means of a snap ring.  The brake assembly is axially inserted into the housing and against the snap ring and bolt means then are secured between the retainer plate and brake assembly so as to fix the assembly in position within the housing.          The brake assembly includes an axially extending piston rod forming a part of a hydraulic actuator which actuates the brake assembly and the power input shaft for the plane-tary gear system is piloted in the end of the piston rod.          The common ring gear which is driven by the planetary systems is axially secured to the housing by cap screws which in turn are held against inadvertent loosening by the winch drum which is assembled over the cap screws.

Abstract: IMPROVED CAPACITIVE TOUCH SWITCH ARRANGEMENT            ABSTRACT OF THE DISCLOSURE         A capacitive attenuator type touch switch cell arrangement employs a touch responsive pad or electrode and a receiver electrode of comparable surface area on opposing surfaces of a dielectric substrate for capacitive coupling there between, which capacitive coupling is alterable by the human touching of or proximate to the touch pad.  A scan signal is coupled from signal generating circuitry to the touch responsive pad by a separate transmitting capacitor.  Signal detection circuitry senses the signal coupled to the receiver electrode to detect attenuation of the coupled signal signifying the touching of the touch pad.  The use of a separate capacitor to provide the transmitting capacitance reduces the touch pad area requirement, thereby permitting closer spacing of touch switch cells for greater switch density on a control pad.

Abstract: IMPROVED FLEXIBLE STATOR SLOT CLOSURE ARRANGEMENT            ABSTRACT OF THE DISCLOSURE           A slot closure arrangement for closing the slot opening of slots in the stator of a dynamoelectric machine and for providing a restraining force against conductors in the slots  The slots have opposing notches on opposite sides of the slot adjacent the slot opening.  A flat rectangular spring member is placed in the slot opening with the opposite edges of the flat spring member each terminating in one of the opposing notches.  A pair of wedges with complementary tapered surfaces is inserted between the spring member and the surface of the conductor in the slot adjacent and facing the slot opening. The wedges are advanced one over the other to increase the overall thickness.  The surface of the wedge engaging the spring member has a thickness at the center greater than the thickness at the edges, and the center presses the spring member outwardly when the wedges are advanced, deforming the spring member which then provides a force through the wedges against the conductor in the slot.  The spring member not only provides the restraining spring force but it serves as a slot closure member.  Because there is no material covering the outer surface of the spring member (except for the extreme edge portions within the notches), nothing impedes heat dissipation from the spring member to the ventilating air.
