Title: Oscillographic ferrometer with single-layer ellipsoidal solenoid - has rectangular solenoid turns such that homogenous field zone is large
IPC: G01R33/14
Filed: 1975-01-07
Abstract: The oscillographic ferrometer has a magnetizing means including a step-down transformer and a single-layer ellipsoidal solenoid connected to a single-turn secondary winding of the step-down transformer and having a constant turns density along the generatrix.

Title: Pneumatic lock for mould with cam actuated catch - for automatically opening and closing moulds on a moulding line
Inventor: FAVIER ROGER
IPC: B22D33/04
Filed: 1975-03-19
Abstract: Look for mould comprises a pneumatic bolt mounted on two supports by means of a shaft and two crossbars, with an air intake for actuating the bolt to drive two connecting rods which are mounted on a shaft by means of a clamp. The connecting rods cause rotation of two cams in two bronze collars which are attached to two catches. A crossbar and a lug maintain the distance between the axes of the two catches. Rotation of the cam causes the catch to close the mould cover; before final closure, a spring allows the catch to pi of forwards onto the mould cover. To open the mould, air enters at another point, and the bolt actuates the catch in the reverse direction by means of the connecting rods which abut against another crossbar causing the catch to pivot backwards.

Title: Tool for drilling holes and cutting grooves - has elongate channel member in channel in abrasive tip with end face recess
Inventor: FRENKEL S T
IPC: B28D1/14
Filed: 1975-04-23
Abstract: The tool is particularly for hard, brittle materials such as glass and ceramic and has a shank (1) which receives a cutting tip (2) of material containing abrasive. In a longitudinal slot in the tip is an elongate bar of material whose abrasive resistance is lower than and whose binding strength is higher than those of the cutting tip material. The surface profile of the bar is identical in cross-section to that of the slot so that the surfaces are closely mated. A recess (6) in the end face (5) of the cutting tip is arranged so that abrasive particles on the end face are located at and beyond a distance (a) from the axis (7) of rotation of the tool, so that a core pin formed in the hole being drilled thrusts against the curvilinear bottom (8) of the recess (6). The core pin abrades or breaks and abrades the bottom (8). The channel shape of the bar facilitates abrasion of the bar and allows a good supply of cutting coolant and removal of sludge from the cutting area.

Title: Garbage-thickened sludge conversion to compost - in treatment chamber with air preheated by hot waste gases
IPC: C05F17/02
Filed: 1975-06-10
Abstract: Garbage and/or thickened sludge are converted to compost in a treatment chamber where an air stream encourages the aerobic conversion.

Title: Central air handling plant for ventilation system - has heat pump with evaporator operated at frost forming temp. during peak heating periods
Inventor: DUPUY BRUNO
IPC: F24D11/02
Filed: 1976-06-17
Abstract: The air treatment plant has a passage (2, F1) for fresh air supply to a room and a passage (5, F2) for air extracted from the room.

Title: Underground telephone cable - without electrostatic screen or exterior sheath, has low out-of-balance capacity with respect to earth
IPC: H01B7/36
Filed: 1976-07-29
Abstract: The telephone cable is made up of a twisted pair of wires, one of which has a longitudinal reference rib on it whilst the other is completely circular. The insulation of each conductor of the pair is formed by a layer of polyolefin which gives the transmission characteristics of the cable. A second thin layer of semiconducting material forms an external skin. The longitudinal reference rib is formed in this second layer. Both the layers can be extruded simultaneously or in two stages. The cable arrangement permits maintenance of stable capacitance and low out-of-balance capacity with respect to earth. It has propagation, insulation and dielectrical characteristics identical to those of classical telephone cables whatever the external surrounding medium is.

Title: Self-tapping screw for use with plastics - uses maximum of three full threads to reduce screw driving torque
IPC: F16B25/00
Filed: 1976-10-01
Abstract: The self-tapping screw is for use with plastics, especially that type of plastic where the thread is formed by deforming the material rather than cutting a clean thread. The screw has a shank (2) in which the threaded portion is divided into two sections. The section near the pointed tip (5) consists of at least three full threads of full diameter (d1). The rest of the threaded section has threads of diameter (d4) which is between 0.92 and 0.96 of the diameter (d1). The leading threads (6) cut the thread in the hole in the plastic and the tendency of the plastic to resume its original shape does not produce a high torque on the remaining thread of reduced diameter.
