Title: Forming tulip ends on thermoplastic pipe - using a simple two part mandrel to facilitate disengagement without distortion
IPC: B29C57/02
Filed: 1972-09-13
Abstract: Tulip ends are formed on the end of thermoplastic tubing by preheating the tube end and forcing it over a mandrel made in two parts, one part being sized to enter the original bore of the tube and diverging to dilate the tube mouth as it is forced over the mandrel, the second part being of the constant dia. required as the bore of fully shaped pipe entry. the two parts of the mandrel are separable so that the nose part can be used to push the shaped tube off the second stage of the mandrel before being disengaged itself. Pref. a thermostated sleeve type heater is used to ensure uniform preheating of the tube end. The leading part of the mandrel supports the tupil shape while disengaging the cylindrical contact area between the mouth and the mandrel. Subsequent disengagement of the leading part involves small surface contact areas as soon as initial displacement is achieved.

Patent FR-2242807-A1 (FR)
IPC: B62D33/06
Filed: 1974-08-22
Abstract: Clock pulses are multiplied by a ratio less than 1 of which the numerator is controlled by a reversible counter. The multiplier output pulses initiate new countdown cycles of a second counter beginning with the clock pulse following the onset of an input frequency pulse and ending with the clock pulse following the onset of the next input frequency pulse. The state of the count at the end of the cycle determines whether the reversible counter will be left unchanged, advanced, or counted back and hence, whether the multiplier output frequency will be left unchanged, increased or reduced. The initial countdown value of the second counter is provided by a long term store which determines the frequency multiplication ratio. The circuit is usable to multiply a variable input frequency in a vehicle brake anti-lock system.

Title: Tractor and trailer for solid refuse - has trailer able to tip and with removable dividing walls
IPC: B65F3/00

Title: Encapsulating an injection machine nozzle heating strip - to prevent any contact between hot plastics and conductors
IPC: B29C45/74
Filed: 1974-10-17
Abstract: A strip heating device for the nozzle of a plastics injecting machine comprises a resistance heating element and supply cable. The entire unit is encapsulated to protect the supply cable and heating resistors from any contact with the hot plastics. The heating strip is pref. a hermetically sealed sleeve contg. the resistors, having an external cap into which the supply cable is positioned; the latter part of the supply cable being contained in a hermetically sealed sheath. The strip, cap and sheath are connected together, e.g., by welding or soldering to form a closed unit. The length of the protective sleeve around the cable is sufficient (15 cm.) to provent the cable conductors from the plastics. Matls. for all the sheath elements are metals, and the cable sheath is esp. copper. Heat-resistant insulating matl. esp. a mineral insulator, may be contained round the cable inside the sheath. By completely excluding any hot plastics matl., the prodn. of carbonised plastics over a period of time in the region of the cable attachments etc., is prevented, and thus short-circuits are avoided and the life of the entire unit is prolonged.

Title: Fire-resistant protective coatings for building components - contg. plastic particles dispersed in hydraulic binder which form cavities when heated
IPC: C04B28/02
Filed: 1974-11-15
Abstract: Thermal protective coating for metal and non-metal building components, e.g. panels, consists of (1) a conventional hydraulic binder contg., in dispersed form, and (2) particles of a plastic material, which may be expanded or non-expanded, and are capable, at a predefined temp., of creating a space in the coating mass. Compsn. provides a uniform coating giving good protection to coated components under normal conditions. When subjected to heat or flames the coating develops a cellular structure at the predefined temp., e.g. 90-160 degrees C. This gives excellent protection against the propagation of the fire.

Title: Special box for ritual slaughtering of cattle - with articulated floor and walls for immobilising animal
Inventor: CHARLES HENRI
IPC: A22B3/12
Filed: 1975-02-10
Abstract: Special box for the ritual (kosher) slaughtering of cattle, comprises a chassis, an entry door and a floor this is articulated on one of its edges to the chassis by means of hinges and to a lateral wall by articulation hinges. Ball-bearing rollers slide in corresponding roller tracks. The assembly formed by the floor and the wall can be lifted by the jack to form a kind of funnel with the opposite wall. The animal standing on the floor is throw off balance as the floor is tilted and its four feet are clamped between the lower edge of wall and the edge of the floor, so that the animal is completely immobilised. The animal is then lifted upside down, by a sling attached to one leg, on to the area outside the box, the wall being lifted to allow the animal to pass underneath; it is bled in this position and then evacuated by the overhead handling system of the abattoir. The floor and walls of the box are put back in their original position, ready to receive another animal. The special box allows some 25-35 cattle to be ritually killed in an hour; evacuation of the carcass by the normal handling rails is simple.

Title: Telephone multifrequency switching signals detection - uses analysis circuits with filter outputs counted during enabling period
Inventor: COPPENS CHRISTIAN
IPC: H04Q1/457
Filed: 1975-05-13
Abstract: Multifrequency signals employed in telephonic telecommunications switching are detected using two analysis circuits for all the components of a multifrequency code of the 2 from n type. This method overcomes difficulties experienced with tuned filters in parallel. Two analysis circuits are connected in parallel to a telephonic line (L). One circuit contains a high pass filter (PH) while the other contains a low pass filter (PB) both comprising operational amplifier circuits with RC networks. The filter outputs are amplified (A1, A2) to obtain square waves for application to counters (CR1, CR2) which count during a time period determined from an enabling input (K). The counter outputs (S1, S2) therefore depend on the frequency inputs.
Patent FR-2275817-A1 (FR)
Title: Control system with controller and regulating drive - has at least two constant regulating speeds
IPC: G05B11/28
Filed: 1975-06-17
Abstract: The controller has connected to its output a comparator element. When adjustable limit values of the controller output signal are exceeded, a control mechanism is actuated to reverse the regulating speed. There can be a discontinuous controller with modulation of the pulse length of its output signal and the adjustable limit values in the comparator element can be proportional to time. There can be a limit-value indicator switched parallel to the controller and comparator element and comparing the deviation with adjustable limit values and operating the control mechanism. A series of responses is simply built-up enabling quick regulating possibilities to be realised.

Title: Car door operated switch with time delay - has pushbutton and bellows to control operation of contacts
IPC: H01H43/28
Filed: 1975-07-16
Abstract: A door operated switch is used to switch on or of inside lights of a road vehicle. However, with these switches drivers often leave the door slightly opened while ignition keys or other keys are used before closing the doors completely. A time delay switch can be used to overcome the dangerous practice of leaving doors open. The time delay switch, has push-rod (5) which can slide in a case(2). The push-rod (5) is part of a box (6) which can slide on two slides (7). Within the box (6), there is a bellows (11) and within the bellows (11) there is a moving contact disct (12), springs (20, 23) and a flat (25). When the door of the vehicle is open, the disc (12) makes contact with a spring (24) to close the circuit with a lamp (13). When the door is closed, the push-rod (5) is pressed, the box (6) compresses a spring (19) but the bellows (11) only slowly moves to its original position and the opening between the disc (12) and the spring (23) is delayed according to the amount of air passing through the flap (25).
