Title: Gripper arrangement for shoe upper forming machine - claws have light delivering and receiving detector devices
IPC: A43D23/02
Filed: 1975-04-10
Abstract: The arrangement has devices which first exert a relatively weak closing force on the claw components such that these come into the gripping position. On relative movement between the strips and the gripper, the pinching edge moves between the claws. Detector devices belong to the claws and on increase in the claw closing force they are so firmly moved together that the edge of the upper is firmly gripped when a given part of the edge is between the claws. The detector devices contain light delivery devices to deliver a light beam from one claw to the other and light determining devices to evaluate the light passage through the claws. The arrangement is such that the light beam is cut off in the case that the pinching edge is in a section exceeding a given value between the claws while the light passes between the claws when the pinching edge between the claws does not exceed a given value.

Title: Purifying brines for electrolysis - with all treatments done in a single, divided tank
Inventor: PYTLAK RICHARD
IPC: C01D3/16
Filed: 1975-04-22
Abstract: Brines for use in electrolytic mfr. of Cl2 and NaOH are continuously purified by first introducing into first reaction zone (A), by downwards flow at decreasing speed, a controllable vol. of (a) a mixt. of NaCl-satd. mother liquor and Na2SO4 at 50-80 degrees C, such that the SO42- concn. on entry to (A) is twice that when it leaves; and (b) a CaCl2 soln. to form CaSO4. The amt. of CaCl2 depends on that of Na2SO4 and the vol. of (A) depends on amt. of CaSO4 pptd., flow rates and decantation speeds. In a second zone, (B), are continuously introduced (c) a crude NaCl brine contg. impurities, at 50-80 degrees C and (d) a soln. of NaOH and Na2CO3 to ppte. impurities in mixts. (a) and (c). (c) is introduced under press. so as to produce at the bottom of (A) a low-press. zone which induces aspiration upwards of liq. leaving (A). Sludges are continuously removed from both liquids and the purified brine is recovered from the top of (B). All stages of purificn. are done in a single, divided tank and by reducing CaSO4 content in the mother liquors, the consumption of CaCl2 and Na2CO3 is reduced. The process is easily adjusted to changes in flow rates and impurity contents.

Title: Steroid pharmaceutical dosage unit - consisting of a steroid solution in a soft gelatin capsule
IPC: A61K31/565
Filed: 1975-05-07
Abstract: Pharmaceutical dosage units for steroids contain at least one pharmaceutically active steroid (e.g. progestogens such as norethynyltestosterone or oestrogens such as ethynyloestradiol) and a solvent therefore (pref. an acetoglyceride, an esterified vegetable oil, polyethylene glycol, polypropylene glycol or isopropyl myristate) in a soft gelatin capsule. Steroid dosage units (e.g. oral contraceptives) generally contain very small amounts of active ingredient, and it is difficult to produce tablet formulations contg. exactly the required amount of active ingredient. The new dosage units permit accurate and consistent distribution of active ingredient in the liquid phase so that it is relatively simple matter to ensure that each unit contains the required dosage within predetermined tolerance limits. In addition, the soft gelatin capsule formulations give better or more rapid release of active ingredient in artificial gastric juice than is the case with tablets.

Title: Pressure or distance measurement using ultrasonics - involves compressible medium in which propagation velocity dependence on density is known
IPC: A61B5/03
Filed: 1975-07-17
Abstract: The method determines a pressure or a distance in a compressible medium whose external dimension or density, respectively, are known. The relationship between the velocity of propagation of ultrasonic waves in the medium and its compressibility and density are assumed to be known. An ultrasonic signal is transmitted through the medium and measurements are made of propagation time, thus enabling propagation velocity to be calculated. The ultrasonic frequency is of the order of 100 kH2. A reference measurement may be made using a signal at 10 MH2; at this frequency the pressure in the medium has negligible effect.

Patent FR-2296584-A1 (FR)
Inventor: JOHNSON OLIVIER D
IPC: B65H3/52
Filed: 1975-11-10
Abstract: A document transport and separating device which utilizes opposing intermittent motion imparting devices having tips, the end of which are caused to move in an elliptical manner to feed, separate and align documents such as sheets of paper. One end of the tips of the devices are caused to move in an elliptical manner through a combination of application of an intermittent force parallel to the longitudinal axis of the tips of the device at its other end coupled with a rotational movement about a mounting spring which converts the longitudinal force into the elliptical motion. The longitudinal force is applied by pulsing a solenoid or electro magnet. The tips of the opposing devices are flattened at their point of intermediate contact to prevent multiple sheet feeding and greater surface contact and the coefficients of friction of the flattened tip surfaces are greater than the coefficients of friction between each of the sheets such that sheet feeding occurs. However, the coefficient of friction of the upper or feeding tip is greater than that of the lower or restraining tip to provide the dual function of both separating and transporting a sheet. Alignment of the tips such that the elliptical rotation of their ends is at an angle to the path of the paper allows alignment of a sheet of paper against a transport rail for both proper separating, transporting and alignment of a sheet.

An enclosed heat exchanger is connected to the enclosed chamber, the connection and the enclosed heat exchanger being located above a level of the volatile liquid within the enclosed chamber, whereby the volatile liquid is evaporated within the enclosed chamber by heat generated within the power cables. The evaporated liquid is transferred by virtue of a pressure differential from the enclosed chamber to the enclosed heat exchanger, wherein the evaporated volatile liquid is condensed and from which it flows by gravity back to the enclosed chamber.
Patent FR-2340423-A1 (FR)
Title: Local irrigation device using dew formation - has sealed hollow sphere contg. soln. with volatile solute and absorbent block supported in gas zone
IPC: E03B3/28
Filed: 1976-02-03
Abstract: The dew ball (11) may be used for local irrigation in a region with a continental temperature range and high air humidity. Several balls (11) may be arranged on a grill so as to drop dew water into a hole contg. sapling roots. The ball uses endothermal phenomena associated with a volatile binary solution within a sealed container and subject to external temperature fluctuations. It may contain quantities of water-ammonia solution, liquid ammonia (19) and ammonia gas. The solution is absorbed in a porous block (16) within the gas zone. As air temperatures rise ammonia gas separates from the solution, raises internal pressure and causes further gas to condense and increase the liquid fraction (19). The reverse process occurs as air temperatures drop causing the temperature of the liquid ammonia to drop rapidly.
Patent FR-2340188-A1 (FR)
Title: Blow moulding is internally cooled by circulating mist - supplied and extracted through internal ducts in blowing mandrel
IPC: B29C49/58
Filed: 1976-02-09
Abstract: Blow moulding machine is used for making plastics articles and comprises a core mandrel on which a plastics blank is placed and then transported into the blow mould. Equipment is provided on the mandrel to enable a gas-entrained mist of liq. to be injected into the blow moulding while in contact with the inner surface of the mouls, in order to cool it rapidly. This mist circulates into the moulding through the mandrel and returns out of it also through the mandrel. The mist-circulation arrangement pref. comprises inlet ducts discharging at openings on the side of the mandrel into the mould cavity, and outlet ducts which have their inlet openings at the extreme tip of the mandrel. The mist thus circulates through the entire length of the blow moulding. By circulating a cooling mist, e.g., fine water droplets entrained by air, the cooling time of the blow moulding is considerably reduced. Since this cooling time is normally longer than that for blow moulding and removing of the moulding, a redn. in cooling time enables the entire cycle time to be reduced.
