Title: Improvements relating to the administration of medicaments and the like
IPC: A61D7/00
Filed: 1965-05-04
Abstract: A removable sponge for intravaginal administration in domestic animals is impregnated with at least an ovulation-controlling dosage of a progestational compound, which dosage may permit the induction of ovulation at a determinable period after discontinuance of its use.  The fertility of domestic animals may be controlled by intravaginal administration of the impregnated sponge, followed by removal of the sponge prior to the time that insemination of the animal is to occur.  Animals that may be so treated include domestic farm animals, for example ewes, cows, sows, mares and goat does, and domestic pets, for example dog bitches and cats; examples describe the treatment as applied to ewes and cows.  The sponge may be made of relatively elastic, porous and absorptive plastics materials, especially polyurethanes of the polyester or polyether type; the sponge material may also be natural sponge, natural or synthetic rubber, polyvinylchloride and polyethylene.  A string may be attached to the sponge to facilitate removal.  Linen, cotton, nylon, polyolefine and polyester fibre strings may be used; monofilaments of nylon or polypropylene are preferred.  Suitable sizes and shapes for the sponge are given in the Specification.  Suitable progestational compounds include steroidal and non-steroidal compounds which are capable of controlling ovulation, for example progesterone and related compounds; numerous examples of such compounds are listed in the Specification.  The impregnated sponge may be prepared by dissolving the progestational compound, for example 17a -acetoxy-9a -fluoro-11b -hydroxypregn-4-ene-3,20-dione, in a low boiling point solvent, for example ethanol, applying the resulting solution to the sponge, and allowing the solvent to evaporate.  Antibiotics and bacteriostats, estrogens or androgens may be added to the sponge before or after impregnation.  The sponge may be inserted by hand or with the aid either of a duckbilled speculum and plastic rod or of a tapered plastics tube applicator and plastic rod.

Title: Improvements in or relating to the automatic or semi-automatic regulation of furnaces
IPC: F27B1/26
Filed: 1933-07-04
Abstract: 422,415. Regulating combustion in furnaces. L. F. T. FONDERIES, 36, Route de Flandre, La Courneuve, Seine, France. July 4, 1933, No. 18995. Convention date, July 5, 1932. [Classes 51 (i) and 51 (ii)] A method for the automatic or semiautomatic regulation of the air supply to a furnace 1 which consists in feeding air to the furnace by an arrangement similar to that described in Specification 374,847 comprising a nozzle 5 connected to a fan (not shown) and entering an open pipe 6 arranged coaxially with respect to the nozzle so as to leave between the nozzle and the open pipe an annular space opening to an enclosure 4 connected to the upper part of the furnace and to the stack 9, is characterized in that the fan delivers more air than is required by the furnace and in that the relative dimensions and positions of the nozzle and pipe are such that a portion only of the air enters the furnace, as indicated by the arrow 11, and the rest escapes to the enclosure and thence to the stack, as indicated by the arrows 12. Combustion products pass from the furnace to the stack by way of a pipe 3, the enclosure 4 and a pipe 8. If the rate of combustion within the furnace diminishes, the quantity of gases produced and consequently the pressure within the furnace also diminish, with the result that more air from the nozzle 5 is able to enter the furnace and thus combustion is accelerated. Similarly, if combustion is rapid, the pressure within the furnace rises and causes a reduction in the air supply. The fan may have two intakes, one for air and one for waste combustion gases taken either from the furnace 1 or from elsewhere.

Abstract: 1491969 Toothed gearing ROBERT BOSCH GmbH 6 May 1975 [7 May 1974] 19047/75 Heading F2Q [Also in Division F1] In a gear pump or motor, two rotors 15, 16 consist of toothed gear wheels meshing in external engagement, and, at least on one flank of every tooth on each wheel, the tooth profile is modified in a deviation from a simple involute profile by the removal of material near the crest of each tooth to provide a relieved portion 28, Fig. 5, the tooth arrangement being such that actual tooth-to-tooth contact becomes limited to a region on the flank near to the pitch circle, and the contact ratio only slightly exceeds a value of unity, for drive in one sense of rotation. In another embodiment, relief applied to both flanks of each tooth, Fig. 2, permits drive in both senses of rotation. Whereas unmodified involute teeth would theoretically have made contact from point a<SP>1</SP> to point a<SP>11</SP>, with a contact ratio of approximately two, the modified teeth in practice make contact solely over the path b<SP>1</SP> to b<SP>11</SP>, with the involute tooth geometry remaining otherwise unchanged. It is stated that this results in reduced friction and impact between teeth and a reduction in instantaneous torque fluctuations relative to those of unmodified teeth.
