Title: Cavity resonators for microwaves
Inventor: KACH ALFRED
IPC: H01P7/06
Filed: 1967-07-24
Abstract: 1,149,983. Coaxial resonators. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING A.G. 24 July, 1967 [25 July, 1966], No. 33846/67. Heading H1W. [Also in Division H2] Variation of frequency with temperature in a coaxial resonator 1 is compensated by the temperature-variable capacitance existing between a tuning plunger 4 and a bimetallic sleeve 5. The sleeve, which may be axially adjustable, is formed with longitudinal slits 6 which divide its free end into a number of bimetallic strips. These respond to temperature changes by bending radially. The temperature-dependent retroactive effect of a diode 8 in the output circuit 9 of the resonator is automatically compensated by virtue of the fact that both the retroaction and the degree of compensation increase with frequency. Compensation increases with frequency since the bimetallic strips cover a greater area of the tuning plunger as the frequency increases. The output impedance of the resonator is regulated by a plunger 10.

Abstract: 1,198,030. Musical instruments. ROVEX TRI-ANG Ltd. 15 July, 1969 [16 July, 1968], No. 33915/68. Heading G5J. In a toy piano with tuned elements which may be taut strings, flat strips, rigid tubes, or as shown, steel rods 12, each rigidly supported at one end, the striking mechanism includes an electric motor 24 which drives a rotary striker 28 and the striker is manually movable to different positions opposite the tuned elements. The rotary striker consists of a rigid arm 28 carried on the motor shaft 25 with a ring 29 loosely carried at each end of the arm. The striking mechanism is carried on an arm 17 pivoted at 18. The motor 24 connected to a battery 30 is energized by depressing the lower end of the arm 17 to establish contact between a contact carried on the arm and a curved contact strip 34 disposed beneath a curved slot (10, Fig. 1) in a keyboard marked in alternate light and dark bands (8, 9). A fingerpiece (11) is mounted on the end of the arm. Each steel rod 12 is tapered towards the end where it is rigidly held in a steel bar 14, the end being enlarged to engage tightly in a hole (16, Fig. 3). The fixed contact can be masked by insulating material so as to be exposed to the contact on the arm only when the arm is so placed that the striker will strike a single one of the tuned elements. Alternatively, the fixed contact may be formed as a printed circuit having a series of exposed contacts each in line with a tuned element.

Abstract: 776,885. Mine roof supports. GROETSCHEL, K. M. Nov. 24, 1954 [Nov. 25, 1953], No. 34066/54. Class 20(2) Channel section mine arch support members a, b which overlap at their ends are in direct or indirect contact only over the region of the middle of the side walls of the members. In Fig. 1 the webs of overlapping channel sectioned mine arch supports a, b, are offset to form pairs of steps c<SP>1</SP>, d<SP>1</SP>, and c<SP>2</SP>, d<SP>2</SP> between which inserts e<SP>1</SP>, e<SP>2</SP> are located in order to bear the clamping pressure between the sections. The inserts e<SP>1</SP>, e<SP>2</SP>are held by screw bolts f<SP>1</SP>, f<SP>2</SP> which extend through bores in either the inner member b or the outer member a as shown respectively on the left and right hand sides of Fig. 1. In Fig. 3 the webs are offset to form steps, such as c on the arch support a which bears upon a bar, such as g formed upon the other arch support b. The embodiments shown on the right and left hand sides of Fig. 3 differ in the relative disposition of the step and bars. On the right hand side, as shown in Fig. 3, a holding screw k passes through the outer arch support a into a groove between the bar g and the step on the web of the arch support b. A similar holding screw may be passed through the inner arch support b into the groove h' shown on the left hand side of Fig. 3. In the embodiment shown on the left hand side of Fig. 3, a clamp m may be engaged in the groove between the step and the bar g<SP>1</SP> on the inner arch support. In Fig. 4 non identical channel members a, b are held together by means of a bar o which extends in the longitudinal direction.

Title: Improvements relating to apparatus for arresting vehicles such as mine cars, tubs orthe like
IPC: B61K7/16
Filed: 1953-12-08
Abstract: 744,573. Railway stops. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and HARRIS, M. R. Oct. 29, 1954 [Dec. 8, 1953], No. 34109/53. Class 104 (2). In an apparatus for stopping mine cars, tubs or the like by an axle or wheel engaging resilient means the stiffness of the resilient means absorbing the shock is less for empty or lightly loaded vehicles than for heavily loaded vehicles. A stop member 6, pivotally mounted about a pin 10 on a frame 12, is raised or lowered by a pneumatic device 11 pressing a roller 9, through a link 15 and arms 17, 19 attached to a shaft 18, against the underside of the member 6. The control of compressed air to the device 11 is effected by manual operation. The stop member is of telescopic construction and has an outer member 28 and a hollow sleeve 2 closed at one end by a head 3. Within the stop 6 an abutment 25 formed with a forwardly facing projection 26, separates a light spring 27 and a heavy spring 22. When a lightly loaded vehicle wheel or axle strikes the head 3 the spring 27 only is compressed but with a heavily-loaded vehicle the spring 27 is compressed until the projection 26 abuts the head 3 and the load is then passed onto the spring 22. A plug .23 screwed into the member 28 extends into a slot 24 in the sleeve 2 limits the outward movement thereof. The sleeve 2 has a key 4 which engages a slot 5 in the member 28 and when in the inoperative position between the rail ends 1a, 1b the upperside of the member 28, the key 4 and the head 3 form a running surface for the vehicle wheels. In an alternative arrangement a light spring is arranged around the outside of and is slightly longer than the heavy spring so that the light spring is initially compressed and later the heavy spring. In further modifications a conical or a volute spring is used so that as the load increases the resistance of the spring increases.

[Classes 83 (ii) and 83 (iv)] Angular bending.-Multiple-ply metal tubing is made from strip stock by rolling up one edge, bending the strip axially reversely to the direction of rolling this edge, and rolling up the opposite edge of said strip prior to enclosing this latter rolled up edge within the first rolled up edge. The strip stock 1 drawn from a supply reel 2, Fig. 2, passes between preliminary rolls 3, 4 and 5, 6 and then to sets of rolls with three rollers in each set, three of the rollers 12 being arranged on axes at right angles to those of the corresponding pairs 10, the strip here takes the double-bent shape, Fig. 5, with a radius at A, a reverse bend, and a radius at C. The radius at A is held in the subsequent rolling operations while the radius C is bent around to form a complete enclosure, Fig. 11, when it reaches the rolls 18, 20, and this operation is continued to produce an overlapping portion when the rolls 29 are reached, Fig. 15. Finally the radius A is bent about the point B, Fig. 17, to enclose the overlapping portion already formed and thus to complete a self-sustaining multiple-ply tube, Fig. 23. Rolls such as 5, 6, 16, 17, 25, 26 may be driving rolls while the smaller rolls may be idlers. Strip provided with a coating of copper or other metal may be used and after formation into tube form may be passed through a furnace to melt the copper and seal the tube.

Abstract: 1400180 Holograms OPTICAL DATA SYSTEMS Inc 21 July 1972 [18 May 1972] 34333/72 Heading G2J [Also in Division G4] Rows of independent holograms are recorded on a film strip and the information contained in the holograms is retrieved by directing a light beam on to a selected row and moving the film parallel to the rows so as to scan the holograms of that row sequentially e.g. using an array of detectors to sense digital information. Credit card &c. verification. A watch list of numbers is recorded on a length of film 170, the numbers being distributed amongst the hologram rows in accordance with one or more of their most significant digits. A number to be searched for is entered on a keyboard, the most significant digit being used to position a mirror system 176 to deflect a laser beam on to the appropriate row of the film. The film is then driven in either direction and each hologram in the selected row causes an array of spots to be imaged on a detector array. Certain detector outputs are used to indicate sensing of successive holograms and initiate a digit-by-digit scan of the detector array for comparison with the keyed-in number. Detection of a match causes an indicator lamp to light up and may cause display of further information which is recorded in the hologram, e.g. customer credit rating; preferential treatment &c. If no match is found this may be indicated and the scan halted when a number which is higher or lower than the keyed-in number is found, the numbers being recorded in strict sequence. Computer programme input. The apparatus operates in basically the same way as above except that the keyed-in number may be supplied by the computer and a plurality of holograms including that identified by the input number may be read in sequence into the computer. Modifications. Operation as a store in which the film is driven to select a particular hologram for read-out, recording of pictorial rather than digital information, and the use of film in the form of an endless strip are mentioned. To check a customer's credit, a hologram on his credit card may be used to deflect a laser beam to the particular row on a film strip in which holograms of the appropriate account information are recorded.

Title: A new heparin-like compound
Inventor: BIANCHINI PIETRO
Filed: 1957-11-06
Abstract: The invention comprises a new heparin-like compound called ateroid which is a sulphomucous polysaccharidic acid having a metachromatic reaction with Toluidine-Blue, a critical micelle point of 0,455, a metachromatic density (relative to heparin=1,000) of 424, an anodic migration rate under electrophoresis of -4,44 X 10-5 an absorption peak in the U.V. at 204 mm , a strong hypocholesterolemic activity and a marked antilipemic activity.  Ateroid can be recovered by hydrolyzing a mammalian small intestine or duodenum, for example that of an ox, sheep, horse or pig, with alkali, preferably at a pH of about 8, to split off crude ateroid from proteinic matter, separating solid and colloidal material from the hydrolysate and precipitating crude ateroid from the hydrolysate at a pH of about 5.  Prior to the separation of colloidal material, the hydrolysate may be subjected to proteolysis.  In a preferred method, comminuted duodenum or small intestine is suspended in acid, the suspension is homogenized, the homogenate heated to 100 DEG C. for five minutes, allowed to cool, neutralized to pH 6,8 to 7,0, allowed to stand for 2 hours then acidified to pH 5, and separated into solid and liquid phases; the liquid is discarded and the solid dried, treated to remove fat, if desired, then comminuted and suspended in aqueous alkaline solution at pH 8 and heated for 15 minutes at 70 DEG -90 DEG C., filtered hot and the residue subjected, if desired, to further alkaline hydrolysis and filtered hot, the filtrates are then subjected to proteolysis, the volume is reduced to one-quarter of its original volume and dialysed, the dialysate is combined with acetone and the mixture is acidified to pH 5 to precipitate ateroid.  The ateroid may be further purified by forming a solution of ateroid in aqueous caustic alkali, filtering and precipitating ateroid from the filtrate by addition of an excess of a volatile organic solvent and acidifying to pH 5. The ateroid may be further purified by treatment with phenol.
