Title: Improvements in or relating to electric ship propulsion
IPC: H02P7/34
Filed: 1930-01-15
Abstract: 349,012. Dynamos and motors combined for transmitting power. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, WILSON, J. C. and CARNEGIE, H. S., Siemens Works, Stafford. Jan. 15, 1930, No. 1430. [Class 38 (iv).] Ships having two or more propelling means and provided with means for varying the relative speeds of the propelling means have the generator and motors driving the propellers excited from a separate source and are arranged so that the variation of the relative speeds is effected by field control of one motor, or set of motors, at a time, the regulating means for the remaining motor or set of motors being inoperative while the generator field is varied proportionally but not reversed. As shown in Fig. 1 the propeller-driving motors B, C have their armatures connected in series with the generator armature A. The fields of the three machines are excited from an exciter D. Control of the motors simultaneously is effected by means of the potentiometer 2 across which is connected the generator field 1. The fields 3, 4 of the motors C, B are connected to potentiometers f, g across the terminals of the exciter D. A rheostatic regulator H in the generator field circuit has a contact 25 mechanically coupled to contacts 21, 22 and 23, 24 associated with the potentiometers f, g respectively. The fields 3, 4 are brought out to contacts 11 .. 18. Considering the action of the regulator f; at the position shown in Fig. 1 both motor fields are connected across the full exciter voltage. Upward movement of the contacts 21, 22 reduces the motor field until the position q is reached when the motor field 3 is unexcited. At the same time the contact 25 on the generator regulator H has moved upward to insert resistance 9 in the generator field circuit. Further upward movement of the contacts 21, 22 results in the reversal of the motor C with increasing field until the position r is reached when the motor C is on reversed full speed, and the resistance 9 in the generator field is all out. The contacts 23, 24 at the same time have moved upward to positions q<1>, r<1> but as the end contact 8 on the potentiometer g is connected to a strip 8a no change has been effected in the speed of the motor B. Similarly the speed of the motor B may be reduced and reversed with a corresponding variation of the generator field while motor C remains on full speed. Fig. 2 shows an arrangement whereby the rheostatic regulator 4 in Fig. 1 is dispensed with and resistances 29 .. 32 connected as shown. Variation of the voltage across the exciter fields 3 or 4 by the method described above thus results in a variation of resistance in series with resistance 29 or 31 with a corresponding variation in the drop across the resistances 30 or 32 and a consequent variation of the generator field. In the case of two or more generators the fields, regulators and limiting resistances are connected in parallel and the armatures in series.

Title: Improvements relating to the cooling of cement clinker
IPC: F27B7/40
Filed: 1938-01-18
Abstract: 509,611. Cooling cement. RONNE, E. Jan. 18, 1938, No. 1697. [Class 51 (ii)] In a rotary kiln process for the manufacture of cement the clinker is cooled rapidly immediately after sintering from a temperature of about 1300‹ C. to a temperature of 1100- 1200‹ C. by mixing it in the kiln with already cooled clinker, which may be the clinker from the same kiln after it has been cooled down to 200‹ C. or below. In the apparatus shown, the hot clinker from the kiln 1 is discharged into cooling-tubes 2 surrounding and rotating with the kiln, and the discharge ends of alternate tubes are connected by helical pipes 4 with feed openings 7 immediately below a dam ring 8 situated at the hottest point of the sintering zone. The inlets to the pipes 4 may be controlled by sliding plates, and as a considerable length of the pipes will be filled by cool clinker, entry of air through the openings 7 will be prevented. In a modification, the tubes 2 are so arranged that their discharge ends lie adjacent the end of the sintering-zone, and in this case, a direct connection can be made for the return of cooled clinker. These connections are closed by flaps which are opened to allow passage of the clinker into the kiln only when the ends of the return connections are beneath the charge.

Abstract: 1370261 Shoes for internal drum brakes L FRIEDMAN 15 Jan 1972 2005/72 Heading F2E A device for use in clamping opposed brake blocks 112 (for large vehicles) to brake shoes prior to a heat-bonding process, in which device the brake blocks are to be confined under pressure against brake shoe tables 110 having struts 144, includes a spreader element comprising a pair of spaced parallel pressure plates 124 each having an arcuate edge to fit and bear against the inside surface of one of the brake shoe tables outside the struts 144 on the table, spaced means 126, secured to and extending between the pressure plates to space them and each having an inner surface 142 facing away from the arcuate edges to serve as a load-bearing surface, leaf-spring means 130, 134, spanning and overlying the load-bearing surfaces 142, and means 136, secured to the leaf spring means to co-operate with another such spreader element to maintain a relative position between the spreader elements when in a clamped position. As shown, an expander platform 100 has fixed expander unit 102 and movable expander unit 104, these units being notched at 106 to permit a spreader screw 108 and the tube 136 to be slid into place. The assembly is surrounded by a stainless steel band 114 overlapped and welded together at the bottom 115, and reinforced by a welded plate 116 at the top. Each of the spaced means 126, in the form of a plate, extends beyond the chordal edges of pressure plates 124 and forms a loop 132 with a U-shaped rod 128 to accommodate the leaf spring 130. On the left, tube 136 and spring-retaining plate 138 are fastened to the spring, while on the right screw 108 and a similar retaining plate are similarly secured. When hydraulic pressure is applied to a piston and cylinder unit 154, the expander unit 104, connected to the piston-rod (not shown), is forced to the right, thereby flattening the righthand springs 130, 134, and causing band 114, via the left-hand shoe table assembly, to flatten the left-hand springs against fixed expander unit 102. Then a nut 137 on spreader screw 108 is run up against the end of tube 136 to hold the parts in this position. When the assembly is placed in an oven (not shown) and the temperature is raised, the springs will retain some tension despite expansion of band 114.

Abstract: 808,732. Photographic roll-film cameras. KAFTANSKI, F. Jan. 24, 1956 [Jan. 24, 1955; Dec. 28, 1955], No. 2242/56. Classes 98 (1) and 98(2) In a photographic roll film camera, an outward movement of a sliding plate tensions the shutter drive spring and operates an exposure counter and an inward movement feeds the film and returns the shutter to a position in which it co-operates with shutter release means. Preferably, the sliding plate extends longitudinally from the camera body and co-operates with a sliding plate shutter. As shown, the shutter is set when plate 3 is pulled out of the camera body in an upward direction, the shutter plate 35 being held back by catch 13 of the shutter release plate 12 so that shutter drive spring 40 is tensioned. Spring arm 45 enters the teeth of an exposure counter indicating disc 9 mounted on the camera body, towards the end of the upward movement and operates the counter. A spring tongue enters the teeth of the disc to prevent a reverse rotation and the disc thus holds plate 3 against the tension of spring 40. In this position aperture 50 in plate 3 provides uninterrupted view through the viewfinder (Fig. 2, not shown) and an aperture having a ring 39 extending between the objective 5 and the exposure chamber is positioned in the optical axis of the objective 5. On releasing shutter plate 35 by depressing shutter trigger 15 the exposure is made as aperture 37 coincides with aperture 39 and plate 35 comes to rest with pin 43 abutting the rim of the plate. On moving plate 3 downwards into the camera, claws 29 engage the film perforations and film 21 is changed. In the lowermost position of plate 3 red window 49 is interposed in the view-finder optical system, indicating that the shutter is unset, and the body of plate 3 acts as a safety shutter covering lens 5. The camera body may consist of front and back mouldings of plastic material the join between them providing a guideway for plate 3. A tripod bush may be provided at the lower end of the body and may be used for attaching a pen or pencil to the camera. For stereoscopic photography two cameras can be secured to a flat plate, the releases being simultaneously operated by a bar co-operating with their release triggers. The free end of a pocket clip may extend through an aperture in the camera body to operate the release.
