Abstract: 784,106. Electron microscopes. VEB. C. ZEISS JENA. Aug. 9, 1955, No. 22947/55. Class 39(1). A cartridge for the specimen slide of an electron microscope enables the slide to be tilted into two positions for taking stereoscopic pictures. The cartridge 2 fits in the specimen table 1, and its annular end-cap 3 has two inclined surfaces 4, 5, upon which rests the specimen slide 6. A manually operable slide 7 bears on one edge of the slide 6 and a free member 8 bears by gravity on the other so that the slide can be rocked about the knife-edge between surfaces 4, 5. A pin and slot connection 9, 10 between member 7 and the cartridge allows the latter to be removed from the table 1. As shown in Fig. 2, the lid 11 of the air-lock antechamber is pivotally and resiliently connected to an angle lever 14 through a piston and cylinder assembly 12, 15, the end of the lever 14 being hooked onto member 7. A further resilient stop 21, 22 near the main pivot 13 of the assembly has a small permissible movement between stops sufficient to give the member 7 the travel necessary for tilting to two positions. Further movement of door 11 causes the removal of the cartridge.

Abstract: 583,707. Making cased hollow-ware. ELKINGTON & CO., Ltd., and WEAVER, W. J. Nov. 20, 1944, No. 23026. [Class 83 (ii)] In a method of making cooking and like vessels having an inner lining and an outer covering of different metals, blanks of the two metals are superimposed and formed into the shape of the vessel by deep drawing, which operation also inseparably unites the two layers. A liner blank 1 of nickel and an outer covering blank 2 of copper are superposed and are drawn together to form the shape of a saucepan to which a handle or handles may be secured. If desired the liner blank may be larger than the blank of the outer covering, the upper extending edge of the liner then being rolled over the upper end of the outer member at 5 to form a strengthening and decorative finish. Two forms of rolled edge are shown in Figs. 5 and 6. In cases where a comparatively deep vessel is to be made the blanks may be partially shaped before being superimposed for the final shaping operation. A foil of bonding material such as tin may be interposed between the two blanks.

Title: Improvements in or relating to refractory lined metallic wall structures
IPC: F23M5/06
Filed: 1954-08-09
Abstract: 759,430. Flue pipes. DETRICK CO., M. H. Aug. 9, 1954 [April 15, 1954], No. 23059/54. Class 25. [Also in Groups XII, XXVIII and XXIX] A refractory lined metallic wall structure for furnaces, heaters, ovens, flues, ducts, and various types of vessels, comprises a steel shell 32, metallic brackets 33 welded thereto and each formed with a platform 35 and an upstanding finger portion 37, supporting refractory blocks 46 of generally T-shaped section seating at the ends on the platform 35 and having lateral slots 56 engaging the fingers 37, and supported refractory blocks 63 with offset portions 67, 68 at each end forming shoulders 69 engaging the shoulders 51 of the supporting blocks. The blocks 46 and 63 thus form alternate horizontal rows with flush-front faces spaced from the steel shell 32. the space at the rear being filled with plastic refractory 61 behind the blocks 46 and with insulating blocks 62 behind the blocks 63. The plastic refractory may also be used to fill any gap formed between blocks 62 and 63. The wall is completed by base blocks 44 on supporting material 45. The finger 37 of the bracket 33 may be replaced by a low flange, Fig. 6 (not shown). The invention may be applied to cylindrical walls, Fig. 19 (not shown), in which case the gap between the steel shell and the blocks is simply filled with plastic refractory material. When applied to a curved tapering wall, Fig. 20 (not shown), e.g. a conical or a concave wall, the blocks 46 are tapered upwardly and the blocks 63 are tapered longitudinally. Since the blocks 46 are inserted downwardly over the fingers 37 in these latter constructions, the last block is split in a substantially diagonal direction for ease of insertion into position.

Title: Improvements in or relating to remote control devices
IPC: G05D1/02
Filed: 1962-06-15
Abstract: 958,094. Leader cable systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 15, 1962 [June 20, 1961], No. 23129/62. Heading H4U. [Also in Division G3] A leader cable system for controlling the movement of vehicles comprises a route defining cable g carrying an alternating current and on each vehicle a pair of coils A, B spaced apart on the longitudinal centre line of the vehicle and associated with amplifying means arranged so that the voltage output derived from coil B is greater than a voltage output in the opposite sense derived from coil A when the coils are equally spaced from cable g, means for obtaining the algebraic sum of a comparison voltage which determines the distance between the cable and the longitudinal centre line of the vehicle and the two derived voltages and a steering motor which is energized to correct the position of the vehicle when the resultant voltage is above or below a predetermined value. The voltages induced in coils A, B are amplified and rectified in units V 1 , V 2  respectively. The gain of unit V2 is greater than that of unit V1, and the unit provides an output signal in the opposite sense to that produced by unit V1. The output voltages and a comparison voltage supplied from a tap on potentiometer P are summated in the input circuit of an amplifier V3 which provides an output voltage to control a constant frequency, constant amplitude oscillator O When the vehicle is correctly positioned the voltage from amplifier V3 is arranged to control the oscillator such that the positive and negative portions of its square wave output are of equal duration and this signal when amplified in unit V4 produces no movement in a steering motor SM. When the voltage from amplifier V3 is above or below the predetermined value the duration of the positive and negative portions of the oscillator output differs and the steering motor is driven to correct the position of the vehicles. The motor is also coupled to the tap on potentiometer P and when driven alters the value of the comparison voltage in a manner which reduces the sum voltage at the input of amplifier V3 and hence damps the operation of the system. The comparison voltage may be switched to a different value by operation of contacts C1, C2 controlled by relay R and since this voltage determines the distance between the cable and the longitudinal centre line of the vehicle, a first vehicle may be overtaken and passed by a second vehicle when the vehicles are differently controlled by relay R.

Filed: 1924-10-03
Abstract: 245,202. Rees, T. J., and Ford, A. F. Oct. 3, 1924. Skid.-Vehicle brake mechanism of the kind comprising scotch blocks or skid pans adapted to be lowered into engagement between the wheel and the track, to prevent the vehicle running downhill comprises, according to one construction, Fig. 1, a transverse shaft provided with a pair of crank arms 2 carrying blocks 1 and rotatably mounted in vertically slotted guides 5 secured to the chassis. Springs 7 are interposed between blocks 8, 9 disposed in the slots, the block 8 bearing on the shaft, which is thus able to move upwardly against the springs to compensate for variation of load or inequalities of the track when the blocks are applied. The blocks are normally held raised by a hand or foot controlled rod 13 connected to an arm on the shaft. The blocks are adapted to fall into engagement with the wheels by their own weight, which is, however, partly counterbalanced by weights 13a on arms extending from the shaft. Fig. 4 shows another construction in which the arms 37 carrying the blocks 1 are slidable against the action of springs 39 in the tubular end parts 36 of the shaft 34 mounted in brackets 35. The blocks are normallv held raised bv cables 41 connected to arms 42 on the shaft. Two pairs of blocks and operating mechanism therefor are provided in this case, adapted respectively to check forward or rearward movement of the vehicle. Skid pans may be used instead of blocks of the form shown. The blocks may be formed as an aluminium casting lined with friction fabric. For snow covered or frozen roads the under surface of the blocks may be serrated, such blocks being interchangeable with those for ordinary use. Blocks may be arranged for engagement with either the front or rear wheels. According to one of the Provisional Specifications, the blocks may be operated by electrical means and may be brought into engagement automatically whenever the vehicle is stopped.

Title: Absorption refrigeration machine
IPC: F25B15/06
Filed: 1970-05-14
Abstract: 1,234,920. Refrigeration. TRANE CO. 14 May, 1970 [16 June, 1969], No. 23493/70. Heading F4H. In apparatus for cold starting an absorption refrigeration machine utilizing a solution of lithium bromide absorbent in a refrigerant such as water, a heating fluid e.g. steam is supplied to a generator 18 at a predetermined rate in a preoperational preheat cycle to heat the absorption solution and the machine mass. The solution is circulated between the generator and an absorber 16 via a condenser 12 and evaporator 14 and after the solution has reached a predetermined temperature as sensed by an element 90 the preheat cycle is terminated. Thereafter the heating fluid is supplied to the generator at a variable rate responsive to demand for refrigeration as sensed by measuring the temperature of chilled water leaving the machine through a sensing element 86. The predetermined feed rate of steam is substantially the maximum output rate of the heat source and is normally constant. A control arrangement is particularly described with reference to Fig. 2.
Patent GB-1031945-A (GB)
Title: Gas turbine load sharing system
IPC: F02C9/42
Filed: 1964-06-08
Abstract: 1,031,945. Gas turbine plant. BENDIX CORPORATION. June 8, 1964 [July 5, 1963], No. 23706/64. Heading F1Q. [Also in Division G3] A control system for a bank of two or more turbo-shaft engines each having an output shaft driving a common load comprises a fuel control system which maintains constant the load sharing of the engines. As described, the two engines 10a, 10b, have output shafts 24a, 24b driving the common load and the measurement of the load carried by the shafts is determined by the output pressures of the compressors 12a, 12b. The output pressures are fed through lines 50a, 50b to act on one side of diaphragms 100a, 100b respectively and to a selecting valve 110 which delivers the higher pressure in the lines 50a, 50b to passage 112 to act on the other side of both diaphragms 100a, 100b. A difference in the pressure in lines 50a, 50b occurs when the load sharing between the two shafts vary and, assuming that the pressure in 50b exceeds 50a, the diaphragm 100a moves to the left to act on a valve lever 82a to vary the loading. The valve lever is normally loaded by a spring 84a adjustable by a normal throttle control 90a and is moved by a centrifugal governor 76a driven by the speed of shaft 24a. The lever 82a controls a leak valve 88a controlling leakage from a chamber 44a, fed from the lines 50a through a restrictor 54a. The pressure in chamber 44a acts on the outside of a bellows 42a while the pressure in a chamber 46a, connected to line 50a acts on the inside of the bellows 42a and an evacuated bellows 40a. Movement of the bellows assembly 40a 44a acts through linkage 34a to adjust a valve 32a. The pressure in chamber 44a can also be varied by a value 62a which is opened by a centrifugal governor 66a in the event that the compressor rotational speed exceeds a predetermined value. The engine 10b is provided with a similar fuel control system. Variation in the load sharing thus varies the loading on the appropriate lever 82a 82b which effectively varies the spring loading of the appropriate governor 76a, 76b to adjust the fuel supply to restore the load sharing. If the engines are not identical with regard to performance an adjustable bleed may be provided in the lines 106a 106b to balance the control systems. The load measurement may alternatively be measured by speed, temperature or any other suitable parameter.

Title: Improvements in or connected with mechanism for the conversion of rotary into reciprocating motion and vice versa
IPC: B06B1/10
Filed: 1923-03-01
Abstract: .212,155. Spence, W. L. March 1, 1923. Actuating by weights.-The rams of pumps are reciprocated by the inertia of paired bob-weights rotated synchronously in opposite directions in the same plane on rigidly tied axes at rightangles to the direction of reciprocation, the bob-weights being rotated by right and left handed worms on a shaft slidably coupled to a rotary driving-shaft. As shown in Fig. 3, three sets of bob-weights set at 120‹ to each other are driven by duplex worms slidable on a splined driving shaft and the reciprocating motion is utilized to drive three pumps R<1>, R<2>, R<3>. This arrangement may also be used as an hydraulic wave transmission generator having a three-phase action, or, conversely, if a three-phase impulse is given to the rams the apparatus may be used as a three-phase motor, in which case the splined shaft is driven with practically uniform torque. Single and double phase action may be obtained by varying the angle between the pair of bob-weights. A pump operated by bob-weights may be used in a hydraulic press, or combined with a constantstroke hydraulic motor it may form a variable gear applicable to automobiles. The strokes of the pump may be controlled by gravity, and, or, springs. When the bob-weights are driven at constant speed the stroke of the plunger varies inversely as the resistance and gives a quick light load stroke and a slow heavy load stroke. The pump is not injured by overload, and the delivery may be shut off so that the driving motor may be started up on light load.

Title: Improvements relating to artificial limbs
IPC: A61F2/58
Filed: 1919-09-29
Abstract: 155,917. Anderson, W. P., Clarke, N. C., and Whitelaw, J. F. Sept. 29, 1919. Limbs, artificial.-Comprises a disconnectable coupling for securing together two portions of an artificial limb, or for attaching artificial hands or tools to limbs, which may be used at any of the usual limb joints or at point intermediate of the usual joints. A socket connected rigidly to one member of the limb receives a spigot 2 carrying the other limb member or the hand or tool. The spigot is guided in the socket by a shoulder 3, and can be positioned axially so that balls 6 on the end of spring arms 8 engage with a circumferential slot 4 or with a ring of holes. A sliding sleeve 11 can be positioned to lock the spring arms in either position. The joint thus can be locked against rotation and withdrawal, locked against withdrawal with freedom to rotate, and unlocked so that it can be disconnected by an axial pull on the spigot. Various modifications are described. The sleeve 11 may rotate instead of sliding, and be provided with internal camsurfaces to effect the control of the spring arms. The balls 6 may be separate from the spring arms and be carried in cages in the socket so that they cannot escape therefrom. The ring of holes may be formed in the bottom of the slot 4. In this latter case, the spring arms are set so as to engage the groove normally and have to be forced inwardly by the sleeve beyond their normal set to engage the recesses.
