Title: Improvements in or relating to fluid dynamometers
Inventor: REYNOLDS ROBERT BASSETT
IPC: G01L3/20
Filed: 1948-11-30
Abstract: 657,786. Rotary-absorption dynamometers. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Nov. 30, 1948, No. 31081. [Class 106 (ii)] Apparatus for absorption and measurement of power of the type in which a fluid is employed to transmit torque to a floating stator is characterized in that the rotor is supported between bearings axially separated by the rotor only, there being no fluid seal between the rotor and its bearings. One fluid supplied to the dynamometer provides for both lubrication of the bearings and transmission of torque from the rotor to the stator, the supply of fluid being contained in a closed system in which the fluid circulates and which includes a heat exchanger for extracting heat from the fluid. The fluid which is preferably lubricating oil may be separated into bearing lubricating and torque transmitting supplies the former being pressurized relatively to the latter so as to oppose flow of the latter toward the bearings within the dynamometer. Further, the viscosity of the fluid supply to the dynamometer may be varied, by control of the effectiveness of the heat exchanger so as to vary the power absorption of the dynamometer. The rotor 7 has integral stub-shafts 9 which are mounted in journal bearings 10 supported by the outer members 4 from the casing 2. These journal bearings 10 are arranged in close axial proximity with the rotor 7 and are provided with rotor locating pads 11 which bear on the sides of the rotor. Although the bearings 10 are each provided with a fluid lubricant supply channel 12, no seal is provided between the bearing lubricant and the torque transmitting fluid in the cavities 5, since the same fluid lubricant is used for the latter purpose also. By this arrangement which allows a shorter shaft to be employed, higher rotational speeds may be achieved. Seals 13 are provided at the outer ends of the rotor shaft 9 to oppose leakage of fluid from the machine.

Title: Improvements in or relating to a device for extracting bakery products from open top baking containers
IPC: A21B3/18
Filed: 1948-12-01
Abstract: 657,577. Conveyers; tipping apparatus. STEVENS, A. H. (Purity Bakeries Service Corporation). Dec. 1, 1948, No. 31132. [Classes 78 (i) and 78 (iv)] [Also in Group VI] Bread &c. is extracted from its set of baking pans 23 by dropping the pan set into an L- shaped tilting frame 52 where it strikes against a bottom impact-bar 56 to loosen the bread. The frame 52 then tilts over clockwise by gravity until the pan set falls against spaced intercepter bars 57, Fig. 4, so that the bread is knocked out of the pans and falls through between the bars 57 to a deflector 68 from which it drops to a bread shoot 63 which delivers it in upright position to a conveyer 64. A stop 59 assists in the jarring action to release the bread. The frame 52 then tilts back counter-clockwise to drop the empty pan set on to a shoot 66 leading to a pan conveyer 67. This tilting back puts the frame 52 into position to receive the next pan set from the inclined guide 42 at the delivery end of the conveyer 17. A light tension-spring 62 pulls the frame 52 back counter-clockwise into the pan-receiving position. Where varying weights of pan sets are to be used the tilting frame 52 is moved through its clockwise tilting by the plunger 81 of a solenoid 78 energized by a switch 79 when struck by the pan set falling into the bottom of the frame 52. When the frame 52 has been pulled over fully clockwise by the solenoid its other arm 51 opens switch 82 to de-energize the solenoid so that the frame 52 is uprighted by the spring 62 only. The solenoid &c. may also be arranged to perform both the tilting and the uprighting of the frame 52. The tilting &c. of the frame 52 may also be done by a compressed air cylinder and plunger, the air valve of which is actuated by a solenoid coupled to control switch 49, Fig. 8 (not shown). The bread in the pans is originally delivered from the baking oven, Fig. 2 (not shown).

Abstract: 535,348. Printing machines. CHAMBON CORPORATION. Dec. 1, 1939, No. 31273. Convention date, Dec. 10, 1938. [Class 100 (ii)] A multi-colour intaglio or other printing or coating machine which is especially adapted for printing from marking materials such as thermo-plastic compositions which are liquid when heated and solid when cooled, is constructed with means for heating the printing cylinders 20 uniformly by circulation of liquid first through the cylinders and then through the jackets 48 of the ink fountains 45 which are heated to a temperature lower than the printing-cylinder. The machine may be used to carry out the process described in Specification 515.437, and the cylinders 20 may be fitted with spring-pressed scrapers 56 heated by electric coils 56b, and arranged to receive heat from the jackets 48. The impression cylinder may be heated or cooled by circulating liquid. The heating liquid is admitted to the cylinders 20 by means of pipes 22 with ports 35 leading to the interiors of the cylinders, and the return takes place through concentric pipes 37 passing through plugs which cut off the inlet channels from the outlet ones. The pipes 37 connect to inlets 53 for the jackets 48 which are formed with baffles 47 and are surrounded by air spaces closed by insulating sheets 49. The cylinders 20 are fitted with baffles 36 to secure uniform heating. The scrapers 56 are mounted in holders 56a fitted in slots in shafts 57 controlled bv adjustable springs and journalled in arms 58 secured to lugs on the lower frames of the printing-machines, which comprise also upper frames 16 pivoted to shafts 17 and held in place by adjustable hook members 90 engaging notches in the lower frames so as to permit the upper frames to be turned aside to permit of access to the fountain 45. Each impression cylinder 20 is mounted so that it can be readily tripped either by hand or automatically when the machine stops. The cylinder 20 is mounted in slides 28 pressed upwards by springs 70 and normally pressed downwards by the action of cams 74 on slides 71 fitted with spring plungers 72. The cam shaft 73 is acted on by coiled springs tending to rotate the cams to a position in which the springs 70 raise the slides 28, but a catch 82 locks the shaft 73 in operative position. The catch 82 can be operated by hand or by a solenoid 86 which is energized when the machine stops.

Abstract: 1353638 Swimming pools W AMANN 6 July 1971 [18 Feb 1971] 31678/71 Heading A4N A swimming pool, which is fabricated in a form such that it can be disassembled and transported, comprises an enclosure of which the walls are each constructed of a plurality of vertically extending slats 6 which abut each other along their lateral edges, a holding-frame 5 surrounding said slats at a height of approximately 1/3 the distance from the bottom of the slats, the upper and lower edges of said slats being disposed in upper and lower channel members 9, Fig. 3, and a waterproof lining 4, Fig. 1, disposed within the enclosure. The holding-frame is assembled of force-fitted tubes of rectangular cross-section of synthetic plastics or metallic material. The frame is reinforced and held by lateral supports 7, and struts 8 which extend transversely below the bottom of the swimming pool. The walls of the pool may be both stiffened and strengthened by using the channel members 9, by inter-connecting and inter-locking the adjacent surfaces of the slats 6 with groove (1) and torque (2) Fig. 5 (not shown), and by bolting each slat to the holding-frame using a Z-shaped fitting (3). The upper edge or rim of the swimming pool can be covered with prefabricated elements (10), e.g. synthetic plastics or stone plates, which are glued with cement (15) Fig 4 (not shown) to the upper, U-shaped channels 9. The plates (10) are roughened to decrease the possibility of bathers slipping on them and the edges are preferably bent downward, the plates also serving as a seating-edge and a border toprevent water spilling over the edge of the pool during bathing. The absolute depth of the pool may be increased by using slats having two differing  lengths. Fig. 6 (not shown) illustrates the formation of the slats such that adjacent units intersect telescopically. Furthermore, the holding-frame 5 surrounding the pool functions as a step or standing surface and thus facilitates entering the swimming pool.
