Title: Improvements in or relating to methods of and means for drying bark tanned leathers and the like
IPC: F26B21/02
Filed: 1932-12-28
Abstract: 412,919. Drying bark-tanned leather &c. WINKELMULLER, K., 5, Saalfelder Strasse, Leipsic, Germany. Dec. 28, 1932, No. 36720. [Class 34 (ii).] Bark-tanned leathers and the like are dried by passing them through an unheated ramming space, exposing them in a connected space to low but gradually increasing temperatures and a transverse air circulation of low but gradually increasing pressure, and treating them in connecting space at high temperatures, which decrease towards the outlet, and a transverse air circulation of higher pressure. The process may be carried out in an apparatus consisting of a channel-like casing 1 on the ceiling of which two endless chains provided with removable leather-holding crosspieces 4 are arranged. The casing is divided into six zones in the second and sixth of which fans 6 are disposed on the casing at the top ends of chimneys 7 extending laterally from the centre of the ceiling to the bottom of the channel and communicating with the inside of the latter through the lower parts thereof. By the operation of the fans 6 transverse air currents are maintained through the chimneys 7 and horizontal suction ducts 8 into the casing 1 as shown. By providing a plurality of fans with means for regulating them and for putting one or more out of action, the air pressure can be varied as required, both from zone to zone and longitudinally in each zone. Heating pipes 9 in the chimneys 7 warm the circulating air. In the second zone the heating devices are built so as to increase the temperature from the beginning to the end, and in the sixth zone are arranged to give a maximum temperature in the centre. In the third, fourth, and fifth zones no heating or air circulation takes place. The third and fifth zones are provided with air discharging chimneys for removing moist air, which by co-operation with the fans 6 causing transverse circulation produce resultant spiral air currents in the second and sixth zones, in opposite directions to one another. The air circulation in the sixth zone is more powerful than that in the second. The longitudinal motion of the air can be regulated by means of a more or less tightly closing curtain at the entrance to the first or ramming zone, together with air openings fitted with adjustable shutters at the transition between the first and second zone. Smaller chambers are provided at the beginning and end of the casing for attaching and detaching the leather pieces.

Abstract: 1380670 Dish washers G BAUKNECHT GmbH ELEKTROTECHNISCHE FABRIKEN 2 Aug 1973 [9 Aug 1972] 36798/73 Heading A4F In a dish washer, a lower spraying pressure in the circulating washing liquid is achieved by the introduction of air at the intake of a centrifugal pump. In order to avoid air spaces forming on the pressure side of the pump with consequent damage to seal 12 due to hot running of the pump, one or more passages 17 is/are provided in the hub of impeller 9. Thus on rotation of the impeller 9 by shaft 10 washing liquid is directed to spaces 15 even when air is introduced at the intake nozzle 3 of the pump 4. The air is introduced via a pipe 13 having a valve 14, the consequential lowering of pressure allowing more delicate washing to be effected. The cross-sectional area of each opening 17 is between 0.1 and 10%, preferably 1 % of the area of the impeller.

Title: Acceleration sensitive mechanism
IPC: G01P7/00
Filed: 1963-09-23
Abstract: 999,194. Accelerometers. BENDIX CORPORATION. Sept. 23, 1963 [Sept. 27, 1962], No. 37387/63. Heading G1K. [Also in Division H2] An acceleration responsive instrument for measuring the distance travelled by a moving body after it has been given a predetermined acceleration comprises a biasing mass 25, a seismic mass 26, a double integrating mechanism 39, 40, 48 restraining movement of the mass 26 and switches 49, 51 operatively connected to the mass 26 through the integrating mechanism determining respectively the initial motion and the completion of movement of the mass 26. A separation distance switch 10 responsive to acceleration along an axis x-x, comprising a bias mass 25 and a seismic mass 26, is arranged to arm a missile after it has travelled a predetermined distance say 9, 000 ft. from an aircraft, the distance being derived from the acceleration of mass 26 by double integration through fly wheel mechanism 40 and premature arming being prevented by inhibiting movement of mass 26 until mass 25 overcomes the preset bias of spring 30 at a predetermined acceleration of say 3 g. Before firing, an electrical signal is applied to terminal pins 16, 17 to ensure that monitor switches 53, 63 are closed. On firing a signal is applied to pins 18, 19 to operate solenoid 32 and withdraw latch 34, so that when an acceleration of 3 g is attained the inertia of mass 25 instantaneously overcomes spring 30 and an arm 59 actuates switches 53, 55, 57. This event is signalled over pins 16, 17 by the opening of monitor switch 53, the solenoid unlatch circuit is broken by the opening of switch 55 and its reset circuit is made by the closing of switch 57 so that the latch 34 engages face 86 of mass 25. Mass 26 is now free and as soon as it moves, a gear-wheel 48 moves switch actuater 67 to open monitor switch 63 and close inertia switch 65 to signal this event over pins 21, 22. When the mass 26 has moved the predetermined distance corresponding to 9, 000 ft, actuater 67 closes switch 51 to make the arming circuit over pins 23, 24, the circuit being held by locking the mass 26 with the latch 34 engaging its face 27. The compression of spring 30 is adjusted by turning a cap 29 to select the bias acceleration and the position of switch 51 can be adjusted-to set the separation distance.
