Title: Mechanical/hydraulic transmission system
IPC: F16H47/04
Filed: 1974-07-12
Abstract: 1423125 Variable-speed gearing HYDROMATIK GmbH 12 July 1974 [24 July 1973] 31086/74 Heading F2D  A continuously variable transmission system operable in a first mode, in which power is transmitted wholly through hydraulic means, and in a second mode in which power transmission is divided between the hydraulic means and mechanical gearing comprises, in one form, an input shaft 10 geared to a variable displacement hydraulic machine 201 and to a member 13  rotatable relatively to a shaft 32 which is geared to an output shaft 11, and a variable displacement hydraulic machine 202 connected hydraulically to the machine 201 and mechanically to a shaft 16 with sun wheels 25, 28. The displacement of machine 201 is variable in positive and negative senses from a neutral or zero displacement condition, and that of the machine 202 is variable between maximum and minimum displacement in one sense only. For operation in the first mode the machine 201 is set to zero displacement, 202 to maximum displacement, a clutch 14 is disengaged, and a positive brake 15 is applied to prevent rotation of a planet carrier 31. As the machine 201, now acting as a pump, is adjusted towards maximum displacement in either sense, corresponding to forward or reverse rotation of the output shaft 11, power is transmitted by the machine 202, acting as a motor, through the sun wheel 28, planet wheels 29 held against orbiting by the brake 15, and ring gear 30 which is fixed to the shaft 32. Maximum output speed in this mode is achieved when 201, 202 are at their maximum and minimum displacements respectively. To increase the output speed in the forward direction, the brake 15 is released and the clutch 14 engaged, such change-over being triggered, e.g. by a switching device 17. Power is now transmitted in part mechanically through the clutch 14, ring gear 27 and planets 26 carried by the ring gear 30 fixed to the shaft 32, and in part through the ring gear 30, planets 29 and sun wheel 28 to the machine 202, which now acts as a pump, and 201, acting as a motor. Output shaft speed is increased further by adjustment of 201 through its zero displacement condition to its maximum displacement in the opposite sense, when it again functions as a pump and 202 functions as a motor. A one-way clutch may take the place of the brake 15. A modification has a different arrangement of mechanical gearing, including intermeshing plants, one sun wheel on the shaft connected to the machine 202, a second sun wheel on a shaft connectible by a clutch with the wheel 22, and a brake acting on a ring gear.

Abstract: 703,924. Changing display devices. DUNNETT, D. Dec. 20, 1951 [Dec. 21, 1950], No. 31114/50. Class 3(1) A display device comprises an upper layer' of liquid 2 and a lower layer of liquid 3 in a transparent container 1, the two liquids being non-miscible and the upper layer being of lower specific gravity than the lower layer and means 9 for heating the lower layer so that it rises through the upper layer in the form of liquid bubbles or as a liquid column which breaks into such bubbles, the bubbles being cooled by the upper layer so that they return to the lower layer. The container wall has a dark coloured area 7 near its base which absorbs heat from a lamp which forms the heating means so as to heat the liquid 3. Bubbles then rise through the liquid 2 from an aperture 5 between the top of a sloping plate 4 and the wall of the container. When the bubbles eventually fall they pass through an aperture 6 between the lower end of the plate 4 and the container wall. A light coloured reflecting layer 8 is provided in the wall of the container above the heat absorbing layer 7. The container and lamp stand on a heat insulating base 12 and heat and light from the lamp are concentrated on the container by a reflector 10. The liquid 3 contrasts in colour with the liquid 2. A detergent may be added to the liquid 3 to assist bubble formation and a solute to the liquid 3 to adjust its specific gravity.

Filed: 1950-12-22
Abstract: 688,996. Resistance measuring. EVERSHED & VIGNOLES, Ltd. Dec. 20, 1951 [Dec. 22, 1950], No. 31256/50. Class 37. An earth resistance measuring apparatus comprises a crossed-coil ratiometer whose deflection coil D, Fig. 1, is fed with a rectified voltage obtained from electrodes E, P2 defining the earth resistance X to be measured and through which flows A.C.; a variable resistance 18 is adapted to be put into the A.C. circuit so as to increase the voltage supplied to the coil D, the resistance 18 being adjusted to give a predetermined ratio between the deflection with the resistance in circuit and the deflection with the resistance out of circuit, thus enabling X to be measured in terms of resistance 18. As shown in Fig. 1, a D.C. hand-driven generator 1 feeds the controlling coil C of the ratiometer, and over a reversing device 2 energizes the earth circuit E-C2 with A.C. ; a mechanical rectifier 3 feeds the deflection coil D through limiting resistances 28, 30; when switch S1 is closed the resistance 18 is out-of-circuit, and ganged switch S2 is closed short-circuiting resistance 30; when switches S1, S2 are reversed, resistance 18 is put in circuit and simultaneously coil D is shunted by resistance 29; resistance 18 is then adjusted until the ratiometer recording is unaffected by the operation of switches S1, S2 and the value of X calculated from the value of 18 and the effect of the shunting resistance 29 on the meter. Thus, if resistance 29 halves the current in coil D, the resistance X equals resistance 18. In Fig. 1, the resistance X is defined at one end by the earth plate E. In Fig. 2, the earth energizing electrodes C1, C2 are both separate from the electrodes P1, P2 defining the resistance X, and the energizing circuit includes the primary 35 of a transformer whose secondary is shunted by the resistance 18 and can be switched at S1 to add an additional deflecting voltage to that derived from PI, P2. The primary 35 is tapped to enable the ratio of the transformer to be varied and thus the effect of resistance 18.

Title: Improvements in and relating to the casting of sanitary earthenware
IPC: B28B1/26
Filed: 1948-12-04
Abstract: 653,232. Endless conveyers. JOHNSON, J. A. Dec. 4, 1948, No. 31436. [Class 78 (i)] [Also in Group V] In an installation for casting sanitary earthenware, the articles in their moulds 16 travel along a moving main conveyer 11, Fig. 1, and are supported, wholly or partly, in a tilted position by supports 15, Fig. 4, carried by a lower auxiliary conveyer 12 travelling parallel with, and at the same speed as the main conveyer. The moulds 16 are assembled on the gravity roller conveyer 10, and filled with slip from a pipe (not shown). Each mould then moves forward along the main conveyer 11 at a very slow speed, e.g. 7¢ inches per minute for about 90 minutes. After this casting up time has elapsed, the mould is drained in two operations to let surplus slip run out. In order to release slip trapped in the pedestal in the same way that water is trapped in everyday usage, the mould is tilted on to supports or cradles 15, Fig. 4, consisting of side frames with cross-rails 15a carried by the auxiliary conveyer 12. The auxiliary conveyer may be driven either by gearing from the main conveyer drive or by a separate motor 13 and reduction gear 14, Fig. 2 (not shown). The mould travels in the fully tilted position for the length of the auxiliary conveyer and is then tilted back on to the conveyer 11. The mould is then carried through a drying oven 17 and the article is dried to the green stage. On passing to the conveyer 18, which runs at a higher speed than the conveyer 11, work is carried out on the article which is then passed through an oven 19. This oven encloses the final part of one straight length and the first part of the second straight length of the conveyer system, in addition to the connecting gravity. bend. The higher speed is maintained in the oven 19 and the article is dried to the leather hard state. On emerging, the mould passes on to a belt 20 running at a still higher speed, where the mould is separated from the article and reassembled on the conveyer. The article is then green fettled. The article and the mould next enter a third oven 21, on a belt which may run at the original very slow speed, for final drying of the article to the white state. Emerging from this oven the article is fettled and removed whilst the mould passes on to the conveyer 10 for re-use.
