Title: Improvements in or relating to a system for determination of the longitudinal position of the center of gravity and the gross weight of a craft afloat, such as a seaplane
IPC: G01G19/07
Filed: 1944-12-08
Abstract: 596,302. Computing-apparatus. MARTIN CO., G. L. Dec. 8, 1944, No. 24628- Convention date, Dec. 1, 1943. [Class 106 (i)] [Also in Groups XX, XXXIII and XXXVIII] Means for computing the longitudinal centre of gravity and gross weight of a craft, such as a seaplane, while afloat comprises means for determining the draught at two or more spaced points and charts or indicators for obtaining approximate and then more accurate estimates. When a cap 11, Fig. 2, is removed the water passes up a tube 7 to raise a lioat 12 and project a scale 10 to indicate the draught at the point concerned. From the sum of the draughts at front and rear of a flying boat, an estimate of the gross weight is obtained from the lower part of the chart, Fig. 5, assuming the centre of gravity to be placed at a certain value of mean aerodynamic chord (M.A.C.). By taking this estimate of gross weight and the difference of draughts, a revised centre of gravity is obtained from the upper part of Fig. 5 and successive approximations in the lower and upper parts of Fig. 5 finally give agreement as to the values of the centre of gravity and gross weight. In Fig. 6, the water from outside the hull, enters a chamber 17. The chambers 17 of the fore and aft points are connected to pressure gauges, one of which adds and the other differences the pressures, Fig. 7. The dials 18, 19 of the gauges are rotatable by knobs 29, 32 so that successive approximations can be made before arriving at the correct values of the centre of gravity and gross weight. The gross weight, in a modification, may be estimated from the pressure in a single pressure chamber located amidships. The connections to the pressure gauges may be broken by a cock 37 (Fig. 7, and Figs. 10, 11, not shown), except when readings are being taken. In Fig. 12, the pressure chambers are replaced by floats 51<1>, 52<1> actuating potentiometers 45, 46. A fourpole switch 47 in position A connects the potentiometers in series to indicate the gross weight on meter 48. In position B, the switch 47 connects the potentiometers in parallel so that the meter 54 indicates the centre of gravity. The dials are adjusted as before.

Title: Improvements in or relating to the manufacture of ice confections
IPC: A23G9/10
Filed: 1961-07-07
Abstract: 1,020,922. Ice-making. J. OLDHAM. Sept. 17, 1962 [July 7, 1961], No. 24650/61. Heading F4H. Frozen confections with associated confection-holders are removed from moulds by applying a lifting tension to the confection while subjecting the mould to a defrosting medium so that when defrosting is completed the confection is immediately lifted from its mould. As shown, moulds 3 containing frozen confections are supported in containers 6 which are supplied from a conveyer 1 to a supporting frame 12 which is disposed above a tank 13 containing hot water and below a lifting device 25. Each confection has a projecting stick 8 which is held in a stick holder 7. When a container 6 is in position on the frame 12 it engages an air valve 38 which causes a pneumatic lifting assembly 15, 16, 17 to lift the tank 13 and so immerse the container 6 in hot water. As the tank reaches its raised position it operates a second air valve (Fig. 2, not shown) which causes the lifting device 25 to tend to lift bars 30, which engage projections (not shown) on the stick-holder 7, and so apply a lifting tension to the confections 9. Thus when defrosting is completed, the stick-holder 7 and confections 9 are raised from the moulds. When rising the stick-holder 7 operates a third air valve 39 which causes the tank 13 to be lowered, and on reaching its upper limit of travel a part of the lifting device operates an electric switch 42 which energizes a motor 36 driving a conveyer 34. The latter has projections 35 which engage and move the stick-holder 7 from the lifting device 25 to guide-rails 33, and when clear of the device 25 the stick-holder engages an air valve 41 to return the lifting device to its lowered position, and an electric switch 43 which stops the motor 36. A further conveyer 32 is used to remove the empty moulds from the frame 12.
