[Class 132 (iii)] A constructional set comprises panels or plates of different shapes and sizes including some of L-shaped section, each with an inturned lip on at least two opposite edges, and connecting members, each with complementary inturned lips on opposite edges so that the panels may be joined by the connecting pieces which are slid on to the edges of the panels. Each panel 1 has at least two inturned lips 3 overlying and spaced from the face of the panel. If these lips are on adjacent edges they stop short of the corner between these edges. In some panels all the lips overlie the same face whilst in others some overlie one face and some the other. Some panels may be of L-shaped section as shown in Fig. 2. Instead of being flat, the panel may be angular, as shown in Fig. 7, or curved. One or more of the rectangular panels may be formed with an opening simulating a door or the like and may actually be provided with a hinged door or the like. Various locking bars 2 are provided, each being strip-like with two inturned opposed longitudinal margins 5 to engage the lips 3 on any two of the panels, and therefore usually being of C-section as shown in Fig. 10. The bars may, however, be bent along their centre line so as to join the panels at right angles as shown in Fig. 13. Some bars may be elbow-like, being bent intermediate their ends, with inturned lips along their long edges which terminate short of the bend. At the ends of the bars there may be clips to clip the bar to another bar perpendicular to it. Clips, such as 7 in Fig. 16, may be provided for hooking on to panels 1 and bars 2 and these may be provided with holes to receive shafts or axles such as 8 or 9.

Filed: 1951-04-20
Abstract: 693,321. Photographic shutters. KODAK, Ltd. April 20, 1951 [April 22, 1950], No. 9267/51. Class 98 (i). In a multiple pivoted blade shutter having a power-operated blade-driving master member releasable by manual operation of a trigger, different speeds are obtained by means of an adjustable gear retard train which is held with its elements in a predetermined relative position of rest by co-operation of a permanent magnet carried by a movable element of the train with another adjacent permanent magnet fixed to the shutter. As shown, the shutter is substantially identical with that described and claimed in Specification 650,874. The retard train comprises a star wheel 52 to which is attached a magnetized disc 51 having its magnetic axis along a diameter thereof and a location-indicating notch disposed between the poles. By dropping the star wheel into the retard train with the magnetic axis substantially in line with a bar magnet 72 secured in the shutter, the movement of the retard always includes the same amount of play so that'the shutter can be accurately timed to chosen values by suitably shaping the timing cam (not shown), which determines the position of the gear segment arm 61.

A method of producing dehydrated fried potatoes comprises frying potato pieces (e.g. chips, dices or balls) e.g. at 110-140C. in groundnut oil, to cook the pieces and form thereon a crust which is permeable or substantially impermeable to water and water vapour, freezing the pieces to below -10C. and lyophilising the frozen pieces to reduce their water content to below 8% by weight. The impermeable crust is made permeable either before or after freezing by subjecting the hot potato pieces to an abrupt vacuum to swell them and form cracks in the crust, by puncturing the crust with pins or by removing part of the crust. The potato pieces may be frozen by use of high vacuum or an air stream. The potato pieces may be treated, before frying, in a bath of sulphurous, acetic, citric or ascorbic acid to stabilize their colour. The dehydrated potato pieces may be rehydrated in cold or hot water and fried before use.
