Title: Battery charger with initial intensive charging - has final reduced charging with intermediate charging by switching between charging states
IPC: H02J7/00
Filed: 1973-07-03
Abstract: The electric battery charger has a current supply (1) with two levels (11, 12) of output current which can be selected by a selector circuit (2). The selector circuit (2) is excited by a circuit comprising a comparator (3) which can detect a difference between the voltage of the battery (4) and the reference voltage at a potentiometer (5). When the battery voltage is equal to the reference voltage, the comparator (3) switches the selector circuit (2) between one level of output current and the other level by means of a NAND gate (6), a counter (7), and two inverters (10, 11). The counter (7) determines the duration of charge at this intermediate level. Two other counters (40, 41) are excited by another NAND gate (51) and connected to the comparator (3) and the first counter (7).

Title: Telescopic jib crane overload protection system - compares jib angle derricking force with permissible maxima
IPC: B66C23/90
Filed: 1973-12-28
Abstract: A derricking ram acts between the crane superstructure and the jib, and the lifting force exerted by the ram at this point is measured, as is the jib angle. The actual angle is compared with the maximum one at which the lifting force measured can be exerted without overloading the jib, or conversely the actual force exerted is compared with the maximum which can safely be exerted at the particular angle measured. Depending on the result, jib movement is either allowed or stopped, whatever the jib length and the weight of the load on the hook. The jib angle can be measured from the horizontal, from a datum line on the superstructure, or from the direction in which the derricking force acts.

Title: Sewn mink tails for making garments - with zig-zag seams to reduce fur waste and improve appearance
IPC: A41D5/00
Filed: 1974-03-05
Abstract: Each animal tail esp. mink tail is split longitudinally into two tapering lengths which are sewn together alongside each other to make a single piece with fur on one side and the inter-length, tapering gap filled with a leather inset. A number of such pieces are sewn together as a rectangular strip with the pieces angled at about 45 degrees to the strips longer side, several of the strips then being sewn together at their longer edges to form the sheet. Essentially, the two lengths of each split tail are rejoined in longitudinally offset relationship so that each piece has a stepped edge remote from the inset; each strip then has a zig-zag long edge which is mated, brick-bond fashion, with a corresponding zig-zag edge on the adjoining strip, the strips, being sewn together along this zig-zag joint. A sheet of fur is produced from which the garment trade can produce coats coats, cloaks etc. Much less fur is wasted in trimming to make the joints between strips, e.g. up to 98% of original fur is utilised. The zig-zag seam between strips does not tend to produce obvious 'partings' in the fur of a garment, as did the previous straight seams.

Title: Process and appts. for breaking oil emulsions - by freezing followed by melting and decantation
Inventor: GRUET WILLIAM
IPC: B01D43/00
Filed: 1974-12-27
Abstract: Process for breaking an emulsion can be used not only for the sepn. of an oil emulsified in water but also for the sepn. of all solid or liq. prods. emulsified, dispersed or dissolved in a liq. The process consists of freezing then melting and finally allowing the mixt. to settle. During freezing it is necessary for the liq. to freeze whilst trapping the smallest possible amt. of the particles of the prod. and the particles should be pushed towards the surface and/or towards the base, according to the density of the prod.; this is facilitated by slight mixing and vibration of the mixt. during solidification. When the prod. has collected at the bottom and/or at the surface of the tank it can easily be sped. into prod. and liq. The cycle can be recommenced if it is necessary to obtain a purer prod. The appts. used comprises a tank, a pipe system traversed by the refrigerating liq. and a heating system. The appts. is low in initial cost and in operation; it will break all emulsions of the soluble oil type without the necessity of a preliminary study of the emulsion.
