IPC: A63H11/08
Filed: 1920-10-11
Abstract: 169,388. M³ller, H. Oct. 11, 1920. Mechanical toys.-A human or other figure is constructed to turn somersaults or, when mounted on a stand, to revolve round the axis of its arms. The toy is driven by a fly-wheel which is set in motion by a multiplying train of gearing. The body n of the toy is fitted with a casing a enclosing the driving-gear and through which the axis b of the long arms c passes. The axis b is flattened at m, Fig. 3, and engages springs in a casing k connected to a pinion e geared through wheels f, h, i with a fly-wheel S loose on the axis b. The fly-wheel is set in motion by turning the arms c relatively to the body, the springs l slipping if the turning is effected too strongly. If the toy is placed on a table, the fly-wheel when moving causes the figure to turn somersaults. The arms may be connected by sleeves r, Fig. 4, to the upturned ends q of a frame o which serves as a stand. The stand is provided with a hook t bv which it may be hung on a nail or suspended from a cord. The upper part d of the arms c are curved to form shoulders as shown in Figs. 1 and 2.

Title: Process for the preparation of phthalic acid esters
Inventor: LAFONT PIERRE YVES ANDRE
IPC: C07C69/80
Filed: 1965-07-07
Abstract: Hydroxyalkyl esters of a phthalic acid are prepared by reacting a phthalic acid with an alkylene oxide in an inert organic diluent at 100-150 DEG  C. in the presence of a triorganophosphine as catalyst. The process is preferably carried out under pressure using two moles of alkylene oxide to each mole of phthalic acid.

Abstract: 1431796 Moulding ribbed tubes DAYCO CORP 19 June 1973 [3 July 1972] 29042/73 Heading B5A [Also in Division F2] A continuously moulded elastomeric hose, Fig. 2, comprises a wall of solid section defined by an inner tubular layer having a circular interior surface 13 and external annular, or a helical rib 14 fused thereto and of a material which is harder than that of the tubular layer, e.g. of substantially twice the hardness. The rib or ribs may comprise a material having a Shore durometer hardness of between 80 and 100 on the"A" scale, with the hardness of the material of the tubular layer being between 40 and 60. The ribs may be partially embedded in the tubular wall, e.g. as at 20. The materials may be thermoplastic, thermosetting, or natural or synthetic rubber. The hose is formed by delivering the material into a cavity defined between a pair of moulding devices 23, each comprising mould halves 26 which are pivotally interconnected at 27 and move along an endless path. For forming the Fig. 2 hose, the material comprising the ribs 14 is delivered from one extrusion source 45 to be injected, via a passage 46 and annular outlet 50 of an extruder mandrel 38, into annular rib defining grooves 33, formed in an interior surface 31 of the mould halves which slide along an exterior surface 51 of the mandrel. The material comprising the tubular wall 12 is delivered from another extrusion source 36, via a mandrel passage 37 and spider 44, to be extruded into fusing intermingling contact with the rib material, at an annular outlet 42 of the mandrel. Downstream of the outlet 42 the mandrel exterior surface 43 is spaced from the mould halves surface 31 to define the thickness of the tubular wall 12. To avoid heat loss from the material, thermally insulating sleeves 59, 63, 57 are detachably fastened to the apparatus. For producing the Fig. 3 tube (not shown), the mould halves define a single helical groove (33A), Fig. 5 (not shown). The extruded tube may pass from between the mould halves, through a cutter, to a wind-up mechanism.

Abstract: 648,036. Energy and power meters. MEASUREMENT, Ltd., HEWLETT, S. J., and BIBBEET, J. A. Nov. 10, 1948, No. 29195. [Class 37] In an A.C. power or energy meter, an induction disc a is rotatable by opposed torques exerted by driving elements c, b which are respectively energized by currents derived from the line current in one phase of the system and from the output of a valve f amplifying the output of an induction regulator coil d rotated by disc a in an electromagnetic field e energized by one phase voltage. The voltage coil i of a wattmeter or watthourmeter is supplied from the same phase voltage, and the current coil h, is connected in series with the driving element b and the amplifier output. The disc a assumes a position wherein the driving torques balance, the amplified output from coil d in phase with the line voltage is proportional to the line current, and the meter indicates apparent power irrespective of the phase difference between line voltage and current. The induction regulator may be replaced by a variable capacitor in series with a larger fixed capacitor. or the induction disc may operate follow-up contacts and a servometer to rotate the regulator coil, which may energize the driving element and the meter current coil directly without amplification. For unbalanced 3- phase measurements, the phase-correcting device may be duplicated in conjunction with a 2-element wattmeter. The Provisional Specification refers to the use of a magnetic amplifier, and direct driving of the regulator by the induction disc through reduction gearing.

A digital computer includes apparatus for allocating and deallocating small memory blocks to a computer program. Each memory block is subdivided into a number of equal sized miniareas, each block being described by an area status word (ASW) which defines the base address of the block, the size of the mini-areas, and the availability/non-availability of the miniareas of the block. When an object program requires memory space, it is interrupted and a Master Control Program searches the ASW's to find an available block having the right sized areas and, if one is not present, a new block is formed having an ASW defining the required memory block. The object program is then returned to. When the program no longer requires a memory block the block is deallocated and its ASW removed. Allocation. Fig. 2 and Figs. 1 and 3 (not shown).-The object program specifies the size of the memory block required and if it is below a certain size, e.g. ten words, then a GET routine is executed using a clock controlled sequence counter (Fig. 1, not shown). If it is greater than ten words, then the Master Control Program utilizes a conventional get space routine to allocate space in memory. The ASW words are compared in turn with the memory block request and, if a desired block is not available, a new memory block is allocated. Fig. 3 (not shown) is a flow diagram for placing the new ASW on the ASW list. Deallocation (Figs. 4 and 5,n ot shown).-To deallocate a memory block below a certain size, e.g. ten words, a FORGET routine is executed, using similar circuitry to the allocation routine.
