Title: A collapsible pushchair frame with a central spine
Inventor: PEARCE SAMUEL BLACKBURN
IPC: B62B7/08
Filed: 2008-07-02
Abstract: A collapsible support frame for an infant pushchair comprises an elongate spine centrally located between, and coupled to, a pair of elongate support limbs. The spine 12 and the support limbs 14, 16 are curved to define a seating cavity in which to receive a flexible seat. The spine is coupled to the support limbs via a coupler 20 and at or towards its other end via a handle assembly 22. The support frame further includes a pair of support arms 24 extending from the coupler, and each support arm also pivotably carries a wheel 28. The wheels of the support frame in its erect configuration are spaced from each other and provide ground engaging support below the seating cavity. The spine and support limbs are foldable (figures 2a-c) and each support arm is linked to the spine and a respective support limb such that the support frame is collapsible in a single movement into a collapsed configuration in which the support arms are pivoted relative to the coupler to locate the wheels adjacent each other, and the spine and support limbs are folded to lie adjacent each other and adjacent the support arms.

Title: Sequential synchronization in a tree of networked devices
Inventor: BRANDON HIEB
IPC: G06F11/14
Filed: 2009-05-28
Abstract: Nodes in a network are configured into a tree structure. Nodes may have one or more child nodes and may have one or zero parent nodes. When information on the topmost parent node in the tree is changed, the data is synchronised with the each of its direct child nodes in turn. The child nodes then synchronise the information with each of their children in turn. The first child node may synchronise the data with its children at the same time as the top most parent node synchronises the data with its second child. The order in which the child nodes are synchronised may be based on a synchronisation level. The tree structure may be reconfigured by adding or removing nodes. If a node is removed which has child nodes, one of its child nodes is selected to replace it.

Title: Self-aligning open-hole tractor
Inventor: AGUIRRE FRANZ
IPC: E21B4/18
Filed: 2008-02-04
Abstract: A downhole tractor assembly (fig 1) that is configured for open-hole applications and of a self-aligning nature. The self -aligning nature of the assembly is effectuated through a tractor portion (150) which is rotable about an axis (180) of an elongated body (100) of the assembly independent of a separate centralizing portion (175) of the assembly. That is, the tractor portion, configured for interfacing an open-hole well wall (250) of potentially irregular morphology, is independently rotable so as to maintain a position of substantially optimized driving friction at the interface during tractoring. Maintenance of optimized driving friction in this manner may occur irrespective of the orientation of the centralizing portion of the assembly.

Examples are given for the production of the dyes.  They may be incorporated into synthetic linear polyesters by mass-coloration techniques to give orange to green shades.  The polycyclic dyestuff compounds of Formula (I) may be obtained by condensing the appropriate compound of the formula D-(Z)n with an aniline carboxylic acid or mercaptobenzene carboxylic acid.

Title: Automatic temperature control system
IPC: G05D23/275
Filed: 1944-05-26
Abstract: 590,219. Automatic control systems. POLLAK, J. E. (Vapor Car Heating Co., Inc.). May 26, 1944, No. 10258. [Class 38 (iv)] Temperature.-In a system involving a plurality of thermostats with auxiliary heaters functioning at different temperatures for controlling the temperature of an enclosed space, the auxiliary heaters for the several thermostats are connected in a circuit such that the current supplied to them can be uniformly varied to adjust their associated thermostat settings without changing their relative spacings. In the form shown a railway car has an overhead ventilating system which can provide heated or cooled air according to the temperature, also a floor heating system which normally is used only when the other system is inoperative, but under some conditions the two systems can function together, e.g. when the external temperature is abnormally low. The floor is heated by steam through the normally open valve 11 which, however, is closed by energization of winding 53 through relay contacts 32, 33 but these contacts are open at low temperatures when relay winding 25 is energized. At a predetermined temperature, this winding is shortcircuited by thermostat 12 mounted in the car and the floor heat is thus cut off. This thermostat has a heating coil 45 in series with a resistance P the value of which can be altered manually when it is desired to change the temperature at which the thermostat functions. There is also a second resistance, not shown, in this circuit which is cut out by another thermostat when the outside temperature is excessively low. A generally similar circuit but with a normally closed valve, controls the operation of the overhead system while two further thermostats cause cooling of the air in this system in either one or two stages depending on the internal temperature. The temperatures at which the thermostats controlling the overhead system function are also adjustable manually and automatically but the running of the blower circulating the air in the overhead system is not thermostatically controlled. The manual adjustments of the thermostat auxiliary heaters referred to above are made by a double deck potentiometer P, P<1>, Fig. 3 (not shown) so that the thermostat settings are adjusted simultaneously, the differences between the settings of the various thermostats remaining unchanged.
